A Guide to Hiring Reputable Roofing Contractors in Tucson

This piece of writing: A Guide to Hiring Reputable Roofing Contractors in Tucson was initially seen on DCRoofingArizona.com

Considering how important a solid roof is, it’s no wonder that when you need to hire a Tucson roofing contractor, you want to make sure you’re making a solid choice.  You want professionalism, quality and affordability.  Making sure that you get everything that you want and deserve is an important task.

A roofing contractor doesn’t need a college education but should have the skills to get a job. A roofing contractor must have experience of at least two years before they can become licensed in most states, but there are exceptions. They also must be insured, bonded, and have a business license.

There are a number of reasons why you should definitely consider hiring a professional roofer over attempting any type of DIY project.  Surprisingly one of the biggest reasons is actually cost savings.

Saving Money on Your Roof

Many homeowners attempt roofing repairs on their own, but make costly mistakes that result in having to hire a contractor to fix the problem. Getting a professional roofing contractor has always proven to be the most cost-effective option. A reliable roofing contractor has forged long-term relationships with local suppliers, benefiting him from lower prices and enabling him to work more efficiently. The equipment he has enables him to finish the task more speedily and efficiently. It won’t take long to see how much you’ll save by finding a roofing contractor over DIY roofing.

And speaking of not taking long… that’s another advantage of hiring a professional!

Saves Time

You will have more time to attend to other priorities by hiring a professional roofer. Professional roofers work on timelines and are able to complete the assignment as fast as possible and progress to the next project. In roofing, experience counts a lot, so you can bet a contractor has spent some time in the field. A good roofer knows how to handle a wide array of roofs, as well as how to save time and money by taking the right approach. Additionally, a roofer’s artistry typically comes in handy in ensuring that your roof lasts for more than several years before it needs repairs again (as any roof eventually will).

So, what should you look for when hiring your roofing contractor?

Qualifications of a Roofing Contractor

The home improvement industry values roof installation as one of the largest and most important projects someone can do for their home. So it is critical that your roof is in great shape. It keeps you protected from the elements. Installing a new roof is expensive, so it’s best if you do your research before hiring a contractor.

Most roofing contractors learn their trade from on-the-job experience and no formal education is required to become one. Different states specify whether a roofing contractor needs a license to work on any job, while others may have specific limitations for non-licensed roofers. Georgia, for instance, requires roofers who work on jobs that exceed $2,500 to be licensed.

The average roofing professional needs a couple of years of experience to apply for a license. If he or she passes the exam, he or she can take the licensed exam through the State Licensing Board or through another government agency.  Making sure your roofer is licensed can give you significant peace of mind that the work will be done by someone who knows what they’re doing.

It is also important for roofers to have the following:

  • Liability insurance is a good idea.
  • An active business license is required.
  • Having a bond
  • A written estimate should be provided.
  • A minimum of three references should be provided.

Here are some great tips to keep in mind when looking to hire a roofing contractor in Tucson.

Look for longevity and professionalism

Whenever you visit a contractor’s website, it’s good to see signs of professionalism, such as a license number (ROC in Arizona), BBB accreditation and a decent number of good reviews on third party platforms such as Google, Yelp or HomeAdvisor.

Make sure you get references (and check them).

Consider dealing with a company with a good reputation that can back up its quality claims with references you can check. Seeing testimonials online is fine, but speaking with someone face-to-face is more trustworthy. Although positive reviews from Angie’s List and other sources are not to be ignored, a contractor worth considering might not have been reviewed there. This is why you might consider seeing some of the roofs that they have worked on in person when possible.

Check In with Your First Impression

When you have a roofer visit your house to examine your roof and put together a price, pay attention to his appearance and demeanor. Pride goes beyond the job site. If he doesn’t look clean enough to sit at your breakfast table, do you really want him working on your house?

You should then detail all the details and ask the foreman for his name and to whom the work will be assigned. Finally, write everything down.

Every quote isn’t the same.

Before a roofer can provide a bid, he needs to see the roof in question. You can expect each candidate to provide insights into the work involved, including your best options and the estimated time required. When the contractor refuses to give you a detailed estimate, move on to the next candidate.

Here’s how one meeting went as described by someone who did thorough research into hiring a good roofer:

They showed us several samples of the shingle product we were interested in. Then they told us about his company, started by his father-in-law, and about the eight-man crew that had been working together for eight years. It had everything from ice and water shield to site cleanup and warranty information. I knew I wanted him for the job.

After a week, a crew and a dumpster showed up at the house. The old roofing was removed in a few hours and plywood sheathing was put up. On the first day, more than half the work was completed. When it was complete, I couldn’t find a single nail even when I searched under shrubs in the garden.

Hearing past clients share such experiences gives you a better chance of having this kind of good experience with your own roofing project.

DC Roofing of Arizona is more than happy to provide references, photos and to meet in person to have a look at your roof and give you a free, no obligation quote to get you the roof you want.

Need a Roof Inspection? DC Roofing in the News Explaining the Process

You can discover the initial release of this particular blog post Need a Roof Inspection? DC Roofing in the News Explaining the Process here: DCRoofingArizona.com

As seen on DigitalJournal.com and USA Today’s AZ Central news site, DC Roofing discusses what you can expect during a roof inspection.

DC Roofing of Arizona, a roofing contractor based in Tucson, Arizona, has announced that they have recently published a blog post that explains what is looked at during a roof inspection. The article explains that having a licensed roofing contractor inspect the roof of a residential property will make sure there won’t be any unpleasant surprises regarding the roof. While it is definitely a good idea to have the roof inspected after the roof has been exposed to severe weather, roofs that are more than five years old may also need to be inspected.

It is typical to have the roof inspected before winter but in Tucson and other parts of southern Arizona, it is important to have the roof inspected before the monsoon season, where there could be heavy rain, strong winds, hail, and more. Just like with the winter season in northern climates where doing a roof repair is very difficult, if not impossible, the heavy rains and strong winds during the monsoon season also make it a challenge to have the roof repaired. Thus, it’s wise and recommended that homeowners have their roofs inspected before the monsoon season.

The question that homeowners often ask is what will the roof inspector look for during a roofing inspection. These include deteriorating shingles, indications of water damage, roof protrusions, and damaged flashing.

Roof shingles that are deteriorating or have curled are no longer effective. If the roof valleys and gutters are filled with shingle granules, that means that the shingles need to be replaced. The granules are designed to weigh down on the shingles and keep them in place. They also protect the asphalt material from being degraded by the ultraviolet radiation from the sun.

For flat roofs, it is important for the roof inspector to look for signs of water damage, such as areas where there is ponding or standing water because the water can speed up the deterioration of the roof. Other signs to look for are uneven roof planes, including the overall condition of the fascia, soffit, and gutter system. Clogged gutters or damaged flashing can also result in water damage in the same way as displaced shingles or tile where water can go underneath.

Roof protrusions, such as skylights, vents and other protrusions coming through the roof also need to be inspected. They should have a solid and effective seal. This seal must be inspected because it may deteriorate over time, possibly resulting in water leaks.

The roof inspector will also look for damaged flashings. Flashings that are separating, damaged, cracked, or incorrectly installed may result in roof deterioration due to the presence of water.

It is a good idea for homeowners who have a roof that is more than five years old get it inspected by a professional roofing contractor. This is important because in the event that signs of deterioration were found, the roofing contractor may be able to recommend the best way to provide the necessary repairs before they get more serious and costly.

Homeowners who plan to sell their house soon will also want to have a professional roof inspection conducted, in addition to a general home inspection. It is a good idea to have any potential problems fixed before a prospective buyer will try to make an issue about it and use it to bargain for a lower selling price.

If the inspection reveals that there is a need to have a new roof, having the roof replaced with a new one as early as possible is advisable. While a new roof requires a significant expense, acting on it quickly is recommended because the problem could worsen over time, resulting in an even higher cost for the roof replacement. Also, a report by the National Association of Realtors has revealed that homeowners were able to recover 109 percent of the money they spent on a new roof when they sold their home.

Asphalt Shingle Roof Inspection

When To Replace Asphalt Shingle Roof

Today we’re going to look at the process of looking at a newly installed asphalt shingle roof inspection for proper manufacturers installation instructions. We’ll look at what a roof inspector might look for and find, as well as some typical mistakes that are often made when asphalt roofs are installed.

The edge of the roof where the water runs off is called a drip edge. A drip edge typically there’s two or three problems with a new installation. One would be the starter course. The starter course is the course of shingles laid down first as a roof installation is put together. On top of that goes the first course, so well you typically see on the drip edge is the first course. The starter courses is actually just below it.

So what’s supposed to happen with this kind of roofing system, if the starter course is put down correctly, is that the first course actually adheres to it. The typical case of a starter course not installed correctly is obvious when there’s no adhesion of one to the other. The drip edge courses end up not being bound together like the rest of the courses will be.

The other issue is the felt underneath the shingles has no drip edge flashing. The flashing is a metal strip that basically just protects the piece of drip edge molding from water damage over time.

Some of the penetrations on a rooftop or other points of contingency when it comes to new installation, one thing that needs to be looked at is where the flashing is located. What I mean by flashing is basically that you first have “the boot”, which is the piece that the items penetrate through, then you have a piece of flashing that are usually nailed down, or stapled. In this case they’ve sealed over a nail head which is perfect. Over time those tend to leak.

Same thing on furnace vents and water heater vents. We have what’s called a storm collar, which basically protects the boot, or the piece below where the vent pipe penetrates through the roof. The storm collar should always be low over the joint and sealed. With a furnace vent, it’s same thing; making sure all the nail heads are sealed, and the storm collar is down tight as well.

Now chimneys are probably the one penetration in a roof that are known to leak the most. Something that often is found missing is the cricket. Crickets are required for building code on any chimney that is 30 inches wide or greater. In many cases you’ll see that you have a lot of surface area that is above the chimney, up to the ridge, where all the water is going to collect and divert down on top of this area. So a cricket is basically a piece of sheet metal, in most cases, or sometimes a constructed roof, and it diverts the water around the chimney to prevent it from blocking up. It also prevents debris from blocking up behind the chimney, which can cause damage. Another name for a cricket is also a saddle. No matter what you call it, the flashing on these should be nailed down and the nail heads should be sealed up.

The area of the roof where the water does not roll off is called a rake edge. Flashings are recommended, and drip edge flashings, like we discussed earlier, are required.

One of the most susceptible areas for water damage on a chimney is going to be the bottom corners. It’s very likely to find some water damage, and you want to be sure that if there is damage, it hasn’t just been shingled over and not repaired. In a lot of cases the guys that put these roofs on are in a hurry. They’ve got more jobs to do and the faster they can get this roof on, the lower the labor cost. The problem is, if you install the shingles in a way that exposes any type of nail head, this becomes a leak point. It usually doesn’t happen right away, but it can happen very quickly, depending on how the roof wears. Generally you will have water penetration at an exposed nail head maybe 10 to 12 years down the road.

What you should be looking for is to make sure there are no nail heads exposed around any shingles. Each section of shingles is called a tab. Another very important thing to look at is the way that the tabs are the shingles are fastened. You do that by just lifting up some of the new ones. As as the roof begins to get hot from the sun, the adhesive strip along the edge is going to glue down one tab and make it pretty hard to get up without damaging it. So looking at a roof on a cool day, or looking at a roof right after the installation is the best time.

The edge where the two shingles come together are supposed to be three-quarters over from the edge generally speaking. Something to look out for where these meet is how deep the nails has been driven into the roof. The problem if they get driven in too deep is that if a high wind were to get underneath it, very little of that nail head is left to be compressing down on the shingle, and the shingle can actually incur some damage. So by driving the nail head too deep, there’s the possibility of the shingle lifting off and away from the nail more easily, causing damage.

So as you go up looking at how the shingles have been nailed down, you’re going to want to look for consistent patterns as well as distances from the butt edge. Also, look for nails that might have been driven at an angle. It’s the same issue as before if the wind gets underneath the tab and lifts it, especially if the angle is pointing over toward the point of the shingle, then we do tend to have more wind loss. So checking these some areas at random is the best way to determine whether or not the roofer did a good job.

Something else to be aware of is that it’s not unusual to have a couple of different guys on site from the company doing a roofing job. So you might have one guy using nails and the other guy using staples. It’s the same issue with the staples – if you have the staple at a bad angle, it can be a problem because as the shingle comes up under the wind, if the staple is at an angle, it can actually tear across the shingle and it could come off real easy. To be right, inspect to make sure the staple should be parallel with this edge of the shingle going across. So we should see those running straight horizontally only. But again, these guys are often in a hurry and the idea is to get out of here as fast as they can without asking any questions, so they can get on to the next one. And often they’re not standing in a perfect location that allows them to hit these things straight, because of their wrist angle.

With a plumbing vent, you might see a hybrid rubber / metal flashing for the boot. In hot, sunny areas like Arizona, these aren’t the best way to go because they take on an enormous amount of UV radiation from the sun. Anything made of rubber like this is going to really get beat up by the sun. It’ll probably last the 20 years the shingles are supposed to last, but it wouldn’t be unusual to see them fail prematurely. Also the plumbing vent is supposed to be painted with the latex paint to prevent UV damage as well.

Don’t wait to learn that you have a roof leak by finding water on your floor – request that a professional roof inspector, who knows roofs backward and forward and understands how insurance coverage works, come and access your roof and help prevent future damage before it’s too late. Roof inspections today can save you a mountain of grief and work tomorrow.

Call around and you may even be able to find a local roofing business with inspectors who are willing to provide a free quote to check the health of your roof and look for needed repairs. Once things are in order, it’s a good idea to regularly have your house checked for potential issues through routine inspecting. In every community you’ll find professionals more than happy to go up and check the condition of your roof, report back and fix any problems before they turn into a major roof repair project and a potential safety hazard to your home and family.

Commercial Roof Repair Quotes

This article Commercial Roof Repair Quotes has been formerly issued on: dcroofingarizona.com

How Much Do Commercial Roofs Cost to Repair? Looking at the price quote process

We all know a commercial roofing project can be a daunting task. Today, we’re going to cover how technical reps customize a quote for you. So let’s walk through the steps of creating a custom roof quote.

After speaking to a prospective customer and establishing that they need a commercial roof repair quote, we’ll send our technician out to their location. we come out and do a field inspection on their roof in which we will pull cores out of the roof to determine the existing make up of the building’s roof.

We’ll ask some questions to find out what kind of roofing solution they have in mind. Things like what they’re looking for, what their real big problems are that they’re facing. Then we will take that information along with our measurements, and field drawings, and photos to be able to take it back to the office and pull a proposal package together.

When we get back to our office we’ll take that information and begin to compile it. And the first thing we want to do is develop the cost. Once we’ve come up with that number, we put together a scope of work for the building which will detail and outline, from start to finish, what we’re going to do on your building which will include all the different things that we are going to propose that need to be removed, replaced, changed, or gone over.

We break down all that data and try to determine what the best solution is going to be. Every roof is unique, so they’re not all the same. Each one has a different logistics challenge. Each one has a different insulation, or drainage, or multiple units on a roof, so each one is custom designed to that facility and to that owner’s needs and wants, so we take all that into consideration.

The package that is put together includes the survey report, a drawing of the roof, that may differentiate the different areas and different things that we found on the roof during the survey, to a comprehensive scope of work and proposal.

After that process is done, it gets sent to the customer or we deliver it to you and kind of explain and go over exactly what it is we’re proposing to do. The information can be presented in person or over the phone. Typically it’s sent through email process and then discussed in a phone meeting.

So once that roofing proposal is delivered, hopefully within a week or two we hear back and the decision is made to go forward with the work we recommended. At that point, we may go into a negotiation phase because it’s possible that the building owner wants to do some areas and not others. so we may have to go back and revise some pricing and whatnot.

In the end, we want to give you the best service and the best price for what you want and need. To get to that point, we need to work together with the customer as a team to make sure we have the same end goal.

Price Variables on Roof Repairs

As you can see from the video below, no matter where you are, getting an estimate on a commercial roof repair involves a lot of variables, so it’s not an easy thing to answer straight away over the phone.  But with a bit of information, we’ll do our best to give you an idea of what you’re looking at.


hello there my name is Steven from London flat roofing when I’m answering the phone number off the last how much did the new flat roof cost well the answer to this is really down to a number of factors it’s not an easy one to answer straight away however with certain information I can come up with an approximation of how much a flat roof would cost some of this information that I really need is what is the area of the roof how much difficulty is there involved with the roof what’s access like to it what’s the substrate line.i what is it actually which is on the roof at the moment is it new build is it an old roof is it Asheville all sorts of different questions like that really helped me make my mind up on what I can do for you and how we can reroute that roof for you now do you want to strip the roof or not and that’s an interesting run because today if we strip a roof we actually have to insulate the roof there’s a building regulation part l-1b of the building regulations says but if you strip a roof you must insulate afterwards so if you don’t want to trigger there then we really should be using an overlay system so all this information I can gain from you on the phone once I’ve got that information I can then work out using a meter ridge ray how much the roof is going to cost you so if you take this roof behind me as an example I really need to know the links and the width of the main area so I can calculate this it’s square meter ridge then I need to know the details around the side the flashing details now in this particular roof the roof actually goes up and over the parapet walls so therefore I need to know what area that is and would calculate that slightly different than the main area because the main area we’ve done at one cost that will be done at a slightly greater cost because there’s more effort in doing that and you naturally see the men behind you going around and doing that first that takes a lot more time than it does just laying out the main roof once I’ve got that kind of information I can then work out square meters right and I can give you a proximate price of the roof over the phone my name is Steven from London flat roofing if I can help you my details are on screen now

Roof Repair Or Roof Restoration Systems

This particular blog post Roof Repair Or Roof Restoration Systems had been formerly published on: www.DCRoofingArizona.com

Roof coatings and liquid applied roofing materials are probably the fastest growing segment in the commercial, industrial and flat roofing market today. There’s a reason for that, but what we want to do today is take a look at some of the primary liquid applied roof technologies that are out there, and the differences in some of the physical properties of those.

The four we’re going to look at today are acrylic, silicone, asphalt emulsion, and synthetic rubber. Specifically we’re going to take a look at the puncture resistance differences between those, which is going to be a combination of the elongation and the tensile strength. Let’s have a look at some of these tests that we do and the difference between these products, and why they’re gaining different traction in the market.

roof restoration systems being rolled on

Let’s start with the exciting, fun test first. We coated small watermelons with four commonly used roof restoration products. We let them cure for two weeks, and then drop them from 25 feet.

A bare watermelon, on impact, is obliterated.

Asphalt Emulsion

The first product we tested is a commonly used asphalt emulsion for both roofing and waterproofing. It was applied to the melon at 60 mils or 1.5 millimetres. Unreinforced asphalt emulsion has no elongation or tensile strength, resulting in very poor impact resistance. The watermelon didn’t fare much better than the first one.


Next up is an acrylic roof coating widely used in the industry. Applied to the 3rd melon at over 40 mils, or 1 millimetre. The forces created inside the melon on impact quickly split open the acrylic coating.

Silicone Roof Coating

Third is a very popular silicone roof coating. It was applied to the melon at 50 mils. While silicone has higher tensile strength or tightness than acrylic, the impact test shows how easily silicone tears once a split or tear begins. With both silicone and acrylic you can see that even 100 to 300 percent elongation does not allow for much movement when fully adhered.

Synthetic Rubber

Finally we have synthetic rubber manufactured by Triton, called Tritoflex, applied to the melon at 80 mils, or two millimetres. Not only does the rubber withstand the forces upon impact, it nearly retains its original shape after the melon has broken inside.

Considering the Tritoflex rubber was not damaged, we dropped it a second time this time next to a broken uncoated watermelon for comparison. The properties of over a thousand percent elongation and 600 psi tensile strength, were evident in this demonstration.

Let’s take note of the value of these tests, because you may be thinking these are a little extreme… What kind of roof experiences these kinds of forces? And that’s an appropriate thought. But if you think about, it roofs do experience a lot of extreme forces. They experience hail, foot traffic, dropped tools and equipment, high wind speeds and underlying structural movements.

Though those underlying structural movements may not be big in distance, they can be very big in force. And therefore that’s why it’s important when you’re choosing a roof membrane in your design, that it performs more like a skin and not like a paint.

On to the second test, which is a simple yet effective puncture resistance test to demonstrate the forces required to puncture through a coating or a membrane.

First up asphalt emulsion.

The material has no elongation or strength, resulting in a quick break.

Next acrylic.

This first one is about 40 mils, or one millimetre in thickness, and cured for two weeks. There’s minimal stretch in the force required to cause a puncture was minimal.

This next acrylic is thicker, about 60 mils or 1.5 millimetres in thickness, and cured for two weeks. With the increased thickness, there is minimal increased puncture resistance.

Now we have silicone.

This one is approximately 60 mils in thickness, 1.5 millimetres, and cured for two weeks. You can see the strength is higher than acrylic requiring more force to stretch it over the pipe, but once the silicone breaks it results in a very quick tear through the entire sheet. While the tensile strength is higher than acrylic, the actual tear resistance is poor.

Synthetic rubber membrane called Tritoflex

Last is a synthetic rubber membrane called Tritoflex. This sample is approximately 80 mils, or 2 millimetres in thickness, and cured for 2 weeks. The test shows both the high elongation properties of synthetic rubber combined with the high tensile strength. This requires a much higher force to puncture the membrane.

All right now that we’ve done the test let’s summarize these four product technologies that we showed you, and where they’re most used and some of the differences that are important to know between them.

First we’ll look at cold process asphalt emulsion.

It’s called cold process because it’s applied at room temperature, or ambient temperature, unlike older asphalt technologies and roofing that are heated up in hot kettles and applied at very high temperatures. This is typically a water-based product that’s used often for damp proofing. And in roofing it must be reinforced because you can see here the elongation at break properties and the tensile strength properties, are quite low. And so reinforcement is used in that in order to make it more like a membrane. And so asphalt emulsion is used often as a base layer for a lot of acrylic roof restoration systems. And I have a small sample of some commonly used asphalt emulsion roof coating here, and you can see that the strength, there’s not a whole lot of strength here as our videos demonstrated, but if you reinforce it with a polyester fabric then it it has no elongation or flexibility but now all of a sudden it’s it’s a very tight, stronger membrane.

Now asphalt emulsion is not UV stable, so it needs to be top coated. And there’s a certain window in which it needs to be covered otherwise the UV will damage it. And asphalt emulsion does not do well with freezing temperature. It has terrible freeze-thaw flexibility and a low temperature bend of flexibility in those tests. So it’s commonly used in warmer year-round climates like southern California in the southwestern united states, as part of an acrylic restoration system used to extend the life of a roof. Obviously the cost of an asphalt emulsion product and system is very low, even though it’s applied often at 40 to 100 mils total thickness, including the polyester reinforcement.

So then we moved to acrylic. And acrylic is a very commonly used roof restoration product, has been for decades as a topcoat on spray foam, as a top coat over asphalt emulsion. It’s also used directly on existing roofs to extend the life of that roof. Because acrylic has good reflectivity, so it provides great UV protection to preserve the integrity of the underlying roof components such as the waterproofing membrane, and the insulation. And so acrylics are great for that purpose as sort of a sunscreen to protect the existing roof from UV damage, and to preserve the integrity longer, and protect it from that heat gain and the heat aging.

Acrylic is typically applied at 20 to 30 mils, or sometimes it may be higher. You have to be careful with acrylic going to thick because it is a very permeable product, it will absorb water doesn’t do well under ponding water. It will wrinkle up and it will allow for vapor transmission. It is a breathable product, therefore it’s not used as a waterproofing membrane. It’s used as a uv protection coating. And it’s also a very sustainable, because acrylic can be easily repaired and easily renewed with time. And so by using an acrylic roof coating you can create a sustainable system and continue to preserve the life of that roof, indefinitely, when used properly.

Obviously the properties of acrylic are like a high grade paint. There’s not a lot of stretch, though some roofing acrylics have some good tensile strength, but they can be torn quite easily and there’s not a whole lot of elongation at break there. So you have to think when something is fully adhered to a surface you’re going from absolutely no distance to a far distance when you have that expansion and contraction. Here’s a very thick acrylic which would absorb a lot of water and again not a whole lot of flexibility there. Again, it gets stronger the thicker that you put it on but again the tear resistance on that is is quite poor. But it is inexpensive, so it’s a great way to extend the life of roof when you don’t need a new roof membrane or a new waterproofing layer on the existing roof.

So next we move the silicone

Silicone is also a breathable product, it has a 5 perms rating, but it does hold up well to ponding water. That’s why it’s become popular as an alternative to acrylic, because it does better under ponding. But I put the asterisk there because it’s still a permeable product. If water sits on silicone long enough, it will absorb through, and and can get beneath the silicone film, and so that’s something important to know.

Silicone is also bright white, like acrylic, so it’s good for reflectivity for UV protection, for energy efficiency, but I put an asterisk on there too because silicone is notorious for having a bad dirt pick up compared to acrylic. While acrylic has a good dirt pick up resistance, it stays a white for many years, silicone can tend to yellow and discolor because it has a high dirt pickup. It’s stronger than acrylic, as you can see here, and has a little bit more kind of a stretchiness or rubberiness because silicone is a part of the rubber family, but like I showed in the video that once a tear does start, it peels apart almost like cheese. Almost no pressure at all will cause the silicone to tear. And that’s because of the type of chemical matrix that silicone has. And so that’s something to be leery of in areas where you may have hail, and if you have a split into the silicone, that split can easily tear and continue through the entire roof surface. So that’s something you have to be a concerned with regarding silicone. It’s also very difficult to repair. Silicone has a very low surface energy compared to acrylic, so acrylics will stick to other acrylics quite easily – emergency repair patches, asphalt mastic, rubber mastic, urethanes will stick to acrylic. None of those materials will adhere to silicone because of the low surface energy. Only silicone will adhere to silicone. So it makes it very difficult to repair, very difficult to re-coat, because the right silicone has to be matched up in order to do a re-coat.

Also, with that low surface energy makes it a very slippery product. So if there’s any dew on the surface, any rain on the surface, it can be a big safety hazard. And it’s also not a true waterproofing membrane. Typically it’s only applied 20 to 36 mils dry, but it is an economical choice. The reason why this has become more more popular than acrylic, because of a little bit of that increased tensile strength, but mostly because it holds up better under ponding. But you do have to sacrifice some of that reflectivity with time when you go with the silicone.

And then the fourth liquid applied product that we tested was a synthetic rubber material produced by Triton called Tritoflex. It’s typically applied at 60 to 80 mils dry, it has over a thousand percent elongation at break, with over 700 psi tensile strength. And it’s 0.1 perms, so it’s considered an impermeable or non breathable product. So it is considered a waterproofing membrane.

With the elongation and tensile properties that makes it very durable, and makes it resistant to hail, foot traffic, a lot of different things that a roof does experience including underlying structural movement, if you think of, for example, an existing metal or steel building. It withstands ponding water indefinitely, not just for a certain period of time, like silicone. It is also renewable, both on its own, exposed to UV, because synthetic rubber produced here is a UV resistant product, but when you use the acrylic topcoat you can continue to sustain the life of that roof indefinitely, which is a great savings in value for a building owner long term.

The non breathability can be a pro in a con. It’s good because you know that it’s completely watertight, it’s not going to allow any moisture transmission or air or gas transmission to the underlying roof or structure. But it can be a con in some situations. If they’re if you’re just trying to extend the life of the roof short term, and acrylic may be better because if you have some residual moisture in the roof system and acrylic will allow that breathability. A synthetic rubber membrane will not; it’ll trap any moisture in in an existing surface and will allow that to breathe out.

And it is synthetic rubber is black in color, so that’s a downside. So these are already white, this is black. But again, this is used as a waterproofing membrane for durability, flexibility, to create a long-term 15, 20, 25 year roof system. When combined with an acrylic top coat, you can achieve that reflectivity, the sustainability and then with that sacrificial layer you can continue to renew the life of that roof indefinitely.

And here I have some examples of the synthetic rubber on its own, so you can see here the elongation and recovery, but combined with the tensile strength makes it very difficult to pull apart, but fully adhere to a roof it makes a lot of difference when you have the combination of good flexibility with the tensile strength.

And then of course combining it with a reflective topcoat, you’re able to achieve the goals that you have here, while having a strong durable seamless membrane underneath. As you can see here this is acrylic on top of the rubber, that the acrylic splits apart with any of that stretch. So this would be similar to an acrylic directly on a surface that has some expansion and contraction and movement.

So essentially as you look forward to considering a roof restoration system for your building, you have to take a look at the technologies that are available. The technical data behind those and what’s most appropriate for your roof system. Do you need something that’s going to protect your roof long term? Are you looking for simply uv protection and a short-term extension of life? Or are you looking for a long-term new waterproofing membrane to protect your structure?
