Roof coatings are a great idea, IF your roof is a good candidate to receive a coating. There are a few things that have to be inspected and verified before committing to installing and warranting a roof coating system. Just to name a couple of the issues we have to inspect and verify, is that your current existing roof system is capable of receiving and bonding properly to a freshly installed roof coating. Also, we have to ensure that your roof’s substrate is not holding moisture. These are just a few things that must be verified before we can begin to recommend a roof coating as a solution to your commercial or flat roof needs.

The simple answer is that, coating over a shingle roofing system is a bad idea. Shingles are typically installed on sloped roofs, meaning that this system is now designed to shed water. Because shingles are overlapped at installation (by design), they do allow what is called capillary action. This is where water finds it way underneath the shingle. Because of the roofs sloped design, gravity helps pull that water down and ultimately off of your roof. If you coat the shingles with any roof coating at all, you may seal any openings or gaps in the field, but there will still be potential access points such as area requiring flashing, where water can get in. So, you essentially are trapping any moisture that makes it’s way underneath the coating, ultimately guaranteeing that you will have deck rot and leaking. The last thing we want to mention is that by coating a shingle roof, you are lowering the permeability of the roof. Basically, you are taking away your roof’s ability to allow vapor to escape your home.

Absolutely. As briefly mentioned above, roof coatings cannot be installed over a wet substrate. You should also know that any acrylic based elastomeric coatings CANNOT be applied to any silicon based roof surface. If the presence of roof blisters are found, we recommend replacing the area(s) where blistering was found and then coating.

Roof coating systems typically last 10-20 years, but in many cases have lasted much longer. It needs be said that a proper preparation of your roof has to be conducted as well as ensuring that you are using a full COATING SYSTEM instead of just applying a coating over your existing roof. Proper installation will also be vital to your roof coating systems longevity and performance. If everything was done properly and to manufacturer specifications, your roof coating system can simply be recoated at the end of the warranty cycle to begin a new warranty period.

Many people will tell you roof coatings will be roughly $1- $4 per square foot to properly install a roof coating system. We have yet to see that come to fruition. That’s probably because we actually use a complete roof coatings system. We do not cut corners to land a job. We would rather walk away from your job than offer you a product that has a greater chance of failure and or poor performance. With a true roof coating system, we are seeing prices range from $4 – $7 per square foot and even then, it depends on the product requirements, protrusions, obstacles and difficulty that your roof presents.
