Roof Coatings

Roof coatings provide 100% waterproof and high UV reflectivity for reduced indoor temperatures. They are excellent for flat roofs as they can even withstand unlimited ponding water and work great under solar.

Overview

In the beginning, all the roofs we did were hot asphalt. They were smelly and very unpleasant to install. Worst of all they cracked after about 10 years and you needed to haul them down to the dump. No matter what kind of flat roof you have — Brai, capsheet or pitch & gravel — we firmly believe your best choice is to coat it with a 96% silicone coating.

LeakMaster's Opinion

For decades roofers in Hawaii have tried to find a long term solution to ponding water on flat roofs.  Standing water, which creates mold and fungus growth, will break down the best of the traditional systems and force you reroof after 10 years or so.  

For commercial roofs we are long time applicators of Duro-Last Single Ply roofing.  It’s track record in Hawaii, when Leakmaster installs it, is 100% effective.

For homeowners a 96% solid Silicone roofs is just as good when applied correctly.

No matter what system you choose for your flat roof, we would avoid any asphalt system as they don’t last in our hot Hawaiian sun.

Pros & Cons
Pros
  • 96% Silicones are cool, clean and long lasting with material warranties up to 50 years.

  • Duro-Last Single ply is custom cut to your commercial roof, like a tailored suit, and is billed as “The Worlds Best Roof.”  We have never had a major problem with any that we have put down in the last 10 years plus.

  • Silicone manufacturer’s have warranties that range from 20 to 50 years. So far all the 96% solid Silicones we have tested all appear to be very good–and very similar to each other.

Cons
  • Asphalt roofs, like Brai cap sheet, Alumination, pitch and gravel, etc are all dinosaurs.  They do, however, serve as a great base for applying silicones over.

  • Solvent based Silicones, such as GacoRoof, are long lasting but will not clean off easily

What to know about Flat Roofs.

Traditional Flat Roofing Services

LeakMaster is a leader in switching flat roofs from the dreaded old hot tar kettle to the “torch welded” membrane, known as Brai. Today, few roofs are the old torch welded because of insurance regulations. The movement has been towards “self adhered” membranes, also referred to as “peel and stick. LeakMaster goes a step further and reinforces all seams since they have a tendency to unravel with time.

For commercial roofing we also install Duro-Last which is a prefabricated single-ply roofing system ideal for virtually any commercial or industrial, flat or low-sloped application. Extremely durable and easily installed without disruption to daily operations.

Flat Roof Repairs

If you are experiencing leaks, LeakMaster will find the source. Sometimes even using high tech equipment to pinpoint the source. We can install a quick fix for a short term solution and recommend some long term solutions like new roofs and coatings.

Most flat roofs leak from the seams, laps and transitions. For flat roofs we normally reinforce these areas and install roof coatings. We can coat a roof only on problem areas or do the entire roof.

We won’t sell you a new roof if all you need is a simple repair.

Flat Roof Coatings

Coatings have become ultra sophisticated and a great addition to flat roofs. We can even coat old existing hot asphalt roofs. There are many options for coating materials depending on your needs.

Choices run from high solids silicones, such as, Cool Roof Store Silicone to NXT Silicone or GacoRoof Silicone. There are also other economical options if there is no need for ponding water protection, such as, acrylic coatings: NXT Cool Zone or Cool Roof Store Ceramic.
