Silicone Roof Coatings
Why Silicone Roof Coatings?
Cosmetic roof coatings are possibly the hottest chemistry kind at the roof recovery business and for good reason! They create a fantastic remedy to revive and protect a huge array of commercial roofing substrates including metal, modified bitumen, single-ply, EPDM, TPO, built-up roofs, concrete roofs, along with spray polyurethane foam.
If it comes to deciding on the best silicone roof coat, there are a number of important elements to remember. Below carefully analyze some noteworthy silicone roof coating advantages and disadvantages.
Advantages
- Resistance To Ponding Water; Possibly the best advantage of a silicone roof coating is its immunity to ponding water. Silicone coatings may withstand the harmful effects of ponding water without even breaking down since they are a moisture-cure material, meaning that they won't absorb any extra water after healing.
- Protection From UV; Silicone roof coatings may reflect around 80-90percent of the sun's damaging UV rays. This implies facility managers and land owners can save thousands of dollars by cutting on their centre's cooling costs through the hot summer months and lessening the HVAC system workloads. They erode considerably slower compared to other elastomeric coatings without getting too delicate or difficult. Minimizing the sun's effect on the roof surface not only will help maintain lower energy prices , but in addition, it reduces internal construction temperatures and prolongs roofing lifetime.
- Environmental Reasons: While all silicone coatings are regarded as environmentally friendly, high-solids formulations, especially, are the very best in this respect. Nearly all of the current high-solids silicone coatings are solvent-free and feature exceptionally low volatile organic chemicals (VOCs). Most also meet and surpass all of state-regulated material security criteria, meaning they're secure to be used in all 50 states.
- Weatherability; Silicone roof coatings produce an extremely flexible, monolithic, and impermeable membrane capable of withstanding wind-driven sand, oxidation, and extreme temperatures. They're also able to survive the normal expansion and contraction (thermal motion ) that happens in large roof constructions.
Disadvantages
- Dirt Accumulation; As time passes, this accumulation of dust and dirt around the roof surface induces the system to gradually lose its reflective properties. This slow build-up makes the roofing more prone to heat from sunlight, which negatively affects cooling expenses and inner construction temperatures. We advocate pressure washing a silicone coating system 6-12 months after it has been set up to get rid of any dirt accumulation. This generally eliminates the issue of dirt accumulation altogether. If requested, many contractors will assemble this extra step to the range of work of the proposition.
- Difficult To Spray; Just like with almost any solvent-based coating, silicone roof coatings can be hard on hydraulic spray equipment. In the event the application equipment isn't properly cleaned and preserved, difficulties during the setup procedure are more likely to happen
