The Benefits of Silicone Roof Coatings

roof coatingThere are numerous things you can do to prolong the life of a flat roof, and adding a coating is at the top of the list. When properly applied, a roof coating can save your building from leaks, reduce stress on your HVAC system, improve the look of your building and best of all, save you money.

However, not all roof coatings are created equally. Some materials and products perform better than others in terms of durability, longevity and overall effectiveness. And of course, it all depends on how well your roofer applies it.

Here at Pacific West Roofing, we use a silicone coating, or “restoration membrane,” rather than an acrylic coating. We firmly believe in the superiority of this product, and our crew members are trained to apply it in accordance with absolute best practice.

Here are some of the ways silicone coatings outperform others.

It’s More Durable

  • Sun Damage and Bad Weather– Prolonged sun exposure frequently causes acrylic roof coatings to become chalky and discolored or even crack. A silicone membrane, on the other hand, can stand up to the harshest UV rays without degrading, chalking or cracking. This type of coating also resists oxidation, wind-driven sand, hail, and extreme temperatures.
  • Standing Water – Traditional water-based coatings, like acrylics, cure as water evaporates after application. But, should water ever pool up on the roof for two days or more (which can definitely happen around here), the coating will start to return to its liquid state and separate from the roof substrate. Not good. Silicone coatings actually cure and become stronger in reaction to moisture (as long as the substrate was dry, to begin with), further protecting your roof from the effects of standing water.

It’s Eco-Friendly

While the specific silicone coating we use (HSS 535 Solvent-Free Silicone Roof Coating by West Development Group) is available in a variety of appealing colors, the white offering is regarded by the Cool Roof Rating Council for its highly reflective and emissive properties. By essentially shielding your building from the sun’s heat, this silicone coating can reduce energy use by as much as 35 percent. It’s also Energy Star rated and may contribute to LEED credit points.

Additionally, because the product has ultra-low VOCs and is free of hydrocarbon solvents, it’s safer for the environment than other coatings.

It’s Convenient and Easy to Use

This specific silicone product can be used on almost any existing flat roof surface, including smooth Built-Up Roofing, granulated cap sheet, acrylic coating (as long as it’s well-adhered), metal (including sloped metal roofs), concrete, spray-on polyurethane foam, and various aged roofing membranes. The coating can be sprayed or rolled on just one day after a thorough pressure washing, and touched-up with a brush or roller.

Also, because of its high solids content and absence of hydrocarbon solvents, this coating can be applied in excess of 40 mils in a single coat without blistering and still maintain maximum adhesion. This all makes applying the coating very simple and easy for your roofer.

If you’re hoping to avoid a full roof replacement, a silicone restoration membrane may be just what you need to get by. This coating has a 10-year warranty and it’s tax deductible.
