Roof coating is a practical and cost-effective way to preserve an existing flat roof and get more years out of it. In today’s post, local roofing contractor The Great American Roofing Company examines the conditions that make roof coating a sensible option.
What Is Roof Coating?
Roof coating is a fluid coating that’s installed over an existing roof and forms a durable protective barrier after curing. While it can be applied over roofing systems of any age, roof coating is ideal for use on roofs that have been in use for some time. They provide the following benefits:
Extend the Roof’s Life Span — When properly installed, roof coatings can protect the roof from most weather conditions, including impact from hail and airborne debris. Roof coatings have enough flexibility that protects the outer roof against punctures and minimize the chances of having a damaged roof.
Protection Against Ponding Water — Roof coatings add a waterproof barrier that dramatically slows down the effects of ponding water. While it’s not completely impenetrable, roof coatings will give you more time to address the problem and have your roofing contractor perform repairs in time.
Improves Reflectivity — Roof coatings come in white or a light-colored outer surface, which helps make the roof more reflective. A reflective roof absorbs less heat from the sun and helps reduce the building’s indoor cooling requirements, resulting in energy savings and improved indoor comfort.
Are Roof Coatings Right for Your Commercial Roof?
Before you schedule a roof coating appointment, you have to make sure your roof is in the right condition. This means structural issues such as moisture-damaged substrate, signs of mold damage, and depressions where ponding water can form need to be addressed first. Otherwise, these problems will be sealed under the roof coating.
Another thing that you should consider is the roof’s age. Flat roofs are expected to last 10 to 15 years with proper care and maintenance. Roof coatings often do not make sense if installed on a roof that’s well beyond its expected life span. If you’re unsure whether your roof is suitable for roof coating, schedule an inspection with your roofing contractor.
