How long does silicone roof coating last? An average of 15 years. That’s 15 years of extending the life of the existing roof while simultaneously protecting it from further damage.
Silicone is a solvent-based sealant, meaning it’s thicker than acrylic and other water-based sealants. With silicone roof coatings, your roof might not need multiple coats to reach the desired level of thickness. It also goes on easier in hot environments, since it doesn’t thin as much as water-based sealants do. Fewer coats + easy application = less work. That’s a win-win.
Liquid silicone coating protects flat roofs from deterioration, but what else does it do? Quite a bit, actually:
Silicone roof coatings are made for metal, single-ply membrane, granulated modified bitumen and sprayed-in-place polyurethane foam roofing. On these roof types, silicone coating creates a seamless membrane that keeps water out. It also prevents damage from ponding water, UV rays and strong winds. These properties make it a great choice for any climate, even those with heavy rain and intense sun exposure.

How long does silicone roof coating last?
When applied correctly, it can last up to 15 years. That’s one of many great features of silicone roof coating — you get significant use out of it. Annual inspections and maintenance will help ensure it lasts as long as possible.
Is silicone roof coating worth it?
Absolutely. Installing silicone roof coating is beneficial to building owners because it introduces features such as durability, flexibility and resistance to ponding water. Silicone is one of the best coating materials available as it doesn’t erode quickly or become brittle.
What is the longest-lasting roof coating?
The longevity of the coating depends on how thick the roofing material is applied. A 30-millimeter thick coating can last 10 years longer than a coating that’s 20 millimeters thick. It may take multiple coats to reach the desired thickness. Refer to our product page to determine the best number of coats for the product you’re using.
