Experts recommend that they should be inspected twice a year, Spring and Fall. If any significant weather event occurs, an inspection afterward is recommended. When re-coating is needed, they can apply a new layer of coating right over the existing roofing after it has been cleaned.
- Seamless & Waterproof –When commercial roofing leaks, it typically is in the seams and penetrations. Foam roofing removes this susceptibility because it is applied in liquid, filling in cracks, gaps, and seams in the existing roof.

This reduces the possibility of cracks and splitting.

With less existing roof removal, there is less waste in the environment. The materials used for foam roofing are environmentally friendly, which are Zero Ozone Depleting, Low in the Emission of Volatile Organic Compounds, Free from Chlorofluorocarbons, and Ultra-Low Global Warming Potential.
How do you maintain a foam roof?
Five years after being installed, a re-coating is recommended. If a foam roof looks good without re-coating, it still needs to be re-coated to keep it in top condition. The longer you wait in between re-coating, the more costly it will be, so maintain that every 5-year re-coating schedule to keep your foam roofing looking good. Re-coating foam roofing costs approximately 25% of the original installation. With proper maintenance and routine re-coating, foam roofing will last 25 years.
No flat foam roofing will go undamaged, you can’t stop the environment from causing small holes happening. Maintenance and repair crews walking on the roof can damage it. If you find larger cracks or holes during a regular inspection, schedule a re-coating. Foam roof cleaning can be cleaned by spraying or sweeping it off. Regular cleaning, inspection, and maintenance will increase the longevity of foam roofing.

- Locate the penetration and confirm that the roof foam is dry.
- Sweep or vacuum the roof surface to remove contaminates.
- Using a foam roofing sealant, patch any problem area. This patch can last as long as 35 years.
