A polyurethane foam roof coating can extend the life of your roof by 10 years or more.Sprayed Polyurethane Foam deteriorates quickly when exposed to the sun's UV-rays. It needs to be coated with a UV protective coating immediately after installation. Elastomeric roof coatings are the roofing material of choice for this application.
Typically, polyurethane foam roofs have 1-2 inches of foam sprayed over an existing roof such as metal, built up or modified bitumen. It is then topcoated with an elastomeric roof coating to provide a watertight, UV protective membrane.
Polyurethane foam must be recoated every 10 years or so as a preventive measure.
Polyurethane Foam Roof Restoration Process
Cleaning and Surface Preparation
The entire polyurethane roof was thoroughly washed using a 3,000 psi pressure washer. A biodegradeable degreaser was used to ensure a clean surface. All seams, flashings and penetrations were carefully sealed to render the roof watertight.
Priming ensures a good adhesion between the polyurethane foam roof surface and the
At least 30 dry mils of elastomeric roof coating is applied on the entire polyurethane foam roof in 2 coats.
