Protecting Your Roof With Reflective Coatings

The drying effects of the sun — due to heat and UV rays — bake out the oils in asphalt, resulting in brittleness, cracks, and loss of granules, which can cause roof leaks. Metal can rust and corrode, and over time, asphalt-based plastic cement used to seal around pipes, vents, flashings, and other roof penetrations, will deteriorate and cause leaks.

You can usually coat roofs up to 10 years old, but older roofs may be too dry and brittle to be effectively coated. If in doubt, consult a professional roofing contractor. Periodic roof maintenance can double the life of your roof and can help to prevent roof leaks in the future.
