Shingle Degranulation Can Cause Your Roof To Leak
Two weeks ago we featured the first blog in a series about evaluating your roofs health. We focused on missing shingles and shingle blow off. This week we would like to focus on a less obvious but just as serious issue called degranulation.
Degranulation of a roofing shingle is the process of the colored granules that are embedded into the asphalt beginning to fall out. The granules provide waterproofing and in some cases have a special copper coating that help to prevent algae from thriving on your roof. When your roof suffers a significant amount of granule loss your in danger of major roof leak.
