Starter strip shingles are used to seal the first row of perimeter shingles and prevent wind uplift. When starter strip shingles are omitted or not installed correctly strong winds have an opportunity to lift the first row of shingles and cause the “domino effect”. This has led to entire roofs being blown off during hurricanes. The photos show where starter strip shingles were not installed correctly on this roof. Proper sealant was not installed. As a temporary measure the first row can be lifted and sealed. When it comes time to replace your roof make sure your contractor uses specially designed starter-strip shingles to keep your roof’s guarantee and prevent system blow-off.
