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