Secondary Water Barrier for the best roofer
A Secondary Water Barrier is a backup system to prevent water intrusion (through the joints in the roof decking) into the home in the event of the primary roof covering and underlayment over a roof being blown off during a hurricane.
Peel and Stick as the underlayment with an asphalt shingle is a great roof system. Secondary Water Resistance, on the wind mitigation form is referring to a second way of preventing water from entering through a roof.
Peal and Seal is a surprisingly lightweight self-adhesive, modified bituminous roofing underlayment. It's reinforced with a heavy weight fiberglass mat for use under tile, slate and asphalt shingles. Glass fiber reinforcement on the upper surface provides enhanced skid resistant properties for a roof.
Peal and Seal is a self-adhesive, modified-bituminous roofing underlayment reinforced with a heavyweight, fiberglass mat for use under asphalt shingles. A split-back release film allows for easy handling and installation. This film peels off to expose the adhesive, which adheres directly to concrete, plywood, wood composition board and gypsum sheathing decks.
