      Why WeatherBlocker Premium Starter Strip Shingles?

      Don’t overlook the importance of pre-cut starter strips in a quality roofing system. WeatherBlocker™ Premium Starter Strip Shingles have factory applied, properly positioned Dura Grip™ Adhesive which helps lock down shingle edges at the eaves and rakes to reduce the risk of shingle blow-offs. They provide about 42% more coverage per bundle than our 3-tab shingles. Plus, they’re compatible with all GAF shingles, ensuring seamless integration. Installers like that the easy-to-use perforated design allows each piece to be separated into half pieces without cutting, creating straighter roof edges.

      WeatherBlocker Premium Starter Strips are a standout.

      Choose WeatherBlocker Premium Starter Strips as part of your GAF roofing system.

      GAF Limited Warranty Options

      Customers tell us the most confusing part of buying a roof is choosing the warranty. So here’s a quick overview of some of the warranties available.

      See pertinent limited warranty for complete coverage and restrictions. Lifetime refers to the length of warranty coverage provided and means as long as the original individual owner(s) of a single-family detached residence [or eligible second owner(s)] owns the property where the qualifying GAF products are installed. For other owners/structures, Lifetime coverage is not applicable. Lifetime coverage on shingles requires use of GAF Lifetime shingles only. Lifetime coverage on shingles and accessories requires use of any GAF Lifetime Shingle and at least 3 qualifying GAF accessories. Visit for qualifying GAF products.

      Step 1

      Separate the strips into half pieces at the perforated line.

      Step 2

      Place at the eaves and rakes, leaving a .25” to .75” overhang, sealant facing up, at the edge.

      Step 3

      Nail about 1.5” - 3” above the starter strip’s edge and put 4 nails into the strip at about 1.5”, 13.5”, 25.5” and 37.5” across the strip.

      Step 4

      Install half pieces vertically up the rake. Overlap the eave edge starter strip at least 3” with the sealant nearest the edge.

      Half Strip

      For shingles with an exposure less than 6” use a half 8.5” strip by tearing on the perforation line.

      Full Strip

      For shingles with an exposure of 6” or greater use a full 17” strip. Do not separate the strips.
