Beyond basic requirements, certification also means we are trained to install a complete GAF roofing system, not just shingles. That includes leak barriers, roof deck protection, proper ventilation, and ridge caps designed to work together as one system. This system‑based approach is what allows GAF to back many of our installations with enhanced warranty coverage that non‑certified roofers cannot offer.

Understanding a Complete GAF Roofing System
A GAF roofing system is more than just shingles. It is a set of engineered components that work together to keep water out, manage attic temperature and moisture, and help your roof last longer. When all of these pieces are installed as a system, you get better performance, fewer problems, and access to stronger warranty options.
GAF Leak Barriers
Leak barriers are self‑adhering membranes installed in high‑risk areas such as eaves, valleys, roof edges, and around roof penetrations. They help seal around nail holes and protect your home from wind‑driven rain and ice dams that can force water back under the shingles. In cold‑weather regions like Northeast Ohio, a quality leak barrier is one of the most important defenses against winter leaks.
GAF Roof Deck Protection
Roof deck protection (underlayment) adds a secondary water‑shedding layer between your shingles and the wood deck. Synthetic roof deck protection is designed to be stronger and more durable than traditional felt, helping your roof dry out more quickly if moisture ever gets underneath the shingles. It also provides a consistent surface for shingles to lie flat, which improves appearance and performance.
GAF Shingles (Primary Roof Covering)
Starter strip shingles are installed along the eaves and sometimes along the rakes before the main shingles go on. They provide a straight, secure edge and include adhesive that helps lock down the first course of shingles. Using true starter strips, instead of cut‑up field shingles, reduces the risk of blow‑offs and helps your roof resist high winds.
GAF Rooftop Accessories
GAF rooftop accessories include items like pipe boots, flashing components, sealants, and other specialized parts that complete the roofing system. Using accessories that are designed to work with the rest of the GAF system reduces weak points and inconsistencies that can lead to leaks. It also helps maintain eligibility for enhanced system warranties, since the roof is built with compatible components from top to bottom.

Using true starter strips, instead of cut‑up field shingles, reduces the risk of blow‑offs and helps your roof resist high winds.
GAF Attic Ventilation
Proper attic ventilation is a critical but often overlooked part of a roofing system. GAF ventilation products combine intake vents at the soffits with exhaust vents at the ridge or high points on the roof. This balanced airflow helps remove heat and moisture from the attic, which can reduce ice dams, minimize the risk of mold and rot, and help shingles last closer to their intended life span. Good ventilation also supports more consistent indoor comfort and can help lower energy costs.
GAF Ridge Cap Shingles
Ridge cap shingles are specialized shingles designed to cover and protect the hips and ridges of your roof. Unlike cutting standard shingles, dedicated ridge caps are pre‑shaped to fit the contour of the roof peaks and include enhanced sealing and impact resistance. They complete the roof’s appearance while sealing some of the most exposed areas against wind and water. When paired with ridge vents, they also help protect the opening where hot air escapes from the attic.
