Understanding GAF Underlayment Options
High-quality deck protection products such as Deck-Armor™, Tiger Paw™, and Shingle-Mate® are essential for effective roof protection. These products allow moisture to escape while providing excellent defense against wind-driven rain. Good Roofing Company LLC in Lee’s Summit, MO, discusses the key aspects of GAF roofing underlayment.
Importance of Deck Protection
- Waterproofing Layer: Deck protectors serve as critical waterproofing layers over the exposed deck. It’s crucial to avoid non-breathable felts made of polyethylene, as they may trap moisture.
- Local Codes Compliance: Contractors must adhere to local codes when installing deck protection, especially in high-wind areas. Proper installation ensures short-term water resistance and protects roofing materials from harmful substances in the wooden deck.
Installing GAF Roof Underlayment
- Application Process: Begin by rolling out the underlayment. For decks with a 4:1 slope, apply one layer of deck protector. For low-slope applications, install the GAF underlayment half-lapped up the entire roof slope for enhanced water resistance.
- Overlap Techniques: Ensure ends are overlapped by at least six inches to prevent water seepage. Keep end laps at least six feet away from adjacent courses’ end laps.
- Penetration Areas: At areas such as rakes, sidewalls, hips, and ridges, install deck protection before the leak barrier. Lap deck protection over hips and ridges by at least six inches and secure it with enough fasteners to keep it in place.
