GAF Master Flow™ Ventilation

GAF Master Flow™ ventilation helps protect the attic by reducing heat and moisture buildup that can lead to damage. It can also support energy efficiency in the summer by easing the workload on your air conditioner while helping reduce the potential for ice dams in the winter. A balanced GAF Master Flow™ ventilation system keeps ridge exhaust from exceeding the amount of soffit intake.

Resources & Tips to Do It Right

Live, Work and Play Under a GAF Roof

Whether you’re installing a new roof system on your home or replacing or restoring a flat roof on a garage or small business, you can feel confident in choosing durable products from GAF. We offer a variety of roof colors and styles for homes, churches and other buildings with sloped roofs, including Timberline HDZ shingles, Timberline Natural Shadow shingles and Royal Sovereign 3-tab roof shingles.

Shingle style isn’t the only thing to consider when it comes to roofing projects. Performance matters, too. Cobra Attic Ventilation products, including Cobra Snow Country roof ridge vents, Cobra Exhaust ridge vents and Rigid Vent 3 exhaust vents, effectively reduce heat and moisture buildup. For building full roof systems, you’ll want to start with Pro-Start starter strip shingles, which are designed to help keep shingles from blowing off. WeatherWatch Leak Barrier and FeltBuster High-Traction Synthetic Roofing Felt aid against damage from wind-driven rain, ice dams and other potential leak sources.

Top off your roof project and protect the roof from leaks in its most vulnerable areas with TimberTex hip and ridge cap shingles or Seal-A-Ridge hip and ridge cap shingles. Working on a flat roof? Tri-Ply is a modified bitumen roofing solution that perfect for the job. If you’re looking for convenience, consider the Liberty Roll Roofing System. With its efficient peel-and-stick application, you can experience hassle-free installation that’s built to last. No matter what type of roof you’re working on, you can find the GAF products you need to create dependable shelter at Lowe’s.
