It's why property owners and managers nationwide trust us to help them make their best roofing choice.

GAF Capabilities & Services

GAF is not only North America's largest roofing manufacturer but also a true provider for commercial roofing system needs. We offer a wide variety of roofing systems as well as all the accessories and support needed to do the job the right way. Property owners/managers can have peace of mind knowing that GAF has the best-quality products and stands behind them with the industry's leading guarantees.

GAF continues to invest in plants that are more environmentally friendly and in products that utilize the latest technologies.


Choosing GAF means not only installing high-performing products from a trusted commercial roofing company but it also means having the ability to protect your roof with great guarantee coverage. GAF offers maintenance and guarantee options that are tailored to your property’s needs.


Regular roof maintenance is a responsibility of ownership and an integral part of extending the life of your building's roof. If you don't perform ongoing roof maintenance, you're putting your property at risk of damage from leaks — not to mention taking the chance that your guarantee coverage will be jeopardized.

The GAF WellRoof® Guarantee Extension1 can help safeguard your property and extend your guarantee by 25% at no cost to you. This incorporates a very extensive annual inspection to review the condition of your roof, performed by a GAF Certified Maintenance Professional (CMP).

Sustainability/Environment/Energy Savings

As the industry leader, GAF is proud to offer a broad array of environmentally friendly solutions. We have options for commercial, healthcare, education, manufacturing, and government properties, including products containing recycled materials, reflective or "cool" roofing, re-cover roofing to reduce landfill waste, garden roofing, and solar roofing products. GAF has also worked to incorporate sustainable practices into the manufacturing process, including the recycling of shingle waste at our plants and a Zero-Waste-to-Landfill effort. Plus, our Certified Green Roofer™ Program recognizes professional roofing contractors for their recycling efforts!
