    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 roof maintenance on an ongoing basis, you're putting your property at risk of damage from leaks — not to mention taking the chance that your guarantee coverage will be jeopardized.

    GAF's WellRoof® Guarantee Extension can help safeguard your property. This incorporates a very extensive annual inspection to review the condition of your roof, performed by a GAF Certified Maintenance Professional (CMP).

    GAF CMPs will perform the following vital services for your roof:

    • Conduct a yearly inspection
    • Communicate the roof's needs to you
    • Make maintenance repairs as necessary
    • Provide documentation to you that the repairs have been made
