GAF Warranty

What is Covered/Excluded

This System Plus Limited Warranty covers certain GAF roofing products installed on your roof (the “GAF Products”) including GAF Asphaltic Shingles, GAF Ridge Cap Shingles, GAF Starter Strip Shingles, GAF Leak Barrier Products, GAF Roof Deck Protection Products, GAF Cobra® Attic Ventilation Products, and GAF-labeled Ultimate Pipe Flashing® with EasySleeve (manufactured by Lifetime Tool® & Building Products LLC), in the unlikely event that they contain a manufacturing defect.

Note: This limited warranty does not cover low- slope membranes, Master Flow® Ventilation Products, ShingleMatchTM Roof Accessory Paint, or GAF Cornell Ventilated Nail Base Roof Insulation. Please go to for a copy of the limited warranties covering these products.

How Long Your Warranty Lasts: All GAF Certified Products

Coverage begins when your GAF Products are installed. (If a GAF AuthorizedTM Home Builder initially registers this warranty for a newly constructed home, coverage begins when you take title to the property and you properly transfer coverage.) Coverage for all GAF Products lasts as long as the warranty for manufacturing defects for the type of shingle installed in the field of the roof. Note: If cut-up GAF Strip Shingles are used instead of the eligible GAF Ridge Cap Shingles, the warranty and non-prorated period for the cut-up strip shingles are the same as they would be if those shingles were used in the field of the roof.

Manufacturing Defects: GAF Lifetime Asphaltic Shingles

Subject to the provisions below, all GAF Asphaltic Shingles other than Royal Sovereign® and Marquis WeatherMax® Shingles carry a Lifetime limited warranty (as defined below) against manufacturing defects and a non- prorated period of 50 years.

Definition Of Lifetime Protection Period: 

The word “Lifetime” means as long as you, the original owner(s) [or the second owner(s) if coverage was properly transferred within the first 20 years], own the property where the shingles and/or accessories are installed. The Lifetime warranty term and 50-year non-prorated period are applicable only to shingles and accessories installed on a single-family detached residence owned by individuals. For any other type of owner or building, such as a corporation, governmental entity, religious entity, condominium, or homeowner association, school, apartment building, office building, or multi-use structure, the length of the warranty is 40 years and the non-prorated period is 20 years.

What Is Not Covered

Even if your GAF Products were not properly installed according to GAF’s application instructions or to standard good roofing practices, this limited warranty remains in effect. However, GAF will NOT be liable for and this warranty does NOT apply to:

  1. Damage resulting from anything other than an inherent manufacturing defect in the GAF Products, such as:
    1. improper fastening of your shingles or accessories or application not in strict accordance with GAF’s printed application instructions, if the improper installation was the cause of the damage.
    2. settlement, movement, or defects in the building, walls, foundation, or the roof base over which the shingles or accessories were applied.
    3. inadequate ventilation.
  2. Damage resulting from causes beyond normal wear and tear, such as:
    1. acts of nature, such as hail, fire, or winds (including gusts) over the applicable wind speed listed above.
    2. impact of traffic on the roof or foreign objects, including damage caused by objects blown onto the roof by wind.
    3. improper storage or handling of the GAF Products.
  3. Ice damming, except for leaks in the area of your roof covered by a GAF Leak Barrier which are caused by a manufacturing defect in your GAF Leak Barrier.
  4. Shading or variations in the color of your GAF Products or discoloration or contamination caused by fungus, mold, lichen, algae (except for blue-green algae if your shingles or ridge cap shingles were labeled with the StainGuard PlusTM with Time Release or StainGuard® logos), or other contaminants, including that caused by organic materials on the roof.
  5. Labor costs, except as specifically provided for above, disposal costs, and costs relating to underlayments (unless your claim involves a manufacturing defect in a GAF Underlayment), metal work, and flashings.
  6. Damage to the interior or exterior of the building, including, but not limited to, mold growth.

Effectiveness. This limited warranty will not take effect unless all eligibility requirements have been satisfied, this warranty is registered to you, and your roofing contractor has been paid in full.
