Advantages of GAF Roofing

When debating whether GAF is suitable for you, consider these advantages, in addition to our product overviews above, to make a final decision.

GAF Complete Roofing system

A significant advantage is the GAF-Lifetime Roofing System, which consists of six GAF roofing products to give your roof full protection. When you choose the GAF complete roofing system, you get:

  1.  GAF Timberline Shingles (limited lifetime warranty)
  2. Cobra ridge vent and attic ventilation
  3. Roof deck paper by Deck Armor
  4. Starter strip shingles (necessary at the eaves, optional for the rakes)
  5. Weather Watch leak barrier for valleys
  6. Ridge cap shingles (non-vented ridges and attic vents)

Your roofer must use GAF shingles and at least three other GAF products to qualify for enhanced warranties, including any of these listed.

Certified Installation

GAF doesn’t just make great products, but they also use experienced roofers who have received training on installing GAF products correctly. The GAF Master Elite certification gives peace of mind that the roofer meets the following qualifications:

  • Insured and licensed
  • Good craft reputation
  • Receives ongoing professional training on the installation of GAF roofing

If you choose not to use a GAF Master Elite contractor, you will not be eligible for the enhanced warranties, including System Plus or Golden Pledge. See our warranty section for more on this.

Superior Warranties

Since we’re on the topic of warranties, we want to list in the advantages section that GAF has some of the best warranties in the industry compared to competitors like Owens Corning or CertainTeed. 

Plenty of options

No matter your budget, preferred styles, special features (impact resistant, wind resistant), or location, GAF is sure to have a product that meets your individual needs. 

Disadvantages of GAF

Compared to other roofing brands, there aren’t that many downsides.

Shortage of Master Elite roofers

You may find problems reaching a Master Elite certified roofer that’s received GAF training and certification. If you’re not interested in enhanced warranties, this issue won’t affect you. But remember that GAF requires a Master Elite roofer to install your roofing if you want advanced protection. Currently, only 2% to 3% of roofers have the desired qualifications and training.


When the layers of dimensional shingles start to separate, delamination can occur as a defect due to improper fusing of the layers during manufacturing. In most cases, this issue occurred while the warranty was still under 100% coverage. Delamination can occur with any brand of architectural shingles, so we’re not just picking on GAF.

Warranty loopholes

Unfortunately, this area is a problem spot for many GAF customers. However, 90% of all GAF customers experienced zero issues with their roof, eliminating the need to test the warranty policies. This percentage is similar to that of Owens Corning or CertainTeed. If you have to file a claim, it can be a huge hassle, with multiple interactions while you have to “prove” the problem exists and is the responsibility of GAF to fix.

Pricing by GAF Products

In terms of pricing, GAF’s amounts are fair compared to the competition. Below, we list the prices for each product line’s materials (per square or 100 sq ft) and the price with installation.

Timberline NS (Architectural)

Pro Tip: The cost per square (100 sq ft) does not include the cost of starter shingles, trim, flashing, hip and ridge caps, underlayment, or supplies (nails, tarps, etc.).

Did You Know: Fiberglass shingles come in bundles (1 bundle = 33.3 square feet), so the price may be based on the price of a bundle rather than the price per square. Most shingles require three bundles for one square (100 square feet).

GAF Warranties

As we stated earlier, GAF is at the top of the pack in terms of warranties. However, it would be best if you took the time to read all the fine print listed in warranties before choosing a product line. There are five warranties GAF offers, with differing terms for all shingles except 3-tab:

  • Limited Warranty Shingles & Accessories 
  • Limited Warranty Roofing System 
  • System Plus 
  • Silver Pledge 
  • Golden Pledge 

Tip 1: What is the rule on warranties?

A lifetime warranty will last for however long the original buyer owns their house. If a new owner buys the house, this person will qualify if the transfer happened during the Smart Choice Protection Period, which we’ll look at momentarily. However, if the shingles go on anything other than a single-family detached home, the warranty will only be valid for 40 years.  

The limited lifetime warranty has a one-time transfer to new owners, who must provide a written notice to GAF within one year of obtaining the property for the transfer to be valid. Transfers that occur during the Smart Choice Protection Period get the same coverage as the original owner. If the period has ended, the warranty will only last two years past transfer to the second owner.

Tip 2: What is Smart Choice Protection Period?

Costs covered during the Smart Choice Protection Period include labor for repairs or recoveries of defective GAF products and the price for replacement parts (based on GAF’s decisions). The warranty does not cover the cost of tear-offs or roof disposal. Once this coverage ends, GAF will not cover the costs of labor. They only provide replacement parts or reimbursement, based on how long it’s been since the roof was installed divided by the time left under warranty.

Tip 3: What is the Wind Warranty Coverage Term?

The wind warranty only applies if your shingles were installed to GAF’s specific requirements and will not cover damage to starter strip shingles, including replacement and hand sealing unsealed pieces. This warranty reimburses the homeowner for costs of damaged or blown-off shingles. But does not cover flashing, metalwork, or underlayment.

Pro Tip: Your claim will be denied if damage occurs because the roof does not seal properly due to installation at the wrong time of year. Wait until late spring to summer when there is adequate solar heat. If you decide to have your roof installed when it’s cold, ask about hand sealing, which is time-consuming and additional costs.

The warranty will cover the max wind speeds with particular installation when there are six nails per shingle instead of four (LayerLock shingles only need 4 when using GAF Starter Strips on rakes and eaves). You also have to use GAF Starter Strip products for the warranty to cover max wind. When using GAF Ridge Cap shingles, the guarantee only applies if the installation was done to GAF standards.

Tip 4: Is there Algae Warranty Coverage?

The Algae Warranty applies to all GAF products featuring the StainGuard (or Plus) logo, which guarantees that your roof will not become discolored by blue-green algae during the protection period.
