Let’s jump into the Grand Sequoia AS line of asphalt shingles, and take a look at the major benefits, as well as warranties and color options.
The “AS” in these Grand Sequoia shingles stands for Armor Shield, as these shingles deliver extreme impact resistance. In fact, they have received the highest Class 4 impact rating (UL 2218).
To receive this rating a shingle must endure, and pass, impact testing that involves dropping various sized steel balls onto tested materials from different heights before evaluating whether there are any cracks, tears, or fractures on the back surface of the product. One of the reasons this shingle can withstand such rigorous testing is because of its proprietary SBS modified asphalt formula, which delivers rubber-like flexibility and increased impact resistance.
In addition, the GAF Grand Sequoia AS line can be upgraded to a GAF FORTIFIED roofing system. The FORTIFIED program adds an additional layer of strength to GAF’s already tough and durable roofing system. Legacy Exteriors is a GAF Fortified certified service provider, so if you have questions about the FORTIFIED program, feel free to get in touch with us.
ADDITIONAL BENEFITS INCLUDE:
- Beauty that’s affordable: The cost of these good-looking shingles is lower than you might think, especially considering their durability and sophisticated design.
- Speaking of design, artisan-crafted shapes combined with oversized tabs create a distinct, dimensional look.
This product has earned the Good HouseKeeping Seal.- Potential insurance savings: Since Grand Sequoia AS shingles pass the UL 2218 Class 4 Impact-Resistance Test, they may qualify for insurance discounts (depending on your area and insurance policy; check with your insurance agent to see if you qualify).
- Outstanding wind performance: Grand Sequoia AS asphalt shingles meet the Class 4 wind rating from Underwriters Laboratories — which is the highest possible wind rating.
WARRANTIES:
- Lifetime Limited Warranty: Installing Grand Sequoia AS shingles, along with at least 3 qualifying GAF accessories, qualifies homeowners for GAF’s Lifetime Limited Warranty.
- StainGuard Plus Algae Protection Limited Warranty: GAF provides algae resistance on these shingles that is incredibly powerful, allowing us to offer a 25-year Limited Warranty against blue-green algae discoloration on Grand Sequoia AS shingles.
- DuraGrip Adhesive: Protects your roof from winds and wind-driven rain. In addition, when combined with LayerLockTechnology, and a required combination of 4 qualifying GAF accessories, it helps provide the holding power behind the WindProven Limited Wind Warranty.
- SBS-Modified Asphalt: These shingles are made with GAF’s proprietary SBS-modified asphalt formulation, making them strong enough to pass UL’s toughest impact-resistance test of UL 2218, Class 4.
