For many homeowners, protecting their home from roof to foundation is a top priority, especially if they live in storm prone areas. Customers in need of a new roof are making an investment that will impact their home and their families. As a roofing contractor, your customers are trusting you to help them make the best choice. As a contractor in a hail region, you want to consistently help your customers choose the shingle that addresses ALL their personal concerns, including impact, wind and algae.

GAF's Timberline® AS II impact resistant shingles are a smart option for you to offer to your customers. These shingles have all the wind and algae protection of Timberline® HDZ, but they're built for areas where precipitation leaves bruises. They have a UL 2218 Class 4 impact-resistance rating, meaning that they had no visible damage or cracks when a two-inch steel ball was dropped on it twice from a height of 20 feet. UL 2218 Class 4 is the highest impact-resistance rating available, making Timberline® AS II shingles a smart choice for homes located in areas prone to hail and severe weather*.

The Timberline® AS II shingle is flexible and durable as a result of being manufactured with GAF's proprietary SBS polymer-modified asphalt formulation. The polymers result in the shingle having a more rubber-like feel that helps to reduce stress on the shingle when hail hits it.

Same Easy-To-Install Process

Timberline® AS II shingles feature the same LayerLock™ Technology as Timberline HDZ® shingles, which means that installers have a wider nailing zone for ease of installation. In our test, the StrikeZone™ nailing area was found to help an installer fasten the shingles 30% faster than our traditional Timberline® HD shingle with a smaller nailing target.

Since the layers are mechanically attached together during the manufacturing process, you only need four nails (unless local codes require more). Crews can work more efficiently without jeopardizing quality.

Unsurpassed Protection and Style

In addition to providing a UL 2218 Class 4 impact resistance rating, these shingles deliver other powerful benefits. Here are some key points to share with your customers about why the Timberline® AS II shingles are the right choice to protect their home.

  • Style. Timberline® AS II shingles provide an aesthetically pleasing finished roof. GAF's proprietary shadow bands are applied using computerized technology, resulting in a beautiful shingle with unmatched depth and dimension. This adds to the curb appeal of the home and can help increase the resale value.
  • Potential Insurance Cost Savings. Some insurance companies offer homeowners discounts on their insurance policies when they choose UL 2218 Class 4 impact-resistance rated shingles. Encourage homeowners to contact their insurance company to find whether they may be eligible for a discount.
  • Algae resistance. The Timberline® AS II shingle features GAF's Time-Release Algae-Fighting Technology. It allows GAF to offer a 25-year StainGuard Plus™ Algae Protection Limited Warranty** against blue-green algae discoloration.
  • Warranty protection. Because Timberline® AS II shingles feature LayerLock™ Technology, the shingle is eligible for the WindProven Limited Wind Warranty***, the first wind warranty with no maximum wind speed limitation when installed with the required combination of four GAF accessories.

The Smart Choice

As severe weather becomes more common throughout the country, you can be confident that you are recommending the toughest shingle that GAF offers.

In addition to giving your customers peace of mind, you'll also be enhancing the curb appeal and beauty of their home, leaving them highly satisfied with the finished result. For more information on Timberline® AS II shingles, contact your local Territory Manager.

As the winter season approaches, decorating your home with lights is a classic way to show your holiday spirit.

Architects strive to achieve a roof design that strikes a delicate balance between aesthetics and performance. Achieving high-performance means incorporating the code, warranty, and guarantee requirements that building owners must meet — among the most important factors of any construction project — into design vision. This isn't made any easier by the sheer number of roofing systems available. Even experienced architects can find it challenging to get familiar with all available components and positively identify which materials are going to deliver the ultimate protection for the building.
As Erasmo "Mitos" Fuentes — GAF CARE Team Training Lead and highly respected "Maestro" of the roofing world — will warn rookies, errors during installation can have consequences later on in the life of the roofing system. Many are minor, like small leaks. Others, though, can be much more serious, such as major (and potentially catastrophic) cracks.
A harsh storm can cause all kinds of damage to your home, especially its roof. While some roof problems are obviously visible, others aren't as simple to spot. Whether you can see them or not, fixing any issues that pop up in the aftermath of a storm helps keep your home safe from further harm. With strong storms come sharp winds, hail, and heavy rain that can damage shingles, gutters, flashing, and other areas.
