What Sets Timberline Apart from Basic Shingles

As experienced roofing contractors in East and Middle Tennessee, we have no trouble noticing the differences between quality shingles and less-desirable products. But we understand those differences may not be as obvious to the average homeowner. If you are looking for reasons to invest in GAF Timberline shingles for your upcoming roof installation, the list below will provide some motivation.

• LayerLock Technology: Most asphalt shingles in East and Middle Tennessee are flat products that are glued together with a standard adhesive. Timberline shingles are fused using a proprietary asphalt-to-asphalt bond that allows the shingle to act like a single unit once installed. This leads to better wind performance and little risk of the layers separating over time.
• StrikeZone nailing area: The nailing area on Timberline shingles is significantly wider than the industry standard. This gives roofers a bigger nailing target, leading to nail placement accuracy of up to 99.9 percent. As improper nailing is a major cause of shingle failure in Knoxville, this design feature makes a big difference.
• Impressive wind rating: Most basic shingles carry a wind rating in the 60 to 80 MPH range. That’s really not sufficient for East and Middle Tennessee. GAF Timberline shingles, meanwhile, come with a rating of 130 MPH. That means more peace of mind when a powerful storm blows in.
• Dimensional profile: Standard three-tab shingles are flat and uniform, producing a plain look from street level. Timberline shingles give your roof visual depth in a way that mimics the appearance of natural wood shakes. You’ll love the shadow lines that are created across the roof and the overall premium appearance of the finished installation.
• Trusted roofing brand: GAF is North America’s largest roofing manufacturer, and the Timberline HDZ has been the best-selling shingle in the country for several years. Since you’ll be relying on this product for decades to come, going with the leading product line from a proven brand is a wise choice. And our status as a GAF Master Elite roof means we’ll install the shingles right.

The Local Roofing Problems GAF Timberline Can Address

There are some specific conditions faced by homes in East and Middle Tennessee that pose a challenge for all roofs. Those conditions can include dramatic temperature swings throughout the year, powerful thunderstorms, high winds, and significant humidity. By choosing Timberline, which are some of the best asphalt shingles on the market, you can insulate your home against those weather conditions.

• Algae staining: If you have noticed a pattern of dark streaks on older roofs in Knoxville and Nashville, those streaks are algae stains, not dirt. The high summer humidity in this region leaves your roof moist much of the time, allowing algae to grow under the sun. Timberline HDZ shingles address this problem by using time-release copper to limit growth and keep your roof looking clean.
• Wind and storm exposure: The 130 MPH wind rating that comes with all Timberline HDZ shingles is important in East and Middle Tennessee. Even if winds approaching that speed only happen once a year, you’ll be thankful you invested in such a quality product when that storm does arrive.
• Impact resistance: It’s easy to focus on wind speeds in a storm and the damage that wind can do through uplift. But wind is also a threat when it sends debris flying. With Class 3 impact rating, Timberline shingles have been tested to withstand a 1.75-inch steel ball being dropped from 20 feet without cracking. So, if a branch breaks off a nearby tree and lands on your roof in Lebanon, these shingles keep you and your family safe.
• Heat and UV exposure: Sometimes, the danger posed by Knoxville and Nashville’s weather is as simple as the powerful summer sun. Heat and UV exposure can break down low-quality shingles, leading to premature aging. The fiberglass mat base and ceramic-coated granules of Timberline HDZ shingles are strong enough to take decades of sun exposure.

A Closer Look at Popular Timberline Options

Timberline is a family of shingles offered by GAF. Each product in the lineup is built on the same architectural profile, but there are three tiers available to meet the needs, preferences, and budget of any homeowner in the Knoxville or Nashville area.

Timberline HDZ

GAF Timberline HDZ shingles are the flagship product and the best-selling shingle in the line. It includes a number of features that lead to excellent performance and durability, including the LayerLock Technology and StrikeZone nailing area. It also has the widest color variety of the group.

Timberline UHDZ

The UHDZ line includes many of the same features as seen with the HDZ, but adds extra touches to boost performance even higher. Specifically, there is the UltraMat fiberglass mat technology that takes the shingle up to a Class 4 impact rating. It also uses a Dual Shadow Line to provide an even more three-dimensional appearance than what is available with the HDZ.

Timberline HDZ RS

The difference with the HDZ RS line from the standard HDZ is the reflective nature of the granules that coat the shingle. This model is meant for homeowners who want to optimize for energy efficiency. The HDZ RS will reflect away more solar heat than typical shingles, which can help with cooling costs in Knoxville and Nashville.

The Timberline Warranty is Among the Best in the Business

One of the biggest things to look for when shopping for shingles is warranty coverage. Installing a new roof is a big investment, so you want to know that you’ll be covered in the event that something goes wrong.

Fortunately, GAF offers one of the best warranties in residential roofing with the Timberline product line. Every shingle carries a Lifetime Limited Warranty against manufacturing defects.

Depending on how the roof is installed, you may also benefit from the WindProven Limited Wind Warranty or the StainGuard Plus Algae Protection Limited Warranty.

As you plan your roofing project with Mobley Brothers Roofing and Renovation LLC, be sure to ask about the coverage that you’ll qualify for.

Why Installation Matters As Much as the Material

If you opt for GAF Timberline shingles for your roofing project in East and Middle Tennessee, you’ll be working with a great product. But that isn’t the end of the job. To get the best possible performance out of these materials, you’ll need an experienced installer who will do everything right down to the last detail.

There are many key steps in the roofing installation process, but nailing the shingles to the roof may be the most important of all. Nailing mistakes can lead to shingle failures such as leaks or lost shingles, so getting this point right is critical. Thanks to the wide StrikeZone included in the design of Timberline shingles, installers will have an easy time hitting the mark.
