How to Install Roofing Shingles Faster with a Larger Nailing Area

The size of the nail zone is an important feature of a roofing shingle. If it's too narrow and nails are not placed correctly in that space, the shingles could delaminate and leaks can occur. From leaks and wind damage to warranty issues, the list of potential problems is long.

A large nailing area can make shingles easier and quicker to install while also increasing nail placement accuracy to help secure them better to the roof structure. That's why GAF's Timberline® Shingles with LayerLock™ Technology* were designed with the StrikeZone™ Nailing Area, the industry's largest nail zone.

Here's a look at how this technology might benefit your business.

Why a Larger Nailing Area Matters

The issues caused by misplaced nails could be significant. A nail placed too low on a standard shingle—called a shiner—could be visible and susceptible to rust. This could allow water to get to the roof deck, causing potential rot and other damage. If a nail is placed too high on a standard shingle, it may not hit the common bond and the shingle may delaminate. This could allow water or wind to play havoc with your roofing project, leading to lost time or expensive callbacks.

Timberline® Shingles with LayerLock™ Technology and the StrikeZone™ Nailing Area minimize these issues by providing a nailing target that is 1.81" wide. The industry's largest nailing area, it's 600% larger than standard Timberline® HD Shingles. This makes it easier for installers to properly hit the zone.

Install Shingles Faster and More Accurately

While there's a learning curve for using any new product, Timberline® Shingles with the StrikeZone™ Nailing Area are designed to be quick and easy to use. These shingles have LayerLock™ technology, which mechanically fuses the two layers of the laminate shingle together, according to Dan Witte, Senior Product Manager at GAF. This allows for an oversized nailing area because the nail no longer has to penetrate the common bond of the shingle in most applications.**


In a test performed at Home Innovations Research Lab, an independent lab in Maryland, a contractor installed Timberline® HD Shingles and Timberline® HDZ Shingles on a sixteen square roof deck using the standard four nail installation. With the increased size and visibility of the nailing area, workers were able to fasten the Timberline® HDZ Shingles 30% faster than the standard ones, and their nail placement accuracy was 99.9%. This is a significant improvement over the 55% nailing accuracy achieved with the standard shingles.

The test confirmed what GAF had surmised: a larger nailing area provides increased nailing speed and improved accuracy in nail placement. These benefits ultimately help installers save time and reduce issues caused by misplaced nails.

Stronger Sealing and Wind Resistance

Besides the improved accuracy and faster nailing speeds, Timberline® Shingles with LayerLock™ Technology also provide a smooth mico granule surface for the sealant to contact. GAF's proprietary Dura Grip™ sealant pairs with the smooth micro granule surface of the StrikeZone™ nailing area for fast tack. Then, an asphalt-to-asphalt monolithic bond cures for durability, strength, and exceptional wind uplift performance. When installed with the required combination of four qualifying GAF accessories, Timberline® Shingles with LayerLock™ Technology are eligible for the WindProven™ limited wind warranty, the industry's first wind warranty with no maximum wind speed limitation.

Other Benefits

The new shingles can be installed using the same materials, equipment, and tools as Timberline® HD Shingles, so you could get on with your job without any major new investments or retrainings.

With their excellent performance and increased nailing speed and accuracy, Timberline® Shingles with LayerLock™ Technology offer unique value to you and your customers.

Choosing the Right Roofing Materials for Your House

Most roofs occupy 40% of a home's visual exterior, so it makes sense that you'd want roofing materials that look good!But there's more to deciding on a type of roofing material than color and design. Your regional climate, local building and fire codes, and budget all matter. Plus, your home construction factors into whether slate tile, clay tiles, asphalt shingles, metal roofing, or another roofing material might be best.Here, we dive into four of the most common roofing materials to help you make the best choice possible.Asphalt ShinglesAsphalt is the most popular roofing material in the U.S. In fact, four out of five homeowners choose asphalt shingles. Most asphalt shingles are made from a fiberglass base that's been soaked in asphalt and coated with mineral granules to create a durable roof covering.There are two categories of asphalt shingles: traditional 3-tab shingles, which are more affordable and built from a single layer, and laminate or architectural shingles, which can be two or three layers. 3-tab shingles are used due to their affordability, but laminate or architectural shingles are more popular due to their durability and greater range of design options.Here's when to consider asphalt:You have architectural roof details with tricky flashing needs.You want distinctive color options and a variety of designs that can match the style and aesthetics of your home.You prioritize ease and speed of install.You want the wood shingle look with high fire and wind resistance.

In addition, when installed with the required combination of 4 qualifying GAF Accessories, it qualifies for the WindProven™ limited wind warranty*, the industry's first wind warranty with no maximum wind speed limitation.SlateSlate has a distinctive look that's often associated with high-end architecture and traditional Northeastern homes. Slate is metamorphic rock that's mined and cleaved into thin sheets for roofing. It's typically dark gray, but may be found in other colors depending on where it was mined.There are three quality ratings for natural slate roofing—S1, S2, and S3. An S1 rating offers the highest resistance to water absorption and weathering, as well as the highest break strength.Slate tile is attractive and offers natural durability. Here's when to consider slate:You want the natural insulation that slate providesYou love the look and the durability of an S1-rated slate tile like GAF Slateline®Your home construction can support the weight of a slate roofYou want the natural durability that slate offers against the elementsMetalMetal roofs come in a range of prices and types. Metal roofs can impart a modern, clean look when done in stainless steel, or lend a period aesthetic when done in copper. You can choose between metal shingles or standing seam metal roofing.Popular metals include galvanized steel, aluminum, copper, zinc, and stainless steel. The metal you choose impacts your roof's strength and durability. It's important to note that some metal materials can dent easily from weather events such as hail.

Clay tiles come in a range of colors and designs. Although they are traditionally handmade, most clay tiles are now machine-made.Concrete tiles replicate the look of clay and typically cost less than clay. Clay roofs are hardy and durable, but they can become brittle over time and break more easily than some other roofing materials.

Architectural shingles mimic the look of slate or cedar shakes.

What Are Architectural Shingles?

If you're a homeowner researching new roofing options, you may be seeing a lot of information on architectural shingles as a popular choice for roof replacements. So, what are architectural shingles? Let's dive in to learn all about architectural shingles and why they are growing in popularity. Types of Asphalt Shingles There are many different types of roof shingles to choose from when it comes to replacing your roof. From three-tab shingles, which are one of the most economical choices, to architectural shingles to luxury designer styles, plenty of options exist for you to choose from. Architectural shingles are also known as dimensional or laminated shingles. They are made up of multiple layers of asphalt-coated fiberglass that are laminated together, giving them their dimensional appearance. What Is the Purpose of Architectural Shingles? The purpose of any roof shingle is to help protect your home from the elements. It's an added bonus if the shingle also delivers an aesthetic appeal that adds to the style of the home. This is one of the reasons behind the development of architectural shingles. They were introduced to the market in the 1970s and '80s to give homeowners a roof that created an architectural interest for the home and could also provide the higher-end look of genuine slate or natural cedar shakes without the added weight, costs, and maintenance. How Do Architectural Shingles Differ from Standard Shingles? The three-tab shingle is made of a single layer of asphalt-coated fiberglass and cut into three equal tabs. It's lightweight, easy to install, and provides a flat, even appearance on the roof. Architectural shingles differ from the three-tab ones in that they are made with multiple layers of fiberglass mat. It's what gives them their dimension and aesthetic appeal. The multiple layers of asphalt-coated fiberglass are laminated together, making it more dimensional than three-tab shingles. Some architectural shingles may be covered by better warranties than three-tab shingles. GAF Timberline® HDZ™ is an architectural shingle that, when installed with the required combination of GAF accessories is eligible for the WindProvenTM Limited Wind Warranty* with no maximum wind speed limitation. Should You Consider Architectural Shingles? Now that we've answered the question "What are architectural shingles?" it's time to consider whether they are the right choice for your home. Many factors go into what type of shingle to choose for your home, starting with your own personal style. Your budget and warranty expectations may also play a role as well as how long you plan to stay in your home. Architectural shingles are a popular type of asphalt shingles that offer homeowners an affordable option to help protect their home from the elements while also delivering style. They are available in a variety of color options that will complement just about every home. It may help to check out what types of roofing styles and colors other homes in your neighborhood have. This might spark inspiration for what you want for your own home. You can also "try on" new architectural shingles virtually through the GAF visualizer tool. Choose a house style that is similar to yours or upload a photo or your home to envision the various colors and style your own look. Once you find a look that appeals to you, connect with a GAF-certified contractor** who can install your new architectural shingle roof. *15-year WindProven™ limited wind warranty on Timberline HDZ® Shingles requires the use of GAF starter strips, roof deck protection, ridge cap shingles, and leak barrier or attic ventilation.
