Timberline Ultra HDZ: How It Measures Up to Other GAF Shingles

The newest line of reflective asphalt shingles designed by GAF, the Timberline HDZ® Reflector Series, can give your home both enhanced protection from the elements, and curb appeal.The roofing shingles, available in stylish dark colors, create an attractive aesthetic that can be used to comply with certain code requirements for reflectivity. This is particularly important in California, where state building codes like Title 24 and local regulations like the Los Angeles County Green Building Code require specific roof reflectivity to help conserve energy.Here's what you need to know about these new reflective shingles, including their unique technology, and potential for providing savings on energy costs.Reflector Series Shingle FeaturesTimberline HDZ® RS shingles have several strengths that make them stand out from the competition. By design, the roofing shingle's features enhance reflectivity, and provide additional protection against algae and wind.EcoDark® GranulesTimberline HDZ® RS shingles feature EcoDark® granules, a newly formulated technology that provides deep, rich, dark colors while maintaining reflectivity. Available colors include Charcoal—currently the darkest highly reflective shingle color available in California—and several other color blends, each providing a full, dimensional look.LayerLock® TechnologyTraditional asphalt shingles have multiple layers of material connected with adhesive or mechanical fasteners. With GAF LayerLock® Technology, shingle layers are mechanically attached. This provides additional protection against wind, which can lift loose shingles off the roof.Thanks to the technology, GAF can lay claim to another industry first: offering a warranty, with no maximum wind speed limitation**.4 Benefits of Reflector Series Shingles for HomeownersTimberline HDZ® RS shingles give you several benefits.1. Code Compliance and Cooling Cost ReductionIn California, RS shingles can be used to meet the solar reflectance requirements for steep-slope residential buildings as mandated in 2022 Title 24, Part 6, of the California Code of Regulations and the Green Building Standards Code of Los Angeles County. Both codes set a minimum reflectance rating, called the solar reflective index (SRI), which measures a material's ability to reflect heat and sunlight. The lower the SRI value (from 0 to 100), the hotter a material becomes in sunlight. The higher the value, the cooler the material becomes.Shingles with a higher SRI, like GAF Timberline HDZ® RS shingles, reflect more sunlight, helping to lower temperatures inside and reduce the energy—and costs—required to cool your home.2. Rich, Dark Colors to Match Any Style or AestheticYou no longer have to compromise between choosing deep, rich, dark colors, popular in today's architecture, and meeting reflectivity requirements. In addition to providing the darkest high-reflectivity color, Charcoal, the other colors in the line feature GAF High Definition® color blends that give the reflector series shingles a dimensional, wood-shake look.3. Protection Against Blue-Green AlgaeStains from blue-green algae, a cyanobacterium called Gloeocapsa magma, can reduce your home's value. Timberline HDZ® RS shingles feature GAF Time-Release Algae-Fighting Technology, which uses specially engineered capsules infused with thousands of copper microsites. The copper releases steadily over time, preventing algae growth for many years. With this technology, GAF offers a 25-Year StainGuard Plus™ Algae Protection Limited Warranty*, which is especially beneficial in hot, humid, and coastal climates like California.4. A Wind Warranty with No Maximum Wind Speed LimitWhen installed with the required number of GAF roof system accessories, the Timberline HDZ® Reflector Series shingles' LayerLock® technology allows GAF to offer a 15-Year WindProven™ Limited Wind Warranty** with no maximum wind speed limitation.A Stylish Choice for California HomeownersIf you live in California, GAF Timberline HDZ® RS shingles are a smart option for meeting the state's strict reflectivity requirements while matching the aesthetics and styles of today's architecture. The shingles' features give your home added protection and can reduce cooling costs, potentially putting money back in your pocket.Ready to get these benefits for your roof?

Each year, hurricanes cause billions of dollars in losses for homeowners across the country. In an effort to combat this, the roofing industry has made advances to help reduce the impact caused by storm damage, including specially designed shingles that can handle heavy impacts and high winds.If you live in a hurricane-prone area, here's what you need to know about hurricane shingles designed to handle the high wind speeds and debris impacts that can come with major hurricanes.Understanding Impact-Resistant ShinglesHurricane Shingles, (or impact-resistant shingles) are built to withstand both impacts and high wind speeds. They're robust, often created from a unique combination of styrene-butadiene-styrene (SBS) and asphalt, providing more strength than non-reinforced asphalt shingles.In hurricane-prone areas, sharp winds can easily blow debris and other large objects—like tree branches—onto a roof. Shingles that pass the UL 2218 Class 4 impact-resistant test are most effective at limiting impact damage. These shingles are tested by dropping a 2-inch steel ball from 20 feet above. The steel ball impacts various target locations of the shingles on the test deck. The test includes two impacts per target location. The shingles must handle the impact while showing no evidence of ruptures or cracks through the shingle.These shingles should also be able to withstand Category 3 hurricane wind speeds, ranging from 111 to 129 mph.Choosing the Right Shingles for Your RoofWhen deciding between hurricane shingles, consider their wind classification, impact resistance, and warranties.Wind ClassificationQuality, UL 2218 Class 4 impact-resistant shingles should be able to handle at least 110 mph wind speeds. These shingles tend to be made of either metal or asphalt mixed with SBS. For example, the GAF TimberSteel™ Premium Metal Roofing System is effective against high wind speeds due to layers of protection, innovatively designed to help protect your home against the elements.Impact ResistanceQuality hurricane roofing materials, including impact-resistant shingles come with enhanced protection against impacts from objects, especially hail. While these shingles may be more expensive than non-reinforced asphalt shingles, they tend to require less maintenance. And since these shingles can withstand certain kinds of impacts that often happen during a hurricane, it may not need as many repairs.WarrantiesConsider the shingles' warranties and what you're protected against. A wind warranty can guarantee roof repair and replacement for specific wind speeds as long as you meet all the warranty's requirements.GAF Hurricane Roofing InnovationsCertain GAF shingles like Timberline® AS II have the best possible wind and impact resistance ratings. They meet the highest rating, Class F, for the Standard Test Method for Wind Resistance of Steep Slope Roofing Products (ASTM D3161). This means they can withstand wind speeds up to 110 mph.Timberline® AS II shingles also have the highest rating, Class H, for the Classification for the Standard Test Method for Wind Resistance of Asphalt Shingles (ASTM D7158). This means the shingles can resist uplift from up to 150 mph wind speeds. If that wasn't enough, these shingles' Class 4 classification for the UL 2218 test means they can handle a 2-inch steel ball drop test from 20 feet above.With the highest possible ratings for all these tests, the Timberline® AS II shingles are proven and tested against the closest possible hurricane-like conditions (testing performed under controlled laboratory conditions). The robust SBS-modified asphalt material and LayerLock® technology help fortify your roof against wind, rain, and hail. These GAF shingles are also eligible for the WindProven™ Limited Wind Warranty**, which provides infinite wind speed protection when installed with the required combination of four qualifying GAF accessories.Shingle Installation and Roof Maintenance TipsProperly installing impact-resistant shingles is essential for them to perform their best, so choose an experienced roofer. They'll know how to nail the shingles correctly and make sure they're firmly attached to each other and the roof to prevent any openings for leaks or weaknesses. Also, ask your roofer if they know how to install hurricane clips to help prevent your roof from flying off during a storm.Once your roof is installed, perform regular maintenance every year before and after hurricane season. Replace any missing or broken shingles, and secure any loose shingles. Also, replace any rusted nails or flashing. As part of roof maintenance, confirm your gutters are working properly and clean out any leaves, allowing water to flow away from your home.A weak point on a roof can degrade even further in harsh hurricane weather, and ensuring your roof is in stable condition can help keep you and your home safe.FAQsWhat are the best shingles for high wind?The best shingles for high winds are classified as Class F for the ASTM D3161 and Class H for the ASTM D7158 test. These two classifications mean the shingles have the best ratings for handling hurricane winds.Do impact-resistant shingles last longer?Due to their durable construction, made with SBS-modified asphalt, which makes shingles more flexible and better able to withstand impact stress than standard architectural shingles, GAF impact-resistant shingles are built to last many years.Preparing for the Next StormAfter the hurricane season, check your roof for damage. View this GAF guide on roof storm damage to learn what to look for and what to expect for possible repairs. If your roof needs work before or after a storm, reach out to a certified contractor* in your local area for guidance and support.*Contractors enrolled in GAF certification programs are not employees or agents of GAF, and GAF does not control or otherwise supervise these independent businesses.

If you have trees on your property, you're probably aware of their many benefits. They can boost your property's aesthetic appeal, create privacy, and provide shade to keep your home cooler. Trees can also protect your roof from ultraviolet rays and block wind, minimizing related damage.However, if trees aren't maintained, they can cause damage to your roof. Here are the signs to look for, what to do if a tree falls on your roof, and how to prevent tree damage to your roof in the future.How Nearby Trees Can Damage Your RoofYou're likely aware that the worst damage to a roof can occur when an entire tree falls on your home. This can happen during a severe storm or if an older tree is ill or damaged.However, one tree branch can cause plenty of structural damage, too. Even a small branch falling on or rubbing against your roof can scratch or dent its protective layers, especially if it's laden with snow or ice.And branches aren't the only culprits that can damage your roof. Fallen leaves, nuts, and needles from trees can accumulate, blocking your gutters and roof valleys. This creates an environment that absorbs moisture, leading to moss or mold growth—both of which can reduce your roof's lifespan. Ponding water from this debris can cause leaks over time.Overhanging branches can also create too much shade, exacerbating any moisture issues by making it challenging for your roof to dry. Additionally, branches that touch your roof create easy access for squirrels and other animals, potentially leading to intrusions and damaged roofing components.Signs of Roof DamageTo stop any issues from a tree over the roof from worsening, watch out for signs of roof damage. While a professional inspection can help pinpoint problems by taking a closer look at your roof, you can also perform an inspection from the ground.Look for any cracked, broken, scratched, or curled shingles. Also, note any missing shingles, especially after a windstorm. Check for moss, mold, or an accumulation of debris like leaves and needles. All of these issues can lead to leaks or larger problems down the road, such as structural damage.What to Do If a Tree Falls on Your RoofIf a large branch or entire tree has fallen and damaged your roof or siding, prioritize your safety. If you see any live wires, smell gas, or spot major water leaks, call your utility company right away to shut off your service. Evacuate everyone from your home, and call your insurance company. In most cases, the company will send a professional roofer to evaluate the damage.While you're waiting for the expert to arrive, document the damage by taking photos and video of any areas the fallen tree affected. Once the insurance company has approved your claim, hire a professional to remove the tree and repair the damage.While most homeowners insurance policies cover roof repairs from tree damage, your insurance company might deny your claim if it discovers you failed to do preventive maintenance.How to Prevent Tree Damage to Your RoofProactively addressing tree-related challenges can help you minimize potential roof damage, saving you time and money in the long run.Clear DebrisRemove leaves, twigs, needles, and nuts from your roof and gutters. Installing gutter guards can also help prevent debris from clogging them.Trim BranchesTrim any tree branches that are too close to your roof. Avoid having any part of a tree over the roof—there should be at least 6 feet between your roof and the tips of a tree's branches. If you can't safely trim branches yourself, hire a tree expert.Remove Dangerous TreesIf an arborist determines that more than one-quarter of a tree's limbs need pruning, you might have to cut down the tree before it can fall on your roof. Don't forget to check with local authorities regarding bylaws and protected tree species.Plant Trees at a Safe DistanceIf you're planting new trees, remember they'll grow large over time. So, select species appropriate for your property's size, and plant them about 20 to 30 feet away from your home.Prepare for the Next Storm with Expert HelpAs the saying goes, the best defense is a good offense. Before another storm can threaten the health of your home's roof, take proactive measures to prevent as much damage as possible.For more information about preventing tree damage to your roof, check out GAF storm and hurricane roofing resources.
