How to Plan a Balanced Attic Ventilation System

Want to save money on your heating and cooling bills and keep your home feeling pleasant year-round, regardless of the weather outside? Opting for an energy-efficient roof might be the way to go.You can replace your existing roof with a new system that uses energy-efficient materials and colors. For instance, while a roof's color may seem like an aesthetic choice, it can play a part in keeping a house cooler in the summer by reflecting sunlight. Meanwhile, the best roofing materials for energy efficiency can help with thermal emittance and keep a house warmer in the winter.Here's a comprehensive overview of energy-efficient roofs, why color and material matter, and why you might consider updating your home's roof.Benefits of Energy-Efficient RoofsAside from offering protection from the outside elements, reducing your home's environmental impact, and enhancing its curb appeal, energy-efficient roofs can offer several benefits. With energy-efficient roofing materials, homeowners may notice cost savings through a reduction in energy consumption, and more interior comfort during particularly hot or cold weather conditions. The lifetime of a roof may even be extended, depending on manufacturer warranties. All of these factors can positively impact the resale value of your home when it's time to sell.Additionally, local laws may require your home to meet certain energy standards, which an energy-efficient roof can help with. For example, due to Title 24, California homes must comply with specific cool roof requirements. GAF shingles like Timberline HDZ® RS Shingles and Timberline® CS Shingles have been rated by the Cool Roof Rating Council (CRRC) for use in Title 24 projects. At GAF, a primary focus is building sustainable products that not only adhere to changing building standards, but also help create a more sustainable future.Most Energy-Efficient Roofing MaterialsGenerally, the most energy-efficient roofing materials are metal, tile, and asphalt. Here's how each of these materials differ.MetalMetal roofs are known for their longevity. Metal is also considered one of the best roofing materials for reflecting sunlight, which results in improved energy efficiency. Its strong insulation properties help keep the interior at a comfortable temperature while keeping out hot (or cold) exterior air. Lastly, metal roofs are environmentally friendly, as most of the material is recyclable.TileCommonly made from clay and slate, tile roofs are another energy-efficient option. Tile roofs are often seen in the Southwest, where daily temperatures can reach triple digits and the sun beats down most of the day. This roofing material sometimes comes preheated to help reduce heat absorption in sunny weather and high-temperature areas. You can also add coatings to the roof to further improve its reflectivity once it's installed.AsphaltWhile asphalt shingles are a popular choice across homes in the United States, they aren't known to have a lot of solar-reflecting ability. That said, many new energy-efficient asphalt shingles are equipped with solar-reflecting granules.For example, GAF Timberline® CS Shingles can help keep your attic cool and allow you to use your home's air conditioning system less. And GAF Timberline HDZ® RS Shingles, which are rated by the Cool Roof Rating Council, come in several light and dark finishes, so you can choose your color scheme. These shingles offer excellent performance and can withstand strong wind speeds, while giving you the same look as traditional asphalt shingles.Best Roof Colors to Reflect HeatLight roof colors tend to reflect more sunlight and heat than darker colors. Popular light colors used for energy-efficient homes are white, light gray, and light brown.White is the most effective roof color to reflect heat. According to the US Department of Energy, a white roof stays coolest because it can reflect anywhere from 60% to 90% of sunlight. Meanwhile, other products typically reflect 30% to 60% of sunlight. Darker colors tend to absorb more heat, with black roofs absorbing the most heat followed by brown and dark gray.Shingles That Reflect Heat Regardless of ColorThough darker colors tend to absorb more heat, you may want a darker roof to match your home's aesthetics. For example, if you want your home's siding to stand out, a dark-colored roof is more favorable than a light one.Today, you don't have to decide between color and energy efficiency: modern shingles, like GAF cool roof shingles, can still reflect heat despite their dark shade. For instance, GAF Timberline HDZ® RS+ Shingles are offered in charcoal, hickory, aged chestnut, and other rich colors while still maintaining their high energy efficiency. You can choose the color that best fits your home's design without having to sacrifice your roof's energy efficiency.When Color May Not Matter as MuchKeep in mind your local weather and your property's features. If your home doesn't get as much sun or is covered in shade by nearby trees, the color of your roof may not matter as much when it comes to solar reflectance.Other Ways to Improve Roof Energy EfficiencyApart from color and roofing material, you can take other steps to improve your roof's energy efficiency.InsulationAttic insulation protects your roof during any season. In the summer, it reduces the transfer of heat coming in from outside. While your roof material is the first line of protection, you can think of insulation as your second line of defense.Insulation also protects your home against humidity and can prevent pests from getting inside your home. During the winter months, attic insulation can also prevent ice dams that can lead to expensive damage.VentilationIf your roof doesn't have proper ventilation, heat will always make its way inside. Proper ventilation allows the warm air inside to constantly shift out through the vents and be replaced with cooler air. Apart from regulating temperatures, it reduces condensation, which can result in mold, and keeps your insulation in good condition. Adding roof and attic vents while ensuring insulation isn't covering any airflow is the best way to ensure good ventilation.Updating Your Roof with Modern MaterialsFor more help navigating the variety of energy-efficient roofing materials available, speak to a local contractor. These professionals can tell you what's most popular in your area and help you understand the advantages you could enjoy after upgrading to a more energy-efficient roof.

As a roofing contractor, keeping yourself and your employees safe is crucial, which involves using the right equipment. Ladder hooks, sometimes referred to as roof hooks, are used to secure a ladder over the top of a roof's ridgeline. They're an essential piece of safety equipment for steep-slope roofing work.How Do Ladder Hooks Work?These hooks resemble a shepherd's crook that hooks over the roof's ridgeline and stays put with an attached T-bar to secure it to the other side of the ridge. The bottom of the crook has a smaller hook that holds the ladder and prevents it from slipping or sliding down the roof. Ladder hooks are typically made from heavy-duty steel and can support several hundred pounds. They essentially turn the ladder into a more stable set of stairs, creating a safer and more efficient work environment for roofing professionals, especially during steep-slope work.Most hooks also feature a rubber wheel that can help you get the ladder safely up onto the roof. Once you secure the hook on the rungs of the ladder, roll the ladder up the slope (on its back). When it passes the roof ridgeline, flip the ladder over to secure the hooks over the top of the ridgeline.Why Should You Use a Ladder Hook?According to the American Ladder Institute, 500,000 people are treated for injuries from using ladders every year, with 300 of those injuries leading to fatalities. With newer home styles featuring more dramatic rooflines with steep pitches, you may find yourself facing 10:12, 12:12, and higher pitches more regularly. Ladder hooks can help make working on these roofs safer.They can provide stability and security on lower-pitched roofs, too. You may also want to use them for performing repairs around skylights or chimneys, especially if the roof surface is icy or slippery. And they can provide secure footing in cases of suspected damage, such as a weak or rotting deck.These safety devices are designed to prevent the ladder from damaging shingles, so there's no downside to using them.Can a Ladder Hook Replace Other Safety Measures?Using a ladder hook can make you feel more secure and stable on a steep pitch. But you shouldn't forego other safety measures, such as using a personal fall arrest system consisting of lifelines, lanyards, and deceleration devices attached to an anchor point and connected to the body harness. Remember, the anchorage should be able to support 5,000 pounds per employee. Ladder hooks are designed to secure the ladder to the rooftop—not to secure a person or prevent them from falling.How Do You Choose the Right Ladder Hook?To find the right ladder hook, contact your ladder's manufacturer to see if it has a hook designed to work with its ladders. If it doesn't offer any, review the ladder hook manufacturer's guidelines to see what types of ladders are best suited for its hook. If your ladders are due for replacement, you can also look for manufacturers that offer kits with both the ladder and the hook.For more learning opportunities and resources to help you succeed in your roofing business, visit the GAF Center for the Advancement of Roofing Excellence (CARE).

For years, replacing your roof meant scheduling an in-home visit with a salesperson, looking at shingle colors on sample boards, and then waiting days or weeks to receive a written quote. But recent advancements in roofing technology have simplified the process for both contractors and homeowners. You can now quickly and easily visualize the design, estimate material costs, and establish a project plan before work begins.Whether you're buying a new roof or simply having it repaired, here are five of the latest advancements in roofing technology that could help your planning process.1. Design ProgramsWhen purchasing a new roof, choosing the color can be one of the hardest parts. The shingles you choose will protect your home for years to come, so you want to ensure the color complements your home and neighborhood. But it can be challenging to imagine what the finished roof will look like.Fortunately, technology has simplified this part of the process. Programs such as GAF Virtual Remodeler allow you to upload a photo of your home (or choose a model home) and virtually try on different colors and styles. You can feel confident about your design decisions before you purchase materials.2. Aerial ImageryContractors can use high-resolution aerial imagery to see a bird's-eye view of your home and assess your roof's current condition, depending on how recent the satellite image is. They can evaluate the roof's health, deem whether certain areas of your surrounding property need to be protected, and note any extra safety precautions that might be necessary for the work.The imagery tool helps speed up the overall process. Contractors don't need to come out to your home to understand the complexity of your roof, and you don't need to make time in your schedule for a site visit.3. Aerial Measurements and Estimating SoftwareGoing a step further, technology companies have combined aerial imagery with other software programs to calculate the measurements of a home's roof. These measurements are then input into estimation programs and used to quickly generate a material estimate for your new roof's installation.This means you can receive your project estimate within hours—not days—and you can be confident in the estimate's accuracy. Once you know the total cost of the materials, you can better plan your budget.4. All-in-One Project PlatformsIn an attempt to provide a high level of customer service and satisfaction, many roofing professionals have been tapping technologies provided by the manufacturers themselves. These all-in-one platforms streamline the roofing sales process, allowing contractors to remotely perform a number of tasks and virtually collaborate with homeowners, while ensuring they are using the most accurate and up-to-date information from the manufacturer.Using these kinds of digital tools, roofing professionals can inspect your home to create estimates. They can then meet with you virtually (or schedule an in-person consultation, if you prefer) to review your project and the related options for your home. You can also sign your contract and easily make your payment electronically.5. Online Shopping ToolsEvery day, millions of homeowners shop online for essential items that get delivered to their doors. Since there's nothing more essential to your home than its roof, why not research and buy yours online?That's exactly what GAF Master Elite Contractor Gunner Roofing owners Andrew and Eddie Prchal had in mind when they developed the Gunner Estimator. The brothers designed the program to enable homeowners to shop online for a roof. With a focus on improving the overall customer experience, the Prchals wanted to take the hassle out of purchasing a roof.
