GAF Timberline HDZ® Reflector Series Shingles come in rich, vibrant colors, giving homeowners attractive color options that can be used to comply with the Cool Roof Requirements of Title 24 and the LA County Green Building Standards Code.*Here's why you may want to add these shingles to your business offerings, especially if you work in California.Timberline HDZ® RS ShinglesA few features make these shingles stand out.Meeting California Code ComplianceIn California, residential roofs must meet solar reflectance requirements because they are mandated by California's Building Energy Efficiency Standards Title 24, Part 6 and Los Angeles County Green Building Code. Both codes set a minimum reflectance rating known as the solar reflective index (SRI), which measures a material's ability to reflect sunlight and heat. The lower the SRI value (from 0 to 100), the hotter a material becomes in sunlight. The higher the value, the cooler the material. Shingles with a higher SRI help reduce temperatures by reflecting sunlight which can help reduce the cooling load.The new Timberline HDZ® RS Shingles provide solar reflectance that complies with both Title 24 and the Los Angeles County Green Building Code.Title 24California's Title 24 covers the entire state, unless local requirements are stricter, providing cool roof requirements for residential and commercial buildings based on their locations within 16 climate zones. For residential buildings (new construction), climate zones 1 through 9 and 16 have no cool roof requirements. Climate zones 4, and 8 through 15 require cool roofs for new and reroof applications when more than 50% of the roof is removed.If shingles don't meet the required SRI, alternative paths to compliance include using a radiant barrier, airspace, or additional attic insulation.Los Angeles County Green Building CodeThe Los Angeles County Green Building Code's Cool Roof Ordinance covers buildings in the county and prescribes SRI values depending on the type of building (low-rise residential, high-rise residential and hotels/motels, and nonresidential) and roof slope. High-slope (more than 2:12), low-rise residential roofs must have an SRI of 20 or more. Exceptions apply to roof repairs or replacements where less than 50% of the roof is removed, additions of less than 500 square feet or less than 50% of the total roof area, and green roofs.Selling Points for California HomeownersWhen working with property owners in California and Los Angeles County, you can highlight the following selling points of Timberline HDZ® Reflector Series Shingles.Potential Savings on Cooling CostsReflective roofing may help decrease a roof's temperature and cooling load, which has the potential to lower cooling costs.****StyleTimberline HDZ® RS Shingles provide the darkest highly-reflective shingle available, Charcoal, thanks to EcoDark® granules.

The Role of Roofing Codes and Standards in Roof Venting Product Development

When developing a new roofing product, it's important to ensure it meets the local roofing codes and requirements in multiple jurisdictions. These standards are often regionally similar, but some may require additional testing or the use of certain raw materials. The product development team at GAF works hard to ensure products meet some of the strictest codes, so they can provide years of protection no matter where they're installed.Jeremiah Hershberger, GAF product manager of residential accessories, recently discussed the role codes and standards play in residential roofing product development, specifically concerning roof vent code requirements.Why Are Product Codes and Standards Important?The main purpose of building codes and standards is to maintain public health, safety, and welfare in all structures. They do this by ensuring that buildings are constructed in such a way as to minimize potential hazards, like fire, structural failure, or storm damage.Building codes exist to improve the safety and livability of buildings. They set minimum requirements for the materials and systems installed, as well as their installation methods. In the US, building codes are upheld and enforced by state, county, and city governments through the permitting and inspection processes.Standards also provide minimum design and performance metrics for products and systems. However, unlike local building codes, they are often universally upheld (nationally or worldwide). Organizations like ASTM International and the National Fire Protection Association are responsible for creating, updating, and communicating these standards. Local building codes often use these standards to set minimums for product and installation quality.How Do Roofing Codes and Standards Affect Product Development?"The goal of product development at GAF is to provide enhanced value for our customers and contractors," Hershberger explains. Ultimately, customers need to be confident in the performance of GAF products and building codes and standards provide a minimum threshold for product performance. Accordingly, they must be taken into consideration when designing products.Codes are prescriptive performance requirements for buildings. They include both the materials used to construct the building and how they're installed. All products used in a particular building must meet the local code requirements for that county or city.Standards are used as bases of comparison. Types of standards include:Testing standards that define methods and minimum acceptable resultsRating standards that provide a way to fairly compare productsDesign standards that set the criteria for specific roof system designsWhen products are developed for use in many geographic areas, they must meet several locations' requirements. For instance, when developing a new off-ridge ventilation product, GAF considers not only how much net free area (NFA) the unit will have, but also the performance characteristics required to meet Florida Building Code, Texas Department of Insurance (TDI), and Miami-Dade standards so the product can be used in areas that adhere to those codes.Why Does GAF Pay Attention to Codes and Requirements?"We want our customers to be confident in the performance of our products not based solely on our word but also on the basis of third-party standards that level set the industry," notes Hershberger. "Codes and testing requirements provide customers with that outside assurance that our products will hold up to the environmental rigors of a specific region or location."For example, TAS-100(A) tests a product's performance in wind-driven rain. The test provides information on how well a ventilation product will perform in such an environment and helps the product development team learn how likely it is that a ventilation product might leak, so we can then mitigate that risk.How Do Codes Affect Product Quality?Codes may specify what raw materials can be used to make a product or how it will perform in certain standardized tests. For instance, ASTM E108 or ANSI/UL790 Class A roofing fire ratings require a high degree of fire protection to the roof deck, which directly affect the materials used to produce these products. Similarly, the UL 2218 Class 4 impact test or the ASTM E330 Uplift Pressure Test show how a product performs under naturally occurring forces (e.g., hail or wind)"GAF strives to find the balance between performance, strength, and ease of installation (or handleability)," Hershberger says. "This often leads us to develop products that use higher grade materials (better performance over time), are simpler to manufacture with fewer points of potential failure, and are easier to install correctly (ensuring repeatability)."How Codes Affect the Development of High-Quality Roof VentsCreating high-quality roof vents and rooftop accessories didn't occur by accident. The GAF development team focuses on roofing codes and requirements through an intentional design process to drive innovation. From product ideation to design, development, and launch, the team ensures products meet or exceed several codes and standards, including:Florida Building CodeSets minimum performance standards for roof construction, such as wind resistance, fire performance, and roof ventilation requirements. Products must be approved by the state before being installed.Miami-Dade CountyThis county in Florida has some of the strictest building codes in the country due to its classification as a High-Velocity Hurricane Zone. Products used there must also be approved by the county as meeting not only Florida Building Code, but the stricter county requirements.Texas Department of Insurance (TDI)Regulates insurance companies and the insurance/claims process in the state of Texas. Roofing products are evaluated based on TDI-adopted building specifications regarding products used and installation methods.Other tests performed to ensure product performance include:TAS-100(A). Determines the water infiltration resistance of a ridge area ventilation system (ridge vents, static vents, turbines, or powered vents).Simulated snow/ice dam. Ice dams can form when a roof is not properly ventilated, leading to snow melting and refreezing along the lower edge of the roof.UL2218 Class 4 impact test. The UL2218 test is a steel ball drop test that evaluates the impact resistance of roof coverings. Class 4 products are shown to withstand the 20-ft drop of a 2-inch diameter steel ball without cracking through significant damage.Ensuring Roofing Products Are Up to the TaskThe product team at GAF routinely performs these tests to ensure roofing materials meet local roofing code requirements. The company then makes the results publicly available, helping customers nationwide rest assured that they can rely on GAF roofing products to perform as expected.For more information on the GAF ventilation products that meet or exceed code requirements, explore the ridge and off-ridge ventilation offerings.

When Is the Best Time to Replace a Roof?

If every day was sunny, mild, and a pleasant 75 degrees, there'd be little reason to wonder about the best time to replace a roof. Of course, not everyone lives in areas with ideal weather conditions, as climates vary greatly across the country.So if a client ever asks, "When is the best time to replace a roof?" your answer will likely vary based on where they live and what each season is like. However, you can share some general pointers in response. Here's what to consider for each season to help answer the question, "when is the best time to replace a roof?"SpringSpringtime is traditionally recognized as the kickoff of roofing season, as outside temperatures begin to warm and activity increases. Thanks to melting ice and snow, it's also the time of year that homeowners may want to have their roofs checked out for damage.While spring offers outdoor temperatures that are more friendly for workers, the season also typically comes with an increased chance of severe thunderstorms (and potentially tornados, depending on the region). Spring is usually a good time to schedule a roof replacement if you just monitor the weather forecast for major events to help reduce the chance of delays.SummerWith spring showers in the rearview, most areas of the country see longer stretches of nice weather during summertime, which lends itself well to working outside. Accordingly, summer tends to be the most ideal time for installing a new roof.But with potentially hot days, when is the best time to replace a roof in the summer? Workers will need to start as early in the day as possible because temperatures are usually cooler in the morning. Depending on the forecast temperatures, the job may need to be spread over a few days, so most of the work can be done in the morning hours before it gets too hot. It's also wise to remind customers that workers will need to have breaks in the shade and access to water to stay hydrated.FallThe autumn months can be an equally good time for a roof replacement as summer, as the hot and hazy days have passed, and severe weather isn't as common. The only exception to this is if you're working in an area prone to hurricanes. Hurricane season runs through the end of November and can cause project delays.In addition to the favorable weather, fall is a popular season for roof replacement because many property owners want to fortify their homes and buildings with a new roof before the winter months.WinterIn some areas of the country, it may be possible to continue roofing installations year-round, including during the winter. In southern regions, for example, roofing replacements can often be completed in the winter, as there's less chance of inclement weather. Temperatures may drop, but not as drastically as in areas that see ice and snow more regularly. Of course, it's still important to reference the relevant local forecast when scheduling upcoming work.Sustained stretches of very cold weather does not constitute suitable weather for the installation of asphalt shingles. All self-sealing shingles must be exposed to warm, sunny conditions for several days before they completely seal. Before sealing occurs, shingles are vulnerable to blow-offs and wind damage. Shingles installed in fall or winter may not seal until the following spring. Shingles that are not exposed to direct sunlight, adequate surface temperatures, or that are not fastened or installed properly may never seal. Failures to seal, blow-offs, and wind damage under these circumstances result from the nature of self-sealing shingles, and are not covered under most manufacturer's warranties. Be sure to follow the manufacturer's instructions for proper installation. While most provide guidance about cold weather installations, it will ultimately be up to you to exercise discretion about when to move forward with an installation vs. postponing the work until more favorable weather conditions are present.Other Factors That May Affect Project TimingWhile weather is likely the leading factor that can disrupt scheduled roofing work, if you want to best answer your client's question of "when is the best time to replace a roof?" you'll need to take other factors into account when setting timeline expectations for property owners. One such consideration is the lead time needed for materials. If your customer chooses an uncommon color or a specialty product, it may take longer for materials to arrive.Another factor to weigh is your own backlog. If your production calendar is booked weeks out, clearly communicate the timing to your customers with the knowledge that weather events could impact the schedule. Regularly communicating with customers and setting accurate expectations are key to a positive experience.Looking to learn more roofing best practices and further expand your knowledge base?

Life After COVID-19: How to Resume Your Business and Safely Get Back to Work

Many states are beginning to fully or partially reopen after COVID-19 brought the economy to a halt. However, if you're ready to get back to work and begin serving customers again, there are several guidelines you need to consider to keep yourself, your employees, and your customers safe.Here are some suggestions for how to resume business as safely and productively as possible:Reconnect with Customers and ProspectsOne of the first things you can do to restart your business is reach out to former leads who put their projects on hold during the pandemic.Many customers may still be hesitant about moving forward, but you can try to reassure them by sharing your company's COVID-19 safety policies. Detail the strategies you'll follow to limit face-to-face interactions and potential exposure, such as handling all customer communications virtually.You can also incentivize prospects by offering a special for new customers, such as a discount for certain types of projects. It might feel challenging to offer discounts if your company lost business during the shutdown, but providing some type of customer incentive could help to fill up your sales pipeline.For previous buyers, you may want to consider adding a service and maintenance division or begin selling other verticals such as gutters, windows and siding to re-engage satisfied customers who have already experienced your work.Prioritize ProjectsSince construction is considered an essential business in many states, you may have continued working on certain roofing projects during the shutdown. However, now that the economy is beginning to reopen, you may have customers anxious to get started on projects they had put on hold—on top of the urgent repairs or replacements you already had in the pipeline.Consider several approaches to prioritizing new or backlogged projects. First, you could prioritize customers' needs based on project requirements and deadlines. For example, if a homeowner has had major roof damage and needs to be back in their home by a certain date, you might want to start on that project first.The project's budget is also an important consideration, especially if cash flow is an issue for your business. If a customer has a large project with a big budget, it may be good to get started on that project sooner rather than later.In addition, staffing and resources might dictate which projects you can tackle. You may have had employees who fell sick and are recovering or employees who have moved onto other jobs after work slowed down at your company. Limited manpower could prevent you from taking on certain projects right away, so you may have to focus on smaller or fewer roofing jobs to start. Consider all these factors when you're deciding which projects to prioritize.Keep Employees and Customers SafeEmployee and customer safety are two of the biggest considerations to think through when it comes to resuming work after COVID-19.Many states have provided safety guidelines for the construction industry, including ensuring employees at job sites wash their hands for at least 20 seconds with soap and water, or use hand sanitizer with at least 60% ethanol or 70% isopropanol before leaving the site if handwashing isn't possible.You should make sure employees practice social distancing both inside the office and on job sites. When and where it makes sense, you may want to allow employees to work from home. Paperwork and phone calls can all be handled virtually, so there's not a strong a need for administrative staff to be in the office all the time.On job sites, workers should always wear masks and avoid handshaking and close personal contact as much as possible. They also should limit face-to-face meetings with customers and instead opt for virtual meetings using applications like Facetime, Google Hangouts, Skype, or Zoom. GAF offers several digital tools, like GAF QuickMeasure and GAF e360, to help you remotely take measurements and build 3D renderings from smartphone photos. Use these tools to your advantage to maintain employee and customer safety.Getting Back to BusinessEven though states are beginning to reopen, the health risks of COVID-19 haven't disappeared. It's more important than ever that your business takes steps to protect employees and customers, even while you try to deliver the best service possible.If you are ready to get back to work, visit your state or local health department's website for more specific guidance about how to safely resume business operations. Using these resources can put you in the best position to safely and successfully run your business during this challenging time and help your company adjust to this new normal.
