What Is Roof Underlayment?

La línea más nueva de tejas asfálticas reflectantes diseñadas por GAF, Timberline HDZ® Reflector Series, puede brindarle a su hogar más protección contra la intemperie y un atractivo aspecto exterior.Las tejas para techado, disponibles en elegantes colores oscuros, crean una estética atractiva que puede usarse para cumplir con ciertos requisitos de códigos relacionados con la reflectancia. Esto es particularmente importante en California, donde los códigos edilicios estatales, como el Título 24, y las normativas locales, como el Código Edilicio Ecológico del condado de Los Ángeles, requieren una reflectancia específica en los techos para ayudar a conservar energía.A continuación le mostramos lo que debe saber sobre estas nuevas tejas reflectantes, incluida su tecnología exclusiva y el potencial para permitir ahorros en costos de energía.Características de las tejas Reflector SeriesLas tejas Timberline HDZ® RS tienen varios puntos fuertes que les permiten destacarse respecto de la competencia. Gracias a su diseño, las características de las tejas de techado mejoran la reflectancia y ofrecen protección adicional contra las algas y el viento.Gránulos EcoDark®Las tejas Timberline HDZ® RS cuentan con gránulos EcoDark®, una tecnología con una nueva fórmula que ofrece colores oscuros ricos y profundos sin perder reflectancia. Entre los colores disponibles se incluye carbón, que actualmente es el color más oscuro con alta reflectancia en California, y varias otras combinaciones, cada una con un aspecto completo y dimensional.Tecnología LayerLock®Las tejas asfálticas tradicionales tienen varias capas de material conectado con adhesivo o fijadores mecánicos. Con la tecnología GAF LayerLock®, las capas de tejas se fijan mecánicamente. Esto ofrece protección adicional contra el viento, que puede desprender las tejas del techo.Gracias a la tecnología, GAF puede afirmar que es pionero en otra cosa en la industria: ofrecer una garantía sin límite de viento máximo**.Cuatro beneficios de las tejas Reflector Series para propietariosLas tejas Timberline HDZ® RS le ofrecen varios beneficios.1. Cumplimiento de los códigos y reducción del costo de refrigeraciónEn California, las tejas RS pueden usarse para cumplir los requisitos de reflectancia solar de edificios residenciales altos, según se indica en el título 24, parte 6 del Código de Regulaciones de California de 2022 y el Código de Estándares Edilicios Ecológicos del condado de Los Ángeles. Ambos códigos fijan un índice de reflectancia mínima, denominado índice reflectivo solar (SRI, solar reflective index), que mide la capacidad de un material para reflejar el sol y la luz solar. Cuanto menor sea el valor de SRI (de 0 a 100), más caliente será un material bajo la luz solar. Cuanto mayor el valor, más frío será el material.Las tejas con un SRI más alto, como GAF Timberline HDZ® RS, reflejan más luz solar, ayudan a reducir la temperatura interna y la energía (y los costos) que se necesita para refrigerar su hogar.2. Colores oscuros y ricos que combinan con cualquier estilo o estéticaYa no tendrá que elegir entre colores oscuros, ricos y profundos, populares en la arquitectura moderna, y el cumplimiento de los requisitos de reflectancia. Además de ofrecer una opción en color carbón, el color de alta reflectancia más oscuro, los otros colores de la línea cuentan con mezclas de colores GAF High Definition® que le brindan a las tejas Reflector Series un aspecto dimensional similar a las tejas de madera.3. Protección contra algas verde-azuladasLas manchas de algas verde-azuladas, una cianobacteria llamada gloeocapsa magma, pueden reducir el valor de su hogar. Las tejas HDZ® RS incluyen la tecnología contra las algas GAF Time-Release, que utiliza cápsulas especialmente diseñadas impregnadas con miles de partículas de cobre. El cobre se libera de manera uniforme a lo largo del tiempo y evita el crecimiento de las algas durante muchos años. Gracias a esta tecnología, GAF ofrece una garantía limitada de protección contra las algas StainGuard Plus™ de 25 años*, que es especialmente beneficiosa en climas cálidos, húmedos y costeros como el de California.4. Garantía contra viento sin límite máximo de velocidad de vientoCuando se instala con la cantidad requerida de accesorios del sistema de techado GAF, la tecnología LayerLock® de las tejas Timberline HDZ® Reflector Series le permite a GAF ofrecer una garantía contra viento limitada WindProven™ de 15 años** sin límite máximo de velocidad de viento.Una opción elegante para los propietarios de CaliforniaSi vive en California, las tejas GAF Timberline HDZ® RS son una opción inteligente para cumplir los estrictos requisitos de reflectancia estatales y, al mismo tiempo, seguir el sentido estético y estilístico de la arquitectura moderna.

If you notice missing shingles on your roof, there's no need to panic. Missing shingles aren't an emergency, but you should still act quickly, especially during wet seasons. Your roof is a multilayered system designed to protect your home's structure and finishes from water damage.If you ignore missing shingles, moisture can get into your home, leading to issues such as rot, mold, and costly water damage. Replacing missing shingles quickly can mean the difference between a minor roof repair and a total roof replacement.So, here's how to spot missing shingles and hire a roofer to replace them.How to Spot Missing ShinglesLocating missing shingles, before leaks set in, can save you time, money, and peace of mind. Here are several ways to spot them before they cause bigger issues.Inspect Your Roof from the GroundScope your roof with binoculars for signs of missing shingles. Inspecting your roof from the ground helps prevent shingle damage from walking on the roof and, most importantly, fall-related injuries. Scan your roof from every angle that it's safe to do so, including from streets, sidewalks, and neighbors' yards if you have permission to do so.Check for Shingle ChangesSystematically check each shingle following a horizontal or vertical line. A missing shingle often sticks out as a color change in your shingle pattern. While you're at it, look for shingles that are cracked, curled, or sagging or that aren't aligned with the others. These can all be signs of shingle or roof damage.Review Your Roof for Damage after StormsRoof damage often happens as a result of extreme weather. Once it's safe to be outdoors, visually inspect your roof for damage. You can also survey the ground around your property to spot any shingles that may have blown off.Look Inside Your Home for LeaksCheck inside your home for longer-term signs of missing shingles. Evidence of leaks in your attic or water stains on your interior ceilings or walls can indicate wider-spread water damage in your home. If you notice anything out of the ordinary, have a roofing professional inspect the area (both inside and outside) for damage.Schedule a Professional Roof InspectionThe National Roofing Contractors Association recommends professional-level roof inspections twice a year—once in the spring and once in the fall. Like routine car maintenance keeps repair costs down, roof inspections can help spot small concerns before they potentially become expensive problems.How to Hire a RooferOnce you spot missing shingles on your roof, the next step is hiring a professional to replace them. Create a list of questions before you call around, so you can find a reliable roofing company that won't cut corners.If you have warranties, you may also want to check whether or not those have any requirements. For example, all GAF roofing shingles and qualifying accessories (the "GAF Products") come with the coverage provided by the GAF Shingle & Accessory Limited Warranty,** and you don't need to do anything at all to get it.How to Prepare for Roofing RepairsThough every contractor is different, confirm certain details before signing any contracts. Here's how you can ensure you and your contractor are on the same page before work begins:Communicate clearly from the start; this will help prevent frustration and unexpected costs.Before making a deposit, be sure you both agree on the quote and job details.Agree on the job's start date, plus a contingency plan if bad weather forces a rain check. Ask your roofer if they'll install a temporary tarp to prevent water damage in the case of a delay.Read your quote carefully. Confirm approximate labor costs and the color, style, and brand of shingles that will be installed.Ask about anticipated material quantities and estimated roofing material costs (like flashing, roofing nails, etc.).Confirm whether the repair job includes cleanup costs and if the roofer will remove any debris.When to Consider a Roof ReplacementLook at the big picture before replacing missing shingles. Consider your roof's age, any warranties on your roof system, the extent of the roof damage (both internally and externally), and whether the missing shingles are an isolated issue. Multiple missing shingles or frequent repairs could be a sign that you need a new roof.Ready to schedule a professional roof inspection? Contact a GAF-certified roofing contractor* to get started.*Contractors enrolled in GAF certification programs are not employees or agents of GAF, and GAF does not control or otherwise supervise these independent businesses. Contractors may receive benefits, such as loyalty rewards points and discounts on marketing tools from GAF for participating in the program and offering GAF enhanced warranties, which require the use of a minimum amount of GAF products. Your dealings with a Contractor, and any services they provide to you, are subject to the GAF Contractor Terms of Use.* *GAF Accessory Products covered under this limited warranty include: GAF Ridge Cap Shingles, GAF Starter Strip Shingles, GAF Leak Barrier Products, GAF Roof Deck Protection Products, and GAF Attic Ventilation Products.

Your roof is a long-term investment that helps protect your family, may improve your home's resale value, and crowns your home's aesthetic so finding a contractor that is qualified is very important. To help you choose a roofing contractor with confidence, here are three qualities to look for.1. Professional Experience and ReputationBefore you hire, do your research. Choose a company based on experience and reputation—not just price. If you decide on price alone, you may not be making the best choice.RecommendationsWord-of-mouth from trusted sources is a great starting place. Ask neighbors, friends, and online community forums for referrals.ResearchVisit the company's website to determine the products and services it offers—as well as the number of years it's been in business. Then, verify the company is licensed and insured.ReviewsNext, read reviews from multiple online platforms to learn about customer experiences. Resources could include Google Reviews, Yelp, Better Business Bureau, and the company's social media pages. While searching, look for info such as ease of interactions, professionalism during installation, cleanup after project completion, and overall satisfaction with the outcome.2. CertificationsFinding a contractor certified by a manufacturer typically indicates that a contractor has met the certification requirements of the manufacturer. For example, contractors certified by GAF must be insured and licensed in states where they operate (if required). GAF also considers factors such as years of roofing experience, credit rating and overall standing with the Better Business Bureau.Higher tiers of certification may be allowed to offer better enhanced warranties on qualifying roofing systems. For example GAF Master Elite® Contractors are entrusted to offer the GAF Golden Pledge Limited Warranty* on qualifying roofing systems, which provides up to 30 years of misapplication coverage.VerificationVerify contractor certifications whenever possible. For example, the GAF website lets you verify whether a company is certified by GAF by simply entering their phone number or contractor ID.AwardsIn addition to certifications, select contractors may also qualify for manufacturer awards. For example, the highest distinction a GAF Master Elite® contractor can earn is the GAF's President's Club Award. This award indicates that a contractor has demonstrated commitment to installing GAF roofing systems backed by GAF's strongest warranties and dedication to learning about GAF's products and services.3. Operational ApproachAfter identifying several contractors, consider these talking points when interviewing the contractors:ExperienceAsk the contractor whether it has experience installing roofs on the type of roof architecture you have.AvailabilityWhen do you need the project to start, and when can the company actually do the installation? If your roofing needs are urgent (leaks, damage, etc.), make sure they can perform the work in the timeframe you are looking for.EstimateAsk the contractor to provide you with an estimate. As a preliminary step, try using GAF's estimate tool. However, keep in mind that the estimate provided by the tool is non-binding and contractors will provide their own estimates. Review actual estimates from contractors closely to understand what is included. The cheapest option is not always the best. Consider experience, and reputation, too.Payment OptionsAsk your contractor about payment options, including payment and financing options to make sure you choose the best option for you.Starting Your SearchPrioritizing these qualities when looking for a contractor may help you find the right company for the job.Are you ready for a new roof?
