Roof to Wall Flashing: Why Details Matter for Single-ply Roofing Systems

Durante los últimos años, GAF ha organizado la Expo Latinos in Roofing para reconocer, celebrar y empoderar a los contratistas e instaladores de techos latinos. Este foro proporciona un entorno cómodo y acogedor en el que es posible establecer contactos, recibir formación y adquirir conocimientos, todo en español.En su tercer año, la cumbre se ha convertido en un recurso confiable para la comunidad de contratistas de habla hispana que aspiran a obtener conocimientos sobre cómo mejorar y crecer sus negocios de construcción y mantenimiento de techos. Las sesiones educativas abarcan temas esenciales para el éxito empresarial, como ventas, restauraciones a cargo de aseguradoras, construcción y mantenimiento de techos comerciales, liderazgo, mercadotecnia y productos para techos.La primera Expo Latinos in Roofing de 2024 se celebró los días 21 y 22 de junio en Los Ángeles y contó con la asistencia de cientos de profesionales del sector. Este evento, en el que se hizo hincapié especial en el fomento de la comunidad, incluyó una serie de propuestas, como una sesión de la recepción y la oportunidad de asistir a un partido de los Dodgers de Los Ángeles en compañía de los nuevos contactos allí establecidos.Este es un resumen de lo que el evento ofreció a los asistentes y de las experiencias que éstos compartieron.Traspasar las barreras lingüísticasAlan López, capacitador de GAF CARE, explica que los eventos Latinos in Roofing se desarrollaron cuando notó que una mayor cantidad de contratistas de origen hispano asistían a los eventos de GAF organizados en inglés. Para muchos de ellos, el inglés era su segunda lengua, por lo que era más difícil aprender y asimilar toda la información, ya que parte de ella se perdía en la traducción. López recurrió a los directivos de GAF, quienes se entusiasmaron con la idea de ofrecer recursos para los contratistas latinos, y organizaron la primera exposición en 2019.Abad Sarate, director general de Asa Pro Roofing en Seattle (Estado de Washington), considera que el hecho de que la conferencia se desarrollara íntegramente en español fue fundamental para aprender y comprender la información presentada. "Para nosotros es muy importante entender el contenido en nuestro idioma principal. Es esencial", afirma. "Y contar con este tipo de conferencias para muchos contratistas latinos nos llena de orgullo", agrega. Y añade: "Cada vez son más los latinos propietarios de empresas de construcción de techos y, la verdad, me alegro mucho. Además, como latino, me siento muy orgulloso".Luis Velásquez, de Entrenando Latinos in Roofing, concuerda en que el hecho de que la cumbre se presentara en español fue importante para el éxito logrado entre los asistentes. "Nosotros, los latinos de primera generación, que no fuimos a la escuela y que venimos de países pobres, tenemos un obstáculo: no entendemos el inglés al 100 %, no somos totalmente bilingües", señala. "Por eso, cuando logramos entender lo que vemos y cómo podemos ponerlo en práctica, la ganancia es completa", indica y concluye: "Cuando pongamos conocimiento en nuestra cabeza, la cabeza pondrá dinero en nuestros bolsillos".Crear una tradición anual para los profesionales del techadoLa adquisición de conocimientos para el éxito empresarial fue uno de los temas clave de la edición de este año. Las sesiones informativas, las conferencias magistrales y las demostraciones sirvieron para que los asistentes conocieran nuevos productos y obtuvieran nuevos conocimientos, al tiempo que se relacionaban con otros latinos del sector de la construcción y el mantenimiento de techos. Muchos asistentes reiteraban su visita, lo que confirma el valor de este evento.Abad Sarate, quien ya ha asistido dos veces, explica que la reunión anual ha sido fundamental para el desarrollo de su empresa: "Ha sido una parte excepcional de nuestro crecimiento gracias a todo el conocimiento que adquirimos aquí", comparte. "Regresamos a casa con mucho más conocimiento. Y, a fin de cuentas, el conocimiento es poder. Incorporar ese conocimiento a la empresa nos ha beneficiado mucho", señala.Para Marcos Sierra, de Sierra Group Roofing & Solar, es ya la tercera vez que acude a la exposición por las oportunidades de establecer contactos y de formación que ofrece. "La razón por la que vuelvo es, primero, para ver a mis colegas de otras partes de Estados Unidos. En segundo lugar, porque cada vez que vengo aprendo algo nuevo. Y, en tercer lugar, para perfeccionarme, perfeccionarme y perfeccionarme para poder hacer crecer nuestro negocio", afirma.Apoyo a los contratistas más allá de la ExpoGAF puso en marcha la iniciativa Latinos in Roofing con el objetivo de crear recursos y una comunidad para contratistas e instaladores hispanohablantes.

As a commercial roofing contractor, you're responsible for choosing the right materials for each job. But with so many options available, making a decision can be difficult.Increasingly, industry professionals have been turning to silicone roof coatings for their strength and durability. These coatings can help extend the life of a structurally sound roof and potentially save property owners time and money by delaying a full reroof. Plus, their restoration properties work great with most commercial roofing systems, like EPDM, built-up, bitumen, and metal roofs. What Are Silicone Roof Coatings?Silicone coatings are high-performance, waterproof protective roof coatings. Adding this coating to a structurally sound roof can help extend the life of the existing roof. Silicone is inorganic, so it can maintain its properties in inclement weather conditions. It's also flexible and can absorb most normal roof movement to help avoid cracking and losing its protective features.Benefits of Silicone Roof CoatingsIn addition to flexibility and extending the life of the existing roof, silicone coatings offer several other benefits. Laura Soder, senior product manager for liquids and coatings at GAF, explains that GAF silicone coatings are designed to help protect against leaks and provide related advantages.UV Ray ProtectionThe major benefit of silicone coatings is ultraviolet (UV) ray protection. "GAF silicone is formulated with titanium dioxide, providing exceptional UV stability and high solar reflectance," she says. This UV protection can help lower roof top temperatures, which may translate into more efficient operation of roof top units.Cost-EffectiveSilicone coatings are cost-effective solutions that can help delay the cost of materials and labor needed to replace the entire roof. They work great with most commercial roofs and pair exceptionally well with metal roofs.Restores and Helps Extend the Life of the Existing RoofSoder notes that silicone coatings adhere well to metal roofs, making them an excellent way to extend the service life of metal roofs. Before application, brush away light rust or spot-treat heavier rust. "There are a lot of metal roofs out there, and for those that are structurally sound and require only moderate restoration, you can easily add years to the roof's life by coating them with silicone," she says.Moisture-ResistantSilicone coatings are also known for their moisture-resistant capabilities. Since silicone is inorganic, it resists degradation in areas that pond water, making it an ideal choice in areas that experience rain or snow.Works in Hot and Cold WeatherSilicone has a wide temperature application range. Because it doesn't contain water, you can apply it at lower temperatures than acrylic and other roof coatings. It provides a monolithic, seamless waterproofing layer over existing metal roofs. Silicone will also flex with metal in cold and hot weather.How Silicone Compares to Elastomeric CoatingsCompared to acrylic and other elastomeric roof coatings, silicone has some advantages.Acrylics are water-based protective coatings with UV resistance —but they shouldn't be installed where there is ponding water, as they can break down and start delaminating. Silicone is a moisture-cure material, meaning it reacts with moisture in the air and cures to a finished film.Soder explains that both materials are flexible and appropriate for use over metal. But if you have any standing water, acrylic isn't the best choice. "While silicone is more expensive, it typically weathers at a much slower rate than other coatings," she says. That said, one of silicone's drawbacks compared to other elastomeric roof coatings is that it's slippery when wet.Navigating Installation and ApplicationWhile silicone coatings can help extend the life of an existing roof, Soder notes it's best to install the coating before the end of the existing membrane's service life.Since leaks tend to happen at roof seams, add silicone sealant to these areas. Sealants are formulated differently than coatings—they use different silicone polymers, giving them a heavier body and stronger build. Silicone sealants are formulated for high-stress areas and can help absorb movement at critical points in the roof. They work hand in hand with a silicone coating to protect the roof.Before you apply any coating, ensure the roof is clean, dry, and sound. "Clean means free of contaminants, dust, oils, leaves, and other debris," Soder says. You can use GAF Cleaning Concentrate to power wash your roof.Since silicone is moisture-cure, the roof needs to be dry before applying. Coating over a wet surface can affect adhesion and is often one of the biggest mistakes you can make when installing. You want the coating to start the curing process from moisture in the air, not from moisture on the roof.How to Apply Silicone CoatingsApplying a silicone roof coating involves five steps:Clean any debris off the roof and test that the coating will properly adhere to the surface.Ensure the roof is in sound condition. Repair broken sheet metal, and replace missing or damaged fasteners.Treat all seams and fasteners with silicone sealant like GAF Silicone Mastic. Apply it at 60 mils or 1/16-inch wet thickness with a brush.Use the same sealant on any curbs, penetrations, and drains.Finally, apply the silicone roof coating to the entire roof. Some coatings, like GAF Unisil Silicone, require two coats, while others such as the GAF High Solids Silicone may need just one.Understanding Maintenance Needs and LongevityMaintaining a silicone roof coating is essential. Addressing issues before they become problematic can help minimize the cost of repairs and maximize the service life of the coating.As the roof flexes over time, issues with the seams might develop. A good rule of thumb is to get a roof inspected every six months. Applying a silicone sealant can help address areas with leaks or cracks. Silicone sealant is UV stable and doesn't require a top coat, according to Soder.Adding Silicone Roof Coatings to Your ToolboxWith many benefits, silicone roof coatings should be front of mind when planning roof restoration projects. And with several options available, you can choose the best type for each roof you work on. Have more questions about roof coatings?

As part of its effort to build resilient communities, GAF provides students across the country with opportunities to gain work experience and hands-on training. The GAF co-op program offers participants autonomy and leadership in project management, engineering design, budgeting, project installation, and more.Over the years, the GAF co-op recruiting program has helped students advance academically, grow professionally, and earn competitively while working full time with North America's largest roofing and waterproofing manufacturer.How the GAF Co-Op Program WorksThe program gives students high-impact, hands-on experience in the manufacturing sector. They perform meaningful work alongside supportive GAF mentors and senior leadership while earning a competitive wage. Participants can also receive credits from their university, which they can apply to their coursework.Differences between a Co-op and an InternshipInternships and co-ops have a few notable differences. At GAF, the main difference is the length of time. Internships at GAF usually last 10 weeks, but the co-op program is six months. While internship programs often allow students to stay enrolled in school and complete coursework as they gain professional training, co-op participants must take a semester off to gain full-time work experience.Not all companies pay internship participants for their work. However, at GAF, both interns and co-op students are paid competitive hourly wages. GAF also offers financial relocation assistance for qualifying co-op program candidates.Finally, participants in the GAF programs are there to learn real skills that will help them advance their future careers. GAF interns and co-op students are given the same responsibilities, and chances to collaborate on major projects, as full-time employees.Recent GAF Co-Op Success StoriesMin U, a mechanical engineering student at the University of Maryland, says he "fell in love with manufacturing" thanks to his placement on an engineering project. The experience gave him a firsthand account of the role engineering plays in manufacturing safety, profit, and operations. This ultimately led him to shift his career goals from construction management to manufacturing engineering.When Dante Stellar, an industrial engineering student at Virginia Tech, met GAF representatives at a career fair, he says he didn't expect to become a self-proclaimed "nerd for shingles" and develop a passion for manufacturing. However, that's exactly what happened. And that newfound passion paid off when Dante won Student of the Year from Virginia Tech's Cooperative Education and Internship Program. Dante notes he's now eager to return to GAF and aspires to become a manufacturing leader in the world of shingles.Michael Hesseltine, an electrical engineering student at Texas A&M University, chanced upon a GAF co-op recruiting listing online. After a series of interviews, he landed a project engineering co-op in Ennis, Texas. Working with the Ennis team on major projects solidified his manufacturing engineer career goals.Co-Op Students Complete Meaningful WorkStudents in the GAF co-op program are involved in meaningful projects and get to see their work's impact on day-to-day operations.During his time in Ennis, Michael designed a baler that compacts fiberglass scrap, reducing site disposal trips and costs. He also oversaw renovations of the site's maintenance mechanical break room from start to finish. He notes that his favorite contribution was helping design the electrical system for a dewatering press.In Baltimore, Min's core project was ensuring site compliance with state regulations for discharging stormwater runoff. Min managed all the project contractors and budget with his manager's and mentor's support. Throughout his time there, Min was exposed to Lean methodologies, 5S, risk mitigation, insurance compliance, cost control, and procedure standardization. He gained an overall understanding of manufacturing equipment and business.At the Tampa plant, Dante worked on a rock pad storage expansion project and installed a starwheel machine guarding the manufacturing line, among other important projects. According to Dante, the defining moment of his co-op experience was his granule silo refurbishment project, which involved replacing eight silos, including floor plates and support beams.Dante explains the trust and opportunities his mentors provided were key to his success. "At GAF, I was given the chance to interact with contractors, and immerse myself in the plant, which accelerated my learning," he says.Co-Op Students Build Professional RelationshipsThrough "lunch and learn" sessions, leadership speaker series, meetings with senior leadership, and mentorship, co-op students build long-term professional relationships.Dante was given the chance to showcase the coordination and safety efforts involved in his granule silo project to the GAF executive leadership team in Parsippany, New Jersey.For Min, getting the right feedback to grow meant having the right relationships. He notes the mentorship from his manager Alex Smith and engineering manager Mike Kloda was key to his progression. As advice to future co-op participants, he explains that "everyone is here to help... but it's up to you to drive that forward."Meanwhile, the autonomy and leadership opportunities program leaders gave Michael allowed him to grow technically and professionally. "I was often the go-to person for projects, managing contractors and ensuring everything was on track," he says.Joining an Industry Filled with OpportunityThe GAF co-op program helped Min, Michael, and Dante start and solidify their careers in manufacturing engineering. Following their experience, each student was excited and motivated by the autonomy, responsibility, and growth opportunities they were given. In fact, Min has since accepted a full-time role as a project engineer at the GAF plant in Baltimore. His expected start date is July 7, 2025.GAF is committed to fostering diversity, equity, and inclusion throughout the organization.
