A collage of different roofing materials

Choosing roofing materials for your home is a big, exciting decision. Beyond keeping your family safe and comfortable, your roof majorly impacts curb appeal. Most roofs occupy 40% of a home's visual exterior, so it makes sense that you'd want roofing materials that look good!

But there's more to deciding on a type of roofing material than color and design. Your regional climate, local building and fire codes, and budget all matter. Plus, your home construction factors into whether slate tile, clay tiles, asphalt shingles, metal roofing, or another roofing material might be best.

Here, we dive into four of the most common roofing materials to help you make the best choice possible.

Asphalt Shingles

Asphalt is the most popular roofing material in the U.S. In fact, four out of five homeowners choose asphalt shingles. Most asphalt shingles are made from a fiberglass base that's been soaked in asphalt and coated with mineral granules to create a durable roof covering.

There are two categories of asphalt shingles: traditional 3-tab shingles, which are more affordable and built from a single layer, and laminate or architectural shingles, which can be two or three layers. 3-tab shingles are used due to their affordability, but laminate or architectural shingles are more popular due to their durability and greater range of design options.

Here's when to consider asphalt:

  • You have architectural roof details with tricky flashing needs.
  • You want distinctive color options and a variety of designs that can match the style and aesthetics of your home.
  • You prioritize ease and speed of install.
  • You want the wood shingle look with high fire and wind resistance. GAF Timberline® HDZ™— North America's top selling shingle has the highest roofing fire rating: UL Class A, Listed to ANSI/UL 790 and meets the industry's toughest wind tests ASTM D7158, Class H and ASTM D3161, Class F. In addition, when installed with the required combination of 4 qualifying GAF Accessories, it qualifies for the WindProven™ limited wind warranty*, the industry's first wind warranty with no maximum wind speed limitation.

Slate Roofs

Slate has a distinctive look that's often associated with high-end architecture and traditional Northeastern homes. Slate is metamorphic rock that's mined and cleaved into thin sheets for roofing. It's typically dark gray, but may be found in other colors depending on where it was mined.

There are three quality ratings for natural slate roofing—S1, S2, and S3. An S1 rating offers the highest resistance to water absorption and weathering, as well as the highest break strength.

Slate tile is attractive and offers natural durability. Here's when to consider slate:

  • You want the natural insulation that slate provides
  • You love the look and the durability of an S1-rated slate tile like GAF Slateline®
  • Your home construction can support the weight of a slate roof
  • You want the natural durability that slate offers against the elements

Metal Roofs

Metal roofs come in a range of prices and types. Metal roofs can impart a modern, clean look when done in stainless steel, or lend a period aesthetic when done in copper. You can choose between metal shingles or standing seam metal roofing.

Popular metals include galvanized steel, aluminum, copper, zinc, and stainless steel. The metal you choose impacts your roof's strength and durability. It's important to note that some metal materials can dent easily from weather events such as hail. Here's when to consider metal:

  • You want the fire resistance that metal provides
  • You want the unique aesthetic of metal
  • You don't mind the noise of a metal roof when it rains or storms
  • You can invest in a quality metal material that will last

Clay Roof Titles

Clay roof tiles are naturally beautiful and commonly associated with Southwestern and Mediterranean-style homes. Clay tiles come in a range of colors and designs. Although they are traditionally handmade, most clay tiles are now machine-made.

Concrete tiles replicate the look of clay and typically cost less than clay. Clay roofs are hardy and durable, but they can become brittle over time and break more easily than some other roofing materials. Here's when to consider clay:

  • Your roof meets the typical slope requirements (2:12 or greater) for clay or concrete tile installation
  • Your home can support the weight of a clay tile roof
  • You want the fire, wind, and impact resistance of clay
  • You love the look of clay tile
  • You're able to afford clay roofing

How to Put Up Holiday Lights and Seasonal Decor Without Risk

While it can be fun to put up holiday lights, it's traditionally had its share of downsides. In addition to requiring a ladder, adding seasonal cheer to a home's exterior previously involved driving screws, nails, or staples into the roof or siding. The small holes these fasteners create can allow moisture to penetrate the roofing system, potentially leading to leaks, mold, and mildew.These days, you can choose many options to spread holiday cheer without damaging your home or taking on unnecessary risks. Here are the most effective ways to decorate for the season.Consider Decor That Doesn't Involve the RoofThe safest way to bedeck your home for the holidays is to decorate another part of the house or your yard, away from the roof. Here are a few ideas.ProjectorsLight projectors shower your home with a moving light display, featuring anything from snowflakes to traditional holiday characters. With many options, you're sure to find one that suits your house and neighborhood. And since the projector units sit close to the ground, you don't risk damage to your home and don't need a ladder to install them.InflatablesInflatables are staked into the ground and can help create a variety of holiday themes, from the classic nativity scene to an eye-catching menorah. They're easy to install and won't damage your home. However, inflatables are susceptible to weather events—during high winds or heavy snowfall, you may want to unplug or turn off the fan to prevent them from taking flight or creating a risk of electric shock.Tree LightsYou can hang lights from trees, landscaping, or other structures in your yard. Stringing lights around bushes, up light poles or tree trunks, and under a carport are all good alternatives to hanging them on the roof.How to String Holiday Lights on Your HouseIf you really want to put up holiday lights on your house, you can do so safely without damaging your roof or siding.Seek HelpOnly use a ladder with a partner nearby to help maintain stability and provide assistance. If you don't feel comfortable climbing a ladder or want additional help, contact a roofing contractor.Use Plastic ClipsYou can mount holiday lights using plastic clips that attach to gutters or shingles. The most common ones clip to the gutter's edge and hold either individual lights or the wire between them. You can also use siding clips to string lights vertically.Alternatively, you can install roof peak clips, which grip the shingle's edges at the top of the roof. They require access to the roof ridge, so professionals often use them.To remove the lights at the end of the season, take down the clips individually. Don't pull on the string of lights, as doing so could damage your gutters or the light string.Try Magnetic ClipsYou can use magnetic clips to attach individual bulbs or sockets to metal roofs or flashing. You can easily take them down by pulling on the string of lights (in this case, it's OK).While you're working around your roof, take a few minutes to inspect it for potential damage or quality issues. Contact a contractor if you have any concerns.Holiday Lighting OptionsSelect lights that are properly rated for outdoor use. LEDs are often recommended due to their energy efficiency, and they don't heat up like incandescent bulbs. You can also plug in multiple strings to the same outlet without fear of overloading the circuit, making LED lights more versatile.When it comes to types of holiday lighting, you have a few options.Large BulbsIt doesn't get much more traditional than large bulbs. You can use clips to ensure they're all pointing the same way, or string the cord through them for a more carefree look.Mini LightsMini lights don't put out as much light as large bulbs, so they may not be the best option for the roof. However, they're great for windows, trees, or indoor displays.Icicle LightsIcicle lights have strings of small bulbs that hang down from the gutter or roof to look like icicles. Use clips to attach the main string to the gutter line.Raindrop LightsRaindrop lights are animated to look like raindrops. You can hang them in a cluster in a small area or spots where traditional string lights don't work.Decorative Bulb CoversDecorative bulb covers give your home a unique look. You can get them shaped like snowmen, stars, ornaments, or other holiday motifs.Smart LightsSmart lights are the newest trend in holiday lighting. An app lets you control the lighting colors, patterns, intensity, and blinking speed so you can create your own unique light show. When paired with music, your home will become a neighborhood attraction.Remember to Prioritize SafetySafety should always be your first priority when you put up holiday lights. If you need a ladder to achieve your desired design, don't climb one without a helper nearby, and ensure you have the right ladder for the job. Also, attaching lights to your house with temporary clips instead of permanent fasteners can help keep your roofing system healthy.If you notice any roof damage or concerns while planning your holiday decorations, don't hesitate to contact a roofing contractor that's certified by GAF. They have the expertise to assess and address any roofing issues, ensuring your home stays protected throughout the holiday season and beyond.Whether you hang lights or opt for other outdoor decor, you can spread holiday cheer this season safely and creatively.

How GAF's Co-Op Program Makes a Difference in Students' Lives

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. It believes a talented and diverse organization can drive innovation, growth, and transformation more effectively. To further bolster inclusivity, GAF offers academic and merit scholarships, partners with the Thurgood Marshall College Fund to recruit from the nation's most diverse talent at Historically Black Colleges and Universities and Predominantly Black Institutions, and reaches out to candidates at career fairs nationwide.Bright and motivated minds who want to explore manufacturing have plenty of opportunities.

How Metal Roofing Materials Withstand Extreme Weather

Harsh weather can damage your home, leading to expensive repairs or even making it unlivable in the worst cases. While you can't control the weather, you can take steps to try and minimize damage—like installing a durable roof.If you live in an area prone to harsh weather, metal roofing materials can help protect your home from elements like hail, rain, snow, and wind. Here's what you need to know about metal roofs and the protection they offer.Wind and Impact ResistanceMetal roofing shingles can help resist high winds due to their interlocking system, which helps provide wind uplift resistance. Interlocked panels help keep the materials in place and reduce the areas where winds can cause uplift, like the eaves and edges. Metal's smooth surface also lets air flow easily over it.The GAF TimberSteel™ Premium Metal Roofing System passes the ASTM D3161, Class F test method, wind resistance for the ASTM D3161, the highest possible category for wind resistance of steep slope roof coverings. This means it has been tested to handle 110 mph wind speeds under the Standard Test Method for Wind Resistance of Steep Slope Roofing Products (Fan-Induced Method)*.GAF TimberSteel™ metal field shingles are classified to UL2218 Class 4 Impact Resistance, the highest rating available.Moisture ResistanceOffering excellent protection against wind-driven rain, the GAF TimberSteel™ passes the TAS -100 Wind-Driven test* for rain water intrusion.Custom Snow SolutionsWhile rain is one problem, snow can also damage your roof. Snow adds a heavy load to your roofing structure, and moisture can enter your home as it melts if given the opportunity.Metal roofs have a smooth surface that allows snow to slide off which may help prevent ice dams that form when snow melts and refreezes. Custom snow guards are available in the colors of the TimberSteel™ system to complement your roof.UV Radiation ResistanceSunlight can break down roofing materials over time. Metal roofing helps resist the sun's harmful ultraviolet (UV) rays which may contribute to its longevity.Consider Metal RoofingWith more areas experiencing extreme weather, homeowners all over the country may benefit from considering metal roofing materials.Does metal roofing sound right for your home?
