Top Six Common Roof Types & How to Pick One for Your Home

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?

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?

All homes can benefit from a little tender loving care, no matter the age or location. Making occasional updates to beautify your property can help maintain its character while enhancing your pride and appreciation. In some cases, home improvement projects can even boost the resale value.If you want to upgrade the look of your home and green spaces without getting on the roof or breaking the bank, there's no shortage of options. Here are four DIY ideas for low-maintenance front yard curb appeal.1. A Fresh Coat of PaintPainting is one of the simplest and least costly DIY home projects, requiring only primer, paint, and a brush. In fact, the most complicated part of painting projects is often choosing what to paint and what colors to use. However, this can be one of the highest-impact, low-maintenance front yard curb appeal projects.Painting your shutters, trim, or even just your front door can give your home a quick facelift. A great way to make your home look as cohesive as possible is to stick to its existing colors and undertones. You can achieve this by keeping the trim or shutter colors within the same color family as your roof.For example, if you have a white home with Hunter Green GAF Timberline HDZ® shingles on the roof, consider a similar shade of green for the shutters and trim. Or, if you have a stucco house with a cooler-hued roof, you can paint your shutters a soft gray or light blue for a modest pop of color.If you're feeling adventurous, consider painting your front door a fun color that will catch the eye and welcome your guests. For cooler-toned homes, try a front door in navy, royal, or even sky blue. For warmer-toned homes, you can be extra playful and paint your front door a bright red.When painting, remember to properly prep and prime all surfaces and use exterior paint. If you plan to refresh your shutters, it's best to remove them from the hinges and lay them flat while working.2. Updated LandscapingLandscaping is another fun way to add front yard curb appeal, but it can feel a little more daunting than an afternoon of painting. To start, visit your local nursery and learn about suitable plants for your area. Figure out how much upkeep and irrigation certain shrubs require, when particular flowers bloom, and the amount of sunshine each plant needs. You may want to dot your landscape with bushes that bloom throughout the year, or you may want a simple and calming lawn filled with lush shades of green. Either way, an expert at your local nursery can help.However, if you only have one afternoon to dedicate to your landscape, you can still make an impact. One quick way to upgrade your property's look is to fill terracotta pots with seasonal flowers in your favorite colors. Place them flanking the front door or beside the mailbox. If your home has a lot of windows, plant beautiful, low-maintenance flowers in windowsill boxes. The best part about potted plants is they're transportable, and you can change the blooms with the season or your mood.As you update your landscaping, choose a color scheme and appearance that complements your home's style and design. If you have a more traditional home with brown Weathered Wood GAF Timberline UHDZ® shingles on the roof, for instance, you could create a rustic, English-style garden that's filled with bursts of colorful flowers. If your home is more modern, on the other hand, stick with a simple landscape design that uses a subdued color palette. You want your front yard to feel connected with the rest of your home.Home featuring GAF Timberline UHDZ shingles in Weathered Wood.3. Improved Walkway DesignAnother DIY project that can give your home low-maintenance front yard curb appeal is improving your walkway. Enhancing your yard's hardscaping can make your home feel more cohesive.If your property has existing gravel walkways, consider matching the color to your home. Gray gravel stones complement a cooler-toned home, and ivory/beige stones work well for a warm-toned home. For instance, if your roof is a color similar to Oyster Grey GAF Timberline HDZ® shingles, consider using slate or bluestone; if it's on the warmer side, use brick.If you like the look of paver stones, pick up lightweight options at your local hardware store and use them to create intricate, eye-catching designs.Home featuring GAF Timberline HDZ shingles in Oyster Grey4. Elegant LightingAn impactful DIY tip for jazzing up your home's curb appeal is upgrading your exterior lighting. Soft, warm lighting can add elegance and offer dramatic flair. This complements homes with GAF Timberline® NS shingles that provide a natural shadow effect.Consider adding a sconce by the front door to make your home feel inviting and cozy. Place outdoor solar-powered lights along walkways. You can also add solar lights at the base of trees to uplight them, creating a sophisticated look at night. As added benefits, solar lights require no hard-wiring and don't affect your electricity bill, which makes them a great low-maintenance front yard curb appeal addition.There's No Place Like Your HomeGiving your home upgraded curb appeal through painting, landscaping, hardscaping, and lighting can make a big difference without requiring too much time or money. In addition to giving you a newfound sense of pride, your neighbors may also appreciate the property's updates. Best of all, these exterior DIY projects can potentially increase your home's sale price. It's often easier for buyers to envision themselves in a beautiful, well-maintained home.If you want to take your home's exterior to another level, think about upgrading your roof. A new roof requires less maintenance and can help refine your property's appearance.
