House with a gable roof

Does your roof have a slope that allows rain and melting snow to drain into gutters or off the eaves? If so, you likely have a gable roof.

While there is a wide range of roof designs, a gable roof is one of the most popular roof types, especially because of their ability to balance aesthetics and utility. Let's take a closer look at what this roof type entails.

What Is a Gable Roof?

This type of roof features two peaked sides that meet at a ridge line. The two sloping sides create end walls to form an "A" shape—a triangular extension called a gable—at the top on each end of the house. Traditionally seen in ranch-style or Cape Cod homes, gable-style roofing systems shed water well, making them one of the most popular options across North America.

How Does a Gable Roof Compare to a Hip Roof?

Both hip roofs and gable roofs are popular choices for residential homes, but they're quite different. Hip roofs slope back from all four roof sides down toward the walls of the home, which sit under the eaves. A hip roof has no vertical ends, and the "hip" is actually the angle formed where two sides meet.

With gable roofs, on the other hand, only two sides slope downward. The other two sides extend from the bottom of the eaves toward the peak of the ridge line.

What Are the Benefits of a Gable Roof?

Gable roofs provide versatility and durability that work with many styles of homes, making them a cost-effective and smart choice in most parts of the country. Because they have a simple design and their framing doesn't need to be constructed onsite, gable roofs are typically easier to install, and therefore more affordable than hip roofs. Gabled roofs also allow for more ventilation, giving homeowners more available space underneath the roof for features such as vaulted ceilings and attic space.

These types of roofs work well to shed water and snow thanks to their steep pitch, making them excellent choices for homeowners who live in areas that receive heavy snowfall. Gabled roofs also tend to provide good water drainage. The GAF lifetime roofing system is a great roofing system for your gable style roof. When you install a GAF Lifetime Shingle and at least three qualifying GAF Accessories, you get a Lifetime Limited Warranty on your qualifying GAF products.*

What Styles Do Gable Roofs Come In?

Some builders combine both hip roofs and gable roof types. What is a gable roof doing alongside elements of a hip roof? The end result often creates a more interesting design. For instance, a Dutch gable roof is a hip roof with a small gabled section on the upper section. Another variation is a half-hip roof, which adds a small hip section sloping toward the ridge onto a gable roof. Bringing elements of both types of roofs together can result in beautiful designs that offer better overall curb appeal.

There are many types of gable roofs. Most have equal-sized roof decks extending to the side walls of the house and sometimes beyond them.

  • Cross-Gabled: If a home's floor plan requires a T-shaped house, the roof is cross-gabled, where two gable roof lines meet at a 90-degree angle. Houses that have garages, dormers, porches, or additions also use a cross-gable roof structure.
  • Side-Gabled: Gabled roofs that show their slanting side on the front of the home are called side-gabled, while those where you see the pointed wall are called front-gabled.
  • Open Gable: An open gable (or pyramid roof) consists of a hip roof on a square structure. Here, the sides all join up to form a single peak. A box gable roof features two different slopes, where the lower angle is much steeper than the higher one.
  • Gambrel: Another type of gabled roof called a gambrel, or barn-style roof, features a multi-sided hip roof with two sloped sections—one flat part close to the ridge and one close to the eaves that features a sharper drop. These roofs allow for the maximum amount of usable space under the roof.
  • Flying Gable Roof: A flying gable roof has a ridge overhang that extends out farther than the eave to form a point at the end of the ridge. A front gable roof is usually seen on Colonial-style homes and is placed at the front to highlight the entrance and add coverage to the porch or entryway.

Does Moss on a Roof Die in Winter?

As it gets colder, you might wonder: does moss on a roof die in winter like other pesky plants? It's a common myth. However, while you might hope winter weather will eliminate the moss, this isn't the case. Even if the moss looks dried out when temperatures drop, it goes dormant and absorbs water like a sponge. Before long, it will continue growing and become more difficult to get rid of as it spreads across your roof, even after the winter season.Why You Should Remove Moss from Your RoofIf you don't remove moss from your roof, it can wreak havoc on shingles, eating away at their protective coating. Moss roots also grow in between shingles and underneath the structure. This can degrade the shingles and push them apart as temperatures drop, allowing water to penetrate and leak into your home.Moss growth can also prevent proper water drainage and result in bacteria or mold growth, rotten underlayment, and damaged framing. It compromises the roof's ultraviolet protection, too. Left to grow into a thick layer, moss can reduce your roof's lifespan.The Difference between Moss and AlgaeIt's also important to know the difference between moss and algae, and how to prevent or remove both to extend the life of your roof. Moss is a herbaceous plant that absorbs nutrients and water through its leaves, producing spores to reproduce. It spreads across your roof as it grows. Algae are flat, slimy, green aquatic plants that lack leaves, stems, or flowers. They tend to grow on moist areas of your roof, causing dark stains. Algae are usually found in areas where water drips overhead. If you suspect algae on your roof, consider installing algae-resistant shingles.How to Remove Moss from Your RoofSince the answer to 'does moss on a roof die in winter?', is no, now's a good time to hire a professional roofer to get rid of it. Moss is resilient, and you can't simply remove it by hand. They'll remove the moss using a chemical solution, and they can replace any damaged shingles to restore your roof's integrity.It's best to rely on a professional who can eliminate the moss while also inspecting your roof for damage. Don't try to use a pressure washer or any weed killers not designed for moss, as these can stain or damage your roof.How to Prevent Moss GrowthSince moss thrives in damp, shady spots, trimming trees to allow more sunlight onto your roof can help deter its growth. Also, regularly clear away leaves, twigs, and other debris, which helps moss grow, and clean your gutters frequently to prevent water buildup. In addition to these tasks, scheduling regular roof inspections can help you catch any issues early.You can also install a zinc strip, such as GAF Master Flow® Zinc Moss & Mildew Preventer, near the roof ridge to help protect your roof against moss, algae, and mildew growth. The metal strip oxidizes over time, and as water washes over the roof plane, it creates an undesirable environment for moss.By proactively removing moss and preventing its return, you'll protect your biggest investment: your home. Contact a GAF-certified roofing contractor* to ensure it's removed effectively.*Contractors enrolled in GAF certification programs are not employees or agents of GAF, and GAF does not control or otherwise supervise these independent businesses.

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?

Are Hybrid Roof Assemblies Worth the Hype?

How can roofing assemblies contribute to a building's energy efficiency, resiliency, and sustainability goals? Intentional material selection will increase the robustness of the assembly including the ability to weather a storm, adequate insulation will assist in maintaining interior temperatures and help save energy, and more durable materials may last longer, resulting in less frequent replacements. Hybrid roof assemblies are the latest roofing trend aimed at contributing to these goals, but is all the hype worth it?What is a hybrid roof assembly?A hybrid roof assembly is where two roofing membranes, composed of different technologies, are used in one roof system. One such assembly is where the base layers consist of asphaltic modified bitumen, and the cap layer is a reflective single-ply membrane such as a fleece-back TPO or PVC. Each roof membrane is chosen for their strengths, and together, the system combines the best of both membranes. A hybrid system such as this has increased robustness, with effectively two plies or more of membrane.Asphaltic membranes, used as the first layer, provide redundancy and protection against punctures as it adds overall thickness to the system. Asphaltic systems, while having decades of successful roof installations, without a granular surface may be vulnerable to UV exposure, have minimal resistance to ponding water or certain chemical contaminants, and are generally darker in color options as compared to single ply surfacing colors choices. The addition of a single-ply white reflective membrane will offset these properties, including decreasing the roof surface temperatures and potentially reducing the building's heat island effect as they are commonly white or light in color. PVC and KEE membranes may also provide protection where exposure to chemicals is a concern and generally hold up well in ponding water conditions. The combination of an asphaltic base below a single-ply system increases overall system thickness and provides protection against punctures, which are primary concerns with single-ply applications.Pictured Above: EverGuard® TPO 60‑mil Fleece‑Back MembraneOlyBond 500™ AdhesiveRUBEROID® Mop Smooth MembraneMillennium Hurricane Force ® 1-Part Membrane AdhesiveDensDeck® Roof BoardMillennium Hurricane Force ® 1-Part Membrane AdhesiveEnergyGuard™ Polyiso InsulationMillennium Hurricane Force ® 1-Part Membrane AdhesiveConcrete DeckPictured Above: EverGuard® TPO 60‑mil Fleece‑Back MembraneGAF LRF Adhesive XF (Splatter)RUBEROID® HW Smooth MembraneDrill‑Tec™ Fasteners & PlatesDensDeck® Prime Gypsum BoardEnergyGuard™ Polyiso InsulationEnergyGuard™ Polyiso InsulationGAF SA Vapor Retarder XLMetal DeckWhere are hybrid roof assemblies typically utilized?Hybrid roof assemblies are a common choice for K-12 & higher education buildings, data centers, and hospitals due to their strong protection against leaks and multi-ply system redundancy. The redundancy of the two membrane layers provides a secondary protection against leaks if the single-ply membrane is breached. Additionally, the reflective single-ply membrane can result in lower rooftop temperatures. The addition of a reflective membrane over a dark-colored asphaltic membrane will greatly increase the Solar Reflectance Index (SRI) of the roof surface. SRI is an indicator of the ability of a surface to return solar energy into the atmosphere. In general, roof material surfaces with a higher SRI will be cooler than a surface with a lower SRI under the same solar energy exposure. A lower roof surface temperature can result in less heat being absorbed into the building interior during the summer months.Is a hybrid only for new construction?The advantage of a hybrid roof assembly is significant in recover scenarios where there is an existing-modified bitumen or built-up roof that is in overall fair condition and with little underlying moisture present. A single ply membrane can be installed on top of the existing roof system without an expensive and disruptive tear-off of the existing assembly. The addition of the single-ply membrane adds reflectivity to the existing darker colored membrane and increases the service life of the roof assembly due to the additional layer of UV protection. Additionally, the single-ply membrane can be installed with low VOC options that can have minimum odor and noise disturbance if construction is taking place while the building is occupied.Is the hybrid assembly hype worth it?Absolutely! The possibility to combine the best aspects of multiple roofing technologies makes a hybrid roof assembly worth the hype. It provides the best aspects of a single-ply membrane including a reflective surface for improved energy efficiency, and increased protection against chemical exposure and ponding water, while the asphaltic base increases overall system waterproofing redundancy, durability and protection. The ability to be used in both new construction and recover scenarios makes a multi-ply hybrid roof an assembly choice that is here to stay.Interested in learning more about designing school rooftops?
