3 Disadvantages of a Standing Seam Metal Roof

The GAF TimberSteel™ premium metal roofing system on a house

When you're choosing the right roofing material for your home, you might rule out metal. Metal roofs are often expensive and noisy, and they can look wavy or distorted (known as oil canning). However, GAF has an alternative that allows you to get the durability and aesthetic appeal of a metal roof—without the high cost and finish concerns.

What Is a Standing Seam Metal Roof?

A standing seam metal roof is a series of mechanically attached metal panels. The attachment points, called standing seams, create a thin ridge along the outside of each panel. These seams allow the metal to expand and contract as the temperature changes without sacrificing the roof's ability to protect your home from moisture. The panels are attached to the roof structure under each seam. The fasteners don't show externally, giving the roof a consistent look.

Disadvantages of a Standing Seam Metal Roof

Standing seam metal roofs are known for their smooth aesthetic and durability. But they can have three significant downsides.

1. Price

Between the cost of metal and the need for professionally trained installers, standing seam roofs can cost two to three times as much as a standard asphalt shingle roof. The material cost depends on the metal's thickness, the requested finish, and the roof's size. Installation can also cost more because it takes specialized training to install the panels correctly. If they're not, they can experience leaks and metal expansion.

2. Noise

When it rains on a metal roof, it's noisy. Attaching the roof panels to solid wood decking and adding rigid insulation can help reduce the noise level, but you can't completely get rid of it. You might like hearing the pitter-patter of raindrops on your roof during a storm. But if you don't want this extra noise in your home, you may want to avoid a metal roof.

3. Oil Canning

Oil canning is a finish issue that occurs when the metal panels are fastened too closely together. The panels have room to expand lengthwise but not sideways. The finish begins to look like it's bubbling and continues to get wavier over time. Note that oil canning is an aesthetic issue caused by improper installation, not a material defect. The roof will continue to offer protection but will appear warped.

An Alternative to Standing Seam Metal Roofs

The GAF TimberSteel™ premium metal roofing system provides an alternative to standing seam metal roofs. Here are some features to keep in mind.

1. Lower cost

The TimberSteel system can be easier on the budget and easier to install than a traditional standing seam metal roof. While installation costs will vary by location, GAF's system offers more efficient installation than traditional standing seam panels, giving you the opportunity to save additional time and money.

2. Beauty

Instead of sacrificing looks for durability, the GAF TimberSteel system is made with an embossed vertical grain, giving the appearance of traditional roof shingles, with the strength of steel. It is specifically designed to help avoid common issues, like oil canning, that traditional metal roofs present. The TimberSteel system is also available in a variety of colors to suit your home and taste.

3. Durable finish

As the first metal shingle from GAF, the TimberSteel Premium Metal Roofing System is constructed out of GALVALUME® steel and coated with a combination of aluminum and zinc, which help to protect against corrosion. The GAF TimberSteel system also passes UL's toughest impact-resistance test — UL 2218 Class 4.

In addition, metal roof systems are completely recyclable when reaching the end of its useful life, making them a great choice for the environment.

While GAF's new metal roofing system is currently only available in select areas, you can learn more and sign up to receive information about the TimberSteel™ system, including updates on availability in your area, by visiting gaf.com/metal.

Missing Shingles on Your Roof? Here's What to Do

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?

What to Look for When Finding a Contractor

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? Find a GAF certified roofing contractor** today.*See GAF Golden Pledge Limited Warranty for complete coverage and restrictions.**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.

How GAF's VIBE ERG Supports Veteran Employees and Their Local Communities

A group of local GAF employees in Burgaw, North Carolina, is making a difference for veterans and the community as a whole. In 2024 alone, Veteran Involvement Brings Excellence (VIBE) has undertaken several initiatives to give back to Burgaw as well as all who live and work there.Bill Price, GAF production supervisor II at the Burgaw manufacturing plant, is the champion for the group. He recently sat down to discuss VIBE's latest projects and share insight into its motivations.What Is the VIBE ERG at GAF?VIBE is an employee resource group (ERG) available for all GAF employees. It focuses on the needs of veterans who work at GAF, provides a place for employees to share their experiences, and helps foster opportunities for them to give back to their communities.Each GAF plant has a VIBE group and facility leader that organizes the team. GAF leadership supports each group and its community efforts.The VIBE ERG's mission is to create a supportive environment for veterans and active duty members from all military branches. The group's core values are integrity, duty, honor, and respect. VIBE provides personal support for members and helps them manage the realities of being a veteran, such as applying for benefits.Each VIBE group can work on or be involved in whatever projects they wish. While their primary focus is to support veterans, they also strive to give back to the local communities they live and work in.VIBE Projects in BurgawThe VIBE ERG at the Burgaw plant meets regularly to discuss the activities they want to get involved in. This year, the group has participated in several projects:17 GAF-employed veterans volunteered for the second annual Habitat for Humanity veteran's build, which GAF donated roofing materials for.Team members participated in a food and clothing drive for a local women's shelter.A local veteran service officer visited the plant to help workers learn about—and gain access to—benefits and resources.In honor of Memorial Day, VIBE provided an opportunity for volunteers to place flags at veterans' tombstones at Coastal Carolina State Veterans Cemetery and Wilmington National Cemetery.That's not all the group has planned for. Future initiatives include hosting Toys for Tots at the plant, adopting a highway in honor of veterans, representing GAF at a booth for the Burgaw Blueberry Festival, and continuing to support local veterans in need.How VIBE Impacts GAF and the CommunityThe Burgaw facility, which employs about 247 people, has one of the largest veteran groups within GAF, totaling 28 members. The facility manufactures ventilation products, such as roof vents, foundation vents, turbines, and heating and cooling ductwork."The group has brought the veterans at the plant together to work toward a common goal and also given everyone the comradery they were accustomed to from when they were in the service," Price says. "I think this has had an impact not only on the employees involved but also on the plant as a whole. All of us involved enjoy being part of the team and giving back to those in need."Price notes that each project the group has been a part of has been well received. "We received many thanks from the families that were receiving assistance from the Habitat build and also from the staff at the local women's shelter during the food and clothing drive," he says. "I have no doubt that as we continue to be involved with more events within the community, it will only get better."Giving Back While Looking AheadGAF believes in giving back to its employees and the communities they work in. VIBE is just one of seven GAF ERGs making a difference in team members' lives and those most important to them.Curious to learn more about the opportunities and culture at GAF?
