Commercial Roofing Systems and Solutions

With the growing popularity and versatility of PVC roofing systems, GAF has responded by building a team of PVC experts to aid architects, specifiers, and the design community in project success. These highly trained and experienced professionals offer 1:1 support to help answer customers' questions and unique needs when working with PVC on roofing projects, and are here to help you!PVC, or polyvinyl chloride, is a single-ply thermoplastic roofing membrane. The material's characteristics help it thrive in particularly challenging applications. In fact, PVC roofing systems have a proven track record in the US, first introduced in the 1970s after making their debut in Germany a decade earlier.Here's a look at the benefits of PVC roofing systems as well as the guidance and support offered by the PVC experts at GAF.PVC Roofing Advantages and ApplicationsWhile several materials are available for use in roofing systems, PVC has been identified as a particularly long-lasting option. Accordingly, it's steadily grown in popularity nationwide.David Allor, senior area PVC specialist, joined the GAF team in 2022 as a PVC expert. His role was created specifically to support roof designers. Allor has an extensive background in the commercial roofing industry and extensive knowledge about PVC as a high-performance roofing solution."The industry refers to it as a very spec-driven product, and I believe what they're speaking to is a specifier's preference to work with a product that's been well established in the market and field tested," Allor shares. "It has the ability to provide protection against chemical exposure* and stand up well to challenging environments."While PVC may be a spec-driven product, it's also application-driven. Allor explains that PVC roofs may help provide protection for restaurants, food manufacturers, and packaging plants—any facility using animal fats where oils may be exhausted.* He also says that even if the building itself isn't exhausting gases, grease, or chemicals, it's important to consider the buildings and structures that surround it, as their exteriors may be subjected to exhaust that could degrade roofing systems.*Supporting the Design CommunityAs North America's largest roofing materials manufacturer, GAF has equipped teams with the resources and specialists needed to supply customers with more than just products. In recent years, the company built a solid team of PVC specialists that cover the entire US. These specialists assist customers with PVC specifications, roof system designs, and whatever else designers need to ensure successful project outcomes.Whether your project or design firm is based in the Northeast, Southeast, Southwest, Midwest, or West Coast, a PVC specialist is positioned to help. Allor explains the team of GAF PVC specialists is active in the organizations specifiers belong to, including the American Institute of Architects, the Construction Specifications Institute, and the International Institute of Building Enclosure Consultants.Allor describes the team's role as supporting the customer and connecting them to other GAF project support teams that can help. For instance, he said he called on a leading architectural design firm in the Boston area—and two months later, someone reached out for assistance with a specific project needing a tight turnaround."Literally within 12 hours of them reaching out to us, we replied and committed to three pertinent deliverables, those being a Tapered ISO Design Package, an Assembly Letter confirming all FM Requirements, and last but not least, a conference call the next day with the Building and Roofing Science team to go over three critical transitional details." Allor says.Committing to Successful Project OutcomesThe PVC specialists at GAF are focused on one goal: helping architects, specifiers, and the roofing design community achieve successful project outcomes through a high-performing PVC roofing system.

If your commercial building needs a new roof or repair, it might be time to call in a professional roofer. You might have a few contractors in your area, so knowing what questions to ask a roofer can help you find the right one for the job. In addition to requesting examples of their past work, here are eight questions to ask a roofing contractor before hiring them.1. Are You Licensed and Insured?Not all states require licensing but many do, and you'll want to see proof that the contractor is licensed in the state they'll be performing work for you.In many cases, roofing contractors who advertise their services are required to include their license number in the advertisement. Most states that require licensing have online portals where you can verify that the contractor's license is in good standing.Insurance is also important, as sometimes not all jobs go smoothly. The contractor should be covered in case an unfortunate incident occurs.2. Does Your Company Hold Manufacturer Certifications?Roofing manufacturers may offer several certification levels, helping you know what level of service and experience to expect. For instance, GAF Master Select contractors are required to complete ongoing training and be properly licensed and insured. Additionally, they must have at least $1 million in general liability insurance coverage and a satisfactory Better Business Bureau rating, among other requirements.Not every contractor can achieve certification. In fact, only 1% of roofing contractors in the US achieve the GAF Master Select status. This status means the contractor has been vetted by the manufacturer, meets strict requirements for quality control and can potentially offer enhanced warranties on roofing systems.3. Are Your Workers Certified?Many training programs and certifications are available for roofing installers, such as the National Roofing Contractors Association ProCertification® training program and the GAF CARE Contractor Training Center.You want to be sure the people working on your roof understand the proper repair and installation methods for your roofing system. Seeing what certifications they hold can confirm their roofing knowledge and familiarity with the products you're looking to install.4. Is Your Company a Member of Any Industry Associations?Membership in an industry association can demonstrate a roofing contractor's professionalism and commitment to their industry. In addition to regional, state, or national roofing associations, some commercial roofing contractors belong to associations designed for building owners and facility managers, such as the Building Owners and Managers Association or the International Facility Managers Association.If you're a member of either of these organizations, your membership list could be a good place to start your search for a commercial roofer.5. What Is Your Project Timeline and Process?The contractor should consider all aspects of your project when planning it. Ensure they'll install quality roofing systems and solutions, and share any concerns you may have—before work begins. For instance, you may be concerned about how construction may affect building occupants, including noise levels and parking. Your contractor should be able to review a plan with you that addresses these concerns.They should also give you a project timeline from start to completion and be able to explain their process, which can include:Initial site inspectionRepair or replacement recommendationsEstimate developmentProject timelinePlans to minimize disruptionsHow they'll handle and communicate unexpected issuesWarranty options6. How Do I Prepare for the Roofing Project?Determine if you need to take any steps to prepare for the project. For example, your contractor should suggest how to inform building occupants about the upcoming work and how long it will last. Also, if you have neighbors close by or share parking lots, they'll need to be notified too.Every project and building is different, so other preparations may need to happen before the project begins. Your contractor can identify any additional needs as part of their inspection and planning process. In most cases, the contractor will handle precautions—like roping off parking areas or protecting landscaping—and they should communicate that to you before your project begins.7. How Much Will the Project Cost? Are There Contingencies?Most commercial roofing contractors include the project cost in their bid package, but you should also ask about contingencies. A contingency is typically a small percentage of the total project cost that may be included to cover surprises during a roofing project, such as mold or rot. Making unexpected repairs will increase the project's cost. So, understand whether a contingency is included in your estimate so you can financially prepare.8. Do You Have a Maintenance Program for Repair Work?Once your roof has been installed, it's important to take care of it. Ask the contractor if they offer a maintenance program that includes an annual inspection of your roof. This is a great way to assess the health of your roof after a year's worth of weather. Any issues can be addressed before they turn into larger problems.By having a maintenance program in place, you can build a lasting relationship with your commercial roofing contractor and may even be able to extend your roof's warranty. If your contractor participates as a GAF Certified Maintenance Professional® you could be eligible for a 25% warranty extension with the completion of required inspections and proper documentation.Signing with a Commercial Roofing ContractorKnowing what to look for when hiring a roofer is the first step toward a successful project. Now that you know some of the questions to ask a roofer, interviewing them should be more straightforward. Their answers can help you decide if they're the right fit for your project. Keep in mind that it's wise to meet with and interview multiple commercial roofing contractors before signing a contract.Ready to take the next step? Find roofing contractors certified by GAF* in your area and schedule a time to talk about the commercial work you need completed.*Contractors enrolled in GAF certification programs are not employees or agents of GAF, and GAF does not control or otherwise supervise these independent businesses.

Historically, commercial skylights have gotten a bad rap. "The old joke was: 'if it's not leaking now, it will be soon,'" says Brian Grohe, a 13-year vet of the skylight industry and a commercial sales manager at industry leader VELUX. Fortunately, technology has changed that old tune for the better, turning commercial skylights into a golden opportunity for roofing contractors.Thanks to revolutionized frame designs, glazing, and water management strategies, installing these rays of light in a roof provides added value to customers while increasing project revenue. Plus, it's now possible to streamline skylight ordering, delivery, and warranty/guarantee services through your roofing manufacturer, which can help save time and money.Benefits of Commercial Skylights"The skylight of the past is not the skylight of the present," Brian explains. "The aesthetic and practical benefits can improve a building's space, increase revenue, and positively impact resale value." Here are just some of the perks of incorporating natural overhead light into your commercial roofing repertoire.Contractor BenefitsExpand work opportunities: Replacement work makes up a large part of the commercial skylight industry, according to Brian. This presents a tremendous service opportunity for contractors if they can identify and repair or replace an older skylight that is sun-damaged, broken, or leaking. "Solve a building owner's problem for them," suggests Brian, "and you'll expand your work while adding value for the customer."Increase revenue potential: Adding this ancillary product into a project proposal provides aesthetic and financial benefits to the customer, and increased revenue potential for the contractor.Benefits for Building OwnersSave money: Explain to customers how a skylight can reduce electrical consumption by harnessing sunlight. In fact, a daylighting strategy can reduce the need for energy-consuming electric lighting by 20% to 80%. This saves on costs for building owners.*Improve tenant or employee well-being: Exposure to natural light can have a positive impact on the health and well-being of a space. This can increase employee productivity, work satisfaction, and overall wellness.Boost building value: Enhancing the architecture and natural light in a space can improve the building's appearance and increase potential resale value.Commercial Skylight TypesCommercial skylights come in a range of shapes — dome, pyramid, vault, low-profile, etc. There are also different functionalities, such as vented or fixed, which describe whether the skylight provides ventilation. All of these options fall into two main categories: glass and plastic.A glass skylight is often an architectural consideration, Brian says. "[They] accentuate designs of the building and provide a stunning view."Most commercial skylight projects like those in "industrial buildings, retail, some office spaces, and places like school gyms use the plastic unit skylight," says Brian. Fortunately, "these are already in a roofer's wheelhouse, because it's no different — from a flashing standpoint — than any other roof penetration."Unlike older plastic skylight materials that didn't provide much UV protection, prismatic polycarbonate is now the industry standard. A modern plastic skylight can offer high-clarity, excellent thermal insulation, impact resistance, UV protection, and long-term high light transmission.Choosing the Right Commercial SkylightTake these factors into consideration when navigating skylight brand and style selection for a project:Customer and building needs: A project in a storm-prone region may benefit most from a hurricane-rated skylight, while another project focused on maximizing energy efficiency would benefit from sun-harvesting industrial warehouse skylights. For example, VELUX offers the Dynamic Dome, engineered to harvest more early morning and late afternoon daylight than its competitors and allow a building's lights to remain off for nearly an extra hour per day.Proprietary skylight designs: Proprietary skylight offerings from a company typically provide "stronger impact resistance and better UV resistance long-term," says Brian. Often, proprietary designs last longer for the building owner and are safer for roofers.Warranty/Guarantee coverage: Carefully research what a warranty covers when selecting the commercial skylight you'll use for a project. "Some skylight manufacturers have very limited warranties," Brian notes. GAF and VELUX offer a new approach — when purchased through GAF, VELUX skylights are eligible for up to 20-years of coverage under GAF NDL (no dollar limit) guarantees.**Combining Roof and Skylight WarrantiesRoofers can make a project easier and get a stronger warranty by going through one manufacturer and distributor for both their roof and skylight needs. GAF and VELUX have teamed up to provide this seamless service. This alliance "streamlines skylight ordering, freight coordination, warranty/guarantee registration, and any manufacturer claims because it's one manufacturer and one distributor handling the project needs," explains Brian.For roofers, the project makes it easier from a purchasing and ordering standpoint: "All order management and freight coordination happen through one source," says Brian. Consolidating roofing and skylight needs also streamlines the delivery of materials coming to a job site.This also holds advantages during the life of the roof. "You're getting a warranty that's tied into the roof system," says Brian. "This means that if there is a problem with a skylight after construction is completed, the contractor or building owner doesn't have to find out who the manufacturer is and submit a separate claim — they can handle claims through GAF. Also, the timing of the roof guarantees and skylight warranties will match, meaning there are no gaps in coverage."Want to learn more about expanding your roofing services while upgrading your commercial roofing projects?
