Questions to Ask a Roofer for Your Commercial Roof Project

November 08, 2023

Two roofing contractors on a commercial roof at work

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 inspection
Repair or replacement recommendations
Estimate development
Project timeline
Plans to minimize disruptions
How they'll handle and communicate unexpected issues
Warranty options

6. 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 Contractor

Knowing 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.

About the Author

Karen L Edwards

Karen L. Edwards is a freelance writer for the construction industry and has a passion for roofing, having worked in the industry for 20 years.

The roofing industry has long been a competitive space for contractors, but that healthy competition has helped drive innovation and lift up independently-owned businesses across the country. BYLTup, Inc. is one such business, and CEO Trevor Leeds is committed to elevating the greater roofing industry through everything his company does.After many years in roofing, Trevor partnered with his brother, Brady Woodside, in 2022 and co-found BYLTup, Inc. in Southern California. The pair started from scratch with a blank slate, allowing them to create a culture and brand experience that raises the industry bar, which is important to them.Trevor knew GAF would be a part of their success from the start. He experienced GAF-certified contractors'* support through his previous company and knew the organization's vision and innovation would be key to building the business.Enhancing Roofing Professionalism and SafetyTrevor is passionate about the roofing industry and believes everyone—from manufacturers and distributors to the contractors performing the installations—should work together to create a professional and positive customer experience. Even more importantly, Trevor advocates for the industry's employees and their experiences; safety is an area he wants more people to consider."We need to be making sure that we are taking care of employee safety," Trevor says. "Everyone should be focused on that. Everyone should be concerned about their employees going home safe and sound every single night. When an accident happens in the industry, it's devastating to the business owner and the individual, but it impacts the industry too. We all feel that in some form or fashion."Guiding the Next Generation through GAF Roofing AcademyTrevor's concern for employees and the industry's future led to his involvement in the GAF Roofing Academy. While he didn't have an immediate need for labor in his business, he recognized that taking action now could contribute to building a pipeline of skilled workers that would benefit the roofing industry as a whole.Trevor observed the pool of talent and skilled workers dwindling during his time in roofing. "You have the baby boomer generation that is retiring and a younger generation that wants to get into tech and doesn't want to get into the trades," he notes. "We've got to be able to hire and attract young talent back into the industry or we're all going to suffer."Training Students at the SoCal Roofing AcademyTrevor first learned about the GAF Roofing Academy at a regional conference and stepped up to assist. His company was involved in the first SoCal Roofing Academy, which had three tracks: residential roofing, commercial roofing, and sales training. BYLTup hosted the training's residential portion, and Trevor was impressed by the students' interest and engagement."I was blown away at how engaged they were. GAF had certainly done a very good job screening and prepping these individuals coming in, but they were green," he says. "The trainer was fantastic. The students were shingling after three days."Once the groups completed the tracks, they were brought back together for their graduation ceremony, which was a life-changing experience for many. "I realized that many of these people had probably never been recognized like this before," Trevor says. "They were very proud, holding their certificates and sending photos to their families."Making an Unexpected Hire at BYLTupJust before hosting the SoCal Roofing Academy, GAF Roofing Academy Operations Manager Erick Osuna reached out to Trevor and shared recent graduate Jose Navarro's resume. Jose had completed the commercial roofing training program and stood out to Erick, so he connected with Trevor about possibly hiring him."At that time, I wasn't looking for someone on the commercial roofing side. We weren't really expanding that crew, but we were looking for a production role," Trevor shares. "Long story short, we loved him. He was going to be a great fit for the company, and we hired him as our assistant production manager."Jose excelled on the job. BYLTup quickly moved him into a full production manager role, hiring an assistant to work with him. Trevor says Jose was a great hire. "He's young, he's hungry, he wants to learn. I've never seen another individual in the industry that just wants to learn roofing, and he's a sponge."Committing to Supporting GAF Roofing AcademyTrevor has seen the caliber of students attending and graduating from the GAF Roofing Academy, inspiring his commitment to support ongoing trainings. "I was pleasantly surprised at the overall outcome of the [Roofing Academy] event," he notes. "It encouraged me to the point that I said, 'I want to do this, whether we benefit from it or not, I want to support this at least twice a year, and we want to get more contractors involved in it.'"Want to get involved in supporting the future of the roofing industry?

A newly renovated basketball court at Chambers Park Community Center in Kissimmee, Florida, is a slam dunk for local children and families. GAF is proud to have partnered with the Orlando Magic, AdventHealth, and the city of Kissimmee to make this community's hoop dreams come true.The Chambers Park Community Center is a focal point of the Kissimmee community. The facility offers after-school programs, community events, and camps. It also features a popular neighborhood playground and basketball court where friends and families gather.The collaborative work involved in upgrading the sports court—which reopened on January 10, 2024—is just one example of how the GAF Community Matters program supports and celebrates neighborhoods nationwide.Renovating the Court's Coating and DesignThe inspiration for this project came from wanting to enhance the quality of life for the residents of Kissimmee and provide a safe, vibrant place for families to play outdoors. GAF understands the importance of building resilient communities, so the company donated cutting-edge materials and covered the cost of installation labor to ensure the Chambers Park Community Center's new sports court was a perfect outdoor place to play. To make the asphalt court as safe and durable as possible, GAF used StreetBond® solar-reflective, durable pavement coating with Invisible Shade™. The product can help reduce pavement surface temperatures by an average of 10°F while also helping to protect the pavement from premature degradation due to heat and UV rays.In areas where heat collects, also known as "urban heat islands," there tend to be few trees and minimal shady vegetation, so blacktops and hard surfaces—including parking lots, roadways, concrete recreation areas, and roofs—absorb and release heat well into the evening. Over time, these excess temperatures may contribute to heat-related health effects and negatively impact quality of life for local area residents. This wasn't the first time GAF deployed pioneering cooling strategies to enhance a community's experience. As part of the GAF Cool Community project in Pacoima, California, StreetBond® was used to help diminish urban heat island effects. GAF quickly completed the work in Kissimmee and the facility was opened to the public shortly afterward. The sports court's vibrant design uses custom-made colors inspired by the blue retro logo honoring the Orlando Magic's 35th anniversary court.Celebrating the Court's OpeningCurrent and former Orlando Magic players and Kissimmee's Mayor celebrated the court's unveiling. Team mascot STUFF the Magic Dragon joined the festivities to the crowd's delight.Sixty youth from the Chambers Park Community Center after-school program also attended the court's reopening. The students were thrilled to join in a fast-paced basketball skills clinic. The newly launched court was their chance to meet their sports heroes up close, take photos with them, and enjoy their new playground.Investing in Communities of the FutureThe Chambers Park Community Center's sports court is an important gathering space where youth and their families can safely play, build relationships, and develop their skills.With this project, the GAF Community Matters initiative continues its longstanding partnership in neighborhoods across the country. GAF is committed to making a positive difference by offering roofing expertise, resources, and products to help build more resilient communities.Providing safe, high-quality sports courts where residents can gather helps build resilient communities while promoting active, healthy lifestyles—and GAF is proud to play a role.

The Louisiana coast has seen several severe weather events in the last decade, which has made it difficult for many people to rebuild their homes and prepare for future storms. This was the case for the Atakapa Ishak Chawasha tribe, a small community accessible only by boat.The group Rebuilding Together New Orleans recognized the impact a joint effort could have on the region. Together with the GAF Community Matters initiative, and roofing contractor Sunbelt Roofs, the group collaborated with the Atakapa Ishak Chawasha tribe to replace five hurricane-damaged roofs in the tribe's coastal Louisiana homeland.Sowing ResilienceThe week-long roof rebuilding initiative was part of the GAF Community Matters commitment to repair or replace 500 roofs throughout the Gulf region. The goal was to further strengthen and empower the resilience of the families, shelters, and livelihoods of the coastal Atakapa Ishak Chawasha tribe.The Timberline HDZ® RoofCycle™ Series Shingle, which is made with recycled material, was used to protect these homes.Adapting Environmentally"We are stewards of the environment," said Rosina Philippe, a tribal elder of the Atakapa Ishak Chawasha tribe, as she spoke with GAF during the week-long rebuilding initiative. Over a millennium, the tribe has resided in the region, finding all it needs to feed and sustain itself from the environment.However, man-made conditions have significantly impacted the tribe's way of life. The once-forested coastal region is now a salt marsh area, devoid of fresh water and trees, due to levees along the Mississippi River and canals cut through the coastal landscape.These changes have made it "more of a challenge to find the food and plants and medicines that we depend on for our livelihood. But we have been finding them, propagating them, and sharing them with other tribes," said Philippe. "Our way is to accept the natural processes, not change them."Fortifying against Unpredictable WeatherIn addition to the tribe's changing landscape, "what we're dealing with is the unpredictability of the weather," said Philippe. Climate change can cause dramatic temperature swings, which can impact everything from the life cycle of the tribe's crops to the protection of its homes.Situated at the southeasternmost lands of Plaquemines Parish, fingerlike marshland trails out into the Gulf. The homes in the Atakapa Ishak Chawasha community are built on stilts along these watery paths and are accessible only by boat. These homes are often the first line of impact with hurricanes that rip through the Gulf of Mexico.Hurricane Ida—the fifth most expensive hurricane in US history—dealt the water-based community a devastating blow. For nearly two years, the hurricane's impact on tribal homes compounded with each subsequent storm because there wasn't an opportunity to repair its damage.Partnering for StrengthFortunately, through collaborative efforts between the Atakapa Ishak Chawasha, Rebuilding Together New Orleans, GAF, and Sunbelt Roofs, the opportunity to build tribal community resilience through new roofs became available. Bringing in roofing materials and roofers by boat, the Sunbelt Roofs team removed the storm- and hurricane-damaged roofs, repaired roof decking as needed, and installed new GAF roofing systems on the five homes.The roofing materials installed are designed to protect against volatile weather like hurricanes. To provide long-lasting protection against leaks and wind-driven rain, Sunbelt Roofs installed StormGuard® Film-Surfaced Leak Barrier and FeltBuster® Synthetic Roofing Felt. To help prevent shingle blow-off due to high-speed winds, Sunbelt Roofs installed Pro-Start® Starter Strip Shingles.The Timberline HDZ® RoofCycle™ Series shingles that were installed have Dura Grip™ Adhesive, which provides advanced protection from shingle blow-off and wind-driven water creating leaks or water damage.Building Communities TogetherThe initiative with the Atakapa Ishak Chawasha tribe is part of a comprehensive $25 million GAF commitment through 2025 to leverage roofing expertise, resources, and products to help support and empower resilient communities' fundamental needs. Through grants, in-kind donations, and hands-on support, GAF Community Matters is partnering with area organizations that know their communities' needs best.In the Gulf region, GAF partnered with organizations such as Rebuilding Together New Orleans, SBP, Good360, Habitat for Humanity, and Team Rubicon to rebuild or repair 500 Gulf region roofs, train a skilled workforce, and empower communities hard-hit by severe weather.Moving ForwardDespite the challenges of climate change and the changes in their physical landscape, Philippe said, "We still live a rich life here." As the environment changes, the tribe adapts, a demonstration of its resiliency. "These are the new norms that we are having to learn and document and chronicle, this is the information we'll have to pass onto our future generations so that they can continue to inhabit this area," she explained.To learn more about the resiliency work at GAF or to get involved, explore the GAF Community Matters initiative.
