Commercial Roofing Systems: 4 Key Considerations for Building Owners

Building owners have a lot to think about when selecting a roof for their commercial property. When it comes to commercial roofs, we have some information to help you understand what factors play a role in the roofing system's success, and its ability to protect the building, people and contents within it.

1. Products

There are several different types of commercial roofing systems, and each has different benefits. A roofing professional can help building owners decide between the following roofing system types depending on the unique needs of the building:

  • Single-ply: Single-ply membrane systems are the most popular commercial roofing material because single-ply is strong, durable, and provides robust protection against UV damage.

  • Liquid-applied: Liquid-applied roofing systems are also strong and durable, and they're ideal for challenging roofs with a lot of equipment and penetrations. Ensuring flashing integrity and regular membrane cleaning can help extend the life of a liquid-applied roofing system.

  • Modified-bitumen: A typical modified bitumen roofing system consists of two plies of roofing membrane. The membranes contain synthetic rubber which provides greater elongation than some other asphaltic systems. Modified-bitumen systems have a wide range of application methods, and can be hot-mopped, cold-applied, heat-welded or self-adhered.

  • Built-up roofing: Built-up roofs are the oldest of the current roofing technology, and consist of melting bricks of hot asphalt in a large metal kettle and using mops to apply that asphalt in-between a multi-ply BUR system.

It is recommended that all components of a roofing system are purchased from the same manufacturer. This helps ensure that the components are designed to work together. It also may make the system eligible for enhanced warranty or guarantee coverage from the manufacturer.

2. Energy

The rise of more stringent energy codes has increased the need for additional roof insulation and increased roof surface reflectivity. Increasing the amount of insulation in the roof and installing highly reflective roofing materials can help improve the energy efficiency of buildings.

3. Maintenance

Regular roof maintenance may be required in order to keep your manufacturer's guarantee or warranty in effect.

Maintenance programs can also help commercial building owners manage risk. Regular maintenance can help you address minor problems before they become expensive issues, which may ultimately help owners save money long-term.

Maintenance staff should perform regularly scheduled roof inspections at all locations to ensure that the roof is still in good shape. Look for dents, tears, ponding water, or other signs of damage. Roof drains should be cleared regularly to ensure that water is allowed to drain unimpeded. Regular inspections and maintenance allow potential problems to be discovered early, before they cause other damage.

Property maintenance companies and building owners can talk with manufacturers such as GAF to learn more about proper roof maintenance. Click here to get started.

4. Warranty/Guarantee

A good warranty or guarantee program is one of the top reasons commercial building owners may choose a particular roofing system. Building owners want to know that they can count on the manufacturer to address any covered issues that may arise. Many roofing manufacturers offer warranties or guarantees for building owners that have no dollar limit on covered repair expenses.

GAF offers several commercial roof system guarantees and warranties, ranging from 12 to 35 years of coverage, depending on the particular type of roofing system installed, how it is installed, and by whom. The Diamond Pledge NDL Roof Guarantee offers strong protection for commercial roofs—and for certain eligible systems, the coverage period can be extended by contracting with a GAF certified contractor* to provide maintenance throughout the roof's life. Additional requirements apply, see gaf.com for details.

With proper maintenance, the right roofing system can provide protection for years to come.


*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 have agreed that they will use GAF roofing products, and may receive benefits, such as loyalty rewards points and discounts on marketing tools from GAF for participating in the program

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.

"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.

GAF Community Matters team members repair a storm-damaged roof on a home in Puerto Rico

GAF Supports Puerto Rico Hurricane Recovery

As part of its mission to build resilient communities, GAF Community Matters has supported Puerto Rico hurricane recovery efforts through roofing material donations, roof installation trainings, and team members' hard work. This has had a multifaceted impact on the island and the people who call it home.Hurricane Maria Hit HardHurricane recovery services are needed as urgently today as they were in 2017 when Hurricane Maria struck, leaving behind 15-foot deep floodwaters, about $90 billion in damage, an estimated 2,975 lives lost, and the longest power outage in US history. For 11 months, residents waited for electricity to be fully restored.Short-term disaster relief poured in post-storm. But years after the news cycles ended, Puerto Rico still remains—metaphorically—underwater. Schools and hospitals have fallen into hurricane-related disrepair, and insufficient fixes to the power grid cause frequent blackouts and brownouts.To make matters worse, hurricane-damaged homes that weren't repaired suffer compound damage from years of subsequent storms and exposure.Puerto Ricans Stand StrongThe people of Puerto Rico are strong and proud, determined to rebuild. However, the availability of needed resources poses a considerable challenge.For many, the funds needed to repair an unsafe roof are simply out of reach. Economic opportunities are scarce, and the government is heavily in debt. The US Census Bureau reported that 42% of Puerto Rican people are in poverty.Unfortunately, lower-income Puerto Rican households most vulnerable to Hurricane Maria were also least able to recover from the financial strain of repairing storm damage. With wind speeds up to 155 mph, extensive flash flooding, and wind tunnels ripping through the mountainous terrain, homes throughout this area were no match for the Category 4 hurricane.GAF Helps Build ResilienceTo help those impacted, GAF partnered with Team Rubicon, local nongovernmental organizations, and community members through the GAF Community Matters initiative to assist in Puerto Rico hurricane recovery. Since hurricane Maria recovery efforts began in 2017, GAF has donated materials for over 500 roofs and helped install them, bringing relief and shelter to families all over the island.This work has meant more to this community than just keeping their homes dry. Mr. Alfredo—a homeowner who received a new GAF roof—said, "There is nothing more important in life than to have a place to come home to, spend quality time in, sit, and be at peace."For all of Puerto Rico's strength and perseverance, many families still live in unsafe conditions due to hurricanes. GAF can't stop storms, but it can help build resilience.To that end, in addition to installing roofs, GAF, through the GAF Community Matters initiative and GAF Roofing Academy program, provided free roof installation trainings to local organizations in vulnerable Puerto Rican communities. Educating communities on roof installation creates a greater ability to adapt and bounce back when the next storm hits.Joining the Effort for GoodIn addition to its focus on roofing innovation, GAF remains committed to partnering with local organizations to build resilience in communities across the country. Team members will continue to donate time and materials to support and strengthen communities wherever the need may be.Curious to learn more about this project and other initiatives GAF is involved in?

How GAF Contributed to Puerto Rico Hurricane Relief Efforts

Several years after Hurricane Maria struck Puerto Rico in 2017 and caused around $90 billion in damage, residents were still working to repair their homes and rebuild their communities. Subsequent storms further damaged unfixed properties and the power grid continued to suffer frequent blackouts. As a result, many families were living in unsafe conditions.In response, GAF, through our Community Matters initiative partnered with Team Rubicon and local nongovernmental organizations to provide Puerto Rico hurricane relief. GAF donated roofing materials, roof installation trainings, and hundreds of hours of volunteer labor toward the Puerto Rico hurricane relief effort. Since 2017, GAF has continued its commitment and has donated materials for over 500 roofs and helped install them all over Puerto Rico.Video TranscriptEnglish Translation: The storm came and took my home. If I would have been home during the storm, then I wouldn't be here speaking with you. [00:00:07]A lot of the homeowners either are financially short or just don't have the capabilities to do it themselves. We're able to provide the work and the labor for them and just help them out however we can.[00:00:21]It's really important to us that we are always putting the highest quality materials into these homes.Yesterday, we were at el Barrio Consejo en Guayanilla, and we were teaching ProTechos, Team Rubicon, and members of the local community how to apply GAF roof coatings. After we finished our coatings portion, we actually did a Liberty rolled roofing. GAF had donated in the past material for about 500 homes that have been done for Team Rubicon.[00:00:48]English Translation: There is nothing more important in life than to have a place to come home to, spend quality time, sit and be at peace.
