TPO by GAF
TPO flat roofing stands for “thermoplastic polyolefin.” TPO is a single-ply roofing material, manufactured in sheets that are 10, 12, or 20 feet wide. These single-ply sheets are conveniently rolled up and taken to the commercial property for installation. TPO naturally reflects UV rays from the sun.
Benefits:
- Fire resistant
- Plenty of insulation options to choose from
- Reflects away heat, saving money on energy bills

Planning and Installation process
How we prepare the roof to prevent leaks
4 Step Installation Process
At GenSun Roofing, we are committed to getting commercial roofing projects done right the first time. You should never have to wait on unreliable communication or shady pricing structures when it’s time to replace or repair your commercial roof. Our team has implemented a four-step process so that you know exactly what to expect when it’s time for your flat roof installation.
Step 1
At the first signs of an aging flat roof, reach out to us right away. You will schedule a free inspection and estimate, during which we will use innovative technology to document your roof’s condition and any damage. Then, we will offer a detailed explanation of what we found and offer our recommendations for repairs or replacement. You will receive a detailed quote for the work we recommend.
Step 2
After you review our findings, estimate, and recommendations, and officially decide to hire us for the project, we will send over an agreement that details the full scope of the work that will be done. We will work with you to schedule a convenient time to begin the installation process. We always maintain close communication and let you know right away if work needs to be rescheduled due to inclement weather.
Step 3
The job site supervisor will be your point of contact on installation day. A skilled, professionally-trained team of flat roof installers will be on-site on time to repair or replace your roof. For smaller commercial buildings, installation can be completed in as little as 5 days. In terms of larger buildings, flat roof installation can take up to 2 to 3 weeks.
We keep a digital photo record of every step of the installation process. Once the work is done, the site supervisor will complete an in-depth final inspection and clean up all debris. Our clean-up process is so reliable that you won’t even know we were there!
Step 4
It’s our goal that every customer is completely satisfied with their new commercial roof, so we strive to always get our projects done right the first time. If for any reason you’re unhappy with the result, that means we’re unhappy, too. Always feel free to reach out, and we’ll be sure to make the situation right.
