    —  Why TPO For Commercial

    SEC 01 / 07

    The flat-roof workhorse, for good reason.

    TPO (thermoplastic polyolefin) has become the default single-ply membrane for commercial flat and low-slope roofs because it balances performance and cost better than the alternatives. Here's what that means for your building.

    Energy efficient

    TPO's reflective white surface bounces solar heat instead of absorbing it, which can lower cooling costs on a large flat roof through the summer.

    Watertight seams

    TPO seams are hot-air welded, not just taped or glued, creating a continuous, monolithic membrane that's far more leak-resistant over time.

    Durable & resistant

    Resists punctures, tears, UV, and chemical exposure, holding up to foot traffic, rooftop equipment, and Midwest weather swings.

    Cost-effective

    TPO typically delivers strong value versus other commercial membranes, competitive material cost with a long, dependable service life.

    Low maintenance

    A properly installed TPO roof needs minimal upkeep, mostly periodic inspections and keeping drains clear, no constant patching.

    Installed right, by us

    A flat roof lives or dies on the install. Our own commercial crews, never subcontracted, weld every seam and detail to spec.

    —  Repair · Recover · Replace

    SEC 02 / 07

    Not every roof needs to be torn off.

    A full replacement isn't always the answer, and we'll tell you straight which makes sense for your building and budget. There are three paths.

    Repair

    Targeted fixes to seams, flashings, punctures, and drains to stop leaks and extend the life of a roof that's otherwise sound.

    Recover

    Installing a new TPO membrane over the existing roof where the structure and decking allow, avoiding a full tear-off and its cost and disruption.

    Replace

    Full tear-off to the deck, inspection and repair of the substrate, new insulation, and a complete new TPO system for a fresh service life.

    —  What A TPO Install Includes

    TPO (thermoplastic polyolefin) is a single-ply membrane for commercial flat and low-slope roofs. It’s known for a reflective, energy-efficient surface and hot-air-welded seams that create a continuous, watertight roof. It’s the most widely installed commercial membrane today. Why businesses choose it →

    A properly installed TPO roof typically delivers a long commercial service life, with the membrane thickness, insulation, install quality, and maintenance all affecting longevity. We’ll talk through realistic expectations for your specific building and the system we’d recommend.

    Often, yes, a recover installs new TPO over the existing roof where the deck is sound and code allows, saving the cost and disruption of a full tear-off. Whether it’s the right call depends on the condition of what’s there, which is exactly what the free assessment determines. Repair vs recover vs replace →

    When the big storms came through the Madison-area in April 2026, I immediately started looking for a reputable roofer—who also understood the importance of weather-resistant materials that can withstand hail and wind. It didn’t take me long to find Brad from BCG. We had damage that needed to be repaired before the next round of storms came through later that day and Brad had a crew out within hours. Our neighbors also had damage, and when their roofing company didn’t show up, Brad and his crew also took on fixing their damage on the spot. The contracting process was done over email and we were able to clearly understand all of the options available to us. On the day of install, the crew was efficient and fast with their work. But also, mistakes can happen. And what matters to us is not that there’s perfection (because that’s not realistic), but how a contractor deals with a mistake. As they were taking down the tarps when they were finished with the roof, one of our lights next to the garage broke. Brad helped find a replacement online and had it shipped directly to our house! Such great service! All in all, we were very happy with Brad and the service we received from him and BCG. We’ve since recommended their services to several of our friends and neighbors who also had storm damage. While I hope we won’t have to do that again for a long time, we would work with BCG again in a heartbeat!

    I am extremely pleased with the service Matt Walmer from Buckshot General Contracting (BGC) provided for me during the hailstorm damage in Madison in April. I had just switched insurance companies one year ago and was worried about how much they would cover. Matt assured me everything would be taken care of and had nothing to worry about. True to his word he immediately answered phone calls during off hours even when he was with daughter at volleyball and answering texts in seconds Matt met up with assessor and arrived 20 minutes early. During roof replacement he stopped in 3 times to check the progress and next day he came back to do a walk around to make sure the cleanup was to his standards. I have been so blessed to work with Matt at BGC as my contractor as everything went so smoothly. No problems with my insurance company and I was the first one on my block to get my roof done. I also was telling Matt about some of my neighbors having problems with their insurance and he was willing to look at their paperwork and giving them advice on how to deal with them. I can proudly say I announced to them how good Matt was and gave them his card. Thank you so much Matt for your excellent service and being a great representative for Buckshot General Contracting. These days days it’s hard to find a business that is 100% committed to making sure the customer is their #1 concern. Going to be doing more work and sticking with them as I know it will be top quality.

    We contacted BGC after storm damage and had them completely re-roof and re-side our house, garage, and shed. The entire process was incredibly smooth from start to finish. They were easy to work with, handled all the details, and made what could have been a stressful situation completely worry-free. Our contact, Jayce Kirkland, was outstanding. His professionalism, communication, and courteous demeanor were truly a breath of fresh air. He took care of everything for us and made sure the project stayed on track every step of the way. We couldn’t be happier with the experience and have and would highly recommend BGC to anyone needing roofing or siding work!

    *update* number 2 I have been through about 4 different people now to get my issue fixed. They came and fixed the side that was leaking. The contractor that came out confirmed the siding wasnt installed properly and put in some flashing to fix the issue. Since it wasnt installed right i wanted the rest of the house done to prevent other issues and the company agreed to do that. Still not done and now im dealing with yet another person who has not contacted me to resolve my issue. Told them when this job was completed i wanted a new patio door as well to get the last year of the energy credit. Crickets. I have been very patient, but am beyond frustrated at this point. *update* After posting i was contacted regarding my review. Turns out the reason i wasn’t contacted was because my salesman is no longer with the company and never responded to tell me that when i called him (his number was still correct at the time of the call). I had a rep come to my home and immediately discuss solutions to the issue. Everything was done properly on my home, its just one of those things no one could foresee. I am beyond happy with the speed things are moving once i was contacted. Already making plans for additional work needed next season. Had windows and siding done. The windows crew was fantastic. Personable as well as professional. Siding crew was also great. My issue comes with the after care. My basement was leaking during rains. It also leaked running the sprinkler for new grass. Contacted my salesman and never heard back. Been probably a month? Had a contractor friend of mine come look and the issue was the siding wasnt ran low enough (or a piece of flashing would have worked as well) to stop water from coming through the basement from under the sill plate. Id have even paid to have it corrected, but no call. My issue is a simple one, but the aftercare deserves a one. The total score is because their crews were great. The people in admin simply need to be better. I had to remove foam that was trafficking water in and will be using flex seal to create a barrier since no call was made back. Update as of april, 2026. After some frustrating back and forth one of their contractors came our and looked at my situation late summer of 2025. Confirmed the siding wasnt done properly and installed flashing where the leak was and i haven’t had an issue since. Despite the numerous tornados weve had. With that said, Fall of 2025 i told them (after being informed the siding wasn’t done properly by their guy) i told them while the basement no longer seems to leak, i want the rest of the house covered with that flashing incase their are other problems. i dont want to refinish my basement to discover issues. The “salesman” essentially accused me of only wanting free things and after him explaining to me how awesome he was and that i was wrong, i stopped the phone call. The subcontractors they hire are overall solid, but some of the staff have made the company unusable for me. Just be cautious if you use them. Communication is great… until they get your money.
