    —  Why EPDM For Commercial

    SEC 01 / 07

    Proven, simple, and built to last.

    EPDM (ethylene propylene diene monomer) is a synthetic rubber membrane that's been protecting commercial flat roofs for over 50 years. Its appeal is straightforward: it's durable, dependable, and cost-effective. Here's what that means for your building.

    Decades of proven life

    EPDM has one of the longest track records of any single-ply membrane. Properly installed, it delivers a long, dependable commercial service life.

    Weather & UV resistant

    Rubber stands up to UV, ozone, temperature swings, and weathering exceptionally well, ideal for the freeze-thaw cycles of the Midwest.

    Flexible & forgiving

    EPDM stays flexible across temperature extremes, expanding and contracting with the building without cracking or becoming brittle.

    Cost-effective

    EPDM is often among the most economical commercial membranes per square foot, especially attractive on large roof areas.

    Simple to maintain & repair

    Its long history means repairs are well understood and straightforward, easy to patch and service rather than replace wholesale.

    Installed right, by us

    A flat roof depends on the install. Our own commercial crews, never subcontracted, detail every seam and penetration to spec.

    —  EPDM vs. TPO

    SEC 02 / 07

    Which membrane is right for your roof?

    EPDM and TPO are the two leading single-ply systems, and the right one depends on your building, climate priorities, and budget. Here's an honest comparison.

    —  What An EPDM Install Includes

    SEC 03 / 07

    A complete system, not just a sheet of rubber.

    Tear-off or prep of the existing roof, with substrate and decking inspection and repair as needed.Insulation & cover board selected for your building's thermal and structural needs.EPDM membrane installed ballasted, fully adhered, or mechanically fastened to suit the building.Seams & flashings detailed at parapets, curbs, drains, and penetrations, the points where flat roofs usually fail.Cleanup & walkthrough, with the site left clean and the work documented for your records and warranty.

    —  Repair · Recover · Replace

    SEC 04 / 07

    Not every roof needs a full tear-off.

    A full replacement isn't always the answer, and we'll tell you straight which makes sense for your building and budget. 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 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 EPDM system for a fresh service life.

    EPDM has a strong longevity track record, it’s been in commercial use for over 50 years. Actual service life depends on the membrane, installation quality, and maintenance. We’ll give you realistic expectations for your specific building and system.

    Both are excellent single-ply systems. EPDM (usually black) has the longest track record and often the lowest cost, strong in cold climates. TPO has a reflective white surface that can lower cooling costs and uses heat-welded seams. The best fit depends on your building and priorities. See the comparison → or view TPO →

    Often, yes, a recover installs a new membrane 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 right depends on what’s there, which 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.
