    —  What We Repair

    SEC 01 / 07

    The problems that put a commercial roof at risk.

    Flat and low-slope roofs fail in predictable ways, and most start small before becoming expensive. We repair all of them, on any roof system.

    Leaks & water intrusion

    The most common and most urgent issue. We trace the leak to its true source, which is rarely directly above the interior stain, and seal it.

    Ponding water

    Standing water that doesn't drain accelerates membrane breakdown. We address drainage and low spots, not just the symptom.

    Open seams & flashing

    Seams, parapet, curb, and penetration flashing are where flat roofs most often fail. We re-seal and re-flash to stop the path of water.

    Punctures, blisters & tears

    From foot traffic, equipment, or storms. We patch and reinforce the membrane to restore a watertight surface.

    Storm & wind damage

    Wind-lifted membrane, debris impact, and hail. We document it for insurance where applicable and restore the roof. Restoration →

    Aging & wear

    Cracking, chalking, shrinkage, and failing adhesion. We assess whether targeted repair or a recover is the smarter spend.

    —  How We Approach It

    SEC 02 / 07

    We find the real source, not just the wet spot.

    On a flat roof, water can travel a long way from where it enters to where it drips inside. Patching the visible stain often does nothing. Our approach:

    Trace it to the entry point, inspecting seams, flashings, penetrations, and drains across the field.Diagnose the cause, not just the location, so the same leak doesn't return next storm.Repair to last, with materials matched to your existing membrane system.Document everything with photos and a written scope, useful for budgets and insurance.

    —  Every Roof System

    SEC 03 / 07

    Whatever's on your building, we work on it.

    We're not tied to one membrane, so our recommendation is about what's right for your roof, not what we happen to sell. We repair every common commercial system.

    TPO & PVC

    Single-ply membranes with welded seams. TPO →

    EPDM rubber

    Proven rubber membrane on flat roofs. EPDM →

    Modified bitumen

    Multi-ply asphalt-based low-slope systems.

    Built-up (BUR)

    Traditional layered tar-and-gravel roofs.

    Metal

    Standing seam and panel roof repair & coatings.

    Shingle & steep-slope

    Commercial sloped roofs and mansards.

    —  Two Reasons To Call

    SEC 04 / 07

    Emergency now, or fix it before it fails?

    Both are smart calls. The worst option is waiting until a small problem becomes a roof replacement and a business interruption.

    Urgent

    There's an active leak right now

    Water's coming in over inventory, equipment, or a tenant space. Every hour adds damage. Our emergency line is answered around the clock and we move fast to stop it.

    Preventive

    The roof's aging and you want ahead of it

    Small issues caught early cost a fraction of an emergency or a full replacement. A free assessment tells you what needs attention now and what can wait.

    —  Why Businesses Choose Buckshot

    SEC 05 / 07

    A repair done right, with minimal disruption.

    For a business, a roof repair is risk management. We're built to protect your operations, your budget, and your liability.

    Minimal disruption

    We work around your operating hours and coordinate access and safety, so a repair doesn't shut down your business or alarm your tenants.

    Licensed & insured

    Fully licensed (WI DC-080900045, IL 104017198) and insured with liability and workers' comp, so the risk isn't on you.

    Honest scope, own crews

    We recommend the repair that solves it, not the biggest invoice, and our own crews do the work. Family-owned since 1979.

    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.

    Leaking now?

    24/7 emergency line

    For an active leak, call our 24/7 line and we move fast, often same-day, to stop the water and limit damage. For non-emergency repairs we respond to requests within 2 hours during business hours and schedule promptly.

    Very often a targeted repair is all you need, and it’s a fraction of the cost. We’ll tell you straight: if a repair solves it, that’s what we recommend. If the roof is failing across the board, we’ll show you why a recover or replacement is the smarter long-term spend. No scare tactics.

    All the common commercial systems: TPO, PVC, EPDM rubber, modified bitumen, built-up (BUR), metal, and steep-slope shingle. Because we’re not tied to one product, our recommendation is about your roof, not our inventory. See systems →

    On flat and low-slope roofs, water can travel along the deck or insulation before it drips inside, so the interior stain is rarely directly under the entry point. That’s why we trace the actual source rather than patching the visible spot, which is the difference between a fix and a repeat leak. Our approach →

    We minimize it. We work around your operating hours, coordinate access, and manage safety so your business keeps running and your tenants and customers stay protected. We lay out the plan before we start.

    Sudden storm damage is often covered, though coverage varies by policy. We document the damage for your claim and can coordinate with your insurer. Restoration services →
