    —  What We Repair

    SEC 01 / 07

    Common commercial roof problems Buckshot repairs.

    Flat and low-slope commercial roofs fail at predictable points, and Buckshot repairs each one on any roof system.

    ✓Leaks & water intrusion

    Water often enters far from the interior stain, so Buckshot traces each leak to its source.

    ✓Ponding water & drains

    Ponding, typically water still standing 48 hours after rain, speeds membrane breakdown, so Buckshot clears drains and corrects low spots.

    ✓Open seams & flashing

    Seams, pitch pockets and base flashing at curbs fail most often, so Buckshot re-seals and re-flashes them.

    ✓Punctures, blisters & tears

    Foot traffic punctures membranes and trapped moisture raises blisters, so Buckshot patches and reinforces the surface.

    ✓Storm & wind damage

    Buckshot documents wind-lifted membrane, hail bruising and debris punctures for your insurance claim, then repairs the roof.

    ✓Aging & worn membranes

    Cracking, shrinkage and failing adhesion mark an aging membrane, so Buckshot weighs targeted repair against a recover.

    —  How We Trace Leaks

    SEC 02 / 07

    Finding the source of a commercial roof leak.

    A commercial roof leak stops when its entry point is sealed, and that point often sits far from the interior stain. Buckshot finds that point in four steps.

    Trace the entry point by checking seams, base flashing, pitch pockets and drains.Diagnose the cause, where an infrared survey or core cut can reveal wet insulation.Repair to last with materials matched to your existing membrane system.Document everything with photos and a written scope for your budget and insurance.

    —  Two Reasons To Call

    SEC 04 / 07

    Emergency now, or fix it before it fails?

    Calling early keeps a small commercial roof problem from becoming a replacement and a business interruption.

    Urgent

    ✓There's an active leak right now

    When water reaches inventory, equipment or a tenant space, every hour adds damage. Call the 24/7 line at (608) 909-9109 and a crew moves fast to stop the water.

    Preventive

    ✓Your roof is aging and needs a plan

    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.

    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!
