— Spot It Early
SEC 01 / 07
Flashing leaks hide until they reach the ceiling. Catch any of these and a repair almost always beats a replacement.
✓Ceiling or wall discoloration around the chimney chase.
✓Ceiling or wall discoloration around the chimney chase.
✓Rust streaks on the flashing or staining running down the brick.
✓A drip that returns each storm is a flashing problem, not a fluke.
✓Lifted, split, or tar-smeared flashing that's clearly been band-aided.
✓Deteriorating mortar joints or white efflorescence on the brick.
✓A damp, musty smell in the attic near the chimney often means hidden moisture.
— Why It Keeps Leaking
SEC 02 / 07
The most common chimney "fix" is a bead of caulk over the gap. It buys a season, then the leak comes back, often worse. Here's the difference.
— What We Handle
SEC 03 / 07
From a single failed section to a full re-flash with a new roof, we cover it, and tell you straight which one your chimney needs.
When most of the flashing is sound, we reset the counter flashing, replace the failed section, and seal it correctly, no full tear-off needed.
When it's a patchwork of tar and rust, we strip it all and install new step, apron, and counter flashing from scratch.
Replacing the roof? We install all-new chimney flashing at the same time, so you never reuse old flashing under a new roof.
Water pooling behind a wide chimney? We add a cricket to divert it before it ever reaches the flashing.
— How It Works
SEC 04 / 07
One Buckshot project manager owns the job start to finish. No handoffs, no call center, no guesswork.
01
We find the actual source of the leak at the chimney, not just the stain showing up inside.
02
A clear scope: which flashing is failing and whether a cricket is needed, before you commit.
03
We strip out the old caulk, tar, and failed flashing instead of covering over it.
04
New step, apron, and counter flashing, set into the masonry and sealed the right way.
05
We confirm it's dry and hand over our workmanship warranty in writing.
— Why Not To Wait
SEC 05 / 07
A flashing leak doesn't stay small. Every storm it sits, the repair gets bigger and the bill gets larger.
Stage 1 · Weeks
Water rots the wood deck under the shingles around the chimney, a simple flashing job turns into deck repair.
Stage 2 · Months
Damp insulation and framing grow mold and lose R-value, adding cleanup and energy costs.
Stage 3 · Longer
Stained drywall, damaged framing, and a repair that now costs far more than the flashing ever would have.
— Why Buckshot
SEC 06 / 07
Earned, Not Claimed
Chimney flashing is detail work, and the wrong fix just hides the leak. That's exactly the kind of careful, accountable work a family company built since 1979 is set up to do.

Posted on Google Joy ITrustindex verifies that the original source of the review is Google. 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!Posted on Google Shelly ZieglerTrustindex verifies that the original source of the review is Google. 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.Posted on Google Amy StephensTrustindex verifies that the original source of the review is Google. 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!Posted on Google Rob AnastTrustindex verifies that the original source of the review is Google. Very customer focused company. Replaced my roof and siding after hail and wind damage 6 years ago. Second hail and damage storm this year and they are my vendor of choice again. In process now to replace my roof and siding.Posted on Google paolo masoneTrustindex verifies that the original source of the review is Google. Brad gave me a good price and the roof looks great! The roof was replaced in one day.Posted on Google Doug CooperTrustindex verifies that the original source of the review is Google. They did an excellent job! Fast, efficient and did a great job cleaning up.Posted on Google christos karampetsosTrustindex verifies that the original source of the review is Google. My family member needed a roof replacement after the recent storm in Madison , Chad came out to inspect the roof and went over the options with us. Full roof replacement and the new roof looks GREAT, they were done with in 2 days and left no mess behind which was very thankful for. Thanks !!Posted on Google Jason MontezTrustindex verifies that the original source of the review is Google. *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.

— Chimney Flashing FAQ
FAQ
Very often, yes. The chimney is one of the most common leak points on any roof because the flashing there takes the most abuse. Water can travel before it shows inside, so we trace it to the real source during the free inspection.
We won’t sell you a caulk-only “fix.” Sealant over failed flashing buys a season at most and often traps water. The lasting fix is proper metal flashing set into the masonry, which is what we install.
Step flashing is woven into the shingles along the chimney sides. Counter flashing is set into the chimney’s mortar joints and laps over the step flashing. You need both; quick fixes usually skip the counter flashing.
Yes. Reusing old flashing under a new roof is a leak waiting to happen, so we install new chimney flashing as part of any roof replacement. See roof replacement →
We handle the flashing and roofing side, including setting counter flashing into the mortar joints. If the chimney itself needs masonry rebuilding, we’ll flag it and can coordinate that work so the repair holds.
Get it looked at before it spreads. A small flashing fix now is far cheaper than the decking, insulation, and drywall damage a slow leak causes. Call (608) 909-9109 for a free inspection.
