    The part you can’t see

    What’s under your shingles?

    Roofs that look fine from the ground can hide rotted roof decking. Flip to the deck to see what a tear-off reveals.

    The layers shown are illustrative; Buckshot inspects your real decking on the bare deck during tear-off.

    Warning signs

    Roof decking warning signs worth an inspection.

    Rotted roof decking usually hides until tear-off, but these six clues are worth an inspection. Our guide covers when to replace roof decking.

    A wavy or dipping roofline

    A roofline that dips between rafters shows roof decking flexing where the wood has gone soft.

    Soft spots underfoot

    Roof decking that feels spongy under a roofer’s feet during inspection has usually rotted or delaminated.

    Water stains in the attic

    Dark stains on the underside of the roof deck or rafters point to old leaks.

    Daylight through the boards

    Light showing through the roof boards in the attic means the decking has gaps or has rotted through.

    A damp, musty smell

    A musty smell or mold in the attic signals trapped moisture, which rots roof decking over time.

    Lifting or rippling shingles

    Shingles that lift or ripple can signal an uneven or failing roof deck that no longer holds them flat.

    How it’s priced

    How roof decking replacement is priced.

    Roof decking replacement is priced per sheet, once tear-off shows how much sheathing has rotted.

    A separate line item

    Decking appears as its own estimate line, since the amount is unknown until tear-off.

    Priced per sheet

    Buckshot prices decking per sheet of plywood or OSB, so your cost tracks the wood replaced.

    We show you first

    Buckshot shows you every rotted sheet before swapping it, so you see what you pay for.

    You approve it

    Decking work starts only with your approval, and a sound deck adds nothing to your bill.

    Buckshot works with any insurance carrier, and on a covered insurance claim you typically pay only your deductible.

    The water barrier

    Roof decking first, then two water barriers.

    Buckshot covers sound roof decking with two water barriers before any shingle goes on.

    Code-compliant decking

    Buckshot replaces rotted sheathing with plywood or OSB in the common 7/16 or 1/2 inch thicknesses, adding H-clips where spans require them.

    Synthetic underlayment

    Buckshot rolls synthetic underlayment across the full roof field as a second barrier if water gets past the shingles.

    Ice & water shield

    Self-adhering ice and water shield seals the eaves, valleys and penetrations, where ice dams and wind-driven rain start leaks.

    Full bare-deck inspection

    Buckshot builds every new roof on sound decking.

    Shingle nails need sound roof decking to hold, so rotted sheets shorten the life of a new roof.

    Buckshot tears off to the bare deck, inspects every square foot and replaces failed sheathing before anything new goes on. Our own crews handle the tear-off, decking replacement and shingles.

    How it goes on

    How roof decking replacement works.

    Buckshot replaces roof decking mid-reroof, after tear-off and before the new shingles.

    Tear off to the bare deck. Our crew strips the old shingles and underlayment to the sheathing, exposing the whole roof deck.
    Inspect & replace bad sheathing. Buckshot marks each soft or rotted sheet, shows it to you and nails code-compliant plywood or OSB in its place.
    Seal the deck. Synthetic underlayment covers the field, and ice and water shield seals the eaves, valleys and penetrations.
    Shingles & a walkthrough. New shingles go on over the sealed deck, and Buckshot walks the finished roof with you.

    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!

    Frequently asked

    Roof decking replacement questions, answered.

    Roof decking is the plywood or OSB sheathing nailed to your rafters, and it holds the underlayment, flashing and shingles. Buckshot’s guide explains roof decking and when to replace it.

    Roof decking usually needs replacing because hidden rot from old leaks, trapped attic moisture or delamination has softened the wood. Older homes with skip sheathing, the spaced boards once used under wood shakes, also need solid decking before asphalt shingles.

    Before tear-off, a sagging roof deck, soft spots, attic stains or daylight through the boards are the main clues. Much of the rot stays hidden until the old roof is off, so Buckshot confirms decking condition on the bare deck.

    Yes, every reroof needs underlayment, the water-resistant layer between the roof deck and shingles. Buckshot runs synthetic underlayment across the whole roof field as a backup barrier.

    Ice and water shield is a self-adhering membrane that seals the eaves, valleys and penetrations against ice dams and wind-driven rain. In Wisconsin’s freeze-thaw climate, those are the spots most likely to leak.

    Roof decking replacement cost depends mainly on how many sheets have rotted, plus sheathing thickness and any rafter repair. Buckshot prices it per sheet as a separate estimate line and shows you the rotted wood first.

    Plywood and OSB both make code-compliant roof decking when the panels are rated for your rafter spacing. Plywood generally tolerates wetting better, while OSB usually costs less, and 7/16 or 1/2 inch panels are common on homes.

    Yes, small sections of roof decking can be replaced during a roof repair by removing the shingles over the damaged area. Widespread rot is usually handled during a full roof replacement, when Buckshot can inspect the whole bare deck.
