Beloit’s Post-War Housing Boom
Beloit has some of the oldest housing in the Stateline. Census estimates for 2020 to 2024 put the median home at 1957. The biggest building stretch came right after the war: about 28% of the city’s homes date from 1940 through 1959, more than in any later twenty-year span. Another 27% are older still, including many of the two-stories near Beloit College and downtown.
A house from the 1940s or 1950s has likely been reroofed more than once, and the last roof may have gone right over the one before it. That history shapes everything about the next replacement, from what is under the shingles to how the attic breathes.
Bedrooms Under the Roof
If your Beloit house has bedrooms tucked under the roof, with short knee walls on each side, the roof is working harder than it looks. There is very little attic space to vent, so heat and moisture build right under the shingles. That is a common reason roofs on these houses age early and grow ice at the eaves.
When we replace a roof like that, we look at how air gets in low and out high, and we add venting where the framing allows it. It will not turn a hot upstairs into a basement, but steady airflow helps the new shingles last and helps keep ice off the edges. See attic ventilation.
Tear-Off on an Older Beloit Roof
Every old layer comes off, down to the deck. On houses this age the deck is often wood planks instead of plywood, and the gaps between boards, old nail holes and soft spots at the eaves all show up once the shingles are gone. New shingles need a solid, even surface to lie flat and hold their nails. We replace bad boards, and where the planks are too rough or gapped, we talk with you about new sheathing over them. The per sheet price is in your written estimate before we start, and you get photos of what we replaced.
Chimneys get a close look too. Many older Beloit chimneys have been flashed and patched several times. New flashing goes on with the new roof, and if the brick itself looks tired, we tell you before it becomes a problem under a brand-new roof.
Beloit Storm History From NOAA Records
Old roofs and strong storms are a hard mix. NOAA’s Storm Events Database, which collects National Weather Service reports and damage surveys, lists these Beloit events:
- April 19, 2011: a thunderstorm gust estimated at 75 mph, with heavy rain and hail, collapsed the roof of a day care center in the city.
- March 31, 2023: an EF0 tornado began in the Merrill Park area in the center of Beloit and uprooted trees across the east side.
- April 17, 2026: hail up to 2 inches across was reported on the east side of the city.
If your roof was in one of those storms, read hail damage roof repair in Beloit to see what we look for, then schedule a free inspection or call (815) 624-6278.

Rental Homes and Two-Flats
Beloit has a large rental market. Census estimates show about 59% of occupied homes are owner occupied, compared with roughly two thirds in Janesville. If you own a rental, we can plan the day with you and your tenants and send you photos of any replaced boards and the finished roof, so you can see the job without driving over.
Shingles That Suit an Older House
Architectural asphalt shingles are a good fit on Beloit’s older homes. Their thicker, layered look suits a steep roof and helps hide the small dips an old frame tends to have. We also install metal roofing for homeowners who want it. On a qualifying GAF shingle roof, we can offer a 50-year GAF warranty with up to 30 years on workmanship (GAF eligibility rules apply).

How Much Does a Roof Replacement Cost in Beloit, WI?
Most full asphalt roof replacements in Beloit run about $8,000 to $16,500+, depending on the house and how many times it has been reroofed. With the median Beloit home built in 1957, old layers and plank decking are often what push a job toward the higher end.
What Your Free Beloit Estimate Includes
- A free inspection with photos of the roof and the chimney flashing.
- The per sheet decking price, written into your estimate before we start.
- Martin Exteriors pulls and handles all required permits.
What shapes a Beloit roof price:
- Plank decking. Gapped or soft planks may need boards replaced or new sheathing at a per sheet price.
- Layers. A roof that went over the one before it means a heavier tear off.
- Venting, chimney flashing and extras. Rooms under the roof often need venting added, and chimneys get new flashing.
- Roof size. Two stories and two flats cover more area than a small postwar house.
- Pitch. Steep older roofs take more staging.
- Shingle line. Architectural GAF shingles, premium lines and metal each price differently.

How a Beloit Roof Replacement Goes
Start to Finish
- Free inspection. We check the decking, the flashing at walls, dormers and chimneys, the ventilation and how many old layers are on the roof, and we show you what we found.
- A written estimate with no surprises. It names the GAF shingle line and every part of the system, and it lists the per sheet price for any rotted decking up front.
- Permit and a date. We pull the City of Beloit permit and set your install date, weather permitting.
- Full tear off, then the full GAF system. Every old layer comes off down to the deck, and soft boards are replaced. Then ice and water shield goes on every eave and valley, followed by underlayment, new drip edge and flashing, the ventilation your roof needs, and GAF shingles installed to GAF’s specs. As a GAF Master Elite contractor, we can offer GAF’s 50-year warranty on qualifying roofs. Most roofs are done in a day.
- Cleanup and photos. Debris gets hauled away, the yard gets a magnet sweep for nails, and you get photos of any replaced boards and the finished roof, which helps if the house is a rental you don’t live in.

Beloit Roof Replacement FAQ
How much does a roof replacement cost in Beloit?
Most full asphalt roof replacements in Beloit run about $8,000 to $16,500+. Older homes with extra layers, plank decking or venting needs tend to cost more, and so do premium shingles. The inspection is free, and decking prices are in your written estimate before work starts.
Do you replace roofs on Beloit rental houses?
Yes. We can plan the day with you and your tenants, and we send photos of any replaced boards and the finished roof so you can see the work even if you live out of town.
Why might my older Beloit roof need new sheathing?
Many older homes have plank decking with gaps, old nail holes or soft boards. If the planks cannot give new shingles a solid, even base, new sheathing over them may be the fix. You see photos and the price before that work is done.
Can a new roof help a hot upstairs bedroom?
It can help. On houses with rooms under the roof, adding intake and exhaust venting during the replacement lets heat escape from under the shingles. Insulation matters too, and we will tell you if yours looks thin.
Will my yard be protected during tear-off?
Yes. We cover landscaping and nearby areas with tarps, haul away all the debris and run a magnet over the yard for nails before we leave.
Can an older Beloit house get a 50-year GAF warranty?
Often, yes. That warranty depends on the new roof system qualifying under GAF’s rules, not on the age of the house. We check what your roof needs and confirm the options at the estimate.
Do I need a permit to replace my roof in Beloit?
Most reroofing jobs in Beloit need a building permit, and the City of Beloit Planning and Building Services Division handles them. The city says a permit is required before alteration or repair work, except for minor repairs or maintenance valued at $1,000 or less that do not change the structure. Martin Exteriors pulls and handles all required permits, so you have nothing to file yourself. See the City of Beloit Planning and Building Services page.
How long does a roof replacement take in Beloit?
Most roofs are done in a day. Large two-stories, two-flats and roofs with several old layers to strip can take longer, and you will know the plan before we start.
Will insurance pay for a new Beloit roof after hail?
That depends on your policy and what your insurer finds. NOAA’s Storm Events Database lists hail 1.75 and 2 inches across in Beloit on the afternoon of April 17, 2026, so if your roof was in that storm’s path, a free inspection is a good first step. We document the damage with photos and measurements, meet your adjuster at the house, review the estimate with you line by line, and prepare and submit supplements when damage was missed, with you approving each step. You file the claim and pay your deductible, and your insurance company decides what is covered.
Do you offer financing for a Beloit roof replacement?
Yes. Financing is available with payments as low as $149/month for qualified buyers. See our financing options.
Is Martin Exteriors a licensed roofing contractor in Wisconsin?
Yes. We hold Wisconsin license 1436189 and Illinois roofing license 104.017824, and we are bonded and insured. Our Roscoe office at 11704 Main St is 10 to 15 minutes from Beloit, and we will show proof of insurance on request.
Has Beloit had a tornado or damaging winds recently?
Yes. NOAA records an EF0 tornado on March 31, 2023 that started in the Merrill Park area and crossed the east side of the city, and a few days later, on April 5, 2023, straight line winds up to 80 mph crossed Beloit from the west side to the east side. A free inspection shows whether storms like these loosened or creased your shingles.
