Most residential roof replacements in south-central Wisconsin - think a standard ranch or two-story in Madison, Janesville, or Monroe - are done in one to two days. Larger or steeper roofs, multiple tear-off layers, or bad decking underneath can push that to three or four days. Rarely does a straightforward job go longer than a week.

Your roof is leaking, or your insurance adjuster just told you it needs to be replaced, or you've been watching those shingles curl for two winters now and you finally decided to do something about it. The first thing most homeowners want to know isn't even about cost - it's how disruptive is this going to be?
Fair question. Let's walk through it honestly.
The Short Answer: One to Two Days for Most Homes
A typical single-family home in south-central Wisconsin - a ranch in Fitchburg, a two-story colonial in Janesville, a Cape Cod in Monroe - gets a full roof replacement done in one full workday, sometimes two.
That's tear-off, inspection of the decking, ice-and-water shield, underlayment, new shingles, ridge cap, and cleanup. All of it.
Crews work fast not because they're cutting corners, but because roofing is physical, weather-dependent work and experienced teams have a rhythm. A five- or six-person crew can tear off and reshingle 30-40 squares in a day when conditions cooperate.
Roof replacement cost by home size (Madison, 2026)
| Home | Roof size | Typical total |
|---|---|---|
| Small ranch / bungalow | 14-18 squares | $9,000-$13,000 |
| Average two-story | 18-26 squares | $12,000-$18,000 |
| Large or complex (steep) | 26+ squares | $17,000-$25,000+ |
Cost by roofing material (average Madison home, installed)
| Material | Lifespan | Typical total |
|---|---|---|
| Architectural asphalt (standard) | 25-30 yrs | $12,000-$18,000 |
| Impact-resistant (Class 4) | 30+ yrs | $15,000-$22,000 |
| Standing-seam metal | 40-50 yrs | $25,000-$45,000 |
Common add-on costs
| Item | Typical cost |
|---|---|
| Extra tear-off layer | $500-$1,500 |
| Decking replacement | $50-$80 per sheet |
| New flashing & pipe boots | $300-$700 |
| Seamless gutters | $1,000-$2,500 |
Typical Madison-area 2026 ranges. Your exact price depends on an on-site inspection. A new asphalt shingle roof recoups about 61% of its cost at resale on average (2024 Remodeling Cost vs. Value Report).

What Actually Determines How Long It Takes
Size of the Roof
This one's obvious but worth saying plainly. A 1,200 sq ft ranch takes less time than a 2,800 sq ft two-story with a finished bonus room above the garage. Roofing is measured in "squares" - one square equals 100 square feet of roof surface. Most Wisconsin homes fall between 20 and 45 squares.
Pitch (Steepness)
A low-slope roof moves fast. A steep 10/12 or 12/12 pitch - common on older Victorian-style homes in Madison's near-east side or some of the farmhouses out in Green County - slows everything down. Crews need roof jacks, additional safety equipment, and more careful footing. Labor costs go up, and so does the timeline.
Number of Tear-Off Layers
Wisconsin building code generally allows up to two layers of shingles on a residential roof. If your house already has two layers, everything has to come off before new shingles go down. Two-layer tear-offs add time and disposal cost. Some older homes in Rock County we've worked on had layers going back 40+ years - that's a lot of weight and a lot of nails.
Decking Condition
This is the one that surprises homeowners most. Once the shingles come off, we can see the actual wood decking underneath. If there's rot, soft spots, or damage from years of ice dams (very common in Wisconsin), those boards need to be replaced before anything else goes on. We can't know exactly how much until we're up there. A good contractor will explain this upfront and price it per sheet of plywood rather than hiding it in a vague estimate.
Complexity of the Roof
Valleys, dormers, skylights, chimneys, pipe boots, multiple ridgelines - every penetration and transition point adds time. A simple gable roof is the fastest job there is. A roof with four dormers, two chimneys, and a skylight is a different project entirely.
Weather
This is Wisconsin. A clear forecast can turn into a pop-up thunderstorm by 2pm in July. Responsible crews won't leave your decking exposed to rain. Sometimes that means stopping mid-job and tarping everything until the next morning. It's not ideal, but it's the right call.
What About Cost? Real Ranges for 2026 in South-Central Wisconsin
We're not going to throw out a single number and pretend it's what you'll pay. That's not honest, and it's not useful.
Here's what actually moves the cost of a residential roof replacement in Dane, Rock, and Green counties right now:
Material choice:
- 3-tab shingles are the cheapest option but rarely recommended anymore - they're thinner and less wind-resistant.
- Architectural (dimensional) shingles are the standard for most Wisconsin homes. Better wind ratings, longer warranties, better look.
- Impact-resistant shingles cost more upfront but can lower your insurance premium and hold up better after a hail event - worth asking your agent about before you choose.
Roof size: The more squares, the more material and labor. Simple math, but the jump from 25 to 40 squares is significant.
Pitch premium: Steep roofs cost more per square to install. Expect a meaningful upcharge on anything over a 7/12 pitch.
Tear-off layers: One layer of tear-off is usually included in a base price. Two layers adds labor and dumpster weight.
Decking repairs: Priced per sheet, typically. Get a contractor who's upfront about this possibility rather than one who low-balls the estimate and hits you with surprise charges.
Permits and disposal: These are real costs. Make sure they're in the quote.
For a ballpark: most homeowners in this region are looking at somewhere in the $8,000-$20,000+ range for a full replacement with architectural shingles. A modest ranch with one layer of tear-off and clean decking sits toward the lower end. A large, steep, complex roof with two tear-off layers and decking issues can push well past that.
The only way to know what your roof costs is a real, in-person inspection and a line-item written estimate.
If you're trying to figure out your budget before you call anyone, that's completely reasonable - reach out to us here and we'll schedule a free, no-pressure inspection. No obligation, no hard sell.
What Happens the Day of Replacement
Knowing what to expect makes the day less stressful.
- Morning (early): Crew arrives, sets up tarps to protect landscaping, dumpster or trailer in the driveway.
- Tear-off: Old shingles come off first. It's loud. The whole house will vibrate a little.
- Decking inspection: We walk the deck, mark any soft or damaged spots, make repairs.
- Underlayment and ice-and-water shield: Wisconsin code requires ice-and-water shield at the eaves (at minimum) because of freeze-thaw cycles and ice dams. A good crew installs it properly - not just the code minimum.
- Shingles: Installed course by course from the bottom up.
- Ridge cap and flashing: Chimney, pipe boots, and valleys get properly flashed. This is where shortcuts show up on bad jobs - improperly sealed flashing is the #1 source of leaks on "new" roofs.
- Cleanup: Magnetic roller for nails, full debris removal, final walk-around.
Most of the time, you've got a finished roof by late afternoon.

A Note on Storm Damage and Insurance Jobs
If a hail or wind event prompted this replacement, the process has an extra layer. Insurance claims, adjuster visits, and supplement negotiations add time to the start of the project - not the installation itself.
We've been handling storm damage claims in south-central Wisconsin for decades. We meet your adjuster on-site to make sure nothing gets missed on the scope of damage. Adjusters move fast and don't always catch everything - a second set of experienced eyes matters.

Whether you call us or someone else, make sure you get answers to these:
- Is the estimate line-itemized (materials, labor, tear-off, permits, disposal separately)?
- How do you handle decking damage found during tear-off?
- Are you pulling the permit?
- Who's actually doing the work - your own crew or a subcontractor?
- What's the workmanship warranty, and who backs it?
A contractor who gets annoyed by these questions is telling you something.
- A price dramatically lower than every other bid (corners are getting cut somewhere)
- Pressure to sign on the spot, or a "today only" discount
- A request to sign over your insurance claim (Assignment of Benefits)
- An offer to "waive your deductible" (that is insurance fraud, and it puts you at risk)
- No written, itemized estimate, or no proof of insurance
- A large upfront payment (more than 30%) before any work begins
