If you’ve started researching the cost to replace a roof, you’ve probably noticed the numbers online are
all over the place — $8,000 on one site, $30,000 on another. That’s because roof replacement cost depends on more variables than most homeowners realize, and because national averages don’t reflect what’s actually happening in the Madison market right now. This guide breaks down what actually drives the price, what to realistically expect, and how to get a number you can actually plan around.
The Short Answer
For a typical single-family home in the Madison area, the cost of a new roof generally falls somewhere between $10,000 and $25,000, with most projects landing in the $13,000–$18,000 range for a standard asphalt shingle roof. Larger homes, steeper rooflines, premium materials, or extensive tear-off work push that number higher. If you’re asking how much is a new roof for your specific house, the only way to know your actual number is a real, on-roof inspection — but this range gives you a starting point for budgeting.
Why Roofing Costs Have Risen in 2026
If your gut says “this feels more expensive than it used to,” you’re not wrong. Roofing material costs have climbed sharply due to tariffs on steel, aluminum, and imported lumber products, along with continued manufacturer price increases from Malarkey, GAF, Owens Corning, and CertainTeed. Even asphalt shingle roofs use dozens of metal components — flashing, drip edge, fasteners, vents — so metal tariffs affect nearly every roof, not just metal ones. This is part of why getting a new roof estimate sooner rather than later matters if a replacement is on your horizon.
What Actually Drives Your Roof Cost
1. Roof size and complexity
Roofers price in “squares” (100 sq ft per square), which is why roof cost per square foot and roof replacement cost per square foot are some of the most-searched ways homeowners try to estimate a project. A simple, low-pitch ranch roof costs less per square than a steep, multi-gable roof with lots of valleys, dormers, and cut-ins — more complexity means more labor and more waste.
2. Material choice
- Asphalt shingles — the most common and most affordable option, with a wide range of colors and warranty tiers
- SBS modified asphalt shingles — a step up from standard asphalt, using a rubberized polymer blend for added flexibility and impact resistance; a popular choice for hail-prone areas and can qualify for insurance discounts in some cases
- Metal roofing — higher upfront cost, but longer lifespan and strong performance in Wisconsin winters
- Slate roofing — premium cost and premium lifespan, typically reserved for historic or high-end homes
- Cedar/shake — distinctive look, higher maintenance and cost
3. Tear-off and decking condition
If your existing roof needs a full tear-off (rather than a layover, which most codes and contractors don’t recommend anyway), that adds labor cost. If the decking underneath has rot or damage, replacing sections of decking adds material cost — this is often the biggest “surprise” separating a rough new roof cost estimate from the final bill, and most of the time a good roof inspection should flag decking risk before work starts, not after tear-off.
Roof pitch and accessibility
Steep roofs require more safety equipment and slower, more careful work. Depending on the steepness of your roof, there could be additional charges.
Ice dam and ventilation issues
If your home has a history of ice dams, part of a proper roof replacement often includes improving attic ventilation and insulation — not just swapping shingles. Also, the standard for roofs is installing 2 rows of ice and water shield on the eaves and additional ice and water shield on both sides of the valleys. Skipping this step is why some homeowners replace a roof and still get ice dams the next winter.
Roofing Cost Per Square — A More Useful Number
Rather than one big number, it often helps to think of roofing cost per square. As a rough range for the
Madison market:
- Asphalt shingles: roughly $600–$875 per square installed
- Metal roofing: roughly $1,000–$1,750+ per square installed
- Slate: significantly higher, often $2,000–$3,500+ per square
These ranges include material and labor but will shift based on the complexity factors above — which is exactly why two “1,800 sq ft roof” quotes for a roof replacement estimate can look so different, even when the average cost of roof replacement in your area sounds like it should be a fixed number.
How Insurance Fits Into Your Roof Replacement Cost
If your roof damage is storm- or hail-related, your homeowner’s insurance may cover some or all of a replacement — but only if the claim is documented and filed correctly. This is one of the most overlooked ways to reduce your out-of-pocket roofing cost, and it’s also one of the most commonly mishandled parts of the process. We walk homeowners through this directly: documenting damage, meeting the adjuster, and making sure the settlement reflects the actual scope of work needed — not just what’s easiest to approve.
Financing a Roof Replacement
Given where roof replacement financing has landed in 2026, a growing number of homeowners aren’t paying cash upfront for a full replacement. Not every roofing company offers this, so it’s worth asking directly whether roofing companies that finance are an option before you assume a project is out of reach. If cost has been the thing holding you back, roofing financing options can turn a $15,000 project into a manageable monthly payment — worth exploring before you assume replacement isn’t possible this year.
Getting an Accurate Roof Estimate
Every one of the numbers above is a range, because your actual roof replacement cost depends on your specific home. The only way to get a real number — not a guess — is a free, on-site inspection that accounts for your roof’s size, pitch, current condition, and material preferences.
The Exteriors Company provides free roof inspections and detailed, transparent roof replacement estimates for homeowners across the Madison area.
