Most full asphalt roof replacements in Janesville run about $8,500 to $18,500+, and in Beloit about $8,000 to $16,500+. In Milton, most run about $7,000 to $16,000+, and in Clinton about $6,500 to $16,000+. Where your roof lands depends on its size and pitch, how many layers come off, the condition of the decking underneath and the shingle you pick. Most jobs are done in about a day, and the only number that counts is the one we put in writing after a free inspection and estimate.

Why One Rock County Roof Costs More Than the House Next Door
Two houses on the same street can get very different numbers. Here’s what moves it:
- Size and pitch. Your roof has more surface than your floor plan, because it slopes and hangs past the walls. A steep roof also takes more time and more safety setup.
- Layers coming off. A roof that was covered over once already has two layers to strip and haul away. More layers mean more labor and more disposal.
- The decking underneath. Nobody can see the boards until the old shingles are off. Soft or rotted decking gets replaced so your new roof has a solid base, and your estimate spells out how that’s priced.
- Ice and water shield. Every Martin roof gets ice and water shield along the eaves and in the valleys, where winter melt backs up.
- Attic airflow. If the attic can’t breathe, shingles age faster. We check how air moves through it and tell you if it needs work.
- The shingle you choose. Most homes here get architectural shingles. Designer lines cost more.
Hail and Wind: When Insurance May Pay
If a storm damaged your roof, your homeowner’s insurance may cover the replacement minus your deductible. You file the claim and stay in charge of it. We inspect the roof, document the damage and can meet your adjuster. For a real example, see this hail roof replacement in Beloit.
Repair or Replace?
Not every leak means a new roof. At Martin Exteriors, the most basic repairs have a $750 minimum, and most repairs run about $750 to $1,900 (see our roof repair pricing). If your roof is near the end of its life, or the damage is spread across it, that money usually does more as part of a replacement. We’ll tell you straight which one your roof needs.
Permits in Rock County Towns
Permit rules change from city to city. Janesville, for example, asks for a permit when the roof structure is being changed or the house is in the historic district, and Beloit requires one for most reroofs. Our Wisconsin permit guide lists each city’s rules with links to the sources. When your job needs a permit, we pull it.
