How Much Does Roof Replacement Cost in Janesville?
Asphalt-shingle replacement in Janesville, Wisconsin runs $6,580 to $14,570 (2,000 sq ft, tear-off and underlayment included). That is the national base range scaled by Janesville's labor-and-materials index of 0.94× — 6% below what the same job costs nationally, in a county NOAA credits with 39 hail events over the last 10 years.
Janesville's 2020 census population was 65,615. After the General Motors Assembly Plant -- the oldest GM plant in North America prior to closing -- shut down in December 2008, the economy shifted toward healthcare and public sector anchors including Mercy Health System and the Janesville School District. The closure left a large industrial building stock requiring ongoing maintenance and re-roofing, while the surrounding residential neighborhoods hold aging housing that drives demand for residential contractors.

Janesville vs the Wisconsin Average

Cost indexes barely move across this corridor, so the ranges above track each other — what separates these markets is supply and storm exposure. Kenosha, the closest at about 61 miles, lists 29 contractors against Janesville's 22, and its county logged 11 hail events to Janesville's 39 over the same decade. A quote that ignores those local factors deserves a follow-up question.

NOAA Storm Events data shows 39 hail events in Janesville's county over the last 10 years, with hail up to 2.00″ (most recent on record: 2024-06-25). Stones that size punch through shingles rather than bruise them. At 39 events in a decade, Janesville roofs live on an insurance cycle: quotes here should price impact-resistant Class 4 shingles (10–20% more upfront, often offset by an insurer premium discount) and you should know your wind/hail deductible before the next storm, not after.
