When to schedule roof in Janesville
We use NOAA's 1991-2020 climate normals for Afton - Janesville Wwtp (5 miles from the city center). These are 30-year monthly averages, not forecasts.
March through November is the stretch where exterior installation runs into the fewest weather problems in Janesville (9 of 12 months). January, February and December have an average daytime high under 45°F.
In January, February and December the average high stays below 45°F. Sealants, adhesives and some materials, such as vinyl, are harder to install well in the cold, and short daylight cuts the working day.
Janesville gets about 37 inches of precipitation in a normal year, including roughly 37 inches of snow. The wettest months are June, July and August (5.0 inches in June). Inside the workable window, March and November are the driest, at 2.1 and 2.3 inches. The station averages about 13 days a year at 90°F or above.
Does the season change the price? Probably, but we do not have a sourced seasonal price curve, so the estimator shows a year-round figure and does not adjust by month. When you collect quotes, ask whether scheduling in a slower month gets a better rate.

Specs and site conditions that change a Janesville bid
Permit
Roof replacement permits run $100-$500 depending on the location.
Shingle type
3-tab asphalt is $3-$5 per sq ft installed; architectural is $4-$6 (HomeGuide). Metal, tile and slate are separate projects with much higher ranges.
Roof area, not floor area
Pitch and complexity mean roof surface is larger than the house's footprint. A 1,500 sq ft ranch can have 1,800-2,200 sq ft of roof.
What nearby projects cost in Janesville

Local wages behind the labor line
Wages are the part of this estimate that changes most from town to town. 2 trades carry the job here, and each is compared with its US median. The weighted result for Janesville is 1.15 times the national level.
For roofers (47-2181, weighted 85%) the local median is $30.44 an hour, which is 14% above the national $26.65. The middle half of them earn between $26.83 and $37.51 an hour. BLS counts 70 of them working in the area, 10.0 for every 10,000 jobs (US: 8.7), so the local bench is about average.
Construction laborers (47-2061), 15% of the weighting: a median of $26.77 an hour, 18% above the US median of $22.66. The middle half of them earn between $22.00 and $36.28 an hour. About 480 work in the metro. That is 68.7 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.
Quotes come from real crews, not medians. If the roofers on your job are paid at the 75th percentile ($37.51 an hour) instead of the median, the labor line grows by about $1,300. At the 25th percentile ($26.83) it shrinks by about $660. The total moves by 13.0% or 6.6%, so wages alone rarely explain a quote that is far outside our range.
For context on the local economy, BLS counts 69,870 jobs in the Janesville-Beloit area. That makes it the 260th largest of the 300 metros we cover, with 0.04% of US employment.
