Roof Replacement FAQs
How long does a roof replacement take in Southern Wisconsin?
Most residential replacements in Janesville and Southern Wisconsin take one to three days depending on roof size, pitch, and weather; flat-roof commercial replacements run on their own schedule. We give you a clear timeline before we start.
Do I need a permit for a roof replacement?
In most Southern Wisconsin municipalities a full roof replacement requires a building permit and a final inspection, and Wisconsin limits overlay re-roofing to two layers before a tear-off is required. We pull the permit and schedule the inspection so you don't handle the paperwork.
Can you replace just one section of my roof?
Yes—if only one slope or section is failing we can replace that plane and blend it with the existing roof. If the whole roof is the same age and material, we'll tell you honestly whether a partial or full replacement makes more sense.
Do you repair the roof deck during a replacement?
We always tear off to the deck and inspect it. Any soft, rotten, or water-damaged plywood is replaced as part of the job so your new roof sits on solid decking—never over hidden rot.
