A Waukesha County homeowner's guide to replacing your roof — from the first inspection to the final walkthrough.
You should replace your roof when it reaches 20-25 years old, shows signs of widespread granule loss, has multiple leaks, or sustained significant storm damage. In Wisconsin, the average residential roof replacement costs $8,000–$25,000 and takes 1-3 days to complete.
Not every roof issue requires a full replacement. Here's how to know when repair isn't enough:
Understanding the process removes the stress. Here's exactly what happens when DT Exteriors replaces your roof:
A certified project manager inspects your roof, attic, and exterior. You receive a written, line-item estimate within 24 hours — no vague "package pricing."
Choose your shingle style, color, and profile. We bring physical samples to your home so you can see them against your siding and trim. We recommend options based on your home style and budget.
If storm damage is involved, we prepare the full claim scope using Xactimate software. Our project manager meets your insurance adjuster on-site. 98% claim approval rate.
We monitor weather forecasts 10 days out. Your project gets scheduled during a clear window. Materials are delivered the day before.
Crew arrives at 7:00 AM. Old roof stripped, decking inspected and repaired, full roofing system installed. Magnetic nail sweep of entire property. Most homes completed in 1 day.
Final inspection with you present. We register your Owens Corning warranty (up to 50 years on materials + our Lifetime Workmanship Warranty). Your property is left cleaner than we found it.

DT Exteriors offers 0% APR financing with approved credit, with terms from 12 to 144 months. A $15,000 roof can be as low as $104/month over 144 months. No prepayment penalties.
Most residential roof replacements are completed in 1-3 days. A standard single-story home is typically done in a single day. Larger homes with complex rooflines, steep pitches, or multiple stories may take 2-3 days. Weather delays are planned for in our scheduling.
Repair if the damage is localized (a few missing shingles, one small leak) and the roof is under 15 years old. Replace if the roof is 20+ years old, has widespread damage, multiple leaks, or significant granule loss. A free inspection from DT Exteriors will give you a clear, honest answer.
Yes. Most homeowners stay home during the replacement. It is loud — especially during tear-off. If you have young children, pets sensitive to noise, or work from home, you may want to plan to be away for the first half of the day. We recommend moving vehicles away from the house to avoid any debris.
We monitor weather carefully and only start projects when we have a clear forecast window. If unexpected rain occurs mid-project, we have tarps ready to cover exposed areas within minutes. Your home will be protected. We never leave exposed decking overnight without tarping.
Free inspections. Transparent pricing. Lifetime warranty on every project.
