Not every roof problem needs a full replacement. Here's how to know when a repair will do — and how to make sure it's done correctly.
Common roof repairs in Wisconsin cost $300–$1,500 for localized issues like missing shingles, minor leaks, or damaged flashing. Emergency tarping and leak repair is available 24/7. Roof repair is appropriate when damage is isolated and the overall roofing system is still in good condition (under 15 years old with no widespread issues).
In 15+ years of working across Waukesha and Milwaukee counties, these are the roof repairs we see most frequently:
Cost: $150-$400
Wisconsin's 60+ MPH wind events regularly tear off shingles, especially on older roofs or improperly nailed installations. This is usually a quick fix — we replace the missing shingles and check surrounding areas for hidden damage.
Cost: $200-$600
Flashing around chimneys, skylights, and wall junctions is the #1 source of roof leaks. Wisconsin's freeze-thaw cycles work the sealant loose over time. We re-flash with proper step and counter-flashing techniques.
Cost: $500-$2,000+
Ice dams can lift shingles, damage gutters, and force water into your home. Repair often includes shingle replacement, new ice and water shield at the eaves, and addressing the root cause (ventilation).
Cost: $200-$400 per boot
The rubber boots around plumbing vents crack after 10-15 years in Wisconsin's UV and temperature extremes. A cracked boot is a guaranteed leak path.
Cost: $400-$1,000
Valleys carry the most water volume. Damaged valley flashing or improperly woven valleys in Wisconsin's heavy rain and snowmelt lead to serious leaks. We install proper metal valley flashing with ice and water shield underneath.
Cost: $75-$150 per sheet
Water intrusion rots the plywood decking. We replace affected sections and investigate the leak source to prevent recurrence.
This is the most important decision, and it's where an honest contractor earns your trust.
Minor repairs (missing shingles, pipe boots) cost $150-$400. Moderate repairs (flashing, small leak sections) cost $400-$1,000. Major repairs (ice dam damage, valley work, multiple areas) cost $1,000-$2,500. DT Exteriors provides free inspections and honest assessments of whether repair or replacement is the right call.
We strongly advise against DIY roof repairs for safety reasons. Wisconsin roofs are especially dangerous — steep pitches, ice, and wet conditions create fall risks. More importantly, improper repairs often cause more damage than they fix. A failed DIY patch can void your insurance coverage for future claims.
If the damage was caused by a covered event (storm, hail, wind, fallen tree), insurance typically covers the repair minus your deductible. However, insurance does not cover repairs due to normal wear and tear or deferred maintenance. DT Exteriors helps document damage for insurance claims at no charge.
