Kenosha crosses freezing between night and day on about 81 days a year, and each of those cycles melts a little roof snow and refreezes it lower down.
Freeze-thaw at the flashing in Kenosha
一年 81 天日夜跨越冰點但積雪只有 0 cm——損傷集中在煙囪與天溝的收邊，不是冰壩; 屋齡中位 1970 年——多數屋頂已經換過至少一次，接縫與收邊的做法是上一代的.
That matters because it changes where the repair goes. Damage driven by ice at the eave is fixed at the eave with membrane and ventilation work; damage in the middle of the slope is a different job. A roofer who quotes the same fix for both has not been in your attic.
What roof work costs
| Repair | Installed price | Typical cause | How long it holds |
|---|---|---|---|
| Shingle patch | $350-900 | Wind lift or impact | Life of the surrounding roof |
| Step or chimney flashing | $400-1,400 | Sealant failure at a joint | 15-25 years done properly |
| Ice and water membrane at eave | $600-1,800 | Repeated ice damming | Life of the roof |
| Valley rebuild | $900-2,600 | Water concentration at the fold | 20+ years |
| Full replacement | $9,000-26,000 | Age across the whole slope | 20-30 years |
The median home in Kenosha dates from 1970, so most roofs here are on their second or third covering and the detailing underneath is of that era.
Kenosha also takes about 922 mm of rain a year, which is what finds any gap the winter has opened up.
National ranges, 2026
| Work | Typical installed cost | What decides it |
|---|---|---|

| Attic ventilation correction | $500-2,200 | Often the actual fix |
| Full replacement, asphalt | $9,000-26,000 | Square footage and layers to strip |
These are national ranges. We have not collected enough quotes in Kenosha to publish a defensible local range, and we would rather say so than invent one.

81 freeze-thaw cycles a year age the flashing before the shingles
Roofs in Kenosha go through freezing and thawing about 81 days a year. Shingles tolerate that reasonably well; **the joints do not.** Metal flashing expands and contracts at a different rate than the deck it is fastened to, and after enough cycles the sealant at chimneys, valleys and sidewalls opens up. That is why so many leaks here are found at a penetration on a roof whose field is still in good condition. When a quote says reuse existing flashing, ask how old it is and what condition the sealant is in.
Houses here average 1970 - budget for the deck, not just the shingles
The median Kenosha home dates to about 1970. Roofs of that vintage often have plank decking rather than plywood or OSB, and sometimes more than one layer of old roofing over it. Both change the price after the tear-off starts. **Ask for the per-sheet decking replacement rate in writing before work begins**, and ask what the quote assumes about the number of existing layers. This single line is the most common source of a bill that lands higher than the quote.
Who pulls the permit - and whose name is on it
Work in Kenosha is permitted through Kenosha County. Two questions decide whether a quote is honest: **does the price include pulling the permit, and will the company pull it in its own name?** A contractor who asks you to pull it as the homeowner is moving liability onto you - if the inspection fails, it is your permit that failed. Ask for the licence number the permit will be filed under, then check it against the state licence board before you sign anything.
Questions homeowners in Kenosha ask
The stain is in the middle of the ceiling. Is the hole above it?
Usually not. Water enters at a penetration or a seam, runs along the underside of the deck or a rafter until something stops it, and only then drips. A roofer who goes straight to the point above the stain without tracing it back uphill is guessing. Expect them to be in the attic with a light before they price anything.
Are icicles at the gutter a problem or just cold weather?
Icicles themselves are cosmetic. What they tell you is that snow on the roof is melting and refreezing at the eave, and that is the mechanism that pushes water back up under the shingles. The underlying cause is almost always heat escaping into the attic, which is why the durable fix is insulation and ventilation rather than knocking the ice off every winter.
Should I claim on insurance?
For storm and hail damage, usually yes, and it is worth getting an independent assessment before the adjuster arrives. For age-related failure or repeated ice damming, generally no - policies cover sudden events, not wear or maintenance, and a denied claim still sits on your record.
Is a repair worth it on a roof over 20 years old?
For a genuinely isolated problem like one section of flashing, yes. For anything spread across the slope, no. Asphalt is typically rated 20-30 years and the failure curve steepens sharply at the end, so money spent patching in the last few years is rarely recovered.
