Why Is Your Hudson Roof Leaking?
A Hudson roof leaks where something has broken its seal: flashing that has pulled away at a chimney, wall or vent pipe, shingles torn off by wind or cracked by hail, or an ice dam that backs meltwater under the shingles in winter. Shingles shed water well across the open roof, so leaks almost always start at an edge, a joint or a damaged spot.
The stain on your ceiling is often not under the leak. Water that gets past the shingles runs along the roof deck and down the rafters until it finds a low point to drip from, which is why we follow it back through the attic before we touch the roof.
When we find the source, the same crew fixes it, whether that is a cracked vent boot, loose flashing or rotted decking. Leak repair is one part of our roof repair work.
Leaks on thaw days
Check for ice dams
A leak that appears on a mild winter day, with no rain, often comes from an ice dam at the eaves.
Where Hudson Roof Leaks Start
Hudson roof leaks start at the places where the roof is cut, joined or exposed: chimneys, walls, vent pipes, valleys, skylights and the eaves. Knowing which one sits above your stain usually narrows the search to one spot.
Around the Chimney
Flashing at the brick can rust, crack or pull loose, and chimney flashing repair replaces it so water stops running down the chimney.
Where the Roof Meets a Wall
Step flashing along dormers and second-story walls lets water in when pieces slip or were never woven in with the shingles.
At Vent Pipes
The rubber boot around a plumbing vent cracks with sun and cold, and water runs down the pipe into the house.
In the Valleys
Valleys carry water from two slopes at once, so a worn or badly lapped valley shows up as a leak fast.
At Skylights
The flashing kit around a skylight can fail, or the seal in the skylight itself can give out.
At the Eaves in Winter
Ice dams hold meltwater at the roof edge until it backs up under the shingles, and ice dam removal clears it.

How We Find and Fix a Roof Leak
We find a roof leak by starting at the stain inside, following the water back through the attic, and then checking the roof above that spot for the break. Once we know the cause, we repair it and check the wood around it before we close it up.
- 1
Look at the Stain
We note where the water shows inside and when it leaks: in heavy rain, on thaw days, or only with wind from one direction.
- 2
Follow It Through the Attic
In the attic we look for wet decking, stained rafters and damp insulation to find where the water first comes through.
- 3
Inspect the Roof Above
On the roof we check the flashing, shingles, vent boots and valleys over that spot and show you what we find.
- 4
Repair the Cause
We replace the failed flashing, boot or shingles, weaving new pieces in with the old so water sheds the way it should.
- 5
Check the Deck and Clean Up
Soft or rotted decking under the leak gets replaced before the shingles go back, and we leave the job site clean.

Should You Repair the Leak or Replace Your Hudson Roof?
Repair the leak when it comes from one spot on a roof that is otherwise sound, and replace the Hudson roof when leaks keep appearing in different places or the shingles are worn out across the roof. A single failed vent boot on a ten-year-old roof is a repair; a third leak in two years on a worn roof is a sign the roof is done.
Fix the leak when
- The water comes in at one chimney, wall, vent or valley
- The shingles around it still lie flat and hold their granules
- The deck under the leak is dry or only a small patch is soft
- This is the first leak the roof has had
Plan a new roof when
- Leaks keep starting in new places
- Shingles are curling, cracked or bare across the roof
- The attic shows water stains in several spots
- The deck is soft in more than one area
If the roof does need replacing, we tell you plainly and explain why, with no pressure to decide on the spot.

What Does Roof Leak Repair Cost in Hudson?
Roof leak repair costs $350 to $1,500 on a national range, not a quote, since no cost guide publishes a figure for Hudson. Where your repair falls depends on the cause: new flashing or a vent boot sits at the low end, while rotted decking under a long-running leak pushes it up.
Fixing a leak early costs far less than fixing what it ruins. A Wisconsin range for water-damage repairs inside the house runs $2,000 to $10,000 or more, and if water is pouring in right now, call us for emergency roof repair any hour of the day.

Wisconsin Rules That Apply to a Roof Leak Repair
A roof leak repair in Wisconsin has to restore the flashing the state dwelling code requires at chimney-roof joints, in all valleys and around all roof openings, and in the city of Hudson it needs no building permit unless the repair is structural. Most leak repairs replace flashing or shingles only, so in the city they go ahead without a permit; in the villages and towns around Hudson, we confirm the permit rules with your local building inspector before work starts.
Leaks at the eaves fall under the state's ice-dam rule. Shingle or shake roofs over heated space with a slope of 4:12 or less must have ice-dam protection, either sheet metal or an ice-and-water membrane, running at least 30 inches up the slope from the roof edge and at least 12 inches past the inside face of the outside wall. When we repair a leaking eave, we check that protection is there.
Leaks around a wall or vent usually come down to flashing, and our roof flashing repair work replaces it to those rules.
Roof Leak Repair FAQs
Can a Roof Leak Be Fixed in Winter?
Yes, a roof leak can be fixed in winter, though cold changes how the work is done. Shingle makers treat 40°F and below as cold-weather installation, when the sealant strips will not bond until it warms up, so we hand-seal new shingles as the manufacturer directs.
Why Does My Roof Only Leak in Winter?
A roof that leaks only in winter usually has an ice dam. Heat from the house melts snow on the upper roof, the water refreezes at the colder eaves, and the meltwater behind that ice backs up under the shingles.
Will Homeowners Insurance Pay for a Roof Leak?
Homeowners insurance pays for a roof leak when it comes from a covered loss, such as wind or hail damage, minus your deductible. A leak from a roof that has simply worn out is the owner's cost to fix.
Is the Leak Always Right Above the Stain?
No, the leak is often not right above the stain. Water runs along the roof deck and rafters before it drips, so we trace it through the attic to find where it actually comes in.
What Should I Do Until the Leak Is Fixed?
Until the leak is fixed, catch the water in a bucket, move belongings out of the way, and photograph the damage before you clean anything up. Stay off the roof, especially when it is wet or icy.
