Rochester’s humid continental winters dump lake-effect snow on Monroe County roofs, then freeze-thaw cycles push meltwater under shingles on Park Avenue and East Avenue Victorians. Ice dams form when heat escaping a poorly insulated attic melts snow at the ridge while the eaves stay frozen; water backs up, finds every nail hole, and drips into the attic. Homes near Charlotte catch extra lake moisture, so even a small flashing gap can soak insulation for weeks. We trace the leak from the attic side first—wet sheathing, stained rafters, or that musty smell—then open the roof only where the water actually entered, not the whole plane.
On Brighton, Irondequoit, and Pittsford colonials the same pattern shows up around chimneys, valleys, and plumbing stacks. Many of these roofs were built before modern ice-and-water shield, so the felt underlayment has long since dried and cracked. A leak that looks like a ceiling stain downstairs often started as a pinhole at a step-flashing joint; by the time you see it, the attic deck is already supporting mold. We never just patch the drip; we confirm the source with a hose test or infrared after a thaw, then replace the failed flashing and add a membrane that actually sheds ice-dam water. Work is scheduled around the snow load so we are not walking a loaded roof.
If you wait until spring, the wet insulation has already compressed and the mold has a head start. We cut out only the saturated batting, dry the wood, and leave the roof watertight so the attic can be treated later. Our shop at 1925 S Clinton Ave keeps us close to the east-side neighborhoods; calls come in Monday–Friday 8am–6pm and Saturday 9am–2pm. No invented warranties—just the workmanship you can see from the attic hatch before we close the roof.
Technician insight
In Rochester the thing that catches most people out with roof leak repair is assuming the drip is right above the stain. On Park Avenue and East Avenue houses the water often travels ten feet along a rafter after an ice dam, so you open the wrong spot and miss the failed step flashing. Lake-effect snow plus poorly vented attics make the ice dam the real driver, not a random missing shingle.
Ice dam drip over a Charlotte bungalow attic
Homeowner noticed a new stain on the bedroom ceiling after a January thaw. We found the water had entered at the eaves where ice had backed up under the first three courses, then run along the bottom chord into the insulation. We cleared the remaining ice, installed membrane from the fascia inward, replaced the wet batting, and left the roof tight so the wood could dry. No more drip on the next melt.

✓Pipe Boot and Vent Stack Repair
Swap cracked rubber boots and reseal plumbing stacks that let freeze-thaw water drip onto attic insulation.
✓Skylight Curb and Flashing Repair
Reseal or rebuild skylight curbs that leak when ice dams force water under the flashing on older Brighton and Pittsford roofs.

Locate the true entry point from inside the attic using moisture meters and visual clues instead of guessing from the ceiling stain.

How it works
- 1
Attic Inspection First
We start in the attic to map wet insulation, stained sheathing, and the path the water actually took—especially after ice-dam events in Charlotte and Irondequoit.
- 2
Source Confirmation
A controlled hose test or post-thaw check pinpoints the failed flashing, valley, or boot so we do not open more roof than needed.
- 3
Targeted Roof Opening
Only the damaged course is removed; ice-and-water shield and new flashing go in, matching the existing shingle profile on older Monroe County stock.
- 4
Dry-Out And Close-Up
Saturated insulation is pulled, wood is left to dry, and the roof is sealed so mold treatment can follow without another leak.
Pricing
Most targeted leak repairs on Rochester homes fall in a few hundred to low thousands depending on access, ice-dam damage, and how much wet insulation must come out; we give an on-site range before any tear-off.
