Flashing, Chimney & Skylight Repair in Buffalo, NY · Metal Roofing Alliance Member

Buffalo roofs take a beating that most of the country never sees. Lake-effect snow piles up against chimneys and skylights, ice dams form at the eaves, and the freeze-thaw cycle between the Niagara Escarpment and Lake Erie works every seam loose. When water finds a gap around a chimney, a skylight curb, or a dormer, it shows up as a brown ring on the ceiling in Allentown, a wet spot in a Parkside attic, or a drip down a brick wall in a Buffalo double. That is why Flashing, Chimney & Skylight Repair in Buffalo is the call we get most after a hard winter. We bend, fit, and seal flashing in-house so the metal actually follows the contour of your roof instead of being forced into a gap. If the leak has already spread, start with our metal roof leak repair page and we will trace it to the source.

Why Flashing Fails First on Buffalo Roofs

Flashing is the thin metal that bridges the roof surface and anything poking through it: chimney, skylight, vent, dormer wall, valley. It is the most stressed material on the roof because it has to move with the house while staying watertight. In Buffalo, that stress is extreme. Snowvember 2014 and the December 2022 blizzard dumped feet of snow in hours, and the melt that followed pushed water sideways under every loose edge. Older homes in Black Rock, Kaisertown, and South Buffalo often still have original galvanized flashing that has rusted through, while 1990s homes in Amherst and Clarence have sealant that has dried and cracked.

• Ice dams push meltwater backward under flashing and into the attic, so the leak shows up far from the actual gap.
• Chimney flashing on masonry fails when the counter-flashing is not cut into the mortar joint, letting water run behind the metal.
• Skylight curbs on 1970s and 1980s homes in Tonawanda and Kenmore often have cracked plastic seals that no amount of caulk will fix.
• Step flashing along dormers and sidewalls loosens as the roof deck moves through freeze-thaw cycles.
• Valley flashing on complex Victorian roofs in Elmwood Village and the Delaware District collects debris and holds moisture against the metal.

Every one of these failures is fixable, and fixing them early is far cheaper than replacing rotted sheathing and insulation.

Key info: A homeowner in West Seneca called us after noticing a stain on the ceiling below a skylight. The curb flashing had separated by a quarter inch, and the next melt would have soaked the drywall. We re-flashed the curb and replaced the seal in one visit.

For official guidance on roof permits and inspection requirements, check the City of Buffalo building department before scheduling major work, since rules vary by jurisdiction.

How We Repair Flashing, Chimneys, and Skylights in Buffalo

We do not guess at leaks. We get on the roof, find the actual entry point, and fix the metal, not just the stain. Our process is built around Buffalo conditions: heavy snow load, ice damming, and wind off Lake Erie that drives rain sideways. We fabricate flashing on site from coil stock so it fits your chimney or curb exactly, with no gaps that a tube of caulk is supposed to hide. If the roof has other issues, we note them, but we stay focused on the flashing scope you hired us for.

1. We inspect the roof, attic, and interior ceiling to trace the water path and confirm the source.
2. We remove the failed flashing and any damaged sealant, then clean and dry the substrate.
3. We cut and bend new flashing to match the chimney, skylight curb, or wall profile.
4. We install the flashing with proper overlaps, fasteners, and sealant rated for Buffalo winters.
5. We test with water where possible and check the interior after the next rain or melt.

For homes in the 14203 ZIP code and around downtown Buffalo, we also handle historic profiles where the flashing has to match the original detail. See our Buffalo 14203 service page for neighborhood specifics.

Key info: On a 1920s brick double in Parkside, the chimney flashing had been patched with roofing cement three times. We cut a new reglet into the mortar joint, installed new counter-flashing, and sealed it properly. That ended a leak that had stained the ceiling for two winters.

Flashing Repair Methods We Use

Not every flashing problem calls for the same fix. The right approach depends on the roof material, the age of the home, and how much damage the leak has already done. Here is how we match the method to the job.

If you are also seeing loose fasteners or backed-out screws, our screw replacement and re-fastening service handles that part of the repair.

Flashing, Chimney & Skylight Repair Cost in Buffalo: What to Expect

Most flashing repairs in Buffalo start around $600 and go up from there. That starting point covers a straightforward fix, such as resealing a single skylight curb or replacing a short run of step flashing. The price climbs when the job involves a full chimney re-flash, rotted sheathing, or a roof that needs to be opened up to reach the leak. Homes with steep pitches, multiple chimneys, or slate and tile roofs take more labor and time.

Access matters too. A chimney on a two-story home in North Buffalo is a different job than a ranch in Cheektowaga. So does the material: copper flashing costs more than galvanized, but it lasts decades longer and is the right call for historic homes in the Delaware District. Getting two or three estimates is smart, and it helps you compare scope, not just price. Ask each contractor what they will replace and what they will reuse.

Choosing a Metal Roofing Contractor Near Buffalo for Flashing Work

Flashing repair is not the place to hire the cheapest bid. A bad flashing job will leak again with the first big snow, and by then the damage has spread. Here is what to check before you sign anything.

• Confirm the contractor is licensed and insured, and ask for a certificate of insurance before work starts.
• Get at least two or three written estimates that describe the scope in detail, not just a lump sum.
• Ask for local references, especially from homes with similar roofs and chimneys in Buffalo or nearby towns.
• Check whether a permit is required for your scope, since rules vary by jurisdiction and historic districts may have design review.
• Ask how the contractor will protect your roof and landscaping, and who handles cleanup and disposal.
