Chimney flashing is the metal barrier installed at the intersection of your chimney and your roof that prevents water from entering at that critical junction. When flashing fails — and it does fail, typically within 15 to 20 years depending on material and installation quality — water enters directly into your roof assembly and wall framing behind the chimney. By the time you see a stain on a ceiling near the fireplace, water has already been traveling through your home's structure for some time. DME Maintenance diagnoses and repairs chimney flashing throughout South Farmingdale, NY and all of Nassau County, NY.
Most chimney-area roof leaks in South Farmingdale are flashing failures, not shingle failures. The chimney punches through the roof and creates an intersection that must be sealed against wind-driven rain, melting snow, and ice. That seal is maintained by two layers of flashing: step flashing that interleaves with the shingles along the chimney's sides, and counter flashing that is embedded into the chimney mortar joints and laps over the step flashing. When either layer corrodes, separates, or was installed incorrectly to begin with, the leak begins. We identify every flashing failure point before recommending any repair.
Our flashing repair work in South Farmingdale uses lead-coated copper or galvanized steel depending on the existing system. We re-embed counter flashing into fresh mortar reglets, reseal step flashing counter-laps, and address any related crown or masonry issues found during our assessment. Chimney flashing repair in South Farmingdale is priced by scope after a free on-site evaluation. Call 516-690-7471 today.

★★★★★"He pulled back some of the shingles, replaced all the flashing around the chimney base, and re-sealed everything. Explained what he was doing as he went. Took longer than I expected but he didn't cut corners. No more drips in the attic." – Wei Zhang (April 2026)
★★★★★"Our chimney flashing was shot and we were getting water in the house every time it rained. I called Doug and he came out to fix it. Put in new flashing, made sure it was all tucked in right. Hasn't leaked since. So relieved." – Nancy Gibson (May 2026)
