If your chimney leaks when it rains, the flashing is almost always to blame — not the chimney itself. Roofers NJ repairs and replaces chimney flashing across New Jersey, sealing the most common leak point on any roof.
The joint where your chimney meets the roof is the single most common source of roof leaks, and the reason is almost always failed flashing. Flashing is the layered metal that seals that joint, and when it deteriorates, pulls loose, or was installed poorly to begin with, water finds its way in. Roofers NJ specializes in diagnosing and repairing chimney flashing across New Jersey, stopping the leak at its source.
A masonry chimney and a roof are two different materials that expand, contract, and settle at different rates. The flashing system bridges that gap and keeps water out. It's a layered system: step flashing woven into the shingle courses along the sides, base flashing at the front, and counter-flashing set into the mortar joints of the chimney itself. When any layer fails — corrodes, pulls away, or loses its seal — water runs straight down the chimney into your home. Homeowners often assume the chimney is "cracked," but the masonry is usually fine; it's the flashing that's failed.
Not every flashing problem needs a full replacement. Sometimes the seal at the counter-flashing has simply degraded and can be properly resealed; sometimes a section of step flashing has corroded and needs replacing. But flashing that was installed incorrectly — surface-mounted instead of woven in, or sealed with nothing but a heavy bead of caulk — needs to be redone correctly to last. We'll assess what you have and recommend the repair that actually solves the problem rather than a quick patch that fails again next season.
New Jersey's freeze-thaw winters are especially hard on chimney flashing. Water that seeps into a marginal flashing seal expands as it freezes, widening the gap a little more with every cycle until a minor flaw becomes an active leak. Driving rain from nor'easters tests every seam. This is why a chimney flashing repair done correctly — with proper step and counter-flashing, not just caulk — is so important here. A correct repair lasts for decades; a caulk-only patch lasts a season or two.
