Roof Dryer Vent Cleaning in Bridgewater, NJ

Why does the roof cap clog before the rest of the run?

Because the last few feet are the coldest. Warm wet exhaust meets a cold metal jack. Moisture condenses right at the hood. Loose lint turns into a hard paste there. Winter makes it worse. The rest of the duct can look fine while the cap is nearly sealed.

Second-floor laundry closets in Bridgewater usually vent straight up a chase to a roof jack. Townhome and condo stacked closets share that chase with no accessible midpoint. That means two working ends only: behind the dryer and on the roof. We brush up from the appliance with rotating rods, then clear the cap from above so debris is not just pushed back into the run.

Roof caps also collect what the roof collects. We find leaf litter up there. Maple seeds too. Shingle grit as well. Birds nest in spring terminations. A screened dryer cap is a defect, not a feature. It packs with lint fast and should come off.

Old white vinyl or foil flex inside a chase is not a cleaning job. It is a replacement job. A steep pitch can change how we approach the top. So can wet shingles or slate. Sometimes the work stays inside the house entirely.
