Roof Jack / Vent Cap Replacement in San Antonio, TX
When the dryer exits through the roof, the termination is a roofing detail as much as a venting one. We remove the old jack, clear the lint packed under it, and set a dryer-rated cap with a damper that swings free — never a screened termination, because a screen on a dryer exhaust is a lint trap by design. The flashing is woven into the shingle course above it and sealed so the penetration stays dry through the next storm. What the roof asks of us drives the price: a walkable composition roof is the base, while steep pitch, tile or metal, and second-story height that means rigging fall protection all cost time. That number is quoted before we climb. Serving San Antonio (110 ZIP codes, 1470k residents) and surrounding neighborhoods with same-week scheduling.

Local dossier · San Antonio, TX
A large share of San Antonio's houses are the slab-on-grade ranch homes built between the 1950s and the 1970s across the near north and northwest sides, and they share a layout habit: the washer and dryer live in the garage. That is usually good news for the duct, since the run is short and reachable, but it creates its own failure mode. Garage vent hoods get painted over during resale prep, blocked by shelving or a second refrigerator pushed against the wall, and fitted with insect mesh that clogs within weeks. Most of the city is on electric service rather than gas, so combustion is rarely the concern here. Heat is. And with a large military population moving in and out of housing around the JBSA installations, plenty of these homes change hands often enough that no single owner ever concludes the vent is their responsibility. It is a big, spread-out city with a surprisingly consistent laundry room.
