Roof Jack / Vent Cap Replacement in League City, 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 League City (4 ZIP codes, 114k residents) and surrounding neighborhoods with same-week scheduling.
