Roof Dryer Vent Cleaning in San Antonio — Homeowner's Guide
If your dryer exhausts straight up through the roof, here's what you should know about cleaning, timing, and what to look for.
How roof venting works
The duct runs vertically through a wall chase or the attic and exits through a roof cap. Gravity, vertical lint settle-back, and limited access all make these vents harder to maintain than side-wall vents.

Frequently Asked Questions
+Why does my dryer vent go through the roof?
Two-story builds, townhomes, and homes with interior laundry rooms often run the vent straight up because it's the shortest path to outside air.
+Do roof vents clog faster than side-wall vents?
Usually yes. Lint settles back down the vertical run, and roof caps trap debris. They also collect bird nests in San Antonio.
+Can I clean a roof dryer vent myself?
We don't recommend it. Ladder work plus vertical brushing is a real safety risk. Hire someone with the right tools and a safe ladder setup.
+How often should it be cleaned?
About once a year for active households. Sooner if you have pets or notice longer dry times.
+Does the cap need replacing too?
Sometimes. Sun-damaged or bird-broken caps should be replaced. We can swap it during the cleaning.
