Roof Dryer Vent Cleaning in San Diego, CA

What a roof-vented dryer in a two-story San Diego home actually does

Upstairs laundry closets changed everything. Builders stacked them near bedrooms. The duct leaves the dryer, turns up, and climbs a stud bay. Lint does not climb well. It falls back to the first elbow and stays. The roof cap catches the rest. On tile roofs the cap sits low between barrel courses. Debris from Torrey pines and eucalyptus lands there. House finches nest in the flappers. We pull nesting material off coastal roofs often.

Older stock behaves differently. Craftsman bungalows in North Park and South Park vent through a crawlspace or a short sidewall. Those runs are mostly horizontal and reachable. Mid-century ranch homes in Clairemont and Allied Gardens are similar. Different failure, different visit.

Dry inland air hides the warning sign. You will not see condensation at the joints. The tell here is a laundry room that feels warm with the door shut.

Both ends get worked. Rods and a spinning brush handle the appliance side. Roof access clears the top of the run. A vacuum finishes the job at the dryer connection. Bottom-only cleaning just relocates lint into the cap.

Ask whether your cap has a screen. Screens belong on bath fans, not dryers. Removing one is often the whole fix.
