Roof Dryer Vent Cleaning in Houston, TX

Why does the roof vent clog faster than a wall vent?

Because lint has to climb. A roof-terminated run on a two-story subdivision home goes up through the attic, turns two to four times, and exits through a roof jack. Every elbow sheds speed. Lint settles at the bends. Then Houston humidity gets into it. Damp lint packs instead of blowing free. Add the flapper hood and its screen, and you get a felt mat at the top.

Count elbows before you blame the dryer. Each one eats into the 35 ft equivalent-length allowance. Many attic runs pass that limit once you do the math. No amount of cleaning fixes an over-length run. It just buys months.

The work is done from both ends. Rotary brush on flexible rods, fed from the laundry connection. The roof jack comes off so the hood and screen clear by hand. Nests get pulled, not pushed. We check the attic section for condensation staining during winter fronts, since a sweating duct means lint is sticking.

Tell-tale signs: jeans needing a second cycle. A hot laundry closet. Mildew spotting on closet drywall from back-drafted moist air. Annual is the Houston baseline. Roof runs push that higher. So do pets or a full house move.
