Bath Fan and Roof Vent

7 photos · bathroom

The original bathroom had no exhaust — moisture was rotting the ceiling. I cut into the bath ceiling, ran flex duct through the attic joists under the vapor barrier, set a new fan/light combo, and put a black roof cap on the asphalt to vent it cleanly outside. No more soft drywall above the shower.

  1. Roof before — frost on the old shingles. The valley is where the new vent cap had to land. Before
