Porch Floor Boards Moisture Problem
- While the gutter is catching most of the rain coming off the roof, it’s proud of the roof’s drip-edge, allowing water to travel back in the house.
- The sole plate made from composite decking is trapping moisture against the fir deck boards.
- The deck boards were installed too close together, trapping moisture. When they swelled up, the problem was exacerbated.
- Water landing on the more recently added exterior deck is splashing back into the decking of the screened-in porch, causing it to rot.
- The new deck was attached directly to the house with no space, preventing water from draining
- It’s Maine. It’s damp all the time here. Perhaps boards of a shaded north-facing porch just need to be replaced sometimes?
