Fun and adventure in Eichler-land: We've had a couple of battles with leaks lately -- nothing too serious, but annoyances that required analysis and fixing before they led to worse things. The first to make itself known was an occasional drip from the master bath's vent fan. This was difficult to diagnose, as there is an identical dripping that results simply from condensation on the fan housing when one takes a steamy shower... but copious rain produced a clue. Complete disassembly and removal of the fan revealed some very wet wood, a real surprise considering that the entire roof is coated with a thick layer of (supposedly) waterproof foam! Well, the water was getting in there somehow, and with more rain on the way Chad quickly engineered an impervious multi-layer barrier, complete with articulating fan door. It has now withstood several intense rains and fierce winds, with no water penetration.
Leak number two appeared as a water stain on Nimue's bedroom wall -- apparently, the roof drain adjacent to her wall clogged up enough to let water pool up (normally not an issue on our sealed roof) and it somehow wicked back around the drainpipe into a joint between the outer sheathing and the roof. This spot is normally sealed with caulk, but this particular drain was placed a little closer to the wall than ideal, and was never caulked behind the drain pipe. Chad filled it in, and so far so good, the leak has not re-appeared despite some real downpours.
