You walk past the torn out shower every morning, brushing your teeth in the kitchen sink because the only working bathroom is now a pile of backer board and dust. The contractor said a few weeks. That was a few weeks ago.
You went up to clear the gutters and found a pile of what looks like coarse black sand instead of leaves. Or you noticed a faint brown ring on the bedroom ceiling that was not there last fall. That uneasy feeling is your gut telling you something is wrong overhead, and it usually is.
