Q. I remodeled my 1926 Cape style house in 2005 and had a screened porch built, using heavy (3/4 inch) cedar shakes on the shallow roof. Since then, whenever it snows, I have a small leak, which no one can find until one man said the roof would have to be partially removed to find it. I don’t want to do that. The leak stops when the snow melts, and when water enters, it falls harmlessly on the bluestone floor, and it is not a bother. Alternatives?
