Hello, I have no experience in roof repair, so would greatly appreciate any comment on my problem. It has been raining hard lately here in Northern California, so the flat roof(?) of the old house I live in started leaking in two places. At one spot, the water starts dripping from the basement ceiling corner area after a couple of rainy days in a row, and not after short showers. Large area of the basement ceiling in that area becomes wet. No visible damage at the upper level right above the leak, but when it was raining there was a puddle on the roof just about above the leak in the basement. The water in that puddle does not drain as the depression in the roofing material is couple of inches deep and about a square yard in area. Quite a lot of seams of tar-asphalt roofing sheets are underwater and do not seem watertight at all. I am willing to fix it myself, so was wondering what my options are as far as getting rid of the puddle. The other leak at the other side of the house is worse as water drips inside the house through the seams in the woodwork at the top of the window, an inch away from the glass, with the paint peeling and the seams turning into slits as the wood takes in water. There are no cracks or other damage on the outside wall above the window. I have found several broken ceramic roof shingles though, which this part of the roof has, about above the leak, but have no idea where and how water gets to the window. I suspect that the water from the roof gets behind the stucco, goes down to the top of the wooden window frame and then damages it to the point that the woodwork starts leaking. Would greatly appreciate any comment. Thanks in advance, h.
Update: with the rain and window leak increasing, I had to cover the corner of the roof above the window with tarp to hide a few loose and broken shingles. The leak stopped within minutes and hasn't returned after a night of hard rain. The leak at the basement ceiling is getting worse with more rain though.
