I used to have a house with flat roof. if and when I got a leak I just used tar and associated materials. now I just bought a house with a slent shingle roof. there is two coats of shingle. and a leak into the garage that seems to also make its way into my living room. apparently the leak is located into a galley.how do you figure out where the leak is? and how do you repair it?
clearly I could call a roofer and have it repaired or have a new roof installed but I don't think that I can afford it.
thank for any advice.paul
