HAIFers, I have a small leak on a portion of my roof that is flat and about 12' x 12' (master bedroom). I only need a quick, provisional fix since, in the long term, we likely will build a room on top of that master bedroom. I am considering doing this provisional fix myself. Does anyone know any website where I can quickly educate myself on what is involved such as what are my options for materials, price, risks, etc. You help is greatly appreciated.
