I have some old 1970's-built sectional concrete garages that have very leaky asbestos roofing sheets. I thought about coating them, and had a chat with a local builder about the options. He said that replacing them wasn't as big a job as I had thought and would get rid of the asbestos problem once and for all. Because I wanted to also eliminate any condensation issues he suggested going for a timber OSB sheet replacement , covered with EPDM rubber sheet. He reckons it would be reasonably economical to do and is preparing a quote for me. It might give you an idea of what an alternative approach might cost?
