Not a book for a beginner do-it-yourselfer. Absolutely no mention of living roofs, sod, or thatch. I found the very small section on Single-Ply Membranes slightly useful, but the other chapters on shakes, shingles, slate, tile, and metal roofing were too complicated for me to absorb at this point. I would probably come back to this book once I have decided on a roofing method and learned more about components from a roofer.
