I bought a house nearly 3 years ago and the patio (normally just cement) had been covered but a half *** job. there was no metal sheet between the house and the cover which allowed rain to seep through. The ceiling was also done with what looked to be wall board instead of ply wood, so when the rain did come in it pretty much melted away the board. I am trying to do it all myself and the one and im guessing the most important thing is that the overall structure is still good. found that out when i was looking for estimates. the patio is about 300 sqft and i am wanting strip it all and redo the whole thing. does anyone have any good websites for steps or know where to start once all the materials have been bought?
