I have an old porch which is in bad need of repair (or something) I have talked to a few contractors. They all say tear it down and start over. I know they just want the business. My concerns are these: The porch is in okay shape structurally. the flooring and the roof need to be replaced. ( both are original from a redo in the 50's) I think the framing is undersized and it seems like there may be a foudation problem but I can't find signs of sinking. ( one side has a larger gap from the house than the other near the roof.) Also the support posts for the roof don't match up with the foudation blocks. Can I just support the foundation with extra posts? Sould I add more roof supports? If I tear it douwn, where do I start and how? I've never done a major tear out like this before. thanks
