Re: Sagging Porch - New Footings?
I would recommend that you have several local contractors come in and take a look. It looks like that whole front wall is rolling outward and it's affecting the porch roof posts, which in turn is affecting the roof. Lifting could cause leaks in the roof, unavoidable, but a certainly a possibility. Main support footings do need to get down below frost line, preferably with a flared base to keep the heave cycles of the earth from lifting the column from the sides.
The framing of the porch itself doesn't look too bad, there may be some issues with the skirt framing and belly band, but for the most part, from the pix, it looks ok.
Will you be able to do any of this work yourself? This will completely depend on your DIY capabilities and tools. This is definitely more of a professional skill level project.
