Re: tying the porch roof into the main house... I'll add I'd also go with 5/8 CDX ply for the roof sheathing. That added 1/8 goes a long way to resist uplift , and as you know wind in your area is a BIG issue.
Patching or replacing roof shingles on a porch is handled in the same way as a typical roof repair and could cost less than $500, but correcting problems with support posts or other structural parts can be a complex job that requires a larger crew and considerable skillâand could cost over $1,000.
