Thank-you for your patience!!
No, the reason I asked about a contractor was so I knew how much detail
to include. A picture and a few specifications should be enough for
your contractor to be able to build and site design the porch.
Instead of round columns, I would suggest a tapered column about 7-8"
at the bottom and 4-6" at the top on all four sides(without knowing the
exact dimensions of the existing porch, it's hard to give an exact,
because I can't scale it out)
The roof would be an open 2 x 6 (2 x 4 if code allows) rafter supported by an underlaying 2 x 6 ridge support
The outer ends would be supported by a 4 x 4 resting on the columns.
I would suggest the roof decking be 1 x 6 sheathing(exposed below) covered with a shingle that matches your existing roof
The ends of the rafters would be open(no fascia).
The paneling on the front of your house would extend up to the new roof line.
The picture doesn't show it well, but the front of the roof is open,
back to the house(in the picture, it looks like the paneling is in
front,but it's the best rendering I can do)
I thank you again for your "challenge" and your patience!
