Im Working in upstate NY on a Ranch style home. I'm looking to add a patio roof to the back of this house. The existing roof has a 5/12 pitch, Theres a 12" overhang and its just over 10' high. I would like to extend 16' out by 32' wide. I dont have enough height to carry the 5/12 pitch out to 16'. Theres a shingle roof on the house that I will be replacing with this new patio roof. What is the best way to tie into the existing roof.

by the way the best way to tie into the roof would be to call a roofing contractor for his PROFESSIONAL ADVICE.

Go with an 'ell'. Run a ridge line to existing ridgeline. 2 valleys. Don't even think of a shed roof.

i would tie in by lowering the pitch on the addition to 2/12 or less depending on height you want to achieve.i would use a low slope roof product such as torch-on,rubber or t.p.o.iwould do the tie in by removing the bottom 6 or 7 courses of shingles bring your low slope roof product 18-24 inch up 5/12 roof pitch,replace 3 or 4 rows of shingles keeping your nails high and bond the bottom couple of rows with material compatible adhesive.

Are you asking how to tie the shingles together or the framing?

This should be brought in and valleyed out with the L shape mentioned. If not it will be trouble.
