We started by creating the footings and built a deck structure that would last forever based on the 2015 international residential code. We needed to cut back the siding to ensure we got a leakproof attachment area for the custom-built roof using GAF shingles. We used 6 X 6 cedar posts to meet load limits for the new GAF shingled roof. We then finished it off by adding cascade steps on three sides and completed the ceiling with gorgeous tongue and groove cedar planks.
