Adding porch to existing roof
I am building a home and had trusses built for the main portion of the home but will be stick building the front porch. I have designed and built the home to the point of dry in and roofing but cant find any info on how to construct the front porch roof. This must be done before I can put the shingles on the roof. The porch is 16ft long and 8ft wide.The pitch on the main roof is 6/12. The porch will be gabled on the 16ft outer edge. The home is a one story ranch style. The main roof has been trussed with sheathing and rolled roofing paper applied.
Does anyone have information or a website addy or a book suggestion that would tell me how to go about adding the porch onto the already sheathed main roof?
Something with a diagram or very detailed description would be great.
