Best way to flash a porch roof
Basic rectangle farm type timber frame. SIPS, house wrap, ventilated cladding, right now thinking furring strips with fiber cement board. This house will have a porch on all 4 sides. Two ledgers for porch, one for roof the other maybe 2' below for ceiling. Would the ledgers be attached right to the SIPS, interrupting the furring strips, slice the house wrap and slip the flashing between wrap and SIPS? That would certainly drain everything out to roof. Cladding above porch roof would still be ventilated. Maintaining ventilation in the section below the ceiling is what I'm wondering about. It could be configured to vent into area between roof and ceiling with the ceiling or soffet ventilated. Would that be an acceptable solution? Any thoughts on vents in ceiling or soffet? Any drawings out there that would show the details would be helpful. That would save me the trouble of doing my own as I am not to well versed on a CAD program.
