Pergola Roofing - Dusty Workshop - 09-25-2020 Good morning I am building a pergola over our patio. It is roughly 15x15. there will be 6x6 posts at the corners and middle of each side. in order to have a 7ft heads pace at the low end, the rafters, purlins and corrugated polycarb can add up to no more than 6 inches. The posts on the house side are supporting the dining room (which used to be a deck) and the dining room overhangs the post by 2ft. So the high end needs to fit up under this. So I could use 2x6 rafters and notch them out for 2x4 purlins. I am wondering if I could use 2x4 rafters and 2x4 purlins in a 12x12 grid layout. That would be more wood but not all that notching. I know 2x4 can span 8ft. does this sound like a viable option? Thanks |
