I would like to put a pergola along the south facing wall of my house. The rafter tales are about 7ft from ground level and the roof is tile. If I put a ledger board on the house, the pergola would be too low to walk under. I do not want a tunnel. What other options do I have to support this side of the pergola without using posts? I have considerd fabricating steel supports that mount to the house/rafter tail and extending above the roof line. Has anyone done this? Any links to a how-to, specs, etc? The pergola would be about 3-4 feet wide to cover a walkway and shade the house. Any suggestions/help? I cnnot find anything on the internet that does not entail using a ledger board.
