Folks,
What is the best way to attach a patio cover ledger to a stucco wall?
It’s the wet side of the house, so I don’t want to disturb the stucco any more than I have to.

Hi Bear,
Probably predrilling through the stucco and lagbolting to the framing members underneath it. Vulkem 116 could be used to seal the roof to the stucco. Vulkem is a urethane based caulk of high quality. While caulk sealing is usually imperfect it would not damage the stucco.
Do you primarily work on boats?

*Bear, Have you considered making it free standing and then caulk between it and the house? Skip
*You probably don't want to hear this, but if this cover is meant to be a permanent, waterproof addition to the house, cut the stucco. Lag the ledger to the wood frame. Flash from under the stucco above, then out over the ledger and finish roofing. I don't know what structural or wind loads are for your cover, but I'd be afraid of cracking the stucco with a surface mounted ledger.Dave
*Bear I totally agree with Dave. Cut the stucco, secure the ledger board to the framing behind the stucco wall and flash just like he said. By golly, we have some very good people out there willing to give great advise. Neil

You don't describe the situation well enough to picture where and how the existing roof comes into play. If you'll add that information you may get more specific and helpful answers and you may not have to cut the stucco, a fate to be avoided unless you own a life support spacesuit. Even then you'd be saying,"Ugh, what a struggle and a mess and dangerous too. Never again if I can help it!"

*Folks,Thank you for your input.I have two 8' patio doors separated by a window, so I suspect that there is a 4x header the whole length of this end of the condo. It's in Newport Beach, CA - so there is more sun than rain. Drought this season again - but winter of 97-8 was sandbag time, so it can rain hard and heavy.As noted, this end gets the wind-driven rain, so I am very leery of cutting stucco to flash. Just my luck to let in the rot. The patio cover is designed to be a sun shade - not a waterproof cover. The loads are small - either 2x4s for shade or lattice panels. There is a fascia running above the doors. My thinking was to secure the ledger to the header by using HDG lags, 16" O/C, with PT ply standoffs on the inside surface so air circulates. Lots of caulk (which I don't rely on) or LifeCaulk (which I do - it sets up under water. Use it on the boat.), Everything prepainted before assembly.Flash the ledger up the stucco (-2") and tuck under the fascia. That should keep most of the rain from getting behind the ledger.What do you think? Buy a sun umbrella and call it good?Materials are another issue. Green DF, redwood construction heart on down, some fairly nice PT stock. Have not seen much cedar. Herself, on hearing that I could buy a PT 2x6-16 for $11 or the same in RW heart for a mere $27, suggested that redwood was not on. As I recall, it was, "In your dreams!" I suspect that PT will be it. Should have taken her to Ganahls and showed her the RW 2x12 for $208. Nice stick of wood. Clear heart. (At that price it better be.)ToolBear
*OK Bear, You say you have a fascia and you will be placing the sunshade under that, right? Are there any rafter tails sticking out of the stucco behind the fascia? If so and this is truly a light weight design, you could hang your new frame off of those tails and not have to be concerned with lagging through the stucco. Otherwise your plan appears to be well thought out. I would look for a sealing washer to put on the lags between the blocking and the stucco to help seal your super chalk job. Best Wishes, Peter
