End Wall Flashing

Quinn

Any advice on how to proper flash a gable porch roof where the roof meets the side wall of the house? Vinyl siding is going to be put on after the roof is built, but is there a good method to flashing to keep the water from running down the roof and behind the siding?

One thing I always do is when the last full coarse of siding comes up below the roofs edge, stick a nice wide flashing behind your first step flashing and let it out over the nailing flange of the siding at least a foot out from the edge of the shingles. Any water running in the J-channel will be forced out over the siding lock and not behind the siding. I use this detail anywhere a j channel ends, water belongs on the face of the siding.
You could also do a fancy bend at the bottom of the first step to force water away from the wall.

Thanks guys , That really helps. I build a lot of decks and some porches, but any time I tie a roof into a wall like that it always bothers me if I'm doing it right. Most porches I do are roof to roof. I will be sure to take your advice.

I thought I was the only one to do that....Unfortunatley down the road you see a water line where it weeps out but its better than rotting out a wall.

Kickout solves that Tom

i do that also,then the kickout.Its the layering of protection thats important in critical areas

I agree, water behind the siding is a bigger problem than the evidence that the flashing is doing it's intended job. look at the octagon on the right where it meets the garage roof, that whole area got Ice and water shield down to the foundation as well as coil flashing detail. I didn't side the house, but I framed it. I felt the responsibility to make sure that area got the special attention it deserved.

Kick out or a step that exits out of the siding. I'll cut an opening in the siding if necessary. You may get some idea here, http://www.albertsroofing.com/Window%20Flashing.htm. Though the first page details proper window work, the technique works everywhere.

The simple fact of the matter is that a kickout will work great on one wall, and not as well on another. Each case will have it's own rule, depending in where/how the siding ties in at the bottom. If you have to cut a chunk out of a piece of siding for a kickout, you may be creating a place that relies on caulk.

a kickout does require a special cut not sure i understand where you would have to caulk tho Frank?

I've seen it, the roof, end in the middle of a flat section of siding and the cut couldn't be counterflashed. Kinda weird. It resulted in a vertical cut, that needed caulk on the top. Just something I've seen a time or two. I looked them over, but can't remember if i saw a better mousetrap those times or not. Me, I get creative if I have to.

I always kick out whenever there is a step flashing. I dont cut verticle, I cut on an angle that favor water run off. I may have to angle cut the shingle starter or jump out past some foam but I get that water out.

One thing I do that I refered to earlier in Loneframers post is; I run aluminum down over the lock on the course below when I dont use channel just as a precaution. For instance back in post #5 crown buts the siding jay. If that weren't crown and that fascia received a gutter I dont jay. I dont like how the gutter stays off the wall away from the kick out above. I'll make a large aluminum flashing the goes over my nailer below, under the kick out above and return along the fascia it butts against.
