I uncovered a problem, and I think I'll see the same problem (or worse) on the opposite side of the deck. Deck is 16x16 and attached to ledgers on both the garage (where the butt ends are) and the house (one long deck board runs). The ledger is flashed, but the flashing doesn't go over the face board (not sure what that's called). There is no kick out or anything to keep the water from going under the vinyl siding. The water sheeting down the siding has to either drip between the deck boards or run the length and out the end... where there's no clear way out. I'm at a loss on how to properly get the water away from the house. A handyman suggested I take the bottom course of vinyl off, trim it, and install J-channel on top of the decking. I'm unsure how this solves the problem of getting that water away from the walls. I saw a suggestion to drill weep holes in the J-channel so that it can drain, but then the water will be doing exactly what it's doing now - going between the deck boards. 16' is a lot of runoff. I'm not opposed to changing how the siding is in these areas, I'm just unsure how to accomplish what I need to in order to protect the building. I took pictures of two separate areas of the deck - it appears that the metal ledger flashing is only as long as the ledger boards, and stops short of the corner on both ends (smh). When I extend the flashing, how do I deal with the siding? Is there some type of kickout I can use? Is there a j-channel configuration that will get the water from that channel out and away? I've been working under the deck this summer, fixing some other problems, and the ledger boards are in good shape. I will repair the walls and cover the area with house wrap. How do I flash it properly? I think I can find j-channel that will match fairly well if that's what is needed. I'm hoping to not have to take the deck apart.

Siding is cut and sitting between the butt ends of the boards and the metal flashing. This has been working ok - except there is no safe way for any water to get off the edge and out of the channel -- so there is damage. How do I bridge between the deck and the siding to keep water away from the wall?[/i] [img]https://cimg5.ibsrv.net/gimg/www.doityourselft.com-vbulletin/2000x1504/img_5200_1c275f8f92b4e934a3da004a414aad19fd8b1c14.jpg[/img] [i]Left side (garage) under the flap of siding. There's no flashing along the 2x10. Ledger flashing doesn't go over the top of this face board.

Siding has stayed pinched between the flashing and the deck boards without issue (I removed the corner post here), but water can't out past the 90* cut of the siding and is getting to the wall. The ledger flashing appears to stop short of the edge of the deck (not going over this face board) I will remove this deck board and extend and seal the flashing. But how do I get the water to clear the siding? Is there some kind of kickout available?

Very little water can get out of this channel without going 16' to the end, where it's not getting away from the house :([/i] If anyone could help me I'd really appreciate it. I love this deck, but I need to make this right. Thank you for your help.

Hello. We have a 12’ deep by 30’ wide deck on the front of our house and I’m in the process of adding a roof. I’ve replaced all the 6x6 posts that were along the front of the deck so the roof supports go all the way to the ground. They are part of the railing. This will be a lean too roof attached to the house. My questions are; 1) This will be a very shallow slope. Maybe a 2/12 or even 1/12 if I can get away with it’ll. I’m in NW Arkansas so snow load isn’t a major concern. Just enough to shed water into the gutter that will installed. Is that an issue? 2) when I cut the lap splice into the top of the posts to support the rafter beam, is it best to have the cut facing the house or away? Seems like it would be stronger to have the remaining 6x6 material on the outside. 3) birds mouth cuts. Is that necessary for this project? I do plan to use hurricane ties and Simpson structural screws everywhere. 4) is it needed to cut a space for the purlins or can they sit on top of the rafters? I’ve been told to cut out a notch that the 2x4 purlin can set down into is significantly stronger racking wise and we do get some strong winds, but plenty of houses don’t do that and they don’t fly away. thanks for the help.
