What we’re looking at here is some flashing that would have been pre bent. You can actually buy metal and bend it yourself, and this is actually what I think happened to someone who recently sent me an email, they’re, trying to figure out why the bottom of their plywood is damaged, and I’m showing you this right here. This is what I drew, but I’m guessing that they had a piece of metal and they bent it here also, which would have created more of a problem. I mean it’s hard to get a nice straight corner. I recommend, if you need any type of metal, to go contact a sheet metal fabrication, place, someone who can do this and all these aren’t big manufacturing shops most of the time you can easily find them in your hometown and provide them with the dimensions you need For your sheet metal and have them make it custom custom-made, I don’t recommend bending something yourself.
We used to do this with lead. They used to. Let us we used to have these rolls of lead. Let’S just say was six inches wide and we Stu bend it I’ll, mend it around stuff, and but it’s led it’s not something you’re going to be using anymore. So the question was how the plywood was getting damaged and I’m going to take the rest of the time in the video to answer that question.
This would probably be the most common method. You would have a piece of sheet metal that would go over the foundation, and then you could put your paper and plywood over it. Just something like this. Now, most of the time what I like to see, I’m going to show you a picture of it in the video is a little angle here now I can’t tell you how many times the Z bar is actually bent with a little angle here, but people professionals, Even myself, I’m guilty of it. We push it down.
We want a nice flat, tight corner in here. We end up pushing it down and sometimes when you push it down, you end up pushing this part out. So keep that in mind when you’re installing sheet metal, something like this I’d like to see in an angle to if you have your siding and I apply wood siding here, but the same thing when it would occur with lap siding if it was going to be Made out of a material that could rot now, what we have here is I left about an eighth of an inch gap, but just wanted to give you an idea. I drew some water in here. This would be about a sixteenth of an inch of water.
This would be possible. I’Ve seen water accumulate on level areas plenty of times, and something like this could happen, but if it, if you’re in the right climate and that’s drying out fast enough, something like this isn’t going to be a problem. However, something like this will – and you can see here – I just went ahead and bent the metal up to give you an idea about how water could accumulate if it’s not able to drain off – and this is actually the problem for or the reason why. The person who sent me the email gave me the idea for this video in the first place. This is actually their problem.
They went in whoever and they tried to bend the metal around and they’re, creating a cavity, they’re, actually creating an area for water to accumulate the water is not draining off it’s actually accumulating, and who knows for how many you know who knows how long the water Sitting and again I don’t know what type of a climate this individual is in, but you could only imagine if you built something like this in an area where it rarely rained. Where that, where there wasn’t much moisture in the air you weren’t going to have a problem with moisture, you could you could. This would be a problem, but this something like this is going to be a problem in areas where it does rain enough to create a problem like this. Now, let’s take a look at something I would like to see, and this, of course is the sheet metal with a little angle in it, and we can put the paper over the building, whatever type of waterproofing or water-resistant material, we’re going to use and then, of Course our siding and keep the siding off of the bottom. I like to see at least a quarter of an inch.
You know, especially if it’s sloping, if it’s going to be level you’re going to use level, metal quarter of an inch would probably be fine. Also – and you can see right here – that the water, any water that gets behind the siding is going to roll off any water that gets on the front, is going to roll off the front and down. So something like this is nice. If you can keep the quarter inch trim all the way around great, if not put the plywood on, and you could always nail a piece of trim over just make sure that the plywood trim is up at least a quarter of an inch off of the ground. Don’T forget that if you’re using plywood, this doesn’t occur with lap siding, but if you’re using plywood.
This is also going to provide the building with some type of shear resistance. And if that’s the case, you’re going to need to nail the plywood into the bottom plate. You’Re going to need to have it make sure that this isn’t coming up too far. I would imagine you need to have at least an inch here. I would imagine three quarters of an inch would be pushing it.
Three quarters of an inch might be acceptable, but I’d like to see at least an inch where the plywood, so you wouldn’t want to be more than a half inch off of the bottom of the plate. If you were using a 2×4 that was an inch and a half wide out that makes sense so anyway, this video is the result of a question. Someone asked they sent it in an email. You can send your questions to me. I will be answering them as long as I possibly can.
I would imagine if it gets a little too overwhelming. I will have to stop, but right now feel free to send me your questions and you can find the email address at the website and is home building and repairs calm and if, for some reason, you visit the contact page on the website. And it says that we are no longer answering questions that should give you your clue that you will have to find your information somewhere else so anyway enjoy this free service. As long as you possibly can send me your questions and give me some more great ideas for videos,
