Hi, this is Steve from Roofer 911.
I'm on a roof in Herndon, Virginia, and they have a leak right down here, right down at the corner. I noticed there's a quite a few different things that's causing this leak. Now, one of them is a satellite dish support plate. We need to remove this and then we're going to re-shingle this area.
Also, this gutter was clogged with debris. I cleaned it out a little bit, but I got to get it all out. Because the gutters, when they're clogged, they can cause water to overflow over the back and inside the home.
The biggest problem is here. All this flashing here up against the wall is wrong and you can see there's a nail exposed here and it's like this with every single shingle along the wall. What we need to do is remove all the roofing material where the roof and the wall meet, and then we're going to repair or replace any of this damaged flashing and we'll re-shingle this area.
I wanted to show you something. All right, the nail is right there. That nail should be not exposed. There should be no nails exposed in the flashing at all, but instead, this nail here should be holding this flashing underneath this one here, so this way, this piece would be overlapping the nail and the customer would not be having the leak.
Now, being that the leak is at the lowest point, I needed to check everything above, and that includes the siding. I wanted to make sure that all these panels are overlapped sufficiently enough, and sure enough it is so the vinyl siding is good.
I wanted to show you something else. Now, here, where the roof and the wall meet, they did the same thing. There's nails exposed in the step flashing, so we need to take up all the roofing here, repair or replace any damaged step flashing, and then re-shingle it.
Now, another thing is if there's a driving rain, I noticed two other things that could cause that leak in the corner, and that's possible hairline fractures to the inside corners, so what we would do here is we would go inside the home and then we would seal the fractures with polyurethane. Fractures can occur during normal expansion and contraction.
The other thing is the ridge vent up here is brought all the way to the eave. Now, that's a problem only if the contractor cut the open breather all the way to the end, and if he did, if there's a driving rain the water will get in through the side of the ridge vent, then the water will travel down the roof, in between the shingles and the felt. The water will settle down inside the exterior wall and then leak down here at the bottom of the valley.
Now also, this satellite dish, I see that the mounting plates were never sealed, so we're going to seal the bolt and seal around the mounting plates with polyurethane. Once we're done, we targeted this leak from every possible angle, and they will not have this leak again.
