Hi, this is Steve from Roofer 911.
I'm at a home in Leesburg, Virginia, that has a couple different leaks. One of them is these two windows here that have hairline fractures at the corners of the sills, so we need to seal the inside corners with polyurethane and that will prevent any further leakage during a wind-driven rain.
The counter flashing up against the wall here is sealed fine. That's no problem, but once we seal the hairline fractures, then the leak is gone. Now, also there's another leak right here in the corner where this roof meets up against a wall and the water is settling at the lowest point, so there's a few different things that's causing the leak.
The first thing we need to do is remove all of the roofing material where the shingles meet up against the wall on the lower roof. Any flashing that's damaged can be either repaired or replaced with new and then we're going to re-shingle that area. Now once that's done, it's going to still leak and the reason why is because of the upper roof here where this roof meets this roof, there's a valley right down the middle.
When the contractors did the roofing, they fastened the shingles too close to the center of the valley and by doing that, when there's a heavy downpour or melting snow, the water is getting underneath that single-cut seam and it's finding an opening through a side of it now and now the water is traveling down the roof in between the shingles and the felt and it's settling down inside the exterior wall between the vinyl siding or between the bricks and the drywall inside and then the water is settling on the lower part of the roof. We need to take up the shingles on both sides of the valley, install ice and water shield and then re-shingle it.
Now once the valley is repaired, the leak is still going to re-occur again, but only this time during a wind-driven rain or a melting snow. The reason why is you have two ridge vents, one here and one over here. If it's not sealed underneath or if the open breathing space is cut too wide, it will leak. We need to take off the ridge vents and then we're going to seal underneath it with polyurethane and then we'll re-install the ridge vent and seal all the fasteners. Once we're done, we've targeted this leak from every possible angle so the leak will not come back.
