Hi, this is Steve from Roofer 911. I'm at a home in Vienna, Virginia.
They have a leak that's right in this area here, all the way down to the bottom of the valley. I noticed a few different things.
The nails over here at the valley centerline, they're placed a little bit too close. If there's a heavy down pour or a melting snow, the water can very easily get underneath this valley and wherever the nails are fastened too close to the centerline, the water will seep right through the sides of the nails and into the house.
A lot of times, the water will keep on traveling underneath the shingles on top of the felt and they will just settle anywhere down below. What we need to do is remove all the roofing material at both sides of the valley here, approximately 3 feet on each side. We're going to install Ice & Water shield right along the entire length and then we'll re-shingle this area.
Now over here up against the wall, it's a very tight fit so I cannot check the overall condition of the flashing. We need to remove all the roofing material here, any flashing that's damaged can be either repaired or replaced and then we're going to re-shingle this area.
Now another thing is we have a ridge vent and I cannot tell how wide the open breathing space is because they have a cathedral ceiling inside. It is very possible that the open breather is cut too wide. We need to remove all this ridge vent from about right here, straight up and then we're going to install Ice & Water Shield underneath but make sure we don't close the open breather and then we're going to reinstall the ridge vent and then put new cap shingles.
Also, it looks like the ridge vent is coming up ever so slightly. No, okay, it just looked that way. That looks like about it.
Another thing very important. We need to lift every shingle where the shingles join together going across the roof because these contractors, they use roofing nail guns. Now with a nail gun, you can fasten 5 to 8 nails a second and if they didn't pay attention to where they placed each and every nail, there'll be nails exposed for example here, at the joint even though this shingle here is good but 1 nail exposed in the joint, that will cause a leak as well.
We need to check the upper roof from the bottom of the valley straight up to the top to see if there's any nails exposed at the joint as well because the water can originate from up there and then travel down the roof and then settle on the lower roof.
That's it. Again, my name is Steve, Roofing 911. If you have any questions, I can be reached at 703-475-2446. Thank you.
