Closed valley leak
 
2 Attachment(s)
Couple pics of a valley on my roof that is leaking down into the soffit. One of the pics attempts to show how there is a very tiny hole at base of valley. Is this not correct? How should it have been done?

I've been told that this hole is source of leak and entire valley must be reconstructed. Thing is, valley on other side is done same way but no leaks there.

Just seeing what others thoughts are.

Let's see.
Cut side isn't 2" out from center.
No pipe collar.
Nice hole in the end of the valley where that shingle is cut.
I seriously doubt the cut side has the shingle tops cut off either.

I forgot to add, No flashing on/under/into that short sretch of fascia either.
I'll bet the other side comes to grief too if the same person did it.

Pipe collar is getting corrected.

How do I go about correcting that hole? And checking the shingle top issue?

Which side are you referring to? Or is that the hole into the roof at the corner there?

Would a potential solution be to remove a few rows of shingles so I can install flashing into that hole, the reshingle?

Other side is the same, but no leaks

Pull 3-4 shingles on the l. side. Install flashing under the shingles/behind the fascia all the way to the valley apex.
Remove and replace the cut shingle. It goes under the ones from the r. No cutting.

Start at the top of the valley and each shingle must be lifted ant it's top cut paralell with the rafter,ie straight up.
Browse my site. See the pages about chimney and step flashing, the valley pages, the power vent install, and any other that might be pertinent.

Look closely! If any of the shingles from the right have a butt-joint within 6" of the valley, it needs to be corrected!

Should have put ice and water shield on the valley.

What is up with that crack on the lower shingle?

Where is the boot on the pipe collar?

My recommendation is to have the valley pulled and reinstalled and here is why,

Serious rookie errors:

1.)Pipe flashing.

2.)Improper lace of a closed valley. #1 IMO possible cause.

3.)Possibility of no step flashing in the wall area under the eave.

4.) Like Tinner said valley cut is more than the required 2" out. (Not likely IMO to be the cause of your leak but shows rookie roofing.

5.) Like Tinner also stated points left in the valley.(Not likely IMO to be the cause of your leak but shows rookie roofing).

6.) The drip edges is squared up possible cutting into the shingles dormer side.

IMO it comes down to piece of mind,meaning,knowing the problem is fixed or wondering if you found the cause.

I would hire a professional contractor you trust to have the roof inspected.

I pull apart several every year will storm shield in them. If the roof installation is worng, it won't help one iota.

On the same token, I've removed many a roof that lived a full life and didn't even have felt in the valley, nor had they leaked when the roof installation was correct.

Thx all. Turning this one over to the pros. I don't have enough experience with roofing to try and monkey around with a complicated valley. Better to let a pro do it and know it's fixed.

I can't argue with that, but it's better to have ice and water shield than not.

Many people have leaks and just don't know about it b/c they never venture into the attic. This is especially the case for those with cellulose insulation which would absorb any water that gets through.
