Help Regarding Dead Valley


#1

I’m a homeowner with a recurring leak on a roof that originates from an area with a dead valley. It’s been going on for almost three years now and every time the GC and original roofers attempt a fix it comes back a few months later. Also it should be noted that I’m the original homeowner and this is a custom house that is 3 years old.

I’ve attached pictures below to show it as best as I can. While I am unable to get up on the roof to get a direct picture of the dead valley, it’s about 4’ wide with brick on the wall. It also has copper flashing that continues around the side.

Most recently the roofers have put up new shingles around the dead valley, put down a bunch of tar, and used a bunch of caulking between the shingles.

Any bit of help would be greatly appreciated as I’m completely at a loss as to how to get this leak fixed for good. Thank You!

Hi,

Where are you located?

We fix this problem a lot. Each one takes a different remedy.

There may be nothing wrong with the design which means it is installtion error. It may be design error.

Either way you need to find a roofer that can troubleshoot leaks. This will be the hardest part of your problem.

Your Builder and roofer will never find out the problem and if they do stop the leak they will not know how they did it.

Located in Missouri so we do get freezing in the winter, which always makes the leak worse.

I understand 100% about finding the right person who knows how to fix a leak. Recently I contacted an inspector who put me in touch with some contractors who are supposed to know how to fix this. The one we’ve talked to so far has recommended that a copper pan will be needed to fix the problem. The estimated cost of that is $4k.

I remove the shingles and roof in the area with epdm. Up the wall and a good 5-6 feet up the roof past the valley.
Then shingle over leaving 2-3 feet of epdm exposed above the valley.
Never had a call back yet. But then I know epdm where as most shingler’s wont.
And I think dead valleys are a design flaw.

I agree, not the most apealing on the eyes but it will fix the problem.

Might be able to use the peel and stick Modified with a matching color, just depends on how much of a dead valley there is.

bottom line is you have a ton of water slammin
into that wall.
so yes get the area torn out, install a new flat roof product in dead valley area.
do not put L metal and conterflashing on the wall, cause the force of water hitting wall will push through. you have to roof up that wall at least a foot. also raise shingles and valley bottom up out of the dead valley, so they are not laying in the water/snow

gweedo.

My guess from here? Needs more carpentry then your everyday saddle.

Copper
PVC,TPO,EPDM
Are your best choices for an area like that.
And a very good experienced roofer who charges enough to do a good job.
