I have a question about a leaking valley with ice build up? My question is what options do I have for a fix when this spring.

I'm not a roofer, but I bet the ice will melt in the spring.

FlyinFinn >>>> any way I'm hoping we finally get warm enough weather for ice to melt. LOL

What type of roof?

Tear off and reshingle if you have shingles

betting the valley flashing has a hole or two.
what wwc said

Asphalt singles. It is a newer home my son has and it has 3 different levels of roof and where all three come together is where it is leaking in the garage. It also is on the north side and is shaded most of the time but other parts of the roof melt and all run to that spot. It is a melt freeze type event and stops where the sun doesn't hit it to melt it. The home is 5 years old and the first he has seen of it leaking.

Since there's ice it's probably backing up under the shingles. Get rid of the ice you might get rid of the leak.

Shovel off any snow that is insulating the ice from the ambient temps. That way the water will run off as it is supposed to.
The leak is most likely from heat escaping up through the roof and melting the ice, water will take the path of least resistance even up under the shingles when it cant flow down.
Once it is melted off check the flashing. Most times some good tar based patching will fix everything right up.

Appreciate the advise and will call my son and let him know it isn't the end of the world.

Thanks

throw 50 lb bag of softner salt on it

Strip down and put a good quality Ice shield in the valley and re shingle If you are not familiar with it it is a peel and stick to the plywood ,Good product.

You could try removing the shingles and putting a ice and water shield down. Poor design, may have to put warming cords to melt the ice dam.

Exactly....designed to seal around any nail used to attach shingles/flashings. You can also string out a heated wire in the valley and plug that in if it starts to ice dam. They make heated wires for gutters, use those.

^ Wow never heard of such a thing before. That is what I was hoping to see what new product is out there for valleys. I have helped on a few roofs and we would flash the valley then double shingle through the valley. That seemed to work fine. Of course some mostly will take a short cut on the most critical part of the roof.

Thank for the great advise.

Any commercial roofing supply will have Ice and Water Shield adhesive underlayment. I used it a lot in Vermont back in the late 80's for critical areas under wood shake's.

Self-sealing adhesive membrane (Ice and Water Shield) is not new. It's been around for many years and it's a code violation not to use it in valleys and on overhangs in my neck of the woods.

It's going to be a lot of work to tear those shingles off, put the proper underlayment down and reshingle that valley. I suggest useing the heating cable as some have suggested above. Used properly it will eliminate ice-damming.

Is he the original owner?!? I’d be calling my builder on a 5yr old house that apparently didn’t get ice and water shield membrane applied. I see a lot of black jack sealant used instead of proper flashing. . It lasts about 5yrs if you are lucky.

Marty beat me to the punch.

I think it's code everywhere now. I've always used it, even before it was code. Have never had an issue.
