New Construction Roof Leaking


New construction roof started leaking last week during a rain storm. Water was leaking from a light fixture in the ceiling. Spoke with the builder and he had his roofer come by. Their fix was to caulk up some locations in the roof. Please have a look at these pictures and tell me if this seems like a reasonable fix for the issue.

New Construction Roof Leaking


Put your foot down. Using Blackjack to fix a poor roofing job, is just looking for failure.

Tell the GC and roofer, that if they do not do the fix properly, which will mean most likely a tear off and doing it correct, with Grace Rain & Ice, 30# felt, laying the shingles per manufacturer specs.

Have you looked in the attic for mold issues yet?

If the GC does not want to fix the problem, start working with a lawyer. Keep documents and photos of everything, in case it goes to arbitration, due to the GC will not fix their shortcomings.

If the roof is leaking, who knows what other short cuts they took.

I see a bigger problem.

As that rain water goes flowing down the roof shingles....when it gets to those ridge caps, it's going to want to flow up under the cap. If the underpayment is not continuous, water gets in.

I'm. Not the expert, but besides this not being the best design, I'm thinking that a modified valley flashing should have been used.

That is one really odd roof line.
Can you take a picture, like standing in the yard so we can see the whole picture.
Just makes no since to have two roof lines off set like that to me.
Was this an addition, or a whole new house.

Can you elaborate a bit more on what a modified valley flashing is? I intend to discuss this repair with the builder and want to be as prepared as possible.

To me that just makes no since the way it was framed.
That roof should have been flat all the way across with no offset like that.
I could almost see if they offset it by 6" and ran it like two separate roofs, but not like that.
Glad I'm not the owner. If I would have seen them going up on a ladder with a caulking gun on a brand new roof I would have ran them off the property.
Only place that should have needed sealing is the exposed nails at the end of a cap run.

This is a cheap way to fix an inadequate roofing job. I think they cheeped out on the ice and water shield. Get another independent roofer to come out and evaluate the stituation why house is still under warranty.



ps. I also don't under stand the offset on the ridge.

In that first picture it sure looks like the caps where run backwards.
I do not see where it is in the other pictures.

Contact the manufacturer of the shingles, and have them send someone out to look at that job. Also before you signed off on it, did you have a Home Inspector go through, to find any and all issues?

Get on the GC, and do not let up. If they start leading you on a goose chase, by not answering your calls, etc., start sending them certified letters, with the part of the contract that they gave you, that covers this problem.

If they start ignoring you, I would not hesitate to secure a lawyer to start placing pressure on the builder. Has your state or local home builders association ever have complaints about this builder and their sub's? Any complaints from other customers of theirs?

No question about it. That will keep leaking. They should at least have done it like a geodesic dome section. Run the lower up and over the ridge, run the other side over 3" and cut it off.

Alternatively, they could have run the upper and cut it flush, then run a modified valley up and over like termination flashing on the upper side, held with cleats, and normal valley, or even a channeled valley on the other.

Channeled valleys beat the dog out of W valleys in many applications.

I have always called those "zippers".

I must admit thats about the smallest one i have ever seen.

That "fix" is laughable, I would never allow that to fly on my roof.



I cant decide if that red valley on that slate roof or the henrys on the ridge looks worse.

The red valley is 120 years old. They seldom use 'soakers' around here, so you have to point the ridges every couple of years and recover any exposed nails.
Not many want to pay the $130.00+, per lineal foot to redo the ridges correctly with soakers.

Oh, tropical rain that could jump a 'W' valley would just be turned away with a channeled valley.
