I had a galvalume metal roof installed by a contractor on my new house, and i'ts been leaking around the dormers where the valley's meet the main roof. It's taken me six months to get the contractor to do anything about it and when he finally did he just used some permathane caulk sealant. They just cut a notch in the main roof panel and the valley trim extends down through it. I don't see any was this will work and it looks wrong to me. I've enclosed a pic. from the inside showing the end of the valley trim stiking through the roof. I don't think the sealant will last long. I'm also concerned that they only atached the panels on 4 foot centers instead of 2. Am I correct about this being wrong or is it accepted practice? thanks in advance

You have an R panel on open framing with dormers. YUCK! A picture of what it looks like on top would probably be more helpful. I know that R panel can be installed on up to 5' centers over 16 GA steel purlins. The less exposed fasteners you have the better. Your concern is uplift, which will probably be pretty close to the max at 4'. Concentrate on that valley detail. The valley end should not run under the roof panel that it should be feeding on to.

Their are 2"x4" lathes on 2' centers, but the contractor only attached the metal to every other one. Maybe that's ok like you said less exposed fastners. The top corner of the w-valleys are just tucked up in a slot cut in the main roof. It seems to me this should be 2 seperate panels at the end of the valley with an overlap. Here's a pic of the outside if I can get it to upload.

Here's a pic of the light shining through before he pust the caulk on it.

You need a replacement panel there. That is a workmanship error. The valley should flow onto the panel not through it. I hope that you can reach settlement on that.

Thanks that's the way I thought it should be done. I held out $500 and don't intend to pay it until the valleys are corrected.
