How to install standing seam roof where 2 valleys fork

Hello, We have just had a standing seam roof installed and it does not look right. We went with a metal roof because we have had ice dams on this section of roof (we live in Vermont). In the photo you can see a valley forks into 2 valleys. The seams on the small triangle have the upper end open to water coming down the right side valley. Is this OK? How is a metal roof supposed to be installed in this situation? What should we do to fix it now? Also the contractor did not have the correct vent boot when he installed the roof so he proposed to put on a type of boot that is put over the top of the metal roof and screwed down. Is that going to develop leaks as water gets under the edge and freezes? Thank you very much for any information or ideas that you have! Regards, Tom

You have a very unusual roof configuration where you have valleys, pich chanches and roof angles all converging. The photo is limited in the detail to answer your question however I can point out that he hemmed the panels into the valley which is correct. If it is not leaking then it is quite possibly done correctly however the top ends of the lower seams should be hemmed closed where it meets the upper roof at the transition. I would discuss it with your contractor and complete a water test and if you have concerns agree to a small hold back for a period. The post applied screw fastened boots are quite good and is what we recommend as you do have movement at these locations and they have a history of working well.

Hi Allan, Thank you for your help! How is a seam hemmed closed and can it be done after the roof was installed? Regards, Tom

Yes it can be hemmed closed after installation but it is differant for each profile. You need a metal roofing contractor to complete this if not done and I would encourage having your contractor do the work as he is warrantying it.

Hi Allan, OK, we will ask him to do it, he still has the boots and some painting over scratches to finish anyway. Thank you for your help! Regards, Tom
