Hi - I'm in the process of having a standing-seam hidden fastener system (Ideal Junior HF) installed by a contractor on our garage. The attached photo shows a couple of areas that I'm not sure have been done correctly. He's told me this is "just how things are done", so I w would value some advice and opinions from other installers:
Ridge cap: in the area where the pitch of our roof changes for the shed dormer, you can see that the ridge cap is bent up to accommodate the different angle. Its a vented ridge, so there is mesh underneath - I'm not so much worried about things getting in as I am that it is unsightly. He says it is the only waterproof solution. I suggested cutting a slit in the ridge cap at the transition point so it could lay flat, but he says this would let water in. Thoughts?
Some of the panels are bowed up. He says the panels can do this in cold weather and it will sit flush on the roof deck in summer, but it seems like a big opening for either driving rain or insects to get into.
Exposed ends of seams (and panels for that matter) Are these typically capped or sealed, or left open as in the photo (again, it seems like an entry for pests) and moisture).
Thanks in advance for any insights.
I am opening this up to see what other comments are out there. I would also suggest contacting the roofing manufacturer for their input. My thoughts are as follows. Based on the type of ridge cap and the construction of the house, this may be the best they can do. It might be possible to adjust it for aesthetics a bit. Regarding the bottom of the panels, it is not unusual for panels to crown a bit in the center but my preference would have been to have hemmed the bottom edge of the panels over the starter / drip edge. As far as the rib closures, my recommendation is to leave them open. Some folks though do try to close them but usually end up with an unattractive maintenance issue. Is that a snow bar running horizontally?
