Hidden fastener – standing seam Menards metals roofing rake trim

| Posted in Construction Techniques on
Hey everyone, I just ordered hidden fastener metal roofing from Menards. The reason I ordered this stuff is because I did not want a chance for the exposed fastener screw gaskets to leak overtime not only from deterioration but also from expansion and contraction. The screws going into a slot in the hidden fastener type roofs allowing the panels to move with hot/cold weather. I am going to hem the eaves. Now on the rake trim, Menards wants me to screw it right through the roofing. Not only will that defeat my water right seal, it won’t allow the roofing to move and it will buckle I think? Anyone ever run into this issue? Ideas? Thanks!

Trims that are parallel to the ribs should be riveted to the panel through a layer of butyl tape to allow for expansion. This is usually accomplished with a piece of z riveted to the panel at the rakes and then the rake trim hooks onto the z and is screwed or nailed to the fascia. You can also run drip up the rakes and hem the edge of the panel to hook over it but that usually requires access to a long brake or Wuko Bender. The system you’re describing sounds like a hybrid system that allows for some exposed fasteners, but you can still use the system I mentioned above.
Thank You! These are the ideas I was looking for. I will check and see what type "Z" pieces they offer, or maybe even just use some coil steel and make my own!

The concealed mount can be very user-friendly. Moreover, hidden fasteners are convenient when your roof looks new and bright. Fasteners made of dark materials are most often conspicuous, and your neighbours begin to ask what it is they see near the corner of your roof.
