I'm building my own home, solo. I will be installing a snap-lock standing seam roof. I have a fair bit of experience with metal roofs...but none with standing seam.
I've been watching how-to videos on Youtube and elsewhere....as well as reading the installation instructions from different manufacturers.
Question on the rake/gable trim: In the attached detail for snap-lock standing seam, it shows the "Z" closure held down with screws at 12" o/c. When the rest of the panels are held down with clips, what keeps those screws from backing out under expansion and contraction in a long run of 34'?
Also, to make things easier, could I screw through the flashing into the fascia instead of using the cleats as shown?
I would simply ask the company that is rolling my panels but they haven't an installation manual nor do they seem overly good on answering such questions.
Hi Arby! Thanks for choosing metal. This is a standard industry gable detail that has been used for years. The screws may loosen a bit over time but they are concealed and I have never seen it be a problem. The biggest concern here really is forcing oilcanning into the panels. You could screw through the fascia but the concern is aesthetics. There are some companies using an F Channel style of gable that does not require fasteners through the metal roof panels. Your panels are pretty long. I'd suggest asking your supplier whether they can provide an F Channel style gable trim.
Thanks, Todd! I couldn't find an example of an F channel on the Net. In searching, I did find the attached detail. Perhaps it is similar to the F channel?
It seems this detail would take care of the oil canning concern....and may be easier for me to install. Thoughts?
That is not quite what I was referring to but I like this detail, especially if you can keep that rivet on top on the exposed side of things (toward the center of the roof) rather than real close to the edge.
