When and When Not to Use Sealant on a Metal Roof Installation

[@carlcadogan4510]

I live in the hurricane belt. The ridge cap when installed has a gap between that and the standing seam roof. Should I be concerned about air essentially pushing under and compromising the roof? I was thinking of sealing all gaps. To ensure full air flow over the entire roof. Which brought me searching for videos like this.

I can't seem to find a video on how to make a center starter for a snaplock panel. Is it possible to manufacture it by hand after the panel is run or do you need the machine to do it? Any help would be appreciated.
