Hi Roland,
I assume you are talking about exposed fasteners. I created that question to test the forum.
In most instances I tell my clients there is a low probability of leakage, but because the fasteners sometimes back out, I suggest they caulk the fasteners when routine maintenance is done on the roof. Exposed fasteners typically are at the top of the roof where water does not accumulate.
Thanks for using the forum.
