Best quality fasteners for exposed screw metal roofs?
It seems that the biggest issue with exposed screw metal roofs (as reported by the internet) are the fasteners, or the gaskets around those fasteners. Supposedly you can avoid a lot of problems by buying better quality fasteners with better gaskets.
Does anyone (especially metal roofers) have recommendations on what a high/best quality screw is for exposed fastener metal roofs?
