[RE-wrenches] Metal roof/self taping screws

[Jay]

Hi Jerry 

I thought about it. 
But they are $5 each
Not rated for L feet
Have 4 holes vs 1 hole
There is no underlayment as it’s a barn

Using polybutylene tape and or caulk, it’s a pretty solid way to keep water out and with the self tapping bolts is more secure to me ( thanks Allan).

The parts that William suggested are designed for metal roof over wood substructure, not applicable in this case. 

I’ll just look for the right self driving lag bolt

Jay
