Its shocking how many rural Iowa residential metal roofs are exposed fastener. Poor folks are in for a bad surprise.
I am in philly suburbs, there are guys around here selling exposed fastener roofs on half million dollar houses and selling them as 50year roofs. Love to drive past and see how many screws they put in the valleys.
Around here they are even worse. They sell them as “lifetime” roofs here. I install them too from time to time but am totally honest and say I’d rank them the same as a low end shingle.
