Protect that expensive roof during installation
When working the metal roofing panels into the valleys, the bottoms of the panels slide into the valley flashing and are hemmed with a mallet.
But this can scratch the panels before the roof is even finished.
Ben’s solution is to slip a scrap of starter panel between the valley and the roofing to protect it from scratches and whacks.
This way, the new roof still looks new after you finish it.
