Installation Guide

4) Repeat steps 1-3 on the opposite side of the roof. Make sure
fasteners are properly seated on the material.
5) Place the first ridge cap on the gable end of the roof overhanging
3”-4” and then place the ridge closure strips under the cap at least 1”
from the bottom edge of the cap. Fasten the ridge cap down at each
corrugation ensuring the fastener also penetrates the closure strip to
hold it in place.
6) Minimum of 3.5" overlap, increase as needed to ensure
penetration of overlapping layers.
7) At the end of each ridge, cut the overhanging portion along t
he
crown and fold down flaps as a weather guard and fasten to the
fasc
ia.
HINT: In temps below 55 F, warm the ridge cap up before folding.
