What is a ridge cap?
Ridge cap is a particular shingle that was created to withstand the severe wind that blows across a roof’s ridge. It is not only thicker than a standard shingle, but it is also pre-bent to avoid cracking when folded over the ridge. Ridge cap is made by capping/nok roll forming machine
Shingles placed along the roof’s highest point protect the joint where two slopes meet, helping to block rain and melting snow from seeping inside. Since they are bent over the ridge, this section often wears out more quickly than the rest of the roofing surface.

Roof capping comes in two main styles:
