TL;DR
A ridge cap shingle is the folded shingle unit that covers the peak where two roof planes meet, lapped along the ridge to shed water in both directions and finish the roofline. Manufacturers make dedicated high-profile caps that flex without cracking and stand up to the concentrated wind exposure at the peak; cutting up three-tab shingles is the budget substitute.
What it means
A ridge cap shingle is the folded shingle unit that covers the peak where two roof planes meet, lapped along the ridge to shed water in both directions and finish the roofline. Manufacturers make dedicated high-profile caps that flex without cracking and stand up to the concentrated wind exposure at the peak; cutting up three-tab shingles is the budget substitute. Over a ridge vent they are fastened with longer nails, and they are typically the first pieces to fail in a windstorm.
