The ridge of a sloped roof system is the horizontal top area where two sloped roof areas meet.
The National Roofing Contractors Association defines ridge as "Highest point on a roof, represented by a horizontal line where two roof areas intersect, running the length of the area."
The ridge area on sloped roof systems should be capped to ensure a watertight roof system as well as aesthetic appeal.
There are different options on what can be used for ridge caps depending on the system in place. Shingle roof systems usually have ridge accessories such as ridge shingles.
