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 faces intersect, running the length of the area."


The ridge area on sloped roof systems are often 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.


The ridge area of a roof system is also utilized for enhancing attic and roof system ventilation. Commonly a ridge vent will be installed in this area. For more information on staying "Green" take a look at our Green Page.


Although a ridge cap atop your roof can be very beneficial, it is not imperative for long living ridgelines. With a systematic approach, the ridgeline's shingles can be installed with prevailing winds in mind.


Prevailing WInds are winds that are fixed in direction and altogether create the natural flow of the planet. If you are near ocean-side, the dominant source of prevailing wind is a light sea breeze. In areas with more variable terrain like mountainous towns, the dominant prevailing winds are sourced from mountain/valley breezes.


The ridge's shingles adjusted to accompany the flow of prevailing winds-


-ensures the natural, dominating winds will not cause upflappings of the ridgeline's shingles.
