Telescoping ridge vent

Abstract:

Ridge vents are configured to cover an open ridge of a roof and allow a flow of air to exit from the open ridge through the ridge vents. The ridge vents include a projection and a projection receiving area. When a first ridge vent is secured over a ridge opening, the projection of a second ridge vent is at least partially receivable in the projection receiving area of the first ridge vent.
