Abstract
A ridge vent for tile roofs is provided having a vent strip located on each side of a roof ridge. The ridge vent includes a center water dam having a centering portion and two leg portions, with the centering portion being located over a ridge board. The vent strips includes a vent material, formed from a non-woven mat, including a first surface, which matches a surface of the tile roof, and a second surface. An upper water barrier is attached to the second surface of at least one of the vent strips and extends over the roof ridge. The ridge vent is rollable and can be provided as one piece or as separate components.
Claims19
A rollable roof ventilation system for a tile roof having a roof ridge, comprising:
- a center water dam assembly configured to be located over a ridge board, which includes a top, a first outward facing side, and a second outward facing side, the center water dam assembly comprising a ridge pole cap configured to be located over the top of the ridge board, a first vent strip, a second vent strip, a first lower water barrier, and a second lower water barrier, the first vent strip configured to be disposed on the first outward facing side of the ridge board, the second vent strip configured to be disposed on the second outward facing side of the ridge board, the first lower water barrier secured to an upper portion of the first vent strip and comprising a first flange configured to fit the pitch of the roof and be secured beneath a first nailer board on the roof, and the second lower water barrier secured to an upper portion of the second vent strip and comprising a second flange configured to fit the pitch of the roof and be secured beneath a second nailer board on the roof;
- wherein the first lower water barrier comprises a down-turned portion or a hooked portion on an end of the upper portion of the first lower water barrier and the second lower water barrier comprises a down-turned portion or a hooked portion on the end of an upper portion of the second lower water barrier;
- a third vent strip having a first surface configured to be complementary to the tile roof, and a second surface generally opposite to the first surface;
- a fourth vent strip configured to be located generally parallel to the first vent strip and on an opposite side of the roof ridge with respect to the first vent strip, and having a first surface configured to be complementary to the tile roof, and a second surface generally opposite to the first surface;
- and
- at least one upper water barrier connected to at least one of the second surface of the third vent strip and the second surface of the fourth vent strip, and extending therefrom toward the roof ridge,
- wherein the first vent strip, the second vent strip, the third vent strip, and the fourth vent strip are comprised of a non-woven synthetic material, the first lower water barrier and the second lower water barrier are comprised of polyvinyl chloride sheet material, and the at least one upper water barrier is comprised of closed cell foam, polyvinyl chloride, or polymeric sheet material.
A method of improving ventilation to a building comprising a roof including at least one vent slot disposed along a ridge board, and a plurality of mating tiles overlying the roof, the method comprising applying a water dam assembly having a centering portion and two leg portions over the ridge board, applying a first vent strip to the roof, the first vent strip including a first surface which conforms to the mating tiles and a second surface having at least a first upper water barrier attached thereto and extending therefrom, wherein the first vent strip is aligned generally adjacent to the roof ridge and wherein the water barrier at least partially bridges the roof ridge;
- applying a second vent strip to the roof, the second vent strip including a first surface which conforms to the mating tiles and a second surface, wherein the second vent strip is aligned generally adjacent to the roof ridge on an opposite side from the first vent strip.
