Capistrano Bird Stop / Eave closure is a metal riser that has holes, called weep holes, which allow any moisture to exit the roof. These closures, also known as "bird stop", help in blocking any infestations from vermin and birds alike. When installed properly, an eave closure can elevate the tiles at the eave to the proper height, and give your concrete tile roof the perfect finished look.

There is also ventilated eave closure that has specially designed openings that allow air to flow in at the eaves and under the tile to help cool the roof.
