Ventilation system for roof

摘要

A roof vent and a roof structure are described. A roof vent can include a baffle with a cross-section where a first portion extends upward from a bottom plate and a second portion extends from the first portion to define a space between the bottom plate and the second portion. A roof structure may or may not have a roof deck, and comprises a plurality of roof cover elements with a radiant barrier layer underneath the top surfaces of at least some of the roof cover elements. In another embodiment, a roof structure may comprise more sheathing layer vent members than roof cover layer vent members. In yet another embodiment, a roof structure may comprise a layer of roof tiles with at least one vent member, the vent member comprising lateral end portions of a base member with a non-planar profile to engage a similar profile of an adjacent roof cover element.
