Abstract

A ventilating device for a roof having at least one vent opening. The ventilating device includes a cover extending along the vent opening. The cover may include two plies of material, a top ply and a bottom ply that are spaced apart by connecting members extending between the plies. The ventilating device may also include coiled members extending longitudinally along the cover on opposite sides of the vent opening to support the cover over the vent opening. The coiled members may have spaced coils defining passages therebetween to permit venting of the structure through the vent opening and the passages defined by the coils. A portion of the bottom ply of material of the cover is removed, where the coiled members are attached to the cover. The ventilating device may further include at least one air-permeable filter member to inhibit moisture and debris from entering in the vent opening through the passages. Two adjacent longitudinal portions of the bottom ply of material may be removed for the attachment of each coil member. The spaced coils of the coil members may be threaded interstitially between the connecting members extending between the plies of the cover and held by the portion of the bottom ply remaining between the adjacent longitudinally removed portions of the bottom ply.
