Abstract: An improved ridge vent that includes a support, a cover, a housing, and a concealing structure provides ventilation for a building. The housing contains a biocidal source. Rainwater flows down the cover, into the housing, and over the biocidal source. The water treated with the biocidal source then flows out of the housing and down the roof, inhibiting the growth of mold, moss, bacteria, and fungus. The concealing structure hides the biocidal source from view.

Abstract: A gutter cover assembly and corresponding methods of use, where the assembly is generally adapted for mounting on the edge of a roof and over an adjacent gutter. The assembly includes a cover adapted to extend over the edge of a roof and an adjacent gutter. The cover includes a mounting portion adapted for mounting on the roof, and a guard portion adapted to extend over the gutter to prevent leaves and debris from entering the gutter. The assembly also includes a support disposed under the guard portion to support the guard portion over the gutter. The cover is slideably disposed relative to the support before the cover is fixedly mounted on the roof.
