Our Vent Pipe Caps are designed to fit over metal pipes extending through the roof.
Vent pipe caps are an easy solution to replacing a damaged or weathered vent without the need to modify an existing vent pipe installation. Active Ventilation Product Vent Pipe Caps and Pop Vent Caps allow you to simply remove the vent head from a standard vent pipe and install the matching size vent cap.
The vent cap all aluminum construction is durable, lightweight, and will never rust! Our vent caps are not open to the sky, so they keep out rain, snow and debris. These static vent pipe caps have vertical louvers that allow air to pass through while preventing insects, birds and animals from entering the pipe. Diameter sizes 3 in. through 10 in. feature our Round Back design, while diameter sizes 12 in. to 24 in. feature our Pop Vent design.
If after examining the vent pipe and find that the attachment to the roof is not leaking, note the diameter of the pips at the top. This is the size vent pipe cap you require to retrofit a solution. If the vent pipe connection to the roof is damaged, is loose, or leaking in any way, then you may require a vent that includes a flange (to connect to the roof deck or under the shingles) and a “collar”, which is the vent pipe between the flange and the vent cap or “head”. Please see our Round Back Vents, Aura Vents, Breather Vents, and Keepa vents.
