Outside mount chimney caps come with a “skirt” which is placed over the top of the chimney to fit like the lid of a shoebox. To clarify, the skirt protects the corners of the chimney and the kicker edge helps deflect water away from the sides of the chimney. Like an “umbrella”, the lid is larger around than the chimney, to protect it from water.
The screen sides are at least 10″ high ( due to code) to provide sufficient venting space or they can be made higher if requested, to accommodate tall flue tiles, top seal dampers, or other variables on the top of the chimney.
Caps are attached with stainless steel “tapcon” connectors (screw-like). Which are driven through the sides of the skirt and into the masonry (so there are no holes in the flat part of the skirt which could possibly allow water)
Lids can be “flat” or “hip and ridge”, which has a sharper angle (like the roof of a house), and decorative seams (or “ridges”) along with the angles (or “hips”) of the roof. The beautiful, high-end “hip and ridge” diverts water more than the flat lid would.
