We offer copper, stainless steel and galvanized chimney caps in large variety of standard and custom sizes. Copper and stainless steel chimney caps come with a lifetime manufacturer’s warranty. Custom lids or bonnets are available in 3 styles: flat, hip, hip& ridge. Most of our single flue chimney caps can be secured directly to the flue liner. If the flue liner does not extend high enough, we can use stainless steel top mounting brackets securing to the mortar crown. Our standard multi-flue chimney caps are designed with a swing-tab mounting strip for securing to the mortar crown. All the chimney caps come with ¾” screen mesh which acts as a spark arrestor and to prevent critters from getting into your chimney system.
