Chimney Caps & Chase Covers

Chimneys must be protected against intrusion from the elements, as well as birds and animals. The NFPA requires a spark arrest for operational chimneys. A good quality chimney cap is your best protection and cheapest investment against water penetration, animal intrusion, and provides spark arrest. Birds, bats, raccoons, opossum, rats and yes even cats can be costly to remove from a chimney system.

Chimney Swifts are a common breed of birds which nest inside chimneys and cannot be removed as they are protected by Federal Law under the Migratory Bird Treaty Act. Anyone who knowingly destroys birds or nests that might contain eggs or young can be fined up to $15,000.

Animal intrusion can block a flue, rendering the heating appliance or hot water heater useless and cause carbon monoxide poisoning inside the home.

Many homes have chimneys that are built incorrectly with inadequate concrete covers or masonry slab covers. Chimneys with masonry or concrete slabs typically do not have adequate spark arrest and do not prevent water or animals from entering the chimney. Too often this result in rust damage to metal firplace components such as throat dampers, and metal fireboxe. Water damage can cause gas logs to fail prematurely. Concrete slab covers and masonry slab covers are not adequate protection and should be removed and replace with a good quality corrosion resistant metal chimney cap.

A good quality chimney cap will cover your chimney flue, provide spark arrest, prevent animal intrusion, and provide water shed away from the crown. We prefer Hy-C brand chimney caps with a band around or skirt mounting system with a top that extends one inch on all sides around the chimney crown. In our experience this is the best system to prevent moisture problems.  Stainless steel is the material of choice however we find aluminum to be a cost effective substitute that is durable and effect. Galvanized is the cheapest, however we seem to replace them on a regular basis as they rust quickly and often stain the chimney and roof. Additional materials are available including patina copper, bright copper, painted galvanized, stainless steel, and aluminum.
