Sheet Metal Chimney Caps for Durable Protection

The ideal material for a chimney cap balances durability, corrosion resistance, and cost. Stainless steel is a popular all-around choice, offering excellent longevity and strength. Copper is a more premium option, known for its beautiful appearance and exceptional lifespan. Galvanized steel provides a cost-effective solution, though it may not last as long as stainless steel or copper in harsh weather conditions.

The system works by covering the sealant in a masonry joint. The soft lead cap absorbs stress from building movement, reduces the joint opening size, and shields the sealant from UV radiation and weather. This prolongs sealant life, prevents margin checking, and ensures a long-lasting, weather-resistant seal that prevents moisture penetration and related damage.

Type A is a flat cap designed for joints where masonry units are in the same plane, such as the top of a coping or across a belt course. Type B is a 90-degree cove cap used for right-angle joints, such as where a projecting lintel meets a wall, at window sills, or around the perimeter of a glass block panel. The choice depends entirely on the geometry of the joint.

Absolutely. While renowned for historic preservation, WEATHERCAP® is highly effective for new construction, ensuring maximum durability from day one. The WEATHERCAP A-2 Type A cap is specifically designated for new construction installation only. Incorporating our system into new projects provides superior, long-term protection against joint failure due to movement and settlement.

Yes, with standard safety precautions. As a lead product, workers should always wear gloves and wash their hands and body thoroughly after handling the material. The product is regulated under OSHA 29 CFR 1910.1025, and following these guidelines ensures a safe installation process. Once installed, the material is stable and poses no risk.

Yes, the caps can be painted to match any desired color, allowing for seamless integration with the building's aesthetic. If left unpainted, the soft lead surface quickly oxidizes to a neutral grey color that naturally blends in with most stone and masonry, making it visually unobtrusive while providing continuous protection.
