Ridge Cap Roll Forming Machines for Metal Roofing

WEATHERCAP® is installed over sealant in a masonry joint. It covers the sealant, protecting it from direct exposure to UV radiation, weather, and environmental stressors. This coverage significantly extends the life of the sealant and helps prevent 'margin checking,' where the sealant pulls away from the edge of the joint. The system reduces the effective opening size of the joint, enhancing durability.

The soft lead used in WEATHERCAP® has a low elastic modulus and low creep strength. This allows it to remain flexible and slowly 'creep' into new configurations as the building moves or settles over time. Unlike rigid materials, it doesn't retain a fixed shape, ensuring it maintains a continuous, weather-resistant seal without tearing or shearing under stress.

Yes, WEATHERCAP® is suitable for both historic restoration and new construction projects. While it is renowned for its use in preservation, it provides the same long-term joint protection benefits for new masonry. The A-2 Type A cap is specifically designated for new-construction installation, and other configurations can be selected based on the joint geometry in new builds.

The primary difference is the joint configuration they are designed for. Type A is a flat cap used for joints where masonry units are in the same plane, such as the top joints of copings or lintels. Type B is a 90-degree cove cap designed for right-angle joints, such as where a horizontal surface like a window sill meets a vertical wall.

WEATHERCAP® maintains a full manufacturing and supply chain capability to ensure rapid order fulfillment. Materials are typically shipped within 48 hours of an order being placed. All products are supplied in standard 6-foot lengths for field cutting and fitting, allowing projects to proceed without delay. For custom orders, lead times may vary, so it is best to inquire directly.

Absolutely. WEATHERCAP® is a premier choice for historic preservation and is specified in the U.S. General Services Administration (GSA) Historic Preservation Technical Procedures. Its ability to accommodate movement in older structures and its appearance—oxidizing to a neutral grey that blends with masonry—make it ideal for preserving the integrity and appearance of landmark buildings.
