Lead Flashing and Roof Products at Home Depot

WEATHERCAP® lead caps are designed to work with sealant to create a durable, weather-resistant seal in masonry joints. They cover the sealant, protecting it from environmental exposure and UV damage, which significantly extends its life. The soft lead also flexes to accommodate building movement, preventing joint checking and moisture penetration where traditional sealants might fail over time.

Yes, WEATHERCAP® is suitable for both historic restoration and new construction projects. Certain products, like the A-2 Type A cap, are specifically designated for new installations. The system provides long-term protection for masonry joints in new buildings, preventing future issues related to sealant failure and moisture intrusion, making it a proactive choice for durable construction.

Yes, we offer two main configurations. Type A is a flat cap for joints on the same plane, like copings. Type B is a 90-degree cove cap for right-angle joints, like where a window sill meets a wall. Both are available in various stock sizes for different joint widths, and custom profiles can be ordered to meet specific project requirements.

Absolutely. While WEATHERCAP® naturally oxidizes to a neutral grey that blends well with most masonry, it can be painted to match specific aesthetic requirements. This allows architects and builders to seamlessly integrate the joint protection system into their design vision without compromising on color schemes for the building's exterior.

The system is made from soft lead, which has a low elastic modulus. This means it remains flexible and will 'creep' or deform slightly to accommodate building settlement and thermal expansion without cracking. This unique property ensures the joint remains sealed and protected, preventing moisture intrusion even as the structure moves over time.

As with any lead product, proper handling is important. It is regulated in the U.S. under OSHA 29 CFR 1910.1025. We recommend that installers always wear gloves when handling the material and wash their hands and body thoroughly after installation is complete. Following these simple safety measures minimizes any potential risks associated with handling lead.
