Green Metal Flashing Options for Your Roofing Needs

For masonry joint protection specifically, WEATHERCAP offers Type A (Flat Cap) for same-plane joints such as copings and cornices, and Type B (90° Cove Cap) for right-angle joints such as window frames and entrance steps. Both types are supplied in stock sizes (A-2 through A-8, B-2 through B-8) or custom configurations for non-standard joints.

WEATHERCAP joint caps are constructed from soft lead, chosen for its low elastic modulus and creep properties that allow permanent flexing without moisture penetration. Because lead is regulated under OSHA 29 CFR 1910.1025, installers should wear gloves and wash hands and body thoroughly after handling the material.

Yes. WEATHERCAP caps can be painted for aesthetic customization, and the lead surface also oxidizes naturally to a neutral grey over time that blends with most masonry and stone finishes, making it suitable for both new construction and historic restoration where appearance matters.

Cap selection depends on your joint width and configuration. Stock sizes range from A-2 (under 3/8 in) to A-8 (under 1 1/2 in) for flat joints, and B-2 (under 5/16 in) to B-8 (under 1 1/4 in) for right-angle joints. Weathercap provides sizing guidance, CAD drawings, and sample specifications to confirm the correct fit for your project.

Materials are typically shipped in 6-foot lengths within 48 hours of order placement. Because these are cut-to-length manufactured items, all sales are final and returns of material are not accepted, so accurate sizing before ordering is recommended.

Yes. WEATHERCAP is specified in the US General Services Administration's Historic Preservation Technical Procedures and has been used on landmark restorations including the Washington Monument, US Supreme Court, and multiple state capitols, making it a trusted choice for preservation-sensitive masonry joint repair.
