Metal Flashing Roll: Durable Solutions for Roofing Projects

The primary purpose of metal flashing is to prevent water from penetrating a structure at joints or angles. It directs water away from vulnerable areas. WEATHERCAP® enhances this by using soft lead that creeps into new joint configurations as buildings move, maintaining a continuous, flexible seal that protects the underlying sealant from failure.

Standard flashing is typically a rigid material like aluminum or steel used for roofing. WEATHERCAP® is a patented, soft lead cap system designed for masonry joints. Its flexibility allows it to absorb stress and move with the building, preventing sealant failure—a problem rigid flashing cannot solve in masonry applications.

Our system is ideal for protecting horizontal and vertical masonry joints. Common applications include copings, parapets, cornices, belt courses, window and door lintels, and water tables. It is extensively used in historic building preservation, restoration projects, and high-quality new construction to ensure long-term weatherproofing.

Yes, absolutely. While renowned for historic restoration, WEATHERCAP® is an excellent choice for new construction to prevent future joint failure. By incorporating our system into new masonry, architects and builders can ensure superior, long-lasting protection against moisture penetration from the outset, reducing long-term maintenance costs.

WEATHERCAP® is designed for straightforward installation by qualified masonry contractors. The soft lead caps are installed as an adjunct to caulk or sealant in prepared joints. We provide comprehensive technical information, sample specifications, and CAD drawings to support architects and installers, ensuring proper application for optimal performance.

We offer two main configurations: Type A (Flat Cap) for same-plane joints and Type B (90° Cove Cap) for right-angle joints. Both types are available in a range of stock sizes to accommodate various joint widths, from under 3/8 inch to 1 1/2 inches. Custom sizes can also be manufactured for unique project requirements.
