Optimized for Efficient Water Flow
Designed to channel water away from joints and intersections, reducing the risk of pooling, leaks, and water intrusion.
American-Made Precision
Available in galvanized, galvalume, aluminum, copper, and pre-painted finishes for broad system compatibility.
Multiple Material Choices
Available in galvanized, galvalume, aluminum, and copper to match system requirements, environmental exposure, and aesthetic preferences.
Compatible with All Major Roofing Types
ECM valleys work seamlessly with tile roofing systems, asphalt shingles, and metal roofs, making them a versatile choice for manufacturers and installers.
Built for Harsh Environments
High-strength materials resist corrosion, uplift, and heavy runoff, supporting performance in coastal, high-wind, and high-rainfall regions.
Profiles to Match Any System
Choose from multiple valley types; including preformed tile valleys, roll valley, W valley, and shingle valley to meet project specifications and roof geometry.
Valley Applications
ECM Valleys are ideal for:
- Tile roofing systems
- Asphalt shingle roofs
