Metal & standing seam roofing
A clean metal roofline depends on careful work at the seams, edges and penetrations.

01 / Considerations
Standing seams and other profiles
Standing seam roofs use raised seams between panels, with attachment and seam design varying by system. Other metal profiles use different fastening arrangements. Roof pitch and panel length influence the choice. A new installation should follow the selected system's requirements rather than treating all metal roofing as the same product.
02 / Considerations
Allow for movement and exposure
Metal expands and contracts with temperature changes. Clips, fasteners and details need to accommodate the intended movement. Coastal exposure also makes metal selection, coatings and compatibility important. Pair the roof with suitable flashing and avoid assuming any exposed metal combination will perform equally well near salt air.
03 / Considerations
Build the roof below the panels
Substrate flatness, underlayment and condensation control affect the finished assembly. Penetrations must be detailed to work with the panels, and runoff needs a considered drainage route. When comparing replacement choices, include the complete assembly, access and maintenance needs.
