Virginia Wind Planning for Standing Seam Projects

Wind design for a standing seam roof is an assembly decision—not a promise attached to a panel by itself. The required panel profile, gauge, clip, fastener pattern, edge details, underlayment, and substrate must be selected and approved for the specific building and location.

Important: MidAtlantic Metal Systems fabricates and supplies standing seam panels, trim, and related materials. We do not provide structural engineering, code approval, permit approval, or a project-specific wind design. The contractor, project designer or engineer, manufacturer, and authority having jurisdiction must determine and approve the complete roof assembly.

Start With the Project Requirements

Before ordering panels for a Virginia project, confirm the applicable code edition, project risk category, site exposure, roof geometry, substrate, and design pressures with the appropriate qualified professional and local building department. Regional wind maps can be useful for early planning, but they are not a substitute for a site-specific design.

Match the Entire Assembly

A standing seam roof performs as a system. Panel profile and steel gauge are only part of that system. Clip type and spacing, fasteners, substrate, underlayment, perimeter and corner details, penetrations, and installation methods all affect performance. Product test information applies only when the installed assembly matches the tested configuration.

• Use the approved construction documents and manufacturer instructions.
• Confirm the exact panel profile, gauge, clip, and fastener requirements before ordering.
• Do not substitute materials or spacing without approval from the responsible designer or manufacturer.
• Coordinate edge metal, trim, and flashing with the approved roof details.

What MidAtlantic Metal Systems Supplies

Our standard standing seam offerings are Englert 24ga and 26ga steel. We form 1-inch mechanical-lock panels in 17- and 21-inch finished widths and 1.5-inch snap-lock panels in 16- and 20-inch finished widths. Matching trim, flashing, clips, screws, butyl tape, rivets, closures, and flat sheets can be included in the material package.

Aluminum and other special-metal requests are reviewed and quoted case by case, subject to material, profile, tooling, lead-time, and warranty availability.

Information to Send With a Quote Request

Provide the approved panel profile, finished width, gauge, color, exact panel lengths and quantities, trim schedule, accessory requirements, project address, and requested fulfillment method. Upload plans, a cut list, panel schedule, or relevant approved roof details when available.

On-site roll forming may be available for qualifying projects, subject to panel length, approved measurements, jobsite access, setup space, project location, material availability, and scheduling.

Keep Responsibility Clear

MidAtlantic Metal Systems can fabricate the requested material package and coordinate pickup, delivery, or qualifying on-site roll forming. Final selection of the roof assembly, wind design, code compliance, permitting, and installation remains with the contractor and the project’s qualified design and approval team.
