Introduction
Roof leakage usually starts before installation: in the slope logic, drainage capacity, flashing interfaces, and uncoordinated penetrations. This checklist helps project teams review those risks before material ordering and site execution.
For more context on this solution, review Standing Seam & ZIP Roofing as the related system.
For an executed example of this approach, see Mehrabad Airport Aircraft Hangar in the project library.
When to Use This Guide
Before approving shop drawings for industrial roofs.
When a roof has long spans, multiple penetrations, gutters, or mixed systems.
Before repair work on an existing roof leakage problem.
Technical Context
Technical guides cover sandwich panel selection, core types, thickness, thermal insulation values, joint logic, standing seam and ZIP roof drainage, and system comparison to support informed decisions before procurement.
- Sandwich panel and roofing system selection criteria
- Thermal insulation and joint coordination
- Procurement review before ordering
Key Technical Points
A structured overview of the key sections covered in this resource.
Drainage path
Confirm slope, gutter capacity, overflow strategy, and low-point behavior before panels are installed.
Penetration control
Review every skylight, duct, pipe, and equipment base as a waterproofing detail, not only an opening.
Flashing sequence
Check that flashings, closures, sealants, and panel laps follow a buildable installation order.
Common Mistakes
Checking panels but not transitions
Most leakage risk appears at edges, penetrations, gutters, and roof-to-wall interfaces.
Leaving drainage review until site work
Once purlins and gutters are fixed, correcting drainage errors becomes expensive.
