Common use cases
Frequently asked questions
What does this template help inspectors verify?
It guides inspectors through the key checks for TPO single-ply seams, including overlap, weld quality, peel test results, and edge termination. This helps teams document defects consistently and identify areas that may need repair.
Can this be used for both new installs and maintenance inspections?
Yes. It works for post-install quality checks, routine maintenance inspections, and follow-up assessments after repairs or storm events. The structure makes it easy to compare results over time.
Does the template support field documentation?
Yes. It includes inspection details, measured values, and notes so crews can record conditions on site. That makes it easier to share findings with roofing contractors, facility teams, or project managers.
What kinds of seam defects can be captured?
The template covers common issues such as inconsistent seam width, poor heat weld fusion, fishmouths, voids, wrinkles, and edge separation. It also captures termination problems like loose bars or failed sealant.
Who would use this inspection form?
Roofing contractors, facility managers, and building inspectors can all use it to standardize seam evaluations. It is especially useful for teams responsible for commercial flat roof maintenance.
