Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.

Frequently asked questions

Why are walk pads needed on a roof membrane?
Walk pads protect the roof membrane from foot traffic wear, tool drops, and puncture damage along routes that maintenance and service personnel regularly use to reach rooftop equipment.
Does panel size vary by manufacturer?
Yes — always check the specific panel dimensions from your manufacturer. This calculator uses a common panel size of roughly 0.75m × 1.1m (about 0.84 m²) as the default, but actual coverage per panel depends on the product selected.
Does this account for panel overlap or cutting at edges?
No — this calculates the base full-panel count for the walk path area. Overlap between panels, cuts to fit around penetrations or path turns, and any adhesive/fastening accessories should be accounted for separately.
