Capability for Columbus commercial properties
A roof zone diagram is the spatial foundation of every other roofing document — condition reports, moisture survey maps, warranty compliance records, and capital plans. Without it, every inspection produces a description with no location. We produce scaled roof zone diagrams that make every subsequent document about that building usable.
A commercial roof without a zone diagram is a building that cannot be systematically managed. Every inspection produces a list of findings with no spatial reference — 'flashing separation near north HVAC unit' is not actionable unless you know which of the three HVAC units on the north side of the roof, how far from the parapet, and what the surrounding membrane condition looks like. Roof zone mapping solves this problem by establishing a permanent spatial reference system for the building's roof assembly.

Owner-side support is centered on defensible roof information: photos, measurements, moisture findings, repair history, bid assumptions, and budget timing.
The output is written so owners can compare options, defend budgets, manage procurement, and keep roof information useful after the immediate decision is made.
Questions
Standard deliverable is a scaled PDF suitable for field use and lender documentation. CAD format is available on request — either DXF or DWG — for buildings where the owner's engineering team or facilities management system requires a CAD base file. CAD deliverables add time to the engagement; confirm the format requirement at the start of the engagement.
Yes. If you have a zone diagram from a prior contractor — in any format we can read — we can use it as the starting point, verify and correct it during a field visit, and update the penetration inventory and zone boundaries to current conditions. Updating an existing diagram is faster than mapping from scratch and costs less. If the prior diagram is not reliable enough to build on, we will tell you before we start.
No — we produce the zone diagram as the first step of an inspection engagement on buildings that don't have one. For small buildings, the diagram is produced on-site during the inspection visit. For larger buildings, we may schedule a brief pre-inspection site visit to take field measurements before the full inspection. We will not deliver a condition report on a building without a zone diagram because the report would have no spatial reference.
Share the building address, roof history, current concern, timing, and access constraints. We will give you a practical next step for inspection, repair, maintenance, coating, or replacement planning.
