A roofer’s order of work
The workflow follows the order the job actually runs in—plan, scale, measure, production pieces, material order—instead of a generic measuring sequence.
Metal roofing takeoff
Metal roofing takeoff software, built for Australian metal roofing
RoofDatum is metal roofing takeoff and estimating software for desktop, designed and built by an Australian metal roofer. Import PDF plans, confirm the scale, measure metal-roofing components and turn the takeoff into production pieces and material documents.
Product scope
Built for metal roofing
RoofDatum is designed around metal-roofing takeoff and production workflows. Measure roof sheets, gutter, fascia, ridge, valley, barge, apron and other metal-roofing components from PDF plans, then apply configurable production rules to prepare material and supplier documents.
From version 6.7.0 a project can also be created as a Tile Roofing project. Roof tile projects have their own tile, capping and batten calculations.
Measurement system
Metric only
RoofDatum currently uses metric measurements throughout its takeoff and production workflows. Imperial units are not supported.
Who builds it
Built by an Australian metal roofer, for Australian metal roofing
RoofDatum is not a general measuring tool with a roofing menu bolted on. It is designed and built by a working Australian metal roofer, around the way metal roofing is actually measured, ordered and installed here.
Australian metal roofing
Metric throughout, and built around the components, allowances and material conventions used on Australian metal roofs.
Shaped by real jobs
Allowances, maximum lengths, splits and product settings are there because jobs on site need them, not because a feature list asked for them.
RoofDatum is published by ROOFDATUM PTY LTD.
What RoofDatum does
From the plan set to the material order
Everything you need for a clearer, more efficient metal-roofing takeoff—from importing plans to preparing supplier documents.
PDF plan workspace
Import complete PDF plan sets and keep every page organised within the project. More on working from PDF plans.
Double scale verification
Set the scale from one known dimension, then validate it against a second before the takeoff tools become available.
Precise measurement tools
Capture roof measurements with purpose-built tools that keep you in control.
Accurate roof areas
Apply pitch to roof areas so quantities reflect the slope—not just the flat plan footprint.
Production pieces, not just lengths
Measurements become sheets, flashings and production pieces you review before ordering, fabrication or cutting.
Supplier-ready documents
Turn your reviewed takeoff into organised quantities and professional supplier documents. More on the estimating side.
System compatibility

Professional-use reminder
RoofDatum is a user-operated takeoff and estimating aid. Results depend on the accuracy of the plan, reference dimensions, geometry, pitch, product settings and information entered by the user. Measurements and quantities should be independently reviewed before quoting, ordering, fabrication or construction.
RoofDatum does not guarantee accuracy, does not verify plans, does not perform engineering, and does not check code compliance.
