What RoofDatum does
Purpose-built for metal roofing
Everything you need for a clearer, more efficient metal-roofing takeoff—from importing plans to preparing supplier documents.
Precise measurement tools
Capture roof measurements with purpose-built tools that keep you in control.
Double scale verification
Set the scale from one known dimension, then validate it against a second before the takeoff tools become available.
Accurate roof areas
Apply pitch to roof areas so quantities reflect the slope—not just the flat plan footprint.
Flexible production settings
Configure allowances, maximum lengths, splits and material settings for your workflow.
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.
Local project storage
Keep projects on your computer and work without relying on the cloud or an internet connection.
Portable project files
Package an entire project into one file for backup, transfer or use on another machine.
Measurement confidence
The scale is checked before the takeoff begins
An incorrect drawing scale can affect every measurement that follows.
RoofDatum treats the scale as something to confirm rather than assume. You set it from one known dimension, then validate it against a second, separate known dimension. The takeoff tools sit behind that check, so a job does not quietly proceed on a scale nobody tested.
- Scale set from one known dimension on the page
- Validated against a second, independent known dimension
- The variance between measured and expected shown before you continue
- Takeoff tools become available once the scale is confirmed
The check confirms that the two dimensions you selected are consistent with each other. It does not verify the complete plan, and it cannot detect an error in a part of the plan you did not check.
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.
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.
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.
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.
From plan to order
Everything you need. One streamlined workflow.
RoofDatum turns complex roof plans into clear measurements, material quantities and supplier-ready documents—all within one modern workspace.
-
Bring in your plans
Upload your PDF plan set and keep everything for the project together.
-
Set up with ease
Prepare each page for fast, reliable measuring—without complicated configuration.
-
Scale with confidence
Set the plan scale from a known dimension and start measuring accurately.
-
Verify before you measure
Check against a second dimension to identify scale differences early.
-
See the result clearly
Review the scale result before moving into the takeoff.
-
Capture every roof detail
Measure roof areas, gutter, fascia, ridge, hip, valley, barge, capping and more.
-
Review everything in one place
Check measurements and generated production pieces in a clear, organised workspace.
-
Turn takeoffs into orders
Generate material quantities and professional supplier documents without rebuilding the job in another system.
Beyond measuring
Measurements are the halfway point, not the finish
A PDF measuring tool hands you lengths and areas. The real work is what comes after—turning those numbers into sheets, flashings and quantities you can actually put in front of a supplier.
RoofDatum carries the takeoff through. Measured components become production pieces under your own allowances, maximum lengths and splitting rules, laid out for review before anything is ordered or cut.
- Roof sheets, gutter, fascia, ridge, hip, valley, barge, apron and capping
- Pitch applied to roof areas, so quantities follow the slope and not the flat plan
- Your own allowances, maximum lengths and splitting rules applied to each piece
- Sheet order, battens, insulation and fixings quantified alongside the pieces
- Reviewed pieces carried into material quantities and supplier documents
Production pieces and quantities should be independently reviewed before quoting, ordering, fabrication or construction.

Professional use
RoofDatum is a user-operated takeoff and estimating aid
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.
The scale check confirms consistency between the two dimensions you selected. It does not verify the complete plan, and it cannot detect an error in a part of the plan you did not check. Plans can carry errors or distortion introduced by scanning, printing, conversion or cropping.
RoofDatum does not guarantee accuracy, does not verify plans, does not perform engineering, and does not check code compliance. Verify the scale, units and key dimensions against the latest issued plans, and have quantities reviewed by a suitably qualified person.
