Build roof faces
Identify the visible roof planes and turn them into measured areas inside the takeoff.
Roof Scan Assist
Scan a roof plan instead of tracing every line.
Roof Scan Assist reads a calibrated roof plan, identifies the roof faces and supported roof lines, and builds the takeoff for you. On a clear, correctly calibrated plan, a typical simple-to-medium complexity roof commonly completes both scan stages in around 1-2 minutes, and simple roofs can be faster.

Direct answer
What does Roof Scan Assist actually do?
It automates the repetitive part of a roof takeoff from plans. Instead of clicking around the drawing to trace every face and roof line, you calibrate the plan, choose the appropriate scan option and let the system build the geometry for you.
Find supported roof lines
Detect supported ridges, hips, valleys, barges and spouting where the source drawing is clear enough.
Leave everything editable
Review the result, fix a line in seconds, add what is missing or switch to manual takeoff without changing tools.
Save attention, not only minutes
A fast scan is useful even when you are already good at manual takeoff.
A competent estimator might trace a straightforward roof in a few minutes. The difference is that manual tracing occupies those minutes. Roof Scan Assist can do the repetitive work while you use that attention somewhere else.

Fix only what needs it
Correct the small exception if there is one, then continue to the next step.
Two scan stages
Scan the outline first. Review it. Then choose what happens next.
Roof Scan Assist works in two phases, so the repetitive geometry work happens in a sensible order instead of one opaque pass.
The outside roof outline
The first scan traces the external roof outline, including the eave or gutter and barge or rake boundaries. You review that outline before continuing.
Internal roof components, optional
Draw the internal roof components manually, or ask Roof Scan Assist to detect them in a second scan. Both paths keep the result in the same editable workspace.
Choose the processing level for each stage.
Simple, Medium or Medium+ can be selected independently at each stage. Use lighter processing on an easy outside outline and heavier processing on more complicated internal geometry, so scan tokens are spent where they matter.
Lighter analysis
Suits straightforward geometry. Generally processes faster and uses fewer scan tokens.
Balanced analysis
A middle option for average roof complexity where more interpretation is useful.
Heavier analysis
For geometry with more to interpret. Can take longer and consumes more scan tokens.
The useful result is not an AI answer. It is editable roof geometry.
A scan does not lock you into what the model decided. Every area and supported roof line remains part of the normal Digital Takeoff workspace.
- Accept a complete result when it is right
- Fix one or two lines when the scan is close
- Add missing areas or components manually
- Discard the result and measure manually if the source plan is a poor fit
One connected workflow
The scan can be the first automated step, not the last.
Once the roof geometry is reviewed, the same job can continue into offcut planning, your own pricing logic and the customer quote without re-entering the measurements.
- 01
Roof plan
Upload or open the drawing and calibrate it.

Roof takeoff on mobile
Start an AI roof-plan takeoff from your phone, not only from a desktop.
Digital Takeoff and Roof Scan Assist are available on mobile. Field and office staff get another way to work with a roof plan away from the main computer, without reducing the result to a read-only report. Roof Scan Assist scans roof plans and drawings from the phone; it is not a camera or satellite scan of the physical roof.
Open the plan on mobile
Work from the same roof-plan workflow on a phone when that is the device in front of you.
Run Roof Scan Assist
Start the automated geometry scan on mobile, then come back to the measured result instead of tracing every line on a small screen.
Keep the result usable
The detected roof is still editable takeoff geometry that continues into the rest of the QuoteCore+ workflow.
Skill barrier
Lower the skill barrier for takeoff groundwork.
Roof Scan Assist does not replace roofing judgement. It can reduce how much specialist knowledge is needed to produce the first usable takeoff, which makes office delegation and staff training more practical.
Remove repetitive tracing
Use the scan to remove repetitive tracing and spend your attention checking unusual geometry or pricing the job.
Prepare the measured roof
Calibrate the plan, run the scan and prepare the measured roof for review without knowing how to draw every hip and valley manually.
Learn from the result
Use the editable result to learn what the roof geometry should look like while an experienced person reviews the commercial work.
Accuracy
Three things determine how much manual correction a roof scan is likely to need.
The scan is strongest when the input gives it unambiguous information. These are the three factors worth checking before you decide whether the job suits automation.
Correct calibration
Set the plan scale from a reliable known dimension. A good geometry result with the wrong scale still produces the wrong real-world measurements.
Clear source drawing
Sharp, readable roof lines are easier to interpret than blurred scans, compressed images or overlapping construction markup.
Roof complexity
Simple and moderately complex roofs are more predictable. Unusual intersections are more likely to need manual judgement.
Good fit, clear limits
Use AI where it removes work, and manual takeoff where it does not.
QuoteCore+ is built around a connected measure-to-price workflow. It is deliberately not trying to replace every piece of software in a construction business.
Best fit when
- Roof plans with a reliable known dimension for calibration
- Simple to moderately complex geometry that would otherwise be traced manually
- Teams that want to delegate more of the takeoff groundwork
- Roofers who want an editable result rather than a static report
- Mobile users who want to avoid detailed manual tracing on a small screen
Know before you choose it
- Poor-quality or ambiguous drawings can need more correction
- Incorrect calibration produces incorrect real-world measurements
- Highly unusual roof geometry may still be faster to finish manually
- The result should be reviewed before it is used for pricing or ordering

AI roof takeoff and Roof Scan Assist FAQ
Practical answers about how QuoteCore+ fits into real estimating, takeoff and quoting workflows.
What is an AI roof takeoff?
Software interprets a roof plan and builds measured roof geometry automatically. QuoteCore+ leaves that geometry editable for review rather than returning a static report.
Can I use Roof Scan Assist on my phone?
Yes. Roof Scan Assist is available in the mobile Digital Takeoff experience as well as on desktop. It scans roof plans and drawings from the phone; it is not a camera or satellite scan of the physical roof.
Can I scan an actual roof with my phone camera?
No. Roof Scan Assist is designed for roof plans and drawings. It is not a satellite report or camera-based physical roof scanner.
How accurate is it?
There is no single percentage for every drawing. Correct calibration, source-plan clarity and roof complexity are the main variables that determine how much review or correction the result needs.
Why use it if I can trace manually?
It can reduce hands-on attention even when manual tracing is already fast. On a clear, correctly calibrated plan, a typical simple-to-medium complexity roof commonly completes both scan stages in around 1-2 minutes, and simple roofs can be faster. You can use that short window for another task, then review and fix only what needs correction.
Does a complex scan use more tokens?
Yes. Each of the two scan stages can use the level that suits that part of the roof. For example, use Simple for an easy outside outline and Medium+ for more complicated internal geometry. Heavier processing can take longer and use more scan tokens, so you do not need to spend maximum tokens on every stage.
Why are there two scan stages?
The first scan traces the outside roof outline, including the eave or gutter and barge or rake boundaries. You review that outline first. Then you either draw the internal roof components manually or run the second scan to find them. You can choose Simple, Medium or Medium+ independently for each stage.
Can I edit the result?
Yes. Correct, add, continue manually or discard the automated result in the same workspace. The normal Digital Takeoff tools remain available at every stage.
