Panel-Level Calculations for Every Facet on the Roof

Panel Takeoff tiles standing seam panels across your entire roof plan and gives you the numbers that matter: panel counts, individual lengths, linear footage, cut angles, and total metal squares. Every measurement is adjusted for the actual roof pitch, not the flat-plane footprint.

Set Your Panel Width. The App Does the Rest.

Once your roof geometry is in the app (imported or drawn), the panel calculator tiles panels across every facet automatically. You set the panel width to match the profile you're running. The default is 21-1/8", but you can adjust it with a slider or type in a custom value for any standing seam profile.

The calculator uses the rafter factor for each facet's pitch to convert flat measurements into actual panel lengths. A 10-foot run on a 6/12 pitch isn't 10 feet of panel. It's 11 feet 2 inches. Panel Takeoff handles that math on every facet, for every panel, automatically.

Per-Facet Breakdown

Panel count
How many panels cover the facet at your configured width.
Individual panel lengths
Not just an average. Every panel’s actual length, accounting for where it falls on the facet and how the geometry cuts it at the ridge, hip, or valley.
Linear footage
Total panel linear footage for the facet.
Cut angles
Where panels meet a ridge, hip, or valley, the calculator determines the cut angle. Your crew or roll former operator knows exactly how to cut each panel before they’re on the roof.
Metal squares
Total area for the facet in roofing squares.
Coil linear footage
Total linear feet of coil stock needed for the facet. If you buy coil and run your own roll former, this is the number you need for ordering raw material.

All of these roll up into project-wide totals so you can see the full picture alongside the facet-level detail.

Dial It In for Your Setup

Panel width
Adjustable from the slider or by direct input. Change it and every calculation on every facet updates instantly.
Waste factor
Set a per-panel waste allowance in inches. This gets added to each panel length so your material order accounts for the cuts and trimming that happen on every job.
Hip/ridge trim toggle
Include or exclude hip and ridge trim from the calculations depending on how you’re pricing the job.

Change any setting and the numbers update in real time. No recalculate button, no waiting. Slide the panel width from 16" to 18" and watch every facet's panel count and footage adjust immediately.

A Cut List Your Crew Can Actually Use

Panel Takeoff generates a per-facet cut list showing every individual panel length. Export it in the PDF cut report and hand it to your crew or your roll former operator.

No more measuring each panel on the roof and cutting one at a time. The lengths are calculated, the angles are set, and the list is ready before your crew shows up.

Why Per-Panel Calculations Beat Square-Footage Estimates

Most roofing estimating software gives you square footage and calls it a day. That works fine for shingles. It doesn't work for standing seam.

Standing seam panels are individual pieces with specific lengths that vary across every facet. A hip roof doesn't have uniform panels. Each one is a different length depending on where it sits. If you're ordering material based on square footage and a rough panel count, you're either over-ordering and eating the waste or under-ordering and waiting on a second delivery.

Panel Takeoff calculates every panel individually. You know exactly how many panels you need, exactly how long each one is, and exactly where the cuts fall. That precision means tighter material orders, less waste, and fewer surprises on install day.
