The free calculator is built for the quick question that comes up before ordering material: how much ice and water shield do we need at the eaves and valleys?
See The Calculator And Output
Use the calculator for the membrane quantity, then keep the PDF as a clean record of the assumptions, roll count, and coverage view.
How The Free Calculator Works
The workflow is intentionally simple, but the assumptions stay visible so you can adjust the calculation to the job.
Use manual mode for quick totals, or upload a supported roof file when you want shaded coverage on the roof sketch.
Review pitch, overhang, wall thickness, interior coverage, valley width, waste, and roll coverage. State guidance is editable.
Check required depth, net square footage, waste, roll count, and whether CAD membrane overlaps were removed before waste.
Use the PDF for your file, your estimator, or a conversation with the crew before ordering material.
Try The Free Calculator, Then Discover The Full Takeoff Workflow
Ice and water shield is a focused free tool inside Panel Takeoff. If you also need roof measurements, material quantities, order information, and report PDFs, Instant Report builds on the same estimating mindset.
State guidance is advisory and editable. Always confirm the local requirement for the job you are estimating.
