Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Soffit area = eave length × soffit depth. Panels = round up (area × allowance factor ÷ panel coverage area).
FAQ
Soffit Material Calculator questions
Should every soffit panel be vented?+
Not necessarily. Vent layout depends on the roof ventilation strategy and product net-free area.
Why use coverage width instead of nominal width?+
Interlocking profiles may cover less than their nominal panel dimension.
Does this include channels and trim?+
No. J-channel, fascia trim, fasteners and corner details should be estimated separately.
