Calculators / roof structure

One roof-structure core.
Multiple systems.

Calculate roof geometry and schedule materials for site-cut timber rafters, prefabricated trusses, engineered timber, light-gauge steel or an unusual manual layout. Numevaro does not design structural capacity.

The footprint is geometry only. Sections, spacing, grades, layout and connections must come from a verified technical source.

Material calculator

Roof structure

Select the structural system and input source first. Numevaro calculates quantities; it does not choose the structure.

1. Structure profile

2. Roof geometry

3. Site-cut rafters — inputs from technical source

For mono and gable roofs, ordinary rafter count is derived from the entered spacing. For hip roofs, Numevaro does not guess hip or jack rafter layout.

Rafter purchase / pricing

A catalog product is checked against the entered inputs and never changes section, spacing or structural length.

The cut plan is user-supplied: enter the final stock-piece count after saw kerf, trim allowances and reserve. Numevaro does not optimize cutting automatically.

Rafter product: manual inputs / no catalog product.

Additional structural members

Add members exactly as specified by the appropriate technical source. The same schedule can contain structural timber, engineered timber, light-gauge steel, prefabricated trusses and unusual members.

Member schedule

Numevaro does not check capacity, deflection, snow or wind loads, stability or connections. It does not size members and does not replace the structural input source.
