Calculateur de Rémunération à la Tâche pour Toiture

Calculez le coût de main-d'œuvre et de matériel par carré de toiture, à partir de la surface de toit, du taux à la tâche, de la capacité de l'équipe et du facteur de perte.

sq ft
$/square

Labor pay per 100 sq ft (one "square") of actual roof area.

squares/day
$/square

Shingles/underlayment/fasteners per square. Leave at 0 for labor-only.

Piece-rate labor is paid on actual roof squares; the waste factor applies to material only, since crews aren't paid extra for material that ends up as offcuts.

Fonctionnement

How to use it: enter the roof's actual area (not including waste), your piece-rate pay per square (100 sq ft), the crew's realistic daily output, and material cost per square if you want a full job total rather than labor alone.

Calculation. Squares = roof area ÷ 100. Labor cost = squares × piece rate. Material cost = squares × (1 + waste %) × material cost per square - waste applies here because you buy extra material to cover cuts and overlaps, but piece-rate labor is paid on the roof's actual covered area, not the material purchased.

Avant d’utiliser le résultat

  • Measure from the datum or reference edge described by this tool, and do not mix inside, outside and centerline dimensions.
  • Keep inputs in the displayed units and preserve more precision than the final cutting or purchasing tolerance requires.
  • When the result is close to a limit, verify it with a test piece, field measurement, manufacturer drawing or qualified project professional.

Limites

This does not account for steep-roof or complexity premiums (many piece-rate agreements pay more per square above a certain pitch, or for cut-up roofs with lots of valleys/hips), tear-off of existing roofing, or disposal costs - add those as a separate line item.

Questions fréquentes

Should I use the roof's plan area or its actual (sloped) area?

Use the actual sloped roof area - multiply the building's plan (footprint) area by the roof pitch multiplier first if you're starting from a plan measurement, since piece rate and material are both based on the material actually covering the slope.
