How we measure roofs

See a Roofing Takeoff in 3D

Each roof plane is measured on the slope at its true pitch, then ridges, hips, valleys, barges, gutters and downpipes — so the quantities match the roof that will be built.

  1. The roof plan is read with the elevations and sections, and the pitch is taken from the drawings — 25° on this model.
  2. Every plane is modelled at its true pitch, so nothing is measured flat on plan.
  3. Each plane is measured on the slope and totalled, then sarking is allowed with laps.
  4. Ridges, hips, valleys and barges are measured at true length for cappings and flashings.
  5. Eaves gutters are measured in lineal metres and downpipes counted.
  6. Quantities set out by item and unit, with a marked-up roof plan — ready for your rates.

Scope

What’s Included

The scope is confirmed with you before work starts, so you know exactly what will be measured and priced.

  1. Roof areas

    Each plane measured on the slope, so areas in m² are pitch-adjusted rather than plan areas.

  2. Coverings

    Sheets by profile and length, tiles from the coverage rate per m², or membrane in m² with laps, plus fixings where specified.

  3. Flashings & trims

    Ridges, hips, valleys, barges, apron and wall flashings in lineal metres, with hips and valleys at true length.

  4. Insulation

    Insulation, sarking and underlay in m², allowing for laps.

  5. Roof drainage

    Gutters and downpipes in lineal metres; sumps, outlets and rainheads counted.

  6. Pricing

    Labour and material pricing where requested.

FAQ

Common Questions

Yes. Each roof plane is measured on the slope using the pitch shown on the drawings, and hips and valleys are taken at their true length. Where the pitch is not shown, the assumed pitch is stated.

Yes. Gutters and downpipes are measured in lineal metres, and sumps, outlets and rainheads are counted and scheduled.

Yes, both. Send the drawings to confirm scope.

Yes. Wall cladding and its flashings and trims can be measured alongside the roof, with roof and wall quantities kept separate so each package can be priced on its own. See Cladding Estimating for what is included.
