Roofing estimating & takeoff services
Shingle, membrane, metal and built-up systems measured on the slope, with every layer of the assembly counted as its own line.
What a roofing package looks like.
A roof is an assembly, not a surface. Membrane, cover board, insulation, vapour barrier and underlayment each carry their own area, rate and wastage, and pricing them as one composite rate makes a specification change impossible to reprice.
Areas are measured on the slope rather than in plan, which on a 6:12 pitch is an 11% difference nobody can absorb. Perimeter items, penetrations, flashing and edge metal are counted individually because they carry most of the labour on a small roof.
Measured in
What we look for specifically
- Plan area used instead of slope area
- Tapered insulation averaged rather than measured by zone
- Penetrations and flashing rolled into a square-foot rate
- Tear-off and disposal missing on a re-roof

Who it is for
Roofing subcontractors, general contractors, building envelope consultants and re-roofing specialists.
Every roofing package ships the same four things.
Whatever the trade, the deliverable is consistent, so a package from us always drops into how you already work.
Excel workbook
Line-item detail with quantities, wastage, labour hours and material priced on separate columns.
Colour-marked sheets
Every measured item marked on the drawing with a count legend, so any figure can be checked against the plan.
Assumptions & exclusions
Written down, including anything the drawings did not answer, rather than absorbed into a rate.

Common questions on roofing takeoffs.
On the slope, using the pitch from the drawings. Plan area understates a pitched roof by the pitch factor, which is roughly 11% at 6:12 and over 20% at 12:12.
Yes, measured by area and number of existing layers where the drawings or survey state them, with disposal priced separately. If the existing build-up is unknown it is flagged as an assumption rather than guessed at.
By zone rather than by average thickness, so the board quantities and the crickets match what will actually be ordered.
Packages that usually travel with this one.
Most enquiries cover more than one division. Bundling them into a single engagement keeps the assumptions consistent across the whole bid.
