Estimating · Roofing

Roofing estimating: the field area, and everything around it.

We measure roof areas and every metre of flashing, upturn and parapet. You get quantities by system, or a priced bid ready to submit.

What you get

  • Quantities by element, in Excel and PDF
  • Or a priced estimate: labour, materials and equipment
  • Delivered before the BSDQ or contractor closing
  • A confidentiality agreement, if you want one

What we measure

What we take off your drawings.

Systems

SBS modified bitumen, TPO or EPDM, in m² per roof area and assembly.

Insulation

Flat and tapered insulation, cover boards and vapour barrier, layer by layer.

Perimeter

Parapet upturns, flashing, copings and expansion joints, in linear metres.

Details

Drains, overflows, penetrations, curbs and roof hatches, counted.

Two ways to work

Quantities only, or a priced estimate.

Quantity takeoff

Your quantities organized by element, the way you build your price. You apply your rates and submit.

Priced estimate

We add labour, materials and equipment, at Quebec market prices or your own rates. Ready to submit.

Watch out for

What we often see missing from a bid.

  • Parapet upturns taller than expected, adding membrane area.
  • Tapered insulation priced at an average thickness instead of the real slope plan.
  • Mechanical penetrations added late and never counted.

Frequently asked questions

What people often ask us.

Do you do residential roofs?

We mostly work on commercial, institutional and multi-residential projects, but we look at every request.

Can you compare two systems?

Yes. We can price an alternate, such as SBS versus TPO, on the same quantities.

Do you price re-roofing?

Yes, from the survey and specs: tear-off, deck repairs and the new system.

Send us your plans. We’ll get back to you within 48 hours.

Free and with no obligation. We confirm the scope, the fee for our service and the delivery date.
