Roofing estimating services for Canadian contractors

A roof estimate starts with a measurement that is harder than it looks: the true sloped area, which is bigger than the area you see on the plan. Add valleys, hips, flashings, penetrations and tear-off, and the numbers drift quickly.

We prepare roofing and siding takeoffs from your plans, in squares and square feet, with accessories and waste shown on their own lines.

| What we count and price

Sloped roof area, using the pitch, in squares (100 sq ft each)
Shingles, underlayment and ice-and-water membrane at eaves and valleys
Low-slope systems: modified bitumen (SBS), TPO, EPDM, tapered insulation
Metal roofing, flashings, drip edge, vents and penetrations
Roof drains, scuppers and curbs
Siding, soffit, fascia and eavestroughs

| Canadian roofing detail

Ice-and-water protection at eaves, valleys and penetrations
Snow load and drift considerations on the structure
Winter roofing limits: adhesives, torch and membrane work have temperature limits
Typical Canadian low-slope roofs: 2-ply SBS and tapered insulation systems

| Waste factor

Roofing waste is normally 5 to 10% of material, shown as its own line. Simple gable roofs sit at the low end, and cut-up roofs with many hips and valleys sit at the high end.

| Measured from your plans

We measure from the drawings you send. If the plans do not show enough detail, we ask for what is missing before pricing.

| Timing

Small roofing takeoffs are normally ready in about 4 to 6 hours and larger projects in 6 to 48 hours, depending on size and urgency.
