Ballpark Estimator

Get a ballpark before anybody knocks on your door.

Roofing is measured in squares — one square is 100 square feet of roof. Give us your footprint and your pitch and we will do the math the same way we do it on paper.

Put in your length and width below and the number fills in.

1. Your footprint

The outside measurements of the house on the ground — not up the slope. The pitch below handles the slope.

Length (ft)Width (ft)

2. Roof pitch

How steep it is. A steeper roof has more surface than the ground it covers, and takes longer to walk.

The most common house roof around here.

3. Material

What goes back on top.

4. Layers to tear off

Not sure? Look at the edge of the roof from a ladder — you can usually count the layers there. Most houses have one.

This is a ballpark, not a quote.

It cannot see your decking, your flashing, your chimney, or how the roof is cut up with valleys and dormers — and those are exactly the things that move the price. Nobody should give you a binding roof number off a website. Jerry will walk it and put a real one in writing, free.

Not sure about your numbers?

Footprint and pitch are the two people guess at, and a bad guess on either one throws the whole thing off. Here is how to get them right — or skip it and let us measure it for you, free.

How to measure your roof footprint

Walk the outside of the house and measure length by width. You want the area the house covers on the ground, not the slope of the roof — the pitch multiplier handles the rest.

How to read your roof pitch

Pitch is rise over run — how many inches the roof climbs for every 12 inches across. From the ground you can usually eyeball it against a neighbor, or hold a level against a rafter in the attic.

How the math works

What is a roofing square?

One hundred square feet of roof surface. Roofers price and order in squares because that is how shingles come — three bundles to a square, more or less. A 2,000 square foot roof is 20 squares.

Why does pitch change the price?

A steep roof covers more surface than the ground underneath it, so there is more material. It is also slower and more dangerous to walk, so there is more labour. Both go into the number.

Why is there a waste factor?

Shingles get cut at valleys, hips, rakes, and around penetrations, and those offcuts are paid for. Twelve percent is a normal allowance on a typical roof — a complicated roof with a lot of valleys runs higher.

Why is this a range instead of a price?

Because a website cannot see your decking, count your layers for sure, look at your flashing, or know whether the truck can get close to the house. Those are the things that move a roof price, and the only way to settle them is for somebody to get up there. That visit is free.

Now get the real number.

This is a ballpark, not a quote. It cannot see your decking, your flashing, how many layers are up there, or whether the pitch changes halfway across. The real number comes from Jerry walking the roof — and that visit is free.
