- 3. You get a written quote. Your quote lists the material, tear-off, underlayment, flashing, ventilation and clean-up so you know exactly what is included.
- 4. We schedule the work. Once you approve, we book your roof replacement and keep your property clean and safe from start to finish.

Roof estimate FAQ
Is the roof estimate really free?
Yes. The online estimate and the on-site inspection are free and come with no obligation. You only pay if you decide to go ahead with the work.
How accurate is the online roof estimate?
The calculator gives you a quick estimate of your roof size based on your home footprint, number of storeys, pitch and shape. Before we give you a final price, we measure the roof in person or with a drone inspection so your quote reflects the real roof.
What affects the cost of a roof replacement?
The main factors are roof size, pitch and complexity, the material you choose (asphalt shingles, architectural shingles or metal), how many old layers need to be removed, and extras such as skylights, chimneys, flashing, ventilation and eavestroughs.
