Our calculator uses current 2026 market rates and accounts for roof pitch, complexity, square footage, and project-specific factors. Most estimates come within 10–20% of the final quote. Actual pricing depends on exact measurements, site accessibility, deck condition, and material selection. We always provide a free on-site assessment to confirm the final price.

Asphalt shingles are the most affordable option with a lifespan of 20–30 years. Metal roofing costs more upfront ($11–16/sq ft vs $4.80–6.50/sq ft) but lasts 40–70 years, provides superior energy efficiency, handles extreme Canadian weather better, and requires minimal maintenance. Over the lifetime of the roof, metal often proves the more economical choice.

In most cases, we recommend a full tear-off because it allows us to inspect and repair the decking beneath. Most Canadian building codes also limit the number of shingle layers. Installing over old shingles (a "layover") is cheaper but can void manufacturer warranties and hide existing problems. We'll assess this during the free on-site inspection.

A typical residential roof replacement takes 1–3 days for a straightforward asphalt job. Metal roofs or complex shapes may take 3–7 days. The total project timeline from initial contact to completion is usually 4–8 weeks (including quote, permit, material ordering, and scheduling). Emergency and expedited options are available.

All projects include a comprehensive workmanship warranty plus the manufacturer's material warranty. Asphalt shingles typically carry 25–50 year warranties. Metal roofing warranties extend 40–50 years. Our workmanship warranty covers any installation-related defects. Contact us for specific warranty terms.

Several factors can push costs toward the higher end: steep or complex roof pitch, damaged decking, multiple storeys, skylights or chimneys requiring custom flashing, permit requirements in your municipality, difficult site access, and premium material upgrades. Our calculator accounts for the most common variables; the free on-site assessment identifies any additional site-specific factors.

Not necessarily, but it's highly recommended and cost-effective. During a roof replacement, gutters are temporarily removed anyway. Combining both projects saves on labor costs, ensures proper integration, and protects your new roof from water damage. Gutter guards are especially worth adding at this stage since installation is more efficient.
