What Affects the Cost of a Roof Replacement? Breaking Down the Budget

A new roof is one of the most important investments you can make in your home—but how much should you expect to spend? At CT Roofing Solutions, we understand that homeowners in Barrie and surrounding areas want a clear, honest breakdown of what goes into the cost of a roof replacement.

The truth is, roofing costs can vary significantly depending on several key factors. In this post, we’ll walk you through what affects the final price so you can plan your budget confidently and avoid surprises.

1. Roof Size and Square Footage

The larger your roof, the more materials and labor are required. Roofing is typically priced per "square," which equals 100 square feet of roof area. If your home has complex rooflines or multiple levels, the size calculation can increase quickly.

Tip: Ask for a detailed estimate that breaks down cost per square so you can compare fairly.

2. Roof Pitch and Accessibility

A steep or high-pitched roof is more difficult (and dangerous) to work on. Roofs that are hard to access may also require special equipment, which increases labor time and safety precautions.

Why it matters: More complexity = more time, gear, and labor.

3. Tear-Off vs. Overlay

If your existing roof needs to be completely removed (a tear-off), the labor and disposal costs will be higher than if a new roof is installed over the old one (an overlay). Most modern roofing jobs require a tear-off to meet building codes and ensure a long-lasting result.

Tear-offs add cost, but they offer better performance and lifespan in the long run.

4. Type of Roofing Material

Material choice has one of the biggest impacts on cost. Here's a general idea of price tiers (from most affordable to premium):

• Asphalt shingles – Cost-effective and common in Barrie.

• Metal roofing – More durable but comes at a higher upfront cost.

• Architectural shingles – Thicker and longer-lasting than standard asphalt.

• Slate, cedar, or composite – High-end options with significant cost increases.

Bonus: Ask about energy-efficient options that can reduce your long-term utility bills.

5. Underlayment and Ventilation Needs

Proper roofing isn't just about shingles. The underlayment, ice and water shield, drip edge, and ventilation upgrades all add to the overall cost—but they’re essential for protecting your home from leaks, rot, and mold.

Skimping on these areas may save now, but could cost much more later.

6. Flashing, Skylights, Chimneys & Extras

Have skylights, dormers, or chimneys? Any penetrations in your roof require additional flashing and sealing. Custom work in these areas can raise the overall price, especially if replacements or repairs are needed.

7. Disposal Fees and Clean-Up

Tearing off an old roof generates a lot of waste. A professional roofing company like CT Roofing Solutions includes dumpster rental, debris removal, and site cleanup in your quote, but it’s worth confirming to avoid hidden costs.

8. Labor and Warranty

Experienced, licensed roofers may charge more, but the quality of workmanship and warranty coverage are worth the investment. A cheaper quote might save money upfront but could lead to repairs or even premature replacement.

Always ask: Does the price include warranty-backed labor and materials?

9. Seasonal Demand in Barrie

Roofing prices can also fluctuate based on the time of year. Spring and fall are peak seasons, which may affect availability and pricing. Booking early or scheduling in the off-season (if weather permits) may offer better value.
