			== Frequently Asked Questions ==

			=== How much does it cost to replace a roof? ===
			A typical asphalt shingle roof replacement runs roughly $5,000 to $15,000 for an average home, about $4 to $8 per square foot installed. Premium materials cost more: metal $8 to $16, tile $8 to $18, and slate $15 to $30 per square foot. Roof size, pitch, tear-off, and decking repairs drive the final price.

			=== How much does a new roof cost per square foot? ===
			Installed roofing typically costs $4 to $8 per square foot for asphalt shingles, $8 to $16 for metal, $8 to $18 for tile, and $15 to $30 for slate. Estimates often price by "square" (one square equals 100 sq ft), so a 20-square asphalt roof might run $8,000 to $16,000.

			=== Why are roof replacement estimates so different? ===
			Estimates vary with roof size and pitch, material and warranty tier, whether the old roof is torn off or overlaid, the condition of the decking, flashing and ventilation work, and regional labour rates. Compare line items rather than just totals, and confirm tear-off and underlayment are included.

			=== Is it cheaper to repair or replace a roof? ===
			Repair is cheaper short term and makes sense for isolated, recent damage on a roof with years of life left. Replacement is more cost-effective when the roof is near the end of its lifespan, has widespread damage, or needs repeated repairs, since you avoid paying twice and reset the warranty.

'''How much does a new roof cost?''' In 2026, a new asphalt-shingle roof on a typical North American single-family home costs between '''$8,500 and $18,000''' installed, while premium materials such as [[Metal Roofing|metal]], [[Slate Roofing|slate]], or [[Tile Roofing|tile]] can push the total to '''$25,000–$70,000+'''. The final price depends on material, roof size and pitch, tear-off requirements, decking repairs, local labour rates, and the complexity of flashing, venting, and trim work. This guide breaks down what drives the cost, how to read a quote, and what a reasonable 2026 budget looks like for each common scenario.

== Average Roof Replacement Cost in 2026 ==

The most widely cited benchmark is '''cost per roofing square''' — one square equals 100 square feet of roof surface. A typical two-storey 2,000 sq ft house has roughly 20–25 roofing squares once pitch and overhangs are factored in. See [[How to Calculate Roofing Materials]] for the measurement method.

|}

These ranges assume a straightforward single-layer tear-off and replacement. Complex roofs, steep pitches, and extensive repairs add materially to the total — often 15–35% on top of the baseline. The [[Roof Repair Costs|Roof Repair Costs]] article covers isolated repair pricing rather than full replacement.

== What Drives the Cost of a New Roof ==

[[File:roof-cost-factors-diagram.png|thumb|right|alt=Diagram showing the main factors that drive roof replacement cost|The seven factors that determine a roofing quote]]

=== Roof Size (Square Footage) ===

The total area of your roof is the single biggest driver of cost. Because materials and labour are both priced per square, doubling the roof size roughly doubles the price. Measuring is not as simple as reading the footprint of your house — pitch, eaves, dormers, and gables all add area. Use the method in [[How to Calculate Roofing Materials]] to estimate squares before you request quotes.

=== Material Choice ===

Material is the second biggest lever. A mid-range architectural shingle roof on a 25-square home lands around $14,000; the same roof in standing-seam metal can exceed $35,000. Longer-lived materials cost more up front but usually beat shingles on lifetime cost per year. See [[Roofing Materials Comparison Chart]] for side-by-side lifetime economics.

=== Roof Pitch and Accessibility ===

[[Roof Pitch|Steeper pitches]] (above 7/12) require harnesses, additional staging, and slower installation, typically adding 20–35% to labour. Low-slope and flat sections call for different materials entirely — usually a [[Single-Ply Roofing Membranes|single-ply membrane]] or [[Modified Bitumen Roofing|modified bitumen]] system. Multi-storey homes and homes with limited driveway or yard access also push the price up.

=== Tear-Off vs Overlay ===

A full tear-off — stripping down to the decking — costs more than a shingle-over installation but is almost always the right choice. Overlay roofs add weight, hide rotted decking, and shorten the life of the new material. [[Can You Put New Shingles Over Old Ones]] covers when an overlay is acceptable (rarely) and when code prohibits it.

=== Decking Condition ===

If the contractor finds soft or rotted [[Roof Deck|sheathing]] after the tear-off, replacement plywood or OSB is billed as an extra — typically '''$70–$120 per 4x8 sheet''' installed. Most quotes include an allowance for 2–4 sheets; anything beyond that is an upcharge. This is the number-one source of surprise overruns on otherwise straightforward jobs.

=== Flashing, Venting, and Accessories ===

A roof is more than shingles. A complete replacement usually includes new [[How to Install a Drip Edge|drip edge]], [[How to Install Ridge Cap Shingles|ridge cap]], [[How to Repair Roof Flashing|step and chimney flashing]], ice-and-water shield at eaves and valleys, [[Roof Underlayment Guide|synthetic underlayment]], and replacement of pipe boots and [[Roof Ventilation|ridge/soffit vents]]. Reusing old flashing is a red flag on any quote and a common cause of leaks within two years of installation.

=== Labour and Regional Rates ===

Labour accounts for '''40–60%''' of a residential roofing quote. Rates vary widely by market: Toronto, Vancouver, New York, and the San Francisco Bay Area are typically 25–45% more expensive than mid-size Midwest or Prairie cities. Calgary, Edmonton, and Winnipeg sit near the national average, while Halifax and Saskatoon are often on the lower end. See [[Top 5 Roofing Companies in Calgary]] for local rate context.

=== Warranty Tier ===

Most shingle manufacturers (GAF, Owens Corning, CertainTeed, IKO, Malarkey) offer a base limited warranty on materials alone, plus extended workmanship-inclusive warranties that require the contractor to be factory-certified. Upgrading to a 50-year transferable workmanship warranty typically adds '''$500–$1,500''' to a shingle job but substantially improves resale and claim handling. See [[Roof Warranties Explained]] and [[What Voids Your Roof Warranty]].

== Cost by House Size ==

These are installed-cost ranges for a complete replacement in mid-range architectural asphalt shingles, assuming a standard gable or hip roof with one layer torn off.

* '''1,000 sq ft bungalow (≈13 squares):''' $6,500 – $10,500
* '''1,500 sq ft single-storey (≈18 squares):''' $8,500 – $14,000
* '''2,000 sq ft two-storey (≈22 squares):''' $10,000 – $17,000
* '''2,500 sq ft home with dormers (≈28 squares):''' $13,000 – $22,000
* '''3,500+ sq ft custom home (≈40+ squares):''' $20,000 – $38,000+

For heavier materials, multiply the architectural-shingle range by: metal 1.6×, cedar 1.8×, tile 2.2×, slate 3.0×.

== Hidden Costs to Budget For ==

Even a well-written quote can miss some items. Budget a 10–15% contingency for:

* '''Decking replacement beyond the included allowance''' (see above)
* '''Chimney rebuilds or flashing reconstruction''' — an old brick chimney with crumbling mortar often needs masonry work before new flashing can be installed
* '''Skylight replacement''' — skylights older than 15 years should generally be replaced during the re-roof rather than re-flashed
* '''Permit fees''' — typically $100–$500 depending on municipality; see [[Roofing Building Codes and Permits]]
* '''Dumpster and disposal''' — most quotes include this, but confirm it is itemized
* '''Gutter and fascia work''' — often discovered once the old roof is removed
* '''Ventilation upgrades''' — older homes frequently have inadequate [[Roof Ventilation]] that a quality installer will insist on correcting

== How to Reduce the Cost Without Cutting Corners ==

* '''Get at least three written quotes''' from contractors who carry proper insurance and licensing. See [[How to Choose a Roofing Contractor]].
* '''Schedule in the shoulder season.''' Contractors are often willing to reduce margin in late fall and early spring when crews have open dates. See [[What Time of Year Is Best to Replace a Roof]].
* '''Choose architectural over designer shingles.''' Designer shingles add visual interest but typically 40–60% to the shingle line item for a performance benefit most buyers cannot detect.
* '''Bundle gutters, fascia, and soffit with the roof.''' A single mobilization is cheaper than separate jobs.
* '''Avoid overlay shortcuts.''' A shingle-over that fails at year 10 costs more than the tear-off you declined.
* '''Ask about manufacturer rebates.''' GAF, Owens Corning, and CertainTeed periodically run homeowner rebate programs administered through their certified contractors.

== Does Insurance Pay for a New Roof? ==

Homeowner insurance typically covers roof replacement caused by '''sudden, accidental events''' — hail, wind, fallen trees, and fire — but not wear-and-tear or age-related failure. Policies are increasingly shifting from replacement-cost to actual-cash-value coverage for roofs over 15 years old, which can leave homeowners with significant out-of-pocket depreciation. Detailed guidance is in [[Does Homeowner Insurance Cover Roof Replacement]] and [[How to Document Roof Damage for Insurance]]. For hail-specific claims see [[Hail Damage and Roofing]].

== Financing a New Roof ==

Most homeowners pay for a replacement through one of four channels:

# '''Cash / savings''' — always the cheapest option, eliminates interest
# '''Home equity line of credit (HELOC)''' — usually the lowest-interest financing available for a capital repair
# '''Manufacturer-backed financing''' — GAF, Owens Corning, and CertainTeed partner with lenders like GreenSky and Synchrony to offer 12–84 month terms, sometimes with a promotional 0% window
# '''Contractor in-house financing''' — convenient but usually the most expensive; always compare the effective APR to a HELOC before signing

== When to Replace vs Repair ==

A full replacement is worth the cost when the roof is past 75% of its expected lifespan, has multiple leak sources, shows widespread granule loss or curling shingles, or has decking damage. Isolated problems — a lifted flashing, a handful of cracked shingles, a single punctured vent boot — are almost always cheaper to repair. The decision framework is in [[Roof Repair vs Replacement]] and the warning signs are covered in [[Signs You Need a New Roof]].

== How to Read a Roofing Quote ==

A credible roofing quote in 2026 should itemize:

* Tear-off scope (layers removed, disposal included)
* Underlayment type and brand ([[Roof Underlayment Guide|synthetic vs felt]])
* Ice-and-water shield coverage (eaves, valleys, penetrations)
* Shingle or membrane brand, line, and colour
* Flashing (new vs reused — reject reused)
* [[Roof Ventilation|Ventilation]] plan and components
* Decking allowance (sheets included) and per-sheet overage rate
* Permit responsibility
* Workmanship warranty length and transferability
* Manufacturer warranty tier
* Payment schedule

If any of those line items are missing, ask for them in writing before signing.
