How much should I budget for asphalt shingle roof full in Ottawa?

A full asphalt shingle roof replacement in Ottawa typically costs between $8,000-$25,000, with most homeowners spending $12,000-$18,000 for a standard 1,500-2,000 sq ft home. The wide range depends on your roof size, shingle quality, complexity, and current roof condition.

Pricing Breakdown by Home Size:

• Small bungalow (1,000-1,200 sq ft): $8,000-$14,000


• Average two-story (1,500-2,000 sq ft): $12,000-$18,000


• Large home (2,500+ sq ft): $18,000-$25,000+

What Drives Costs Higher in Ottawa:
The biggest factor is shingle quality. Basic 3-tab shingles run $3-4 per sq ft installed, while architectural shingles cost $4-6 per sq ft, and premium impact-resistant or designer shingles can reach $7-10 per sq ft. Given Ottawa's harsh freeze-thaw cycles and significant snow loads, many contractors recommend architectural shingles as the minimum quality level for longevity.

Roof complexity significantly impacts pricing. Simple gable roofs are cheapest to replace, while homes with dormers, valleys, skylights, or steep pitches increase labor costs by 20-40%. Tear-off requirements also matter - if you have multiple layers of old shingles or need extensive deck repair, expect additional costs of $2,000-$5,000.

Ottawa-Specific Considerations:
Our climate demands proper ice dam prevention, which means adequate ventilation and potentially ice-and-water shield installation along eaves. Many Ottawa contractors include this automatically, but verify it's in your quote. The frost line depth of 4 feet doesn't directly affect roofing, but our temperature swings are particularly hard on roofing materials.

Timing affects pricing - book for late spring through early fall installation. Winter roofing is possible but costs 15-25% more due to weather challenges and material handling difficulties.

What's Typically Included:

• Complete tear-off of old materials


• New underlayment and ice-and-water shield


• Asphalt shingles and accessories


• Ridge cap and starter strips


• Basic flashing replacement


• Cleanup and disposal

Additional costs often include chimney flashing ($300-800), skylight flashing ($200-500 each), or structural deck repairs ($3-8 per sq ft).

Professional Guidance:
Always get three quotes from licensed, insured contractors with WSIB clearance. Verify they'll pull the required building permit (typically $200-400 for roof replacement). Avoid door-to-door contractors after storms - they're often unlicensed and may disappear before warranty issues arise.

Next Steps:
Measure your roof's footprint and multiply by 1.3-1.5 to account for slope and waste. Get quotes in early spring for summer installation, as quality contractors book up quickly. Verify each contractor carries liability insurance and provides written warranties on both materials and workmanship.
