When you’re looking into a residential roof replacement in Calgary, one of the first questions is: How much will it cost per square foot? The trust is, there’s no one-size-fits-all answer—by understanding the key factors that go into calculating the cost, you can make an informed decision and budget accordingly.
What Impacts the Cost of a Residential Roof Replacement in Calgary
There are several factors that go into the cost of a roof replacement in Calgary, including:
1. Material Type
- Asphalt shingles are the most common choice, and many Calgary homeowners see installed costs around $6.50 to $15.00 per square foot.
- Metal roofing costs more but lasts longer, saving you money over time. The approximate average cost is between $15 and $25 per square foot.
- Premium options, like slate or synthetic slate, can range between $15 and $80 per square foot, depending on materials and complexity of the job.
2. Roof Size & Pitch
Roof complexity plays a big role in the cost of a roof replacement in Calgary. Steeper roofs, multiple peaks, dormers, or skylights can all increase the cost of labour.
Roof size is another factor that can impact the cost. Many homeowners are surprised to learn that a 2,000 sq. ft. home doesn’t translate to 2,000 sq. ft. of roofing. Because of roof slopes, overhangs, and additional features such as dormers or multiple angles, the actual roof surface is often significantly larger.
3. Existing Roof Removal
If you’re tearing off your old shingles, disposal and removal can add to the cost of your residential roof replacement if it’s non-conventional. The structure of your existing decking may need to be removed as well, which will also factor into the overall cost. Wood shingles will cost more to remove than standard asphalt, or maybe even multiple layers of roofing material, which is not code nowadays.
4. Local Building Requirements
Calgary’s weather (hail, freeze-thaw cycles, heavy snow) demands quality underlayments, ice and water shields, and proper ventilation, all of which can impact building costs.
5. Labour Costs
Labour is a significant factor in the cost of a roof replacement in Calgary. Depending on the materials you choose and your roof design, labour can range between $2 and $6 per square foot.
Hidden Costs to Watch For
Aside from just materials and labour, there may be extra costs:
- Permits: Make sure you check whether permit fees are included in your quote.
- Disposal of Old Roofing Materials: Tear-off and bin rental aren’t always included by default. Discuss this with your contractor before signing on the dotted line.
- Structural or Deck Repairs: If the wood beneath your shingles needs replacing, that’s an additional cost. Be careful here, as most roofers will not tell you about the lifespan of plywood, which is only 40 years; there’s a good chance that all of your plywood will need a full new deck if your house is older than 30 years. Often, they’ll say nothing in fear that you won’t be able to afford the extra costs, and then you’ll be left holding the bag when your roof fails in the not-so-distant future.
- Ventilation, Flashing, and Underlayment: Because of Calgary’s climate, quality installations demand these components to help prevent leaks and ice damming. 90% of roofs aren’t vented correctly, and chances are good your roofer won’t correct it. Check for venting certifications, as it directly impacts not just the roof but the entire structure.
Why Investing Right Matters
Spending a little more per square foot now can protect you for decades. Here’s why:
- A well-installed roof with quality materials means fewer repairs in the future.
- Good underlayment and ventilation reduce the risk of ice dams, moisture damage, and insulation issues.
- Given Calgary’s extreme weather, durable materials (such as impact-resistant shingles or high-quality metal) can actually be more cost-effective in the long run.
- Proper installation by certified professionals protects your warranty, meaning better peace of mind.
