Choosing the right roofing material for your Calgary home is a decision that impacts not only your property’s appearance but also its protection against our unique climate challenges. As Calgary homeowners navigate between traditional asphalt shingles and increasingly popular metal roofing options, understanding the specific advantages and limitations of each in our local context becomes crucial.
This comprehensive guide will walk you through the key factors to consider when deciding between metal and asphalt shingles specifically for Calgary properties. We’ll examine how each material performs against our extreme weather conditions, evaluate long-term value, and provide a framework to help you make the best decision for your home and budget. By the end of this guide, you’ll have the knowledge needed to confidently choose the roofing material that best suits your Calgary home’s needs.
Understanding Calgary’s Unique Climate Challenges
Calgary’s climate presents specific challenges that directly impact roofing performance and longevity. When comparing metal vs. asphalt shingles, understanding how each material responds to our local weather conditions is essential for making an informed decision.
Extreme Temperature Fluctuations
Calgary experiences some of Canada’s most dramatic temperature swings, with variations of up to 30°C possible within 24 hours. These extreme fluctuations put significant stress on roofing materials through expansion and contraction cycles. Metal roofing generally handles these changes well, as quality metal systems are designed with fastening methods that accommodate movement. Asphalt shingles, however, can become brittle over time with repeated freeze-thaw cycles, potentially leading to cracking and reduced lifespan.
According to a 2024 study by the Alberta Building Envelope Council, roofing materials in Calgary experience approximately 120 freeze-thaw cycles annually, nearly 30% more than the national average. This makes material selection particularly important for long-term performance.
Hail Alley Considerations
Calgary sits in what meteorologists call “Hail Alley,” experiencing some of Canada’s most frequent and severe hailstorms. The devastating 2020 Calgary hailstorm caused over $1.3 billion in damage, much of it to roofing systems. When comparing materials, impact resistance becomes a critical factor for Calgary homeowners.
Modern metal roofing typically carries Class 4 impact resistance ratings (the highest available), making it exceptionally resistant to hail damage. Quality asphalt shingles can also achieve Class 4 ratings, though their impact resistance may diminish over time as the granular surface wears. Many Calgary insurance providers now offer premium discounts for homes with Class 4 rated roofing materials, regardless of whether they’re metal or asphalt.
Snow Load Requirements
Calgary receives an average annual snowfall of 128.8 cm, with heavy accumulations common during winter months. Both metal and asphalt roofing systems, when properly installed, are designed to handle Calgary’s snow load requirements as specified in the Alberta Building Code.
Metal roofing offers a slight advantage in snow management due to its smoother surface, which allows snow to slide off more easily, particularly on steeper pitches. This can reduce the weight burden on your roof structure during heavy snowfall periods. Asphalt shingles tend to hold snow longer due to their textured surface, which can be beneficial in preventing sudden snow slides near entrances but may require more structural support for the additional weight.
The right roofing material for your Calgary home isn’t just about aesthetics. It’s about choosing a system engineered to withstand our unique climate challenges while providing lasting protection for your investment.
Asphalt Shingles in Calgary: Pros and Cons
Asphalt shingles remain the most common roofing material in Calgary, adorning approximately 70% of residential properties according to a 2024 industry survey. Understanding their specific advantages and limitations in our climate is essential for making an informed decision.
Cost Considerations for Calgary Homeowners
The initial affordability of asphalt shingles makes them particularly attractive to many Calgary homeowners. Current market data shows installation costs ranging from $4-$6 per square foot for standard architectural shingles, significantly lower than metal roofing alternatives. For an average Calgary home (approximately 2,000 square feet of roofing), this translates to $8,000-$12,000 for a complete asphalt shingle installation.
This lower upfront investment must be balanced against the shorter lifespan in Calgary’s harsh climate. Most asphalt shingle roofs in our region last 15-20 years, though premium options with enhanced warranties may extend this to 25-30 years under ideal conditions. When calculating total lifetime costs, remember to factor in potential replacement needs within your homeownership timeline.
Durability Against Calgary Weather
Asphalt shingles have improved significantly in recent years, with manufacturers developing formulations specifically designed for extreme weather regions. For Calgary homes, experts recommend architectural (dimensional) shingles with a minimum weight of 240-340 lbs per square and Class 4 impact resistance ratings.
The granular surface of asphalt shingles provides good protection against UV radiation, which is particularly intense in Calgary due to our elevation and relatively thin atmosphere. However, these granules shed over time, gradually reducing the shingles’ protective capabilities against our intense summer sun and winter freeze-thaw cycles.
Calgary’s frequent hailstorms present a particular challenge. While impact-resistant asphalt shingles perform admirably when new, their resistance typically diminishes over time. After severe weather events, it’s advisable to have your asphalt roof inspected for damage that might not be immediately visible but could lead to leaks or reduced performance.
Installation Process and Timeline
One significant advantage of asphalt shingles for Calgary homeowners is the installation timeline. Most asphalt shingle roofs can be completely installed in 2-3 days, minimizing the period your home is vulnerable during our unpredictable weather seasons. The larger pool of qualified contractors in Calgary familiar with asphalt installation also means more competitive pricing and easier scheduling.
The ideal installation window for asphalt shingles in Calgary is between late spring and early fall when temperatures consistently remain above 10°C. Installation during colder periods can prevent proper sealing of the shingles, potentially reducing their wind resistance and longevity. Most reputable Calgary roofing contractors will advise against asphalt shingle installation during winter months for this reason.
Metal Roofing in Calgary: Pros and Cons
Metal roofing has gained significant popularity in Calgary over the past decade, with installations increasing by approximately 15% annually according to local industry data. This trend reflects growing awareness of metal’s performance benefits in our challenging climate.
Long-term Value and ROI
While metal roofing requires a higher initial investment, typically $10-$14 per square foot for quality standing seam systems in the Calgary market, its exceptional longevity offers compelling long-term value. Most properly installed metal roofs in Calgary will last 40-60 years with minimal maintenance, effectively outlasting 2-3 cycles of asphalt shingle replacement.
This extended lifespan significantly impacts the total cost of ownership calculation. A 2023 study by the Metal Roofing Alliance found that while metal roofing costs approximately 2-3 times more than asphalt shingles initially, the lifetime cost averages 30% less when factoring in replacement and maintenance expenses over a 50-year period.
Additionally, metal roofing can increase your Calgary home’s resale value. Local real estate data indicates homes with quality metal roofing systems command a premium of 1-2% compared to similar properties with asphalt shingles, partially offsetting the higher initial investment.
Performance in Calgary Storms
Metal roofing excels in Calgary’s storm-prone environment. Quality systems carry Class 4 impact resistance ratings that, unlike asphalt shingles, do not degrade over time. After the devastating 2020 hailstorm, insurance assessors noted significantly lower damage rates among homes with metal roofing compared to those with asphalt shingles.
Wind resistance is another critical factor in Calgary, where gusts regularly exceed 100 km/h during severe weather events. Standing seam metal roofing systems, with their interlocking panels and concealed fasteners, typically offer wind ratings of 140-180 km/h, well above the requirements specified in the Alberta Building Code for Calgary properties.
One common concern among Calgary homeowners is noise during rain or hailstorms. Modern metal roofing installations include solid decking and underlayment that significantly dampen sound transmission. When properly installed with these components, metal roofing produces only marginally more noise than asphalt alternatives during precipitation.
Energy Efficiency in Calgary’s Climate
Metal roofing’s energy performance offers particular advantages in Calgary’s climate extremes. During our intense summer days, metal roofs with reflective coatings can reduce cooling costs by 15-25% according to Natural Resources Canada data. This reflectivity helps maintain more comfortable interior temperatures during heat waves, which have become increasingly common in recent Calgary summers.
In winter, metal roofing’s smooth surface allows snow to slide off more readily, reducing the insulating effect of snow accumulation that can trap escaping heat. When combined with proper attic insulation and ventilation, this can contribute to more consistent energy performance year-round compared to asphalt alternatives.
Many metal roofing systems available in Calgary now come with ENERGY STAR certification, potentially qualifying homeowners for energy efficiency rebates through local utility programs or future provincial incentives.
Material Comparison: Feature-by-Feature
When evaluating metal vs. asphalt shingles for your Calgary home, comparing specific performance features helps clarify which material best aligns with your priorities and circumstances.
Lifespan Expectations in Calgary
The lifespan difference between these materials is substantial in Calgary’s climate. Quality metal roofing systems typically last 40-60 years, with manufacturers offering warranties of 30-50 years that often include coverage against fading and chalking. This extended lifespan means many Calgary homeowners will never need to replace a properly installed metal roof.
Asphalt shingles in Calgary generally last 15-20 years, though premium architectural shingles may reach 25-30 years under ideal conditions. Manufacturer warranties typically range from 25-30 years but often provide coverage after the initial period and may not account for our specific climate challenges. The practical implication is that a Calgary home built today will likely require 2-3 asphalt roof replacements over the same period a single metal roof would serve.
Maintenance Requirements
Maintenance needs differ significantly between these materials. Metal roofing in Calgary typically requires only periodic inspections (every 2-3 years) and occasional cleaning to remove debris from valleys and gutters. The smooth surface naturally resists moss and algae growth, common issues in some Calgary neighborhoods with mature tree coverage.
Asphalt shingles demand more regular maintenance, including annual inspections, prompt replacement of damaged shingles, and potential treatments for moss or algae growth in shadier locations. After severe weather events, which are common in Calgary, more thorough inspections are recommended to identify granule loss or hidden damage that could compromise the roof’s integrity.
For Calgary homeowners, this maintenance difference translates to both time and ongoing costs. Professional roof inspections typically cost $250-$450 in the local market, making the reduced frequency for metal roofing a notable long-term advantage.
Aesthetic Options for Calgary Homes
Both materials offer diverse aesthetic options to complement Calgary’s varied architectural styles, from heritage homes in communities like Hillhurst and Mount Pleasant to contemporary designs in newer neighborhoods like Nolan Hill and Panorama Hills.
Asphalt shingles come in numerous color blends and profiles, with architectural shingles creating dimensional shadows that mimic more expensive materials like slate or cedar. Recent innovations include designer shingles with distinctive patterns that can enhance curb appeal for relatively modest additional cost.
Metal roofing offers even greater design versatility, available in standing seam panels, metal shingles, and tiles that can emulate traditional materials. Color options are virtually unlimited, with specialized finishes that maintain their appearance longer than asphalt alternatives. For heritage homes in established Calgary neighborhoods, metal shingles designed to resemble historic materials can satisfy both aesthetic and performance requirements.
Calgary-Specific Considerations
Beyond general performance characteristics, several Calgary-specific factors should influence your roofing material decision.
Local Building Codes and Regulations
Calgary building codes include specific requirements for roofing materials related to fire resistance, wind uplift resistance, and structural loading. Both metal and asphalt options can meet these requirements when properly specified and installed, but certain neighborhoods or property types may have additional restrictions.
For homes in Calgary’s wildland-urban interface areas near Nose Hill Park or other natural spaces, fire resistance becomes particularly important. Metal roofing carries Class A fire ratings, providing maximum protection against windblown embers during wildfire season. While many asphalt shingles also achieve Class A ratings, their organic components make them inherently more combustible than metal alternatives.
Some Calgary communities with homeowner associations or architectural controls may have specific guidelines regarding roofing materials and colors. Before making your final decision, check whether your neighborhood has restrictions that might limit your options.
Insurance Premium Impacts
Insurance considerations have become increasingly important for Calgary homeowners following recent severe weather events. Many insurance providers now offer premium discounts for impact-resistant roofing materials, with potential savings of 5-25% on annual premiums depending on the carrier and specific policy.
Metal roofing typically qualifies for the maximum available discounts due to its superior hail resistance and durability. While impact-resistant asphalt shingles can also qualify for discounts, some insurers offer greater reductions for metal systems based on their proven performance in severe Calgary storms.
When evaluating roofing options, request specific information from your insurance provider about potential premium adjustments for different materials. These annual savings should factor into your total cost calculation, potentially offsetting a significant portion of metal roofing’s higher initial cost over time.
Neighborhood Aesthetics and Resale Value
While personal preference matters, considering how your roofing choice aligns with neighborhood aesthetics can impact both curb appeal and eventual resale value. In established Calgary communities like North Haven or Parkdale, where architectural styles tend to be more consistent, dramatic departures from prevailing roofing types might affect marketability.
Calgary real estate professionals report that metal roofing generally enhances property value in most neighborhoods, particularly when marketed with emphasis on its durability and weather resistance. The premium is typically most pronounced in higher-end communities and for properties where the metal roofing complements the overall architectural style.
For maximum resale benefit, consider roofing colors and profiles that harmonize with your home’s design while providing the performance benefits you need. Both metal and asphalt options offer sufficient variety to achieve this balance in most Calgary neighborhoods.
Real Calgary Homeowner Experiences
Examining actual outcomes for Calgary homes provides valuable insight beyond theoretical comparisons.
Case Studies: Metal Roof Performance
The Thompson family in Kincora installed a standing seam metal roof in 2018, just two years before the devastating 2020 hailstorm. While neighboring homes with asphalt roofing required complete replacement after the storm, their metal roof sustained only minor cosmetic denting that didn’t compromise its waterproofing integrity. Their insurance claim was minimal, and they avoided the stress and disruption of emergency roof replacement during a time when contractor availability was severely limited.
Another compelling example comes from a century home in Inglewood that received a metal shingle roof designed to complement its historic character. The owners report approximately 15% reduction in summer cooling costs since installation, attributing this to the roof’s reflective properties and improved ventilation design compared to their previous asphalt system.
Case Studies: Asphalt Shingle Performance
The Martinez family in North Haven installed premium architectural asphalt shingles with Class 4 impact resistance in 2019. During the 2020 hailstorm, their roof sustained some granule loss but remained functionally intact while many neighbors with standard shingles required complete replacement. Their experience highlights the significant performance difference between standard and premium asphalt products in Calgary’s climate.
For a more typical scenario, consider the Jackson family in Brentwood, who replaced their 18-year-old asphalt roof in 2023. The previous roof had reached the end of its functional lifespan after multiple repairs for wind damage and two shingle replacements following hailstorms. While they considered metal for the replacement, they ultimately chose premium architectural asphalt shingles again based primarily on the lower initial cost, accepting the likelihood of another replacement within their expected homeownership period.
Your Path Forward: Making an Informed Decision
With all factors considered, how do you determine which roofing material is right for your specific situation? The following framework can help guide your decision process.
Budget Considerations
Your available budget will significantly influence your options, but consider this decision in terms of total ownership costs rather than just initial investment. If you plan to remain in your home for 20+ years, metal roofing’s higher upfront cost may be offset by its longer lifespan and reduced maintenance requirements.
For those working with tighter initial budgets, premium architectural asphalt shingles with enhanced warranties and impact resistance offer a reasonable compromise between performance and affordability. Many Calgary roofing companies also offer financing options that can make metal roofing more accessible by spreading the investment over time.
When comparing quotes, ensure you’re evaluating comparable specifications and warranty coverage. The substantial price differences between basic and premium versions of both materials mean that accurate comparisons require detailed proposals specifying exactly what you’re receiving.
Long-term Planning
Your anticipated length of homeownership should heavily influence this decision. If you expect to sell within 5-10 years, the return on investment for metal roofing may be less compelling unless your neighborhood already has a significant percentage of metal roofs or you’re in a premium market segment where such upgrades are expected.
Conversely, if you’re planning to remain in your home indefinitely or pass it to family members, metal roofing’s extended lifespan and reduced maintenance requirements become more valuable. Many Calgary homeowners in their forever homes appreciate the peace of mind that comes with knowing they’ve installed what will likely be their last roof.
Consider also how your home’s other components align with your roofing choice. If you’re simultaneously upgrading to more durable soffits and fascia, the extended performance of metal roofing creates a more consistent overall exterior system.
Finding Qualified Calgary Contractors
Regardless of which material you choose, proper installation is crucial for optimal performance in Calgary’s challenging climate. When selecting a contractor, verify they have specific experience with your chosen material and can provide local references for similar projects.
For metal roofing in particular, specialized training and experience are essential. The performance advantages of metal systems depend largely on proper installation techniques, especially around flashings and penetrations. Request information about your contractor’s training credentials and manufacturer certifications for the specific metal system you’re considering.
With asphalt shingles, while installation may seem more straightforward, attention to details like proper nailing patterns and underlayment selection significantly impacts performance in Calgary’s high wind and extreme temperature conditions. Verify that your contractor follows manufacturer specifications precisely to maintain warranty coverage.
Always ensure your chosen contractor is fully licensed, insured, and familiar with Calgary’s specific building code requirements for roofing installations. Requesting proof of Workers’ Compensation coverage is particularly important for roofing projects due to the inherent risks involved.

Frequently Asked Questions
How much more expensive is metal roofing compared to asphalt shingles in Calgary?
In the Calgary market, metal roofing typically costs 2-3 times more than asphalt shingles for initial installation. Current pricing shows metal roofing ranging from $10-$14 per square foot installed, while asphalt shingles average $4-$6 per square foot.
However, when calculating lifetime costs over 50 years, metal roofing often proves 15-30% less expensive due to its longer lifespan and reduced maintenance requirements. For a typical Calgary home with 2,000 square feet of roofing, expect to invest $20,000-$28,000 for quality metal roofing compared to $8,000-$12,000 for architectural asphalt shingles.
How do metal and asphalt shingles compare for hail resistance in Calgary?
Both materials are available with Class 4 impact resistance ratings (the highest available), but they perform differently over time.
Metal roofing may dent during severe hailstorms but typically maintains its waterproof integrity even after impact. Its hail resistance doesn’t degrade over time.
Asphalt shingles with Class 4 ratings resist impact damage when new, but their resistance gradually diminishes as granules shed and the shingles age. After Calgary’s 2020 hailstorm, insurance data showed significantly lower replacement rates for metal roofing compared to even premium asphalt shingles of similar age.
Will metal roofing be too noisy during Calgary’s rain and hailstorms?
This is a common misconception. Properly installed modern metal roofing includes solid decking and underlayment that significantly dampen sound transmission. Studies show that metal roofing installed over proper substrate produces only 5-7 decibels more noise than asphalt alternatives during rainfall, a difference barely perceptible to most people. The exception would be metal installed on open framing (like in agricultural buildings), which does indeed produce significant noise during precipitation. For residential installations in Calgary, noise concerns should not discourage homeowners from choosing metal roofing.
How do Calgary’s winter temperatures affect these roofing materials?
Both materials are engineered to withstand Calgary’s extreme winter conditions, but they respond differently.
Metal roofing’s smooth surface allows snow to slide off more readily, reducing structural load during heavy accumulations. Its expansion and contraction during temperature swings are accommodated through proper fastening systems.
Asphalt shingles become more brittle in extreme cold, making them potentially more vulnerable to damage if walked on during winter maintenance. They also tend to hold snow longer, which can be beneficial for insulation but may require more robust structural support for the additional weight.
Can I install a metal roof over my existing asphalt shingles in Calgary?
While technically possible in some situations, this approach is generally not recommended for Calgary homes due to our extreme weather conditions. The Alberta Building Code allows for re-roofing over a single layer of existing shingles, but most qualified Calgary contractors advise complete removal of old materials before installing metal roofing. This allows for inspection and repair of the underlying deck, proper installation of ice and water shield (crucial in our climate), and ensures the new roof lies flat without telegraphing imperfections from the old surface. Complete removal also prevents potential moisture trapping between layers that could lead to deck deterioration over time.
