Why Asphalt Shingles Are Popular in Calgary
Choosing the right roofing material for your Calgary home involves understanding how it performs under Alberta’s extreme weather shifts, including bitter winters and unpredictable hailstorms. Asphalt shingles consistently remain the top choice among local homeowners due to their balance of affordability, performance, and visual appeal. Over 60% of residential roofs in Calgary feature asphalt shingles—this popularity stems from practicality, not just tradition.
Weather resilience and insulation value
Calgary’s climate presents unique challenges for any roofing system, particularly the frequent freeze-thaw cycles from late fall to early spring. Asphalt shingles provide effective protection against this stress due to their flexibility and layered sealing design. When paired with proper underlayment and attic insulation, asphalt shingles can contribute to improved energy efficiency, helping homeowners regulate indoor temperature and reduce heating costs.
Affordability and availability of products
Asphalt shingles remain one of the most cost-effective roofing options in Calgary. With widely available brands like IKO Cambridge and GAF Timberline, local roofing contractors can easily source products in bulk, keeping material costs reasonable for consumers. Their ease of installation also reduces labour costs, making replacement more accessible for homeowners dealing with storm damage or aging roofing systems.
Colour and aesthetic versatility for Calgary homes
From modern infills in Inglewood to heritage homes in Mount Royal, asphalt shingles offer aesthetic options that blend with Calgary’s diverse housing styles. Available in a variety of colours—black, charcoal, slate gray, and neutrals like weathered wood—these shingles enhance curb appeal while complementing exterior finishes like stucco, brick, or composite siding. This versatility makes them a go-to choice whether you’re replacing damaged shingles or upgrading your entire roof.
With durability, value, and style on its side, asphalt shingle roofing delivers trusted performance for Calgary’s demanding climate and architecture.
Signs You Need to Replace Asphalt Shingles
Aging asphalt shingles on a Calgary roof show visible damage, highlighting the need for timely replacement to protect your home.
Are you wondering whether your asphalt shingle roof is due for replacement? Calgary homeowners should stay vigilant. Cold snaps, hailstorms, and age-related wear can all contribute to early shingle deterioration—especially when your roof starts pushing the 15- to 20-year mark. Signs of trouble often appear well before a leak reaches your ceiling.
Curling or buckling shingles
Shingles that curl upward or buckle in the middle are no longer providing a proper water seal. In Calgary’s freeze-thaw cycles, water can enter beneath these warped sections, freeze at night, and cause further lifting. This is not just an eyesore—it’s a vulnerability that invites leaks or ice damming during snowmelt.
Missing granules and bald spots
The coarse, sand-like granules on an asphalt shingle protect it from UV deterioration. Once these granules begin shedding extensively—visible in gutters or as smooth bald patches—it’s a sign your roof surface is breaking down. Calgary’s summer hail events often accelerate this condition, even if the shingles appear intact from the ground.
Leaks, attic moisture, and ceiling stains
Interior water intrusion often begins subtly, showing up as faint ceiling stains or musty attic smells. Left untreated, even minor leaks caused by compromised shingles can lead to deeper issues like mould growth and insulation failure. A proactive inspection right after major weather events can catch moisture damage before permanent repairs are needed.
Hail or wind damage from Calgary storms
“Calgary experiences over a dozen hailstorms annually—prompt inspections save on costly repairs.”
Hail impacts often leave dimpled, bruised shingles that absorb water without obvious signs. Similarly, high winds common in Chinook conditions can lift and dislodge shingle layers, weakening the entire roofing system. After every major storm, a professional inspection is crucial—even if your roof looks fine from below.
Noticing any of these signs? Don’t wait—early roof assessments prevent larger expenses later.
Average Cost of Asphalt Shingle Replacement
Visualizing roofing upgrades: comparing asphalt shingle replacement options for homes in Calgary.
If you’re budgeting for a full roof replacement in Calgary, understanding current asphalt shingle pricing can help you plan with confidence. While costs vary based on home size and roof complexity, most local homeowners can expect quotes in the $6,500 to $11,000 range in 2024. Prices reflect a mix of labour, materials, access challenges, and the shingle brand selected.
Cost per square foot in Calgary (2024 rates)
On average, asphalt shingle replacement in Calgary runs between $4.50 and $6.50 per square foot, including tear-off, disposal, underlayment, shingle installation, and cleanup. This rate can climb to over $7.50 per square foot for premium upgrades such as architectural shingles or Class 4 impact-resistant options preferred for hail-prone zones.
Factors influencing price (labour, pitch, brands)
Prices rise with steeper roof pitches, multi-level homes, and harder-to-access valleys or dormers. Labour accounts for up to 60% of the project cost, especially when fall-arrest safety gear and scaffolding are required. Material choices like IKO Cambridge or GAF Timberline also affect costs—with higher impact resistance and colour retention often demanding premium-tier pricing.
Cost breakdown: materials vs. installation
Material expenses typically make up 40% of the total cost. This includes shingles, synthetic underlayment, ice and water shield, flashing replacement, and ventilation upgrades. The remaining 60% goes to skilled labour, site protection, removal of the old roofing system, and final inspections. A detailed quote from a trusted roofing contractor in Calgary should outline both components clearly.

Step-by-Step Replacement Process
Replacing asphalt shingles on a Calgary home requires precision, planning, and experienced craftsmanship. When you hire Impress Roofing & Exteriors, you’re not just getting new shingles—you’re getting a proven, code-compliant process that withstands Alberta’s unpredictable weather. Here’s what to expect when entrusting your roof to Calgary’s preferred asphalt shingle replacement specialists.
Initial roof inspection and measurement
Before any materials are removed, our Calgary crews begin each project with a comprehensive 30-point roof inspection. This includes identifying hail damage, measuring slope and deck spacing, checking attic ventilation, and marking potential leak points. We take detailed photos for documentation and ensure surrounding landscaping is protected before the tear-off phase begins.
Removing the old shingles and nails
The removal phase involves stripping all old shingles, nails, and underlayment down to the decking. We use safety gear, disposal trucks, and heavy-duty tarps to prevent debris damage.
A skilled roofer from Impress Roofing & Exteriors handles asphalt shingle replacement in Calgary with care and expertise.
Proper disposal ensures no loose nails or scrap materials are left behind, setting the foundation for a brand-new, lasting roof system.
Installing underlayment and new flashing
With a clean deck, our roofers install high-performance underlayment that complies with Calgary building code roofing requirements—including water shields in vulnerable valley areas and eave edges. New flashing is integrated around chimneys, skylights, and roof walls to seal these critical transition zones. Precision flashing and barrier prep prevent leaks—even during Calgary’s intense hailstorms.
Laying new asphalt shingles with ventilation
We then install high-quality, Calgary-rated asphalt shingles using manufacturer-recommended nailing patterns and spacing. Ridge vents or box vents are added or upgraded as required, ensuring air flows freely through the attic and prolongs shingle lifespan. Each layer is aligned to protect your home against wind-driven rain, snowmelt, and ice dams.
Peace of mind begins with a roof built on process. From inspection to installation, Impress Roofing handles every shingle replacement with precision and pride in Calgary.
Choosing the Right Roofing Contractor in Calgary
Selecting the right roofing contractor in Calgary is the difference between long-term protection and future headaches. Don’t get swayed by low bids or out-of-town storm chasers promising quick fixes. Instead, work with a licensed, local roofing company that backs every shingle replacement with warranties, insurance, and Alberta-specific knowledge.
What makes a roofer trustworthy
Reliable roofing contractors in Calgary are licensed, insured, and carry WCB coverage for all crew members. They use building code-compliant materials and submit municipal permits when required.
At Impress Roofing, every project includes a 10-year workmanship warranty and verified certifications.
This level of coverage protects both your home and your investment.
Questions to ask during estimates
- Are you local to Calgary and familiar with city-specific roofing codes?
- Can I see proof of liability insurance and WCB coverage?
- What brand of shingles do you recommend, and why?
- Is clean-up and disposal included in your quote?
- Do you provide a written workmanship warranty?
Transparency during quoting is a strong indicator of how the rest of the job will go. Don’t hesitate to request references or review past Calgary roofing jobs.
Avoiding roofing scams or unlicensed work
Unfortunately, Calgary sees its share of transient contractors after hailstorms. Red flags include cash-only pricing, no business registration, vague warranties, and pressure to decide without a contract. Homeowners should always request a written estimate and proof of liability coverage.
Impress Roofing & Exteriors is deeply rooted in Calgary—serving homeowners with integrity, professionalism, and unmatched shingle workmanship.
Calgary Roofing Codes, Permits & Compliance
Replacing your roof isn’t just about materials—it’s also about legal compliance. Calgary homeowners must adhere to strict permit guidelines and roofing regulations set by municipal and provincial authorities. Whether you’re replacing damaged shingles or upgrading for resale, knowing what’s required will prevent fines or failed inspections.
Permit requirements for roof replacement
If you’re replacing a roof in Calgary, permits are required when structural or ventilation upgrades are involved. City of Calgary roofing regulations expect contractors to pull permits before work begins. This ensures proper documentation, waste disposal, and future insurance eligibility. Homeowners managing their own projects are still subject to all permit rules.
Calgary-specific code compliance (ventilation, flashing)
The Calgary Building Code outlines specifications for ridge venting, eave protection, drip edge flashing, and underlayment installation. For example, all homes in hail-prone zones must include weatherproof membranes and peel-and-stick flashing barriers.
City of Calgary Roofing Guidelines mandate specific underlayments, edge flashings, and vents.
Roofing that fails to meet these standards can invalidate warranties—even manufacturer ones.
Inspection timelines and enforcement
City inspectors may visit during or after your roofing project to verify permit postings, ventilation improvements, and drainage slope. If work does not pass, delays or corrections are required. Impress Roofing manages compliance on your behalf, ensuring smooth start-to-finish results.
Don’t risk fines or denied coverage. Impress Roofing ensures all Calgary roofing work complies with the latest code updates and inspection logs.
Best Time of Year for Asphalt Shingle Replacement in Calgary
Timing your asphalt shingle replacement in Calgary is key to long-term performance and fewer delays. Alberta’s weather swings make spring and early summer the best months to re-roof. Choosing the optimal window minimizes exposure to rain, hail, or sudden early frost while giving roofers more working daylight. Here’s what local homeowners should consider.
Why spring and early summer are ideal (temperature, supply)
April through June feature consistent mid-temperature ranges of 10°C to 20°C, making conditions perfect for adhesive bonding and proper shingle installation.
April through June are historically the most stable roofing months in Calgary.
Material supply chains are also strongest early in the season, when manufacturers prepare for the annual roofing surge.
Risks of winter work or late fall installations
Installing shingles when temperatures are below 4°C can prevent the self-sealing strip from adhering properly. Snow, ice dams, and short days also make winter roofing dangerous and inefficient. Falls or misinstalls during frosty conditions can shorten shingle lifespan dramatically. Fall projects are possible—but must be completed before temperature dips consistently low.
Booking ahead to avoid delays
During hail season, many Calgary contractors become backlogged. To guarantee materials and lock in spring pricing, it’s wise to book your replacement as early as March or April.
Schedule early to beat the post-hailstorm rush and avoid material shortages.
Get on our schedule before the first warm spell hits—Impress Roofing ensures your Calgary home is ready for every season.
