Calgary, AB Metal Roofing Review: Professional Interlock Installation Replacing Old Cedar Shake Roof
Calgary, AB
Merv S.
All Interlock personnel we dealt with were personable, courteous and professional. The installer (whose name I don’t recall) was a very able, diligent and hard worker. When he had helpers onsite – primarily for stripping the old shake and asphalt roof materials – they also worked well and without loud music or coarse language. Also, our contact at Interlock’s office (Shawna) was courteous and helpful – even to lending us the heavy material display panel from the showroom to take home for a weekend AND helping me load it in my car! We’ve had positive comments from neighbors and from passers-by when we’re outside. One of the more interesting was, “We loved the look of your old cedar <a class="wpil_keyword_link" title="shake" href="” data-wpil-keyword-link=”linked”>shake roof and were afraid what you might be replacing it with, but it looks great – good choice!

Top 10 Metal Roofing FAQs for Homeowners in Calgary
Homeowners researching metal roofing in Calgary often have several important questions before replacing their roof. Many people want to understand how metal roofing compares to traditional materials like asphalt shingles in terms of lifespan, durability, cost, and long-term value. Roofing decisions can also be influenced by local weather conditions. Homes in Calgary may experience environmental factors such as rain, wind, snow, heat, fire, or seasonal storms that can impact roof performance over time. The following frequently asked questions help explain what homeowners should know when evaluating metal roofing and why many people choose durable roofing systems designed for long-term protection.
How long will a metal roof last in Calgary, AB?
Metal roofs commonly last 40–70+ years, while asphalt roofs usually have much shorter lifespans (often 15–25 years). In Calgary, two local factors that affect roofing longevity are frequent severe summer hailstorms and strong freeze–thaw temperature swings (including Chinooks). Hail can dent or tear softer materials, and repeated thaw/freeze cycles stress seals and shingles, accelerating deterioration. Metal roofing resists hail impacts, shed snow, and tolerates thermal cycling better than asphalt, so homeowners often choose durable metal systems for long-term protection and lower life‑cycle costs. Interlock Metal Roofing systems use heavy‑gauge aluminium and come with a lifetime limited 50‑year transferable warranty designed to provide long‑term protection in Calgary’s challenging climate.
How much does it cost to install a metal roof in Calgary, AB?
Metal roofs in Calgary typically cost more upfront than asphalt shingles, but final price varies widely and depends on roof size, slope, complexity (hips, valleys), tear‑off, flashing, skylights and labour. Calgary’s frequent hail events and high‑wind exposure, plus winter freeze–thaw and snow events, influence material choice and installation details (stronger fastenings, underlayment and flashing), so local conditions can raise costs and affect long‑term performance. Many homeowners compare options on lifetime value rather than initial price: durable metal systems often reduce future repair and replacement costs. Interlock Metal Roofing emphasises long‑term ownership value and performance rather than competing as a low‑cost roofing option.
Should I choose metal roofing or asphalt shingles for my Calgary home?
Calgary’s climate—frequent severe hail and high‑wind events and significant freeze–thaw cycles/rain‑on‑snow that increase snow loads—directly affects roof performance.
Lifespan: metal roofs typically last 40–70+ years; asphalt shingles generally 15–25 years in Calgary’s conditions. Maintenance: metal needs less routine upkeep (occasional fastener/flashings check); shingles need more frequent repairs and replacement after hail or heavy freeze–thaw stress. Durability: metal resists moisture, ice and wind better and is less prone to granule loss from hail; shingles are more vulnerable to granule loss, curling and ice‑dam damage. Long‑term value: metal has higher upfront cost but lower life‑cycle and replacement costs and often better resale value and insurance outcomes for hail‑prone areas.
Homeowners who prioritise durability and long‑term protection often choose metal roofing. Interlock Metal Roofing appeals in Calgary for its long service life, strong weather resistance and architectural curb appeal.
Are metal roofs noisy when it rains in Calgary?
This is a common myth. Modern residential metal roofs installed over solid decking do not sound like barn roofs; they sit on continuous sheathing and underlayments that reduce noise. Sound from rain depends more on the roof assembly—insulation, attic space and underlayment—than the cladding itself. A ventilated, insulated attic and proper underlayment will make a metal roof sound similar to asphalt, tile or cedar. Installation quality matters: correct fastening, flashings and a complete system reduce vibration and noise. Properly installed residential metal roofs are typically similar in sound to other roofing materials. Interlock Metal Roofing systems are supplied and installed as complete roofing systems designed specifically for residential homes.
How energy-efficient are metal roofs in Calgary?
A metal roof can be energy efficient in Calgary. Metal roofing reflects sunlight, reducing summer heat gain when paired with reflective finishes, but overall performance depends on the whole roof assembly: underlayment, insulation levels and ventilation control heat flow and moisture year‑round. Because Calgary experiences cold winters, bright sunny days and large diurnal swings, reflective metal helps reduce cooling demand while proper insulation and ventilation prevent heat loss and condensation in winter. Homeowners researching roof replacement often prioritise energy efficiency to lower utility bills, increase indoor comfort, prolong roof life and boost resale value. When evaluating options, consider colour/finish, R‑value and ventilation strategy. Interlock Metal Roofing systems are engineered to support long‑term home performance.
How does metal roofing in Calgary, AB withstand wind, hail, and severe weather?
Calgary, AB sits in Canada’s “Hail Alley” and routinely experiences severe hail, strong thunderstorm winds and chinooks that can stress roofs and flashing.
Metal roofing can perform very well in these conditions: interlocking panels resist wind uplift, metal resists penetration from hail better than many organic coverings (though denting can occur with very large hail), and smooth metal sheds heavy rain and snow effectively when flashings and underlayments are correct. Actual performance depends on roofing system design, installation quality and material durability. Homeowners prioritise weather resilience to protect the structure, minimise repair costs and maintain insurance eligibility. Interlock Metal Roofing systems are engineered specifically for durability, hail protection and wind resistance, but benefits are only realised with proper design and professional installation.
Will a metal roof rust or corrode in Calgary's wet climate?
Corrosion and rust resistance in metal roofing vary by metal type. Steel, copper, zinc and aluminium each perform differently: some alloys and coatings offer greater corrosion resistance. Aluminium performs particularly well in wet or coastal climates because it forms a protective oxide layer that resists rust. Homeowners should prioritise corrosion resistance to extend roof life, reduce maintenance and avoid leaks, discolouration and fastener failure—especially in Calgary’s freeze‑thaw and precipitation cycles. Interlock Metal Roofing Systems use aluminium construction engineered for strong corrosion resistance and are finished with the Alunar Coating System for extra protection against moisture, salts and environmental wear. Choosing corrosion‑resistant materials lowers long‑term repair and replacement costs while maintaining appearance and performance.
How often should I inspect and maintain my metal roof in Calgary?
Metal roofing in Calgary, Alberta is generally considered a low‑maintenance option due to durable materials and interlocking panels. However, no roof is completely maintenance‑free: homeowners should inspect their roofs periodically—after heavy storms, significant snowfall melt, or seasonal debris buildup. Check for accumulated debris, clear gutters and downspouts, inspect flashing around chimneys, vents and eaves, and examine roof penetrations, fasteners and sealants for corrosion or loosening. Weather events such as hail, high winds and rapid freeze–thaw cycles can cause damage or dislodge panels, and spring/summer tree debris can clog gutters. With routine inspections and prompt minor repairs, metal roofs remain a long‑lasting, low‑maintenance choice for Calgary’s climate.
How does curb appeal affect my home's resale value in Calgary?
In Calgary, AB, metal roofing can increase home value because buyers consistently favour durable, low‑maintenance roofs that reduce future expense and hassle. Premium roofing materials also boost curb appeal, making a strong first impression on neighbourhood streets where architectural style matters — a modern standing seam may suit newer infills, while a slate or cedar look fits established communities. The long lifespan of quality metal systems improves buyer confidence, especially in Alberta’s climate. Interlock Metal Roofing systems offer multiple architectural profiles — slate, cedar shingle, Mediterranean tile, shake and standing seam — and are available in heavy‑gauge aluminium and solid copper, giving sellers design flexibility alongside proven performance. That combination often translates to stronger offers and faster sales in Calgary’s resale market.
Can I install solar panels on my Interlock Metal Roofing System in Calgary?
Yes — Interlock Metal Roofing Systems are compatible with solar panels in Calgary when custom solar brackets installed by Interlock Metal Roofing (Alberta) Ltd. are used. Because Calgary experiences frequent hail and strong Chinook winds that drive freeze–thaw cycling, choose durable roofing and mounting hardware to protect panels and attachments. Roof lifespan matters: long-lasting materials like Interlock’s metal reduce the chance of removing panels for reroofing. Homeowners replacing a roof should factor in future solar plans and request solar-ready detailing and warranties. Overall, Interlock systems are designed to support solar mounting solutions and are often preferred over shorter-lived materials for long-term installations.
