Calgary, AB Metal Roofing Review: Why We Chose an Interlock Aluminum Lifetime Roof to Replace Our Cedar Shakes
Calgary, AB
Darren and Lori
After careful consideration of the different roofing materials and styles available; we were convinced that the aluminum roof system offered by Interlock Metal Roofing (Alberta) Ltd. (hereafter referred to as “Interlock”) was the best choice for us.
Four years ago we moved into a 30-year-old home, which has been in the family since it was built. We knew that the original cedar shakes would need replacing; they had served the homes’ inhabitants well but were nearing the end of their ‘life expectancy’. We are a young family and so price was an important factor; however, we also plan on remaining in this house for many years to come. We decided that the investment in a “lifetime roof” was worth it for us, and we also appreciated the fact that it was more environmentally friendly than an asphalt roof.
Our roof was installed over the course of ten days, only delayed a few days by two major snowstorms. The installation crew, led by James, was wonderful. They worked long and hard each day, they were considerate, conscientious, and personable; I would recommend James to anyone interested in an Interlock roof.
Likewise, we appreciated your willingness, Joe, to work with us throughout the process. Your consideration of our queries and concerns was noted and valued.
We are the first homeowners, on our bay of ten homes, to re-roof from the original shakes; the black <a class="wpil_keyword_link" title="slate" href="” data-wpil-keyword-link=”linked”>slate design looks terrific…we will undoubtedly be fielding queries about your product and company!

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 in Calgary commonly last 40–70+ years, while asphalt shingle roofs typically last about 15–30 years depending on quality and installation. Calgary’s climate—cold, snowy winters with frequent freeze–thaw cycles, heavy snow loads and periodic hail, plus strong Chinook-driven temperature swings and high UV at elevation—places stress on roofing materials and can shorten asphalt lifespans while metal resists moisture, ice and impact better than shingles. Homeowners often choose durable metal systems for longer service life, lower maintenance, improved wind and hail performance, and better energy efficiency. Interlock Metal Roofing systems use heavy‑gauge aluminium and a lifetime limited 50‑year transferable warranty designed for long‑term protection.
How much does it cost to install a metal roof in Calgary, AB?
A metal roof in Calgary generally costs more upfront than asphalt shingles, but exact pricing depends on roof size, slope, complexity (hips, valleys), tear‑off, flashing, skylights, and labour. Calgary’s frequent hail and intense UV exposure can dent or degrade some materials, making metal a durable choice in this market. Dramatic freeze–thaw swings and Chinook temperature shifts also stress roofing materials and fasteners, affecting long‑term performance and installation requirements. Local construction factors (access, insulation, building code snow‑load requirements and labour rates) influence final cost. Many homeowners therefore compare options by lifetime value—higher initial cost for a metal roof can mean fewer repairs, less frequent replacement, and lower lifecycle cost. Interlock Metal Roofing focuses on long‑term ownership value and durability rather than positioning as the lowest‑cost roofing option.
Should I choose metal roofing or asphalt shingles for my Calgary home?
Metal vs asphalt in Calgary depends on priorities. Metal roofs typically last 40–70+ years versus 15–25 years for asphalt shingles (lifespan). Metal needs less frequent upkeep (periodic inspections, fastener checks) while shingles require more regular repair, granule loss monitoring and replacement sooner (maintenance). Metal offers superior impact, wind and snow performance—resisting hail dents and freeze–thaw damage better—while shingles are more prone to granule loss and cracking (durability). Long-term value: higher upfront cost for metal but lower life‑cycle and replacement costs can make it more economical over decades. Calgary’s strong freeze–thaw cycles, Chinook temperature swings and periodic hailstorms accelerate shingle wear and roof damage. Homeowners prioritising long-term protection and reduced maintenance often choose metal; others favour asphalt for lower initial cost. Interlock Metal Roofing appeals for lasting performance, improved resistance to local weather and strong architectural curb appeal.
Are metal roofs noisy when it rains in Calgary?
Are metal roofs noisy in Calgary, AB? This is a common myth. Modern residential metal roofs installed over solid decking and tied into the roof assembly do not sound like barn roofs. Sound depends on insulation, attic space, underlayment, and the full assembly; a well‑insulated ceiling and proper underlayment greatly reduce rain noise. Installation quality matters—secure fastening, correct spacing and proper flashings prevent vibration and rattling. Properly installed residential metal roofs are typically similar in sound to shingles or tile. Interlock Metal Roofing systems are installed as complete roofing systems designed for residential homes, including appropriate underlayments and attachment methods to minimise noise.
How energy-efficient are metal roofs in Calgary?
Yes — a metal roof can be energy efficient in Calgary, but results depend on design and context. Metal roofing can reflect sunlight and reduce summer heat gain when finished with reflective coatings. However, overall performance also depends on the roof assembly, quality of insulation and vapour control, and attic ventilation — these elements control heat loss in Calgary’s cold winters and heat flow in warm, sunny periods. Climate matters: Calgary’s temperature swings mean reflective benefits in summer and good thermal resistance in winter are both important. Homeowners researching roof replacement often prioritise energy efficiency to lower utility bills, improve year‑round comfort, extend roof life and boost resale value. Interlock Metal Roofing systems are designed to support long‑term home performance.
How does metal roofing in Calgary, AB withstand wind, hail, and severe weather?
Calgary faces frequent hailstorms, strong Chinook and thunderstorm winds, and heavy winter snowloads — all of which can stress roofs and flashings. Metal roofing performs well in wind and snow (sheds snow and resists uplift) and is often more impact‑resistant than conventional shingles, but real results depend on system design (profile, fasteners, underlayment), installation quality, and material/finish durability. Homeowners prioritise weather resilience to protect asset value, reduce repair and insurance costs, and limit downtime. Choosing tested profiles, high‑wind fastening patterns, impact‑resistant coatings and proper installation — plus post‑storm inspections — improves outcomes. Interlock Metal Roofing systems are engineered for durability, hail protection and wind resistance and, when specified and installed correctly, deliver strong long‑term performance in Calgary’s severe weather.
Will a metal roof rust or corrode in Calgary's wet climate?
Metal roofing performance depends on the type of metal: corrosion and rust resistance vary by material. Steel, galvanized or painted, offers strength but can corrode over time if coatings fail; stainless steel and aluminium are inherently more corrosion‑resistant. Aluminium performs particularly well in wet or coastal environments because it forms a protective oxide layer that resists rusting. Homeowners in Calgary, AB should consider corrosion resistance when selecting roofing materials to ensure long‑term durability, lower maintenance, better warranty performance and to protect property value against seasonal exposure. Interlock Metal Roofing systems use aluminium construction designed for strong corrosion resistance and are protected by the Alunar Coating System for extra protection against moisture, salt and environmental wear, providing extended service life and reduced maintenance needs.
How often should I inspect and maintain my metal roof in Calgary?
Metal roofing is generally a low‑maintenance choice for Calgary homeowners, thanks to durable coatings and long service life. That said, no roof is completely maintenance‑free. Inspect your roof periodically—after storms and at least seasonally—to spot loose fasteners, damaged flashings, scratched or worn coatings, and issues around chimneys, vents and skylights. Remove accumulated debris and clean gutters to prevent water backup and corrosion at eaves. Check flashings and sealant at penetrations and edges, and address any dents or seam separation promptly. Heavy spring runoff, hail, wind and winter ice can accelerate wear or dislodge debris, so inspect following significant weather events. Overall, metal roofs offer excellent longevity and low upkeep when inspected and maintained occasionally.
How does curb appeal affect my home's resale value in Calgary?
Yes. In Calgary, AB, metal roofing can increase home value. Buyers often value durable, low‑maintenance roofs that reduce future repair costs; premium roofing materials enhance curb appeal and perceived quality; and a long lifespan improves buyer confidence and can justify a higher asking price. Architectural style matters — a metal roof that complements the neighbourhood and the home’s character will add more value than one that looks out of place. Interlock Metal Roofing systems offer multiple architectural profiles: slate, cedar shingle, Mediterranean tile, shake and standing seam, available in heavy‑gauge aluminium and solid copper, so you can match local styles while delivering long‑term performance. Lower maintenance reduces expected labour and repair costs over time, a selling point for busy Calgary buyers. For precise resale impact, consult a local appraiser or real estate agent familiar with your neighbourhood.
Can I install solar panels on my Interlock Metal Roofing System in Calgary?
Calgary roofs are exposed to frequent hail and strong freeze–thaw cycles with sizeable winter snow loads and periodic high winds, all of which affect long‑term roof performance.
Yes — Interlock Metal Roofing Systems are compatible with solar when fitted with custom solar brackets installed by Interlock Metal Roofing (Alberta) Ltd. When comparing materials here, prioritise roof lifespan: solar panels are best mounted on durable roofs to avoid removing panels for mid‑life reroofs. If you plan solar later, choose long‑lasting materials now. Interlock’s metal systems are solar‑compatible and engineered to support approved solar mounting solutions, making them a strong choice for Calgary’s hail, snow and freeze–thaw conditions.
