Calgary, AB Aluminum Shingles Review: 3 Years of Maintenance‑Free Interlock Roofing Installation Satisfaction
Calgary, AB
John K.
I did a lot of research prior to selecting Interlock roofing. There are an abundance of good roofing material on the market but I was looking for a very long term and maintenance free product. Interlock offered an excellent product and a great warranty.
Their installers showed up on time, were very professional and courteous, and did the job within the estimated time schedule and price. Before the job was even started a few things were pointed out which required some slight roof modifications and venting changes. This was explained to me in a very professional and understanding way. Any sections of underlying plywood which were not up to standard were also replaced at the agreed upon price. Before any changes were made I was shown the reason why and I gave approval prior to proceeding.
I am very happy with the installation and product and would definitely endorse an installation through Interlock. I waited 3 years before writing this review because I wanted to make sure everything worked properly without any call backs.

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 shingles typically have shorter lifespans (often ~15–25 years). Calgary is prone to large hailstorms that can dent or puncture roofing materials and to rapid freeze–thaw cycles that accelerate cracking and material fatigue. Strong Chinook winds, heavy snow loads and wide temperature swings further stress fasteners and seams, so durable, impact‑resistant systems better preserve service life. Homeowners often choose metal for its longevity, hail resistance, low maintenance and improved energy performance under Calgary’s variable conditions. Interlock Metal Roofing systems use heavy‑gauge aluminium and are backed by 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?
Metal roofs in Calgary generally cost more upfront than asphalt shingles. Actual price varies with roof size, slope, complexity (hips, valleys, dormers), tear‑off requirements, flashing, skylights and labour. Local construction factors — labour rates, permit fees, cold‑climate details and material availability — also influence cost in Calgary. Many homeowners compare roofing options by lifetime value rather than initial price: a higher upfront investment in a durable metal system often lowers long‑term repair and replacement costs, reduces maintenance and can improve resale appeal. When budgeting, get an on‑site estimate that accounts for complexity and any warranty or energy‑saving features. Consult local contractors for detailed quotes. Interlock Metal Roofing focuses on long‑term ownership value—offering durable systems designed to reduce future costs—rather than positioning itself as the lowest‑cost roofing option.
Should I choose metal roofing or asphalt shingles for my Calgary home?
Short answer: metal roofing can be worth it in Calgary if you prioritise durability and long‑term protection.
Lifespan: metal roofs typically last 40–70+ years versus 15–30 years for asphalt shingles.
Maintenance: metal usually needs less upkeep (periodic inspections, resealing fasteners) while shingles require more frequent repairs/replacement from granule loss and curling.
Durability: metal resists wind, sheds snow and tolerates freeze–thaw cycles better; Calgary’s frequent hail events and high storm risk can still damage some shingle roofs—Calgary sits in “hail alley.” Freeze–thaw cycling also stresses roofing materials in winter, accelerating shingle wear.
Long‑term value: higher upfront cost for metal often pays off via longer service life and lower lifecycle costs.
Homeowners seeking long‑term performance and architectural curb appeal often choose Interlock Metal Roofing systems for their durability, watertight interlocks and refined finishes.
Are metal roofs noisy when it rains in Calgary?
In Calgary, AB, this is a common myth: modern residential metal roofs installed over solid decking do not sound like barn roofs. A typical residential metal roof sits on solid sheathing, with underlayments, insulation and attic airspace that all reduce rain noise. Insulation, attic space and the complete roof assembly affect how sound is transmitted; a poorly insulated or improperly installed roof will be louder regardless of material. Installation quality—secure fastening, correct underlay and ventilation—matters. Properly installed residential metal roofs are typically similar in sound to asphalt shingle, tile or cedar roofs during rainfall. Interlock Metal Roofing systems are supplied and installed as complete roofing systems specifically engineered for residential homes, with components chosen to control noise and performance.
How energy-efficient are metal roofs in Calgary?
Yes — metal roofing can be energy efficient in Calgary. High‑reflectance metal finishes reflect sunlight, lowering summer cooling loads, while cool‑colour coatings can further reduce solar heat gain. However, overall performance depends on the roof assembly: insulation levels, air sealing and ventilation strongly influence heating demand in Calgary’s cold winters and control condensation and ice‑dam risk. Climate matters too — because Calgary has long, cold heating seasons and warm sunny summers, the annual energy benefit from reflectivity is seasonal and depends on your home’s insulation and usage. Homeowners replacing roofs often weigh energy efficiency to lower utility bills, improve indoor comfort, limit moisture problems and add long‑term 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’s location in Alberta’s “hail alley” means frequent large hail, strong gusts and intense convective storms that can cause severe roof damage; the city warns of hail and high wind, and Alberta has experienced repeated costly hail events. Metal roofing performs well in wind and heavy storms — it sheds water, resists uplift when properly secured, and often tolerates hail better than asphalt shingles — but actual performance depends on system design, installation quality and material durability. Key factors: system design (profile, underlayment, fastening), installation (correct fasteners, flashings and sealing) and material durability (gauge, alloy and corrosion‑resistant coatings). Homeowners consider weather resilience to lower repair/insurance costs and extend service life. Interlock Metal Roofing systems are engineered for durability, hail protection and wind resistance.
Will a metal roof rust or corrode in Calgary's wet climate?
Corrosion and rust resistance in metal roofing are vital in Calgary, AB. Performance depends on the metal—steel, galvanized steel, zinc, copper and aluminium each behave differently. Some materials, like copper and aluminium, resist corrosion better; untreated steel can rust over time, especially where water and salts concentrate. Aluminium performs particularly well in wet or coastal environments because it forms a protective oxide layer that slows degradation.
Homeowners should consider corrosion resistance to extend roof life, reduce maintenance, avoid leaks and staining, and protect property value and warranty coverage. Interlock Metal Roofing systems use aluminium construction designed for strong corrosion resistance and are protected by the Alunar Coating System for extra durability and long‑term protection.
How often should I inspect and maintain my metal roof in Calgary?
Metal roofing is generally considered a low‑maintenance, durable option for Calgary, Alberta’s climate, but no roof is completely maintenance‑free. Homeowners should inspect their metal roofs periodically—after major weather events and each season—for loose fasteners, damaged flashing, clogged gutters, and debris build-up. Leaves, branches, grit and snow/ice can trap moisture or scratch protective coatings; ice dams and wind can loosen penetrations and sealants. Check roof penetrations (vents, chimneys, skylights), seams and flashings, and clear gutters and downpipes to ensure proper drainage. Promptly remove debris and arrange repairs for dents, rust spots or failed sealant to extend service life. Regular, simple inspections and timely minor repairs keep metal roofs performing well for decades.
How does curb appeal affect my home's resale value in Calgary?
Yes—metal roofing can increase a Calgary home’s value. Local buyers often prioritise durable, low‑maintenance roofs that reduce future upkeep and insurance concerns. Premium roofing materials also boost curb appeal, making homes stand out in competitive markets. A long lifespan increases buyer confidence by lowering perceived future costs. Architectural style matters: roofs that suit a neighbourhood’s character typically add more value than styles that clash. In Calgary’s climate, metal’s resistance to snow, ice and wind is seen as an advantage, which can translate into stronger resale interest and smoother inspections during sale. 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, letting homeowners match traditional or contemporary designs while delivering performance and longevity.
Can I install solar panels on my Interlock Metal Roofing System in Calgary?
Yes. Interlock Metal Roofing Systems are compatible with solar panels when custom solar brackets installed by Interlock Metal Roofing (Alberta) Ltd. are used. Calgary roofs face heavy snow loads and freeze–thaw cycles from Chinook-driven temperature swings, plus frequent hailstorms—so choose durable, long‑lasting materials that minimise roof work after solar is mounted. Roof lifespan is important when adding solar, and homeowners should plan for future solar when replacing a roof; long‑lasting metal systems are often preferred because Interlock systems are designed to support solar mounting solutions and reduce the chance of needing roof replacement under panels.
