Delta, BC Metal Roofing Review: Interlock Aluminum Shakes Gave Us the Best-Looking Roof on the Street
Delta, BC
Rick S.
We recently had our cedar shake roof replaced with aluminum shakes by Interlock. We are the first house in our strata to go to this type of roof. Interlock did a great job, in a timely manner, and we have had many comments from neighbours saying we now have the best roof on the street.

Top 10 Metal Roofing FAQs for Homeowners in Delta
Homeowners researching metal roofing in Delta 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 Delta 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 Delta, BC?
Metal roofs commonly last 40–70+ years, while asphalt shingles typically last 15–30 years. Delta has a mild, maritime climate with year‑round rainfall (wettest in late autumn) and frequent coastal moisture, which raises humidity and encourages moss and organic buildup on roofs. Being on the Fraser Lowland and near the Salish Sea also brings salt‑laden air and periodic strong winds that can accelerate corrosion and stress roof seams. These local factors make durable, corrosion‑resistant roofing attractive: metal resists rot and moss, handles wind better than many asphalt systems, and avoids repeated replacement after heavy wet seasons. Interlock Metal Roofing systems use heavy‑gauge aluminium and come with a lifetime limited 50‑year transferable warranty designed for long‑term protection in coastal, wet climates.
How much does it cost to install a metal roof in Delta, BC?
In Delta, BC, a metal roof typically carries a higher upfront cost than asphalt shingles, but many homeowners find the lifetime value outweighs the initial price. Actual cost varies with roof size, slope and complexity, whether an old roof must be torn off, plus flashing, skylights and labour. Local construction factors—labour rates, permit requirements and seasonal access in the Metro Vancouver area—can also influence pricing. Because metal systems are more durable and low‑maintenance, they often reduce future repair and replacement costs over decades, which many Delta homeowners factor into comparisons. Rather than competing as the lowest‑cost option, Interlock Metal Roofing focuses on long‑term ownership value: quality materials, professional installation and warranty-backed performance to lower total costs over the roof’s lifetime.
Should I choose metal roofing or asphalt shingles for my Delta home?
In Delta, BC, heavy year‑round rainfall and high humidity encourage moss/algae growth and persistent moisture on roofs, increasing maintenance needs for porous materials. Winters are mild with less snow than inland but variable freeze–thaw events are possible and climate projections show changing winter precipitation patterns—factors that affect roof ageing and water ingress risk.
Lifespan: metal typically lasts 40–70+ years; asphalt shingles about 15–25 years. Maintenance: metal needs less cleaning and resists moss; shingles need periodic clearing, moss/algae treatment and replacement. Durability: metal withstands wind, moisture and rot better; shingles are more vulnerable to granule loss, lifting and freeze–thaw damage. Long‑term value: metal’s higher upfront cost is offset by longer life, lower maintenance and better resale for homeowners prioritizing durability and long‑term protection. Metal isn’t right for everyone, but those seeking lasting performance often choose it. Interlock Metal Roofing appeals for its longevity, watertight design and architectural curb appeal.
Are metal roofs noisy when it rains in Delta?
Are metal roofs noisy when it rains in Delta, BC? This is a common myth. Modern residential metal roofs installed over solid decking do not sound like barn roofs. Sound depends on the whole roof assembly: insulation, attic space, underlayment and fastening method all reduce noise. A well‑insulated attic and proper underlayments make rain on metal comparable to asphalt shingles or tile in perceived sound. Installation quality matters—secure fastening, solid decking and continuous underlayment prevent flapping or amplified noise. Properly installed residential metal roofs are typically similar in sound to other roofing materials. Interlock Metal Roofing systems are installed as complete roofing systems designed for residential homes, with components chosen to control weather and sound.
How energy-efficient are metal roofs in Delta?
Metal roofs can be energy efficient in Delta, BC. Their reflective finishes reduce solar heat gain in summer, lowering cooling loads, while cool-colour coatings can boost that effect. Overall energy performance also depends on the roof assembly—underlayments, insulation levels and ventilation—because these control heat transfer and moisture management year‑round. Delta’s temperate, maritime climate—warm summers and cool, wet winters—means reflection helps in summer, but adequate insulation and ventilation are critical for winter comfort and to prevent condensation. Homeowners consider energy efficiency during roof replacement to lower utility bills, improve indoor comfort, extend roof and HVAC lifespan, meet building codes or incentive programs, and increase resale value. Interlock Metal Roofing systems are designed to support long‑term home performance.
How does metal roofing in Delta, BC withstand wind, hail, and severe weather?
Delta, BC lies in the coastal Lower Mainland and faces frequent heavy rain, seasonal southwest winds with gusts to about 50 km/h, and periodic convective storms that can bring intense downpours and localized hail—conditions that stress roofs and flashing systems.
Metal roofing can perform very well: properly engineered seams and fastenings resist wind uplift and shed water, thicker gauges or impact‑rated profiles limit hail damage, and non‑combustible metal tolerates heavy storms better than many asphalt systems. Performance depends on roofing system design, installation quality and material durability. Homeowners weigh weather resilience to protect structure, reduce repairs and manage insurance exposure. Interlock Metal Roofing systems are engineered specifically for durability, hail protection and wind resistance, but benefits require correct design and professional installation.
Will a metal roof rust or corrode in Delta's wet climate?
Metal roofing performance depends on the metal chosen—steel, zinc, copper and aluminium all behave differently. Some materials form protective layers or resist oxidation better, so they are inherently more corrosion‑resistant. Aluminium performs particularly well in wet or coastal environments because it naturally forms a protective oxide layer and resists salt‑air attack. Homeowners should prioritise corrosion resistance to maximise roof longevity, reduce maintenance and repair costs, preserve warranties and avoid leaks, staining and structural deterioration. Interlock Metal Roofing systems use aluminium construction designed for strong corrosion resistance. Interlock Metal Roofing Systems are protected by the Alunar Coating System for extra protection, providing an additional barrier against moisture and atmospheric contaminants and helping maintain appearance and performance in Delta’s coastal climate.
How often should I inspect and maintain my metal roof in Delta?
Metal roofing in Delta, British Columbia is a durable, low‑maintenance option for local homes. While metal roofs require less upkeep than many materials, no roof is completely maintenance‑free. Homeowners should inspect roofs periodically—at least annually and after major weather events—to catch problems early. Check for accumulated debris, clear gutters and downspouts, examine flashing around chimneys, vents and skylights, and inspect penetrations, fasteners and sealants for corrosion or loosening. Seasonal debris (leaves, branches) and coastal or storm‑related weather can accelerate wear or block drainage, so remove obstructions promptly. With routine checks and occasional minor repairs, metal roofing provides long service life and reliable protection with relatively low ongoing labour and expense.
How does curb appeal affect my home's resale value in Delta?
In Delta, BC, metal roofing can increase home value. Buyers value durable, low‑maintenance roofs, and premium roofing materials boost curb appeal. The long lifespan of metal roofing also improves buyer confidence, reducing perceived future costs. That said, architectural style matters in neighbourhoods: a roof that complements local character is more likely to add value. 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, letting you match aesthetic and performance priorities. Consider matching finish and colour to neighbouring homes to maximise value.
Can I install solar panels on my Interlock Metal Roofing System in Delta?
Yes — Interlock Metal Roofing Systems in Delta can accept solar panels when fitted with custom solar brackets installed by Interlock Metal Roofing (BC) Ltd. Their custom brackets are installed for metal profiles to maintain watertight seams. Delta’s coastal, high‑rainfall conditions and periodic strong winds increase moisture, salt exposure and wind loads on mounts, so corrosion‑resistant and wind‑rated attachments are essential. Roof lifespan matters when adding panels — choose long‑lasting materials now if you plan future solar. Interlock systems are solar‑compatible and engineered to support mounting solutions; ask about flashing, warranty impacts and corrosion‑resistant finishes for Delta’s salt air and moisture.
