Interlock Metal Shake Roof Review — Burnaby, BC (Installed 2023)

In Burnaby a properly installed metal roof commonly lasts at least 50–75+ years, while asphalt shingles typically reach 15–30 years depending on quality and maintenance. Burnaby’s temperate, oceanic climate brings high rainfall and coastal moisture with mild winters and occasional snow—conditions that favour corrosion‑resistant, well‑drained roofing and increase the importance of good flashing and ventilation for longevity. Heavy rainfall and persistent humidity in Burnaby can promote moss growth on asphalt and accelerate wear, whereas metal sheds water, resists moss and handles wind and seasonal wetting/drying cycles with less deterioration. That durability is why homeowners often choose metal or other long‑life systems despite higher upfront cost. Interlock Metal Roofing systems use heavy‑gauge aluminium and come with a lifetime limited 50‑year transferable warranty designed for long‑term protection.

A metal roof in Burnaby will typically cost more upfront than asphalt shingles, but total cost varies widely and is best considered as lifetime value. Price depends on roof size, slope, complexity (hips, valleys, dormers), tear‑off and disposal, quality of flashing, skylights, and labour rates. Local construction factors—like Burnaby’s high annual precipitation (~1,840–1,950 mm), notable driving‑rain and moisture index, and wet Pacific snow—mean contractors must use corrosion‑resistant materials, robust flashings and underlayment, which can raise installation cost. Humid, shaded areas also promote moss growth, so metal choices and ventilation matter for long‑term performance. Many homeowners compare materials on lifetime maintenance, repair and replacement costs rather than initial price; durable metal systems often reduce future expenses. Interlock Metal Roofing positions its products and installation around long‑term ownership value rather than competing as the lowest‑cost option.

Metal roofing can be worth it in Burnaby, but it depends on priorities. Burnaby’s coastal climate brings frequent rain and persistent humidity that encourage moss/algae and prolonged roof wetting, and winters are mild with occasional freeze–thaw cycles that can stress roofing materials. Lifespan: Metal roofing lasts over 50 years; quality asphalt shingles typically last 20–30 years. Maintenance: Metal needs little upkeep and resists moss; asphalt requires periodic moss/algae cleaning and more frequent patching. Durability: Metal better resists moisture, wind and freeze–thaw damage; asphalt is more prone to granule loss and moisture-related deterioration. Long‑term value: Higher upfront cost for metal but lower life‑cycle costs and fewer replacements. Homeowners who prioritise durability and long‑term protection often choose metal. Interlock Metal Roofing systems appeal in Burnaby for their long service life, strong weather resistance and clean architectural curb appeal.

Many homeowners worry metal roofs are loud in Burnaby. That’s a common myth. Burnaby’s temperate oceanic climate brings frequent rain and coastal moisture, which also encourages moss and persistent dampness—factors that affect roof longevity and detailing. Modern residential metal roofs installed over solid decking and proper underlayment do not sound like barn roofs; their acoustic performance is governed by insulation, attic cavity, underlayment and overall roof assembly. Installation quality (tight seams, clip systems, flashings) matters. Properly installed metal roofs typically sound similar to asphalt or tile in normal rainfall. Interlock Metal Roofing systems are installed as complete residential roofing systems designed for homes in coastal BC.

Yes — a metal roof can be energy efficient in Burnaby when properly specified. Metal roofing reflects sunlight, reducing heat gain in summer, and with reflective coatings can improve performance further. However, true energy savings depend on the full roof assembly: adequate insulation, continuous air barriers and good attic ventilation are critical to control heat flow and moisture. Burnaby’s coastal, rainy climate and persistent humidity promote moss growth and prolonged roof wetness, so moisture control and ventilation matter for long‑term efficiency and roof health. Homeowners replacing roofs prioritise energy savings for lower bills, comfort and resale value. Interlock Metal Roofing systems are designed to support long‑term home performance.

As a Burnaby homeowner comparing roofing materials: metal roofing performs strongly against the region’s heavy, year‑round rain and coastal moisture and resists rot and leaks when detailed correctly; Burnaby also sees occasional wet snow and freeze–thaw cycles and persistent humidity that encourage moss growth in shaded areas. In wind and severe storms a properly designed and installed metal system sheds snow and resists uplift better than many shingles and can be specified with impact‑resistant profiles and finishes for hail protection. Performance always depends on roofing system design, installation quality and material durability. Homeowners weigh weather resilience to reduce leaks, ice‑dam and moss maintenance, and premature replacement. Interlock Metal Roofing systems are engineered for durability, hail protection and wind resistance—ask for wind ratings, impact class and correct flashing/venting to ensure peak performance.

In Burnaby’s wet, coastal climate—seasonal heavy rainfall and persistent coastal moisture—metal roofing is exposed to prolonged dampness that can accelerate corrosion if the metal or finish is poor. Metal roof performance depends on the metal: steel corrodes without good coatings, stainless steel fares better, and aluminium (aluminium) naturally resists rust in wet or coastal environments. Homeowners should prioritise corrosion resistance to avoid leaks, staining and shortened service life. Interlock Metal Roofing systems use aluminium construction designed for strong corrosion resistance and are protected by the Alunar Coating System for extra protection, making them a practical choice for Burnaby’s moist conditions.

Metal roofing is generally low‑maintenance and well‑suited to Burnaby’s coastal, wet winters and frequent rainfall, which encourage persistent moisture and moss growth. No roof is maintenance‑free: inspect at least twice yearly and after storms. Check for debris build‑up, clear gutters, and examine flashing and penetrations (vents, chimneys, skylights) for sealant wear or corrosion. Remove moss and organic debris promptly to avoid trapped moisture at seams. Metal resists rot and sheds rain well, and it handles occasional snow, but routine checks and timely repairs keep warranties valid and performance high. Compared with shingles, metal typically gives greater durability and lower ongoing upkeep in Burnaby’s climate.

Can metal roofing increase my Burnaby home's value? Yes. Buyers here value durable, low‑maintenance roofs because Burnaby’s wet, maritime climate brings heavy autumn–winter rainfall and coastal moisture that encourage moss and prolonged wetting of materials. Premium metal roofing improves curb appeal, and a long lifespan increases buyer confidence and resale value. Architectural style matters by neighbourhood—choose a profile that fits local character. Interlock Metal Roofing systems offer slate, cedar‑shingle, Mediterranean tile, shake and standing‑seam profiles in heavy‑gauge aluminium and solid copper, combining resilient performance with desirable aesthetics for Burnaby homes.

As a Burnaby homeowner comparing roofing materials, consider local factors: persistent heavy rainfall and coastal moisture—plus the region’s humidity that promotes moss growth—can affect roofing lifespan and attachment integrity. Interlock Metal Roofing Systems are compatible with solar installations when fitted with custom solar brackets installed by Interlock Metal Roofing (BC) Ltd. Roof lifespan is important when adding panels—choose long‑lasting, corrosion‑resistant materials now if you plan solar later. Interlock systems are designed to support solar mounting solutions and often simplify future panel installation; factor moisture‑related maintenance and secure bracket attachment when comparing options. Because Burnaby winters are relatively mild, freeze‑thaw damage is limited, but prolonged moisture makes proper flashing essential.
