Interlock® Aluminum Roofing — all-climates performance specs for Chilliwack, BC:
| Spec / Rating | Climate / Risk Factor + What It Solves |
|---|---|
| Wind resistance: 120+ mph (193+ kph) | Extreme wind, hurricanes, storm uplift: full interlocking attachment helps prevent blow-offs, edge lifting, and panel loss in high-gust events. |
| Fire rating: Class A (with proper assembly) | Wildfire, embers, radiant heat, chimney sparks: non-combustible roof assembly provides the highest residential fire protection rating. |
| Hail resistance: UL 2218 Class 4 | Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes. |
| Snow & ice performance: interlocking, shedding profile | Heavy snow, freeze-thaw, ice dams: smooth aluminum sheds snow efficiently and the interlocking design helps block water intrusion when melt-refreeze cycles occur. (Final snow-load capacity depends on roof structure and local code.) |
| Corrosion resistance: aluminum (won’t rust) | Salt air, coastal humidity, wet climates: aluminum naturally resists rust and corrosion, reducing long-term failure risk in marine or high-moisture environments. |
| Heat / UV durability: baked-on coating system | High heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation. |
| Moss / algae resistance: smooth coated surface | Wet shade, organic growth: low-porosity metal surface gives moss/algae less to grip, reducing staining and maintenance. |
| Material: heavy-gauge aluminum roof profiles (Slate / Shake / Shingle / Tile / Standing Seam) | All-season structural stability: lightweight, dent-resistant metal system stays stable through large hot-cold swings and severe weather. (Add exact alloy + thickness for maximum spec proof.) |
| Expected lifespan: 50+ years | Long-term durability across climates: avoids re-roof cycles typical of shorter-life materials, even in high-stress environments. |
| Warranty: Lifetime-Limited, non-prorated + 50-year transferable | Lifetime protection + resale value: guarantees long-term material confidence and transfers to future owners. |

FAQ's for Chilliwack, BC by Interlock Metal Roofing (BC) Ltd.
-
In Chilliwack, we see a lot of roofs that look tired but are still repairable — and others that fail fast because water has been getting in for years. With our long, wet seasons and heavy fall debris from nearby trees and mountains, small leaks or lifted shingles can quietly turn into rotten decking and mold. Generally, if the issue is isolated (a small leak, a few missing shingles, flashing damage), a repair can buy real time. But if you’re seeing recurring leaks, soft spots, widespread granule loss, or sagging areas, replacement is usually the smarter, cheaper long-term move. A solid roof here isn’t just about stopping rain today — it’s about keeping your insulation dry, your attic healthier, and your heating bills steady through damp winters. If you want a clear answer for your home in Chilliwack, we can take a look and give you options.

For most single-family homes in Chilliwack, a full roof replacement typically ranges widely depending on material and complexity. As a rough local ballpark: asphalt shingle roofs often land in the mid-$10k to $20k+ range, while metal roofing systems are usually higher upfront but last much longer. The spread is big because every roof is different. What moves the price most here: roof size and pitch, number of valleys/dormers/skylights, how many layers need removal, and whether the plywood deck has moisture damage from Chilliwack’s rainy seasons. We always frame cost around certainty and peace of mind: paying a bit more for the right system and ventilation can prevent repeat leaks, interior repairs, and energy loss.

Chilliwack is in the Fraser Valley, which means lots of moisture, mild but wet winters, and warm summers — a perfect recipe for moss, algae, and slow water wear.  Asphalt shingles are common because they’re affordable and easy to install, but they need good airflow and maintenance here to avoid early aging and moss damage. Metal roofing performs extremely well in this climate because it sheds water fast, doesn’t absorb moisture, and resists moss growth. Cedar looks beautiful but can struggle in damp zones without consistent care. The “best” material is the one that gives you the fewest headaches over the next 20–50 years — not just the lowest bid today.

Yes — and Chilliwack is actually one of the places where metal shines. With heavy rainfall and frequent storm cycles, metal’s ability to shed water quickly is crucial. It reduces the chance of water backing up under roofing the way it can on slower-draining materials. We also get periodic windstorms coming through the valley and occasional snow/ice events. A properly fastened metal roof is highly wind-resistant, and the smooth surface helps snow slide off before heavy loads build up. BC roofs are designed with snow/rain loads in mind, and good metal systems work within those requirements.  Homeowners choose metal here for the same reason they choose a good truck in the Valley: reliability in ugly weather.

Ventilation is huge in Chilliwack. Our air stays damp for long stretches, and without steady attic airflow, moisture gets trapped above your insulation. That leads to mold, wood decay, and heat loss — even if the roof surface still looks okay. Proper ventilation helps your roof last longer and keeps indoor comfort stable. In winter, it reduces condensation and the risk of ice-dam style backup during freeze-thaw snaps. In summer, it helps dump attic heat so your home doesn’t bake upstairs. Think of it like a bathroom fan for your whole house: if it can’t breathe, things get gross and expensive.

Top of the list is moss and algae. The Valley’s moisture and shade from evergreens make roofs a prime growing surface, especially on north-facing slopes. Moss can lift shingles and hold water against the roof, shortening life fast. We also see flashing failures around chimneys, skylights, and valleys, because those spots take the brunt of constant rain. And in older neighborhoods, soft decking from long-term leaks is pretty common. The good news: catching these early protects your home’s structure and keeps repairs small.

Local lifespan is heavily affected by moisture. In general around Chilliwack: • Asphalt shingles: often 15–25 years depending on ventilation and moss control. • Cedar shakes: can reach ~25 years with real maintenance, but damp conditions are tough on them.  • Metal roofing: commonly 40–70+ years when installed correctly, because it doesn’t rot, crack, or feed moss. A roof’s “real” lifespan here is about how dry and ventilated the system stays — not just the product label.

In Chilliwack and the Fraser Valley, permits are typically required for major renovations and especially if you’re changing roof type or doing structural fixes. The City and Regional District both point homeowners to their building permit process under the BC Building Code. Timeline-wise, once permits are in place, most residential tear-off and re-roof jobs take a few days to about a week, depending on size, weather, and roof complexity. Rain delays are normal here, so we plan around them. Permits aren’t just red tape — they help ensure the roof is safe for snow/rain loads and properly ventilated for our climate.

After a big Fraser Valley storm, the first thing is a safe visual check: look for missing shingles/panels, lifted edges, debris impact, or new staining in your attic or ceilings. Wind-driven rain can sneak in through tiny openings, so new interior spots matter. If there’s damage, document it early with photos and dates. Insurance typically covers sudden storm damage, but not long-term wear or moss-related decay. The clearer the “before vs after,” the smoother your claim usually goes. We often help homeowners by giving a straightforward condition report and repair/replace options they can share with their insurer.

A good Chilliwack roofing contractor should talk as much about ventilation, moisture control, and detailing as they do about materials. Our climate punishes shortcuts — so you want someone who explains the “why,” not just the price. Green flags: clear written estimates, local references, proof of insurance, and a plan for weather delays. Red flags: pressure to sign same-day, vague warranties, skipping attic review, or refusing to discuss decking condition. The right contractor gives you confidence that this job won’t be back on your to-do list in five years.
