Interlock® Aluminum Roofing — all-climates performance specs for Grand Bay–Westfield, New Brunswick
| 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. |
| 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. |

What our customers are saying:
Yes I would recommend. Increased communication by the crew to the home owner regarding progress, schedule based on weather. More attention to clean up. Although our experience was not perfect, we are very very happy with our roof. It looks amazing.
I don't think there is an area that could be improved on. They were very good and very helpful. I am very pleased with the quality of the material and workmanship.
When Greg was here, we agreed upon the installation date and time. The installers did not arrive on time, but this was not a big inconvenience for me. Greg could have updated me and kept in contact with me more during the course of the installation.

Metal Roofing FAQs for Homeowners in Grand Bay–Westfield
The following metal roofing FAQs are designed specifically for homeowners in Grand Bay–Westfield, New Brunswick. Whether you are building a new home or replacing an existing roof, understanding how roofing materials perform in local weather conditions is essential. From wind and storm protection to fire resistance, hail impact, snow loads, and coastal moisture exposure, Interlock’s Lifetime Aluminum Roofing System is engineered to provide long-term durability, energy efficiency, and peace of mind in Grand Bay–Westfield.
How does a metal roof handle Grand Bay–Westfield's heavy snow and freeze-thaw cycles?
Aluminum metal roofing sheds snow effectively because its smooth, hard surface doesn't trap moisture the way asphalt absorbs it. Grand Bay–Westfield averages about 151 cm of snow annually and experiences roughly 87 freeze-thaw days per year—conditions that crack, curl, and shorten asphalt shingles. Interlock's four-way interlocking panels are ICC-ES certified (ESR-1790) and warrant wind resistance to 120 mph, meaning they stay locked through the freeze-thaw cycles and snow load stresses that plague traditional roofs. The lightweight aluminum (Shake profile at 0.58 lb/sq ft) won't accumulate ice dams the way heavy tile does, and it won't degrade from thermal cycling.
Why won't an aluminum metal roof rust in New Brunswick's wet climate?
Aluminum cannot rust because it contains no iron. Instead, it forms a transparent oxide layer that self-heals when scratched—a natural barrier that improves with age. Grand Bay–Westfield receives about 1215 mm of rain annually, but that moisture triggers no oxidation in pure aluminum. Interlock uses roofing-grade 3105-H24 aluminum alloy (ASTM B209) coated on both sides with Alunar 70% PVDF fluorocarbon finish, which carries a 30-year warranty against chalking and fading. Steel roofing, by contrast, rusts through in salt air and acidic rain; aluminum thrives in exactly these conditions, having been installed from coastal homes to an Antarctic research station.
Does metal roofing crack and deteriorate from Grand Bay–Westfield's freeze-thaw weather?
No. Aluminum expands and contracts uniformly with temperature swings—it doesn't trap water or freeze and split like wood shakes or asphalt. With 87 freeze-thaw days per year in your area, material brittleness is critical. Asphalt shingles lose flexibility below freezing and crack; slate and clay tile are inherently brittle. Interlock's aluminum panels move as a unit across the roof decking, and the four-way interlocking design distributes stress so no single panel bears the brunt of thermal cycling. The Guardian warranty explicitly covers cracking and curling—conditions that develop from freeze-thaw but are inevitable in Grand Bay–Westfield's climate.
Will a metal roof reduce insurance costs after hail damage in New Brunswick?
Some insurers offer discounts for UL 2218 Class 4 impact-rated roofing, the highest hail classification available. Interlock's aluminum panels carry Class 4 certification and are warranted against perforation from hailstones up to 1.5 inches—a durable standard that impresses underwriters. New Brunswick's climate includes wind gusts exceeding 128 km/h, and severe hail events do occur. Contact your insurer with the UL 2218 Class 4 rating and the ICC-ES evaluation (ESR-1790) to ask about premium reductions. Metal roofing's proven track record in high-impact zones often qualifies for favorable terms, especially when combined with its 120 mph wind warranty and non-combustible aluminum construction.
Can a metal roof survive Grand Bay–Westfield's coastal wind and gusts?
Yes. Interlock's four-way interlocking aluminum panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Grand Bay–Westfield experiences typical daily-max winds of about 22 km/h with gusts reaching 128 km/h—well within the system's design margin. The interlocking geometry means each panel locks on four sides to adjacent panels, preventing wind lift or separation. This differs from single-fastened asphalt shingles, which can peel and fail under sustained gusts. The lightweight construction (Cedar Shingle at 0.41 lb/sq ft) actually helps: less mass means less wind force, so the roof stays firmly locked to the deck without additional reinforcement.
Do I need to reinforce my roof frame for metal roofing in Grand Bay–Westfield?
Not with Interlock aluminum. The Mediterranean Tile profile, which replicates heavy clay or concrete tile, installs at 0.59 lb/sq ft—approximately 96% lighter than the actual materials it resembles. Real tile can weigh 10-15 lb/sq ft and require structural reinforcement; aluminum tile does not. This matters in a climate with about 151 cm of snow per year: the lighter roof distributes snow load more evenly and avoids the cumulative stress that forces structural upgrades. You can install Interlock directly over most existing roofs, saving thousands in framing work and eliminating the tear-off and disposal costs of asphalt. The ICC-ES evaluation (ESR-1790) confirms compatibility with standard residential framing.
Is a metal roof worth the higher upfront cost compared to asphalt shingles?
Interlock metal roofing costs more upfront but eliminates the 20-year cycle of asphalt tear-offs, disposal fees, and reinstallation. A typical asphalt roof lasts 15-20 years in Grand Bay–Westfield's freeze-thaw climate (87 cycles per year accelerates aging); you'll replace it 2-3 times in a 50-year period. Interlock's Guardian lifetime limited warranty covers the original owner for life and transfers once to the next owner for 50 years after completion—meaning you buy one roof that outlasts two asphalt cycles. Factor in landfill disposal ($1-3 per sq ft) and inflation on labor and materials, and the total cost of ownership heavily favors metal over that span. Current regional promotion: interest-free payments for 3 months and save at least $2499 on installation.
How much maintenance does an Interlock metal roof require in Grand Bay–Westfield?
Virtually none. Aluminum doesn't rot, split, curl, or require re-sealing the way asphalt, wood shake, and tile do. Grand Bay–Westfield's 1215 mm annual rainfall and 151 cm snow won't degrade the Alunar coating or the aluminum substrate. You won't need to clear algae, moss, or debris buildup—conditions that plague asphalt in damp climates. Asphalt requires inspection, caulk replacement, and shingle resealing every 5-10 years; tile demands mortar repointing. Interlock is CALGreen-verified for reduced maintenance. The Guardian warranty covers splitting, cracking, and curling—the maintenance headaches that define other roofs. Gutters and flashings require standard clearing; the roof itself needs no remedial work.
Is metal roofing better for the environment than asphalt shingles?
Yes, substantially. Asphalt shingles end up in landfills after 15-20 years; each roof tear-off generates 1-2 tons of waste per 1000 sq ft. Interlock's aluminum is approximately 95% recyclable and never needs replacement during your ownership or your home's next owner's 50-year transfer term. A single metal roof avoids 2-3 asphalt tear-offs and their associated transport, energy, and landfill impact. Aluminum's lightweight profile (Cedar Shingle at 0.41 lb/sq ft) means lower embodied energy in transportation. Even when eventually recycled, aluminum commands higher scrap value than asphalt, creating a real circular economy incentive. Over Grand Bay–Westfield's typical climate cycles (87 freeze-thaw days per year that destroy asphalt), one Interlock roof prevents generations of landfill accumulation.
Who installs Interlock metal roofing in Grand Bay–Westfield, and how quickly?
Maritime Metal Roofing Ltd., serving the region since 2007, is your local installer. They handle everything from inspection and design to full installation and warranty registration.

They can also advise on installing over your existing roof (often possible) to avoid tear-off costs. Contact them to schedule a site assessment and take advantage of the current interest-free 3-month payment promotion and $2499+ installation savings.
Is a metal roof a good choice for Grand Bay–Westfield’s climate?
Yes. Grand Bay–Westfield averages about 151 cm of snow, 1215 mm of rain, roughly 87 freeze–thaw days a year, with peak wind gusts near 128 km/h. Interlock® aluminum roofing is wind-rated to 193+ km/h (120 mph), UL 2218 Class 4 impact-rated and Class A fire-rated, and its four-way interlocking panels shed snow and resist ice dams and freeze–thaw cracking — all backed by a lifetime limited, transferable warranty.
