Interlock® Aluminum Roofing — all-climates performance specs for Blue Canyon, Washington
| 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:
Over all a good experience, but it's hard to recommend something after such a short time and people's needs are different. See above comments I think it's hard to evaluate a new roof with a lifetime warranty after a very short time and very little rain, but so far we're very happy.
Overall I didn’t have the greatest experience but that was primarily from the contracted installation crew and their lack of follow through with doing the roof right the first time. Otherwise I’m happy with the way the roof looks and the quality. And despite having to have part of it redone I appreciated the interlock rep going up in my attic and making the crew redo it correctly so I had a quality job. His honesty about the situation went a long way. I would have liked to choose when they were coming. When you’re paying upwards of 50k for a roof I would think you could have some say.
They can improve with a better communication between the installation crew and the client. If there was an Interlock member with the crew as a translator, that could have helped. The installation crew need more tarps and a magnet to pick up the remaining debris of nails. There was asphalt dust all over the yard. I believe it will be a good roof.
Just a few days ago my husband and I were excited to see our new Interlock aluminum roof completed in the gorgeous eye popping finish of copper penny shake topping our newly purchased log home in Bellingham WA. We are so thankful for the signage that the company uses when completing new roofs because when we were first looking at our home and considering a purchase we happened to drive by a house just down the road that had the same " title="copper" data-wpil-keyword-link="linked">copper finish aluminum Interlock roof that we eventually decided on. Seeing this roof installed on another house was the impetus that we needed to call the company and begin our inquiry well before we even purchased our home. We did our homework and considered other roofing materials and companies, but Interlock stood out in our minds as our top choice. The Interlock salesmen, Ross and Paul also went out of their way to come and look at the home and the roofing and bring samples to put on the roof for us to see during our inspection period. They also met with us immediately after closing on a Sunday as we wanted to lock in on a date for installation as soon as we could. We have a very large square footage of roofing, as well as a roof line that is very prominent on the house and we wanted to do something to enhance the stately character for what is definitely a very magical house and property. We have only now owned our house for less than two months, and already have our beautiful new roof completely installed. As we closed on our house in mid-October and we live in the Pacific NW near the Canadian border, this is already a feat. The team of roofers who were sent by Interlock to do our installation were some of the hardest working, most focused, and skilled labor crew we have had the pleasure of coming across. They completed the job in 2.5 weeks, working weekdays and Saturdays, arriving at 7:30 AM and working until 6 PM into the darkness with headlamps on. They worked in rain, cold, and very windy conditions, removing 90,000 lbs. of clay " data-wpil-keyword-link="linked">tile roofing and replacing it with the Interlock 100 year warrantied high quality roofing. The team was extremely respectful, also replacing a skylight that we added to the job mid-way and reinforcing roofing around other skylights that appeared to be leaking. All members of the Interlock company that we have spoken with or had contact with otherwise have been friendly and personable, respectful, and quickly and effectively addressed any questions or issues that we have brought to their attention. We feel safe and secure under our beautiful and functional Interlock roof that is quiet when it rains and lets the water run off in rivulets into the eaves. We thank everyone at Interlock and hope to have a long and successful relationship with Interlock and our new roof.
Correcting the one error quickly. i would like to suggest they look into a better way to do the nailing. The nails are popping through under our roof and it doesn't look very nice. Otherwise we love our roof.
Paul is a great guy. The biggest disappointment is that we couldn't go with Paul.
Not for existing properties. If new construction yes. I have several siblings living in this town in over million dollar homes and they have heard my frustrations. First change the wording in your acceptance letter from available 24-7 availability to Monday through Friday time zone available.Making sure someone has on-call contact for emergencies (leaking roof).Being able to return calls, scheduled dates. Initial sales pitch should match what is on line with regards to the actual warranty-false sales pitch really is a sticker to us. The crew really should take consideration of laying the tarps (I saw but never used)-could prevent leaking roof. Also I have a cover on my garage that would be very expensive to replace had their metal pieces hit it is such a way as to put tears in it. I noted several things fall from roof onto this covering.
Communication, follow up, status checks, etc. I received a confirmation of final payment about a month later and still have not received warranty documents. ( as of March 1st) Final check written on January 22. Job finished on Jan 16.We also could have benefitted from better information and consultation/education on snow guards. In February we received a lot of snow. The snow sliding off our roof on the north side and dropping onto a second story deck has really caused us some concern. It was 22" deep and had t be shoveled off. I am not sure about what to do in the future and if this is a hazard or if damage will occur to the deck structure. During the initial presentation / ordering Paul asked if we wanted snow guards, but no advice or more in-depth consideration was given pertaining to the design of our residence. We do not get a lot of snow each year, but it should be considered more carefully. We also did not care for the "buy it right now to get the best price" approach. You should drop this high pressure sales technique and your company would benefit - it can cause some trust issues with customers. Hoping to hear back about what we might consider regarding snow issues.
My only suggestion would be to recycle the cardboard packing if possible.
I had a hard time remembering their name. I love my new roof.
See above. Thank you to everyone who helped us throughout this process!

Metal Roofing FAQs for Homeowners in Blue Canyon
The following metal roofing FAQs are designed specifically for homeowners in Blue Canyon, Washington. 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 Blue Canyon.
How does a metal roof handle Blue Canyon's heavy snow and freeze-thaw cycles?
Aluminum's smooth, hard surface sheds snow more readily than asphalt, reducing ice dam formation during Blue Canyon's typical 43 cm annual snowfall and 47 freeze-thaw days. The four-way interlocking panels are warranted to 120 mph wind resistance, so they hold firm when snow and ice shift. Because the material itself never rots or splits—unlike wood or slate—it tolerates repeated freeze-thaw stress that degrades other roofs. Snow guards are available if you want to control shedding.
Does an Interlock metal roof leak in heavy rain like Blue Canyon gets?
No. Interlock's four-way interlocking design sheds water continuously, and the panels are installed over solid deck and underlayment—the same watertight foundation as asphalt. Blue Canyon averages about 1312 mm of annual rainfall; the overlap geometry and slope work together to move water off before it can pool. The ICC-ES evaluation (ESR-1790) certifies the system for both wind and water intrusion under code-standard testing. Leaks are a fastener or flashing error, not a material failure.
Why does aluminum stay durable through freeze-thaw cycles better than other roofing?
Aluminum has no internal structure that absorbs moisture or expands when frozen. It flexes slightly under stress, so it doesn't crack or curl the way asphalt, wood, or clay do. Blue Canyon's 47 annual freeze-thaw days test materials hard; wood shakes split, asphalt loses granules and curls, and concrete tile cracks. Aluminum's oxide layer also self-heals when scratched, so micro-damage doesn't become a failure point. The Guardian Warranty explicitly covers splitting, cracking, and curling—conditions that aluminum simply doesn't develop.
Can an aluminum roof rust in Washington's wet, rainy climate?
Aluminum cannot rust because it contains no iron. Instead, it forms a thin, invisible oxide layer that naturally protects the metal beneath; if scratched, the oxide re-forms automatically. This matters in Whatcom County's wet climate: steel roofing corrodes in salt air and rain, but aluminum stays intact. The Alunar 70% PVDF coating—applied to both sides of every panel—adds 30 years of fade and chalk protection (ASTM D4214/D2244 certified). Together, the metal and coating create a corrosion-resistant system that lasts decades without degradation.
Will a metal roof survive Blue Canyon's coastal wind gusts?
Yes. Interlock panels resist wind speeds up to 120 mph when installed to specification, and Blue Canyon's typical gusts reach about 100 km/h (62 mph)—well within that margin. The four-way interlocking system locks each panel to its neighbors, distributing wind load across the entire roof rather than stressing individual fasteners. Coastal and mountain installations from BC to the Antarctic have proven this design. The warranty covers wind resistance at 120 mph; you're protected against the weather your region actually delivers.
Do I need to reinforce my home's structure for a metal roof?
No. The Slate profile installs at 0.41 lb/sq ft and the Mediterranean Tile at 0.59 lb/sq ft—about 96% lighter than concrete or clay tile. Most homes can support Interlock panels over the existing roof without any structural work. This matters in Blue Canyon because you avoid costly framing upgrades and can install over asphalt, wood, or other materials, saving on tear-off labor and landfill fees. The lightweight design also means less burden on aging structures, reducing settlement risk over the 50+ year service life.
What hail rating does Interlock have, and will it lower my insurance?
Interlock achieves UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. Class 4 often qualifies for insurance discounts because it demonstrates resilience to the most severe hail events. Contact your insurer with the UL rating and warranty details; many carriers reduce premiums for Class 4 roofs. In Whatcom County, severe hail is less frequent than heavy rain, but the Class 4 rating gives you peace of mind and a potential bottom-line benefit.
What does the lifetime warranty really cover, and how long will the roof last?
The Guardian Warranty is a non-prorated, lifetime limited material warranty for the original owner and covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's transferable once, giving the next owner 50 years from completion—a real asset at resale. Interlock has been manufacturing since 1998, so roofs installed in the late 1990s are still in service. In Blue Canyon's 1312 mm annual rain and 43 cm snow, the sealed, corrosion-proof aluminum system is engineered to outlast asphalt (15–20 years) by decades. This is the last roof you'll install.
How much maintenance does a metal roof need versus asphalt or wood?
Interlock requires little to no maintenance—no granule replacement, no moss treatment, no wood staining. Asphalt sheds granules in Blue Canyon's rain and UV, wood absorbs moisture and rots, and tile cracks. Aluminum doesn't degrade from water or weather. Occasional gutter cleaning and visual inspection are standard for any roof. The CALGreen-verified material is recognized for reduced maintenance liability. You trade the annual upkeep of asphalt or wood for zero material degradation and a 50-year peaceof mind.
Is metal roofing actually more sustainable than asphalt shingles?
Yes. Interlock aluminum is approximately 95% recyclable at end of life, versus asphalt shingles that pile into landfills by the million tons. Because metal roofs last 50+ years instead of 15–20, you install fewer times in a lifetime, eliminating repeated tear-offs, transportation, and waste. The 1312 mm annual rainfall in Blue Canyon accelerates asphalt degradation, meaning more frequent replacement cycles. Aluminum breaks that cycle—one installation, one recycling event decades later, zero accumulated landfill burden. The material's durability is itself the sustainability advantage.
