Interlock® Aluminum Roofing — all-climates performance specs for Kamilche, 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. |

What our customers are saying:
Thanks for a very positive roofing experience! Our new roof is so beautiful we’re thinking of charging a fee to all the gawking neighbors that stop by to admire it!!! This was fun, positive experience from start to finish. Our sales rep spent three hours at our home going over every possible detail with us. He was knowledgeable, friendly and answered all our questions. As you can see by the pictures we have a pretty basic roof. There was no tear off to do; still, our three installers were 80% done on the very first day! Everything was done and cleaned up to our satisfaction by the end of day two. Our installers were friendly, courteous and hard working. I watched them for a few minutes as they all worked like a finely tuned machine installing our roof in perfect rhythm. For us, Interlock meant that the third time was the charm. We’d tried to do business with two other companies. The first took a large amount of money as a down payment and gave absolutely no customer service for two months. We got our money back and started over. The second company gave an inaccurate bid. Needless to say, we entered into this contract with some trepidation. interlock is a fabulous company and we’d recommend them to anyone in the market for a new roof!
We are writing this letter to show our appreciation for the wonderful job that was done on our roof. From the date your company representative met with us in our home to the date of completion, words cannot express how completely satisfied we are with your company. We definitely wanted a quality roof and were very impressed by the representation that was given to us. The product you provide was enough for us to make our decision, however it was a huge plus not to have to deal with a pushy salesman and to have such polite, friendly and hard working men providing the service. It was a pleasure to have them around our home. The quality, craftsmanship and lifetime warranty of this roof far outweighs the increased costs over other roof systems. However, other roof systems don't come with lifetime warranties and many only last for 8 to 10 years. We may have paid a little more initially, but how wonderful it is to know we will never have to re-roof our home again. And in addition to all of the above, it looks so beautiful and has added so much style to our home. I never dreamed a roof could make such a difference. Again, Thank you so much and be sure to know we will highly recommend your company to all of our family and friends.
I am very pleased with the entire experience with Interlock Roofing. Ross did a fantastic job of showing me all of the options available, and explaining how Interlock is different from other roofing. This was not a hard sales pitch. I was pleasantly surprised by how affordable a metal roof was. I had five other estimates for a traditional composite roof, and the price difference for a forever roof was negligible considering all the benefits. Next, the installation. These guys were amazing! Only two guys doing the demo and reroof, but very hard workers and did a fantastic job. It seems rare these days to find skilled tradesmen that take pride in their work, and these guys exceeded my expectations. I also took advantage of Interlock’s financing. Drew was very helpful and accommodating. The whole process was taken care of through Interlock, making it super convenient and great communication throughout. I will highly recommend:)
We just wanted to let you know how thoroughly-pleased we are with our new Interlock Roof. It is absolutely beautiful and we have had a lot of people stopping as they walk or drive by to admire how nice it looks. Everything progressed on the job exactly as you had shared with us when we signed the contract. There were no surprises. From the beginning when we got the call to set up a start date, to the final clean up and retrieval of the waste bin everything was handled so professionally. Viktor and Alex were a dream to work with-so-pleasant and each day everything was left so tidy that it would have been hard for guests to tell that we were in the middle of a re-roofing job. We will highly recommend your product and doing business with such a professional and obviously well run company.
I have already recommended them. Those guys were amazing. Peter, Victor, and the other installation guys were just unbelievable. It is a great company, and they did a great job with my roof. I get compliments all the time. It was a wonderful experience. They did a wonderful job on the house. It looks fantastic.
Interlock Roofing is amazing. From the first day I met their salesman to the day they started work on our barn and house. They were very easy to talk to and express our concern about how important it was to keep our hay safe from rain and the ground around the barn safe for the animals. They were fast exceptionally clean and so much fun to get to know. I definitely would recommend this company to anyone who wants to have a roof that will last a life time. Thank you for an amazing job and two beautiful roofs!
My wife and I want to express our complete satisfaction with the "Aged Copper" roof your firm installed on our "Barn-house" and gazebo. The two roofs have a high quality appearance and they enhance the looks of the property. We are looking forward to many years of satisfaction. We are now planning to re-paint the house with a color to better blend with the roof. The work performed by your installers was outstanding. They were friendly and very professional. They worked efficiently and energetically, and it was obvious they had the skills to do the job. Thank you for being such an excellent firm.
My husband and I would like to thank you for coming to our residence and explaining your product and all of its advantages. We were very impressed at this time and excited to start the beautification process of our home, which has been in my husband’s family for 5 generations now. It has undergone many remodels, upgrades, and changes throughout the years with a lot of help from friends and family. We will be celebrating its 100th birthday this year. The new roof is definitely a wonderful way to do so! The whole Interlock family was friendly and extremely easy to work with from the beginning of this process to the end. The job was started on time and finished when promised. We are very pleased with how smoothly the project went and very thankful that we were not the ones on top of the house!
HELLO! I am Gerry from Olympia, Washington. A few years ago, I had my re-roofing done by INTERLOCK ROOFING SYSTEM for my house here in Olympia. I would like to thank the INTERLOCK ROOFING SYSTEM for the best, beautiful metal roof I ever had; the color choice never changed in spite of the weather condition here in Washington. So, if you want your home to deserving a thorough, keen, professional touch, quality, and professionalism, I would highly recommend INTERLOCK LIFETIME ROOFING SYSTEMS for your COMPLETE METAL ROOFING.
We both work for Nordstrom and have come to expect a certain level of customer service. Both Paul and Ross were exceptional in this regard. They were knowledgeable friendly and very thorough! I would highly recommend interlock for anyone looking into metal roof options.
The roof is absolutely beautiful and compliments our home. The work was fast and professional. Communication about scheduling. Clean up of job site. We absolutely love the roof.
We were extremely pleased with Interlock Roofing as our selection to install an aluminum roof on our house and two outbuildings. The installation team were extremely hard workers and were always courteous and conscientious and left our project very clean. We would highly recommend all of them to anyone interested in a new roof including Paul Wright and the administration staff. Ron and Joanne Quiring nothing

Metal Roofing FAQs for Homeowners in Kamilche
The following metal roofing FAQs are designed specifically for homeowners in Kamilche, 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 Kamilche.
How does a metal roof handle heavy snow in Kamilche?
Metal roofs shed snow and ice efficiently because the smooth, hard surface prevents buildup that occurs on asphalt. Kamilche receives about 40 cm of snow annually across roughly 34 freeze-thaw cycles, which creates the exact conditions where ice dams destroy standard shingles—the freeze-thaw flexing cracks them. Interlock's four-way interlocking aluminum panels stay rigid through temperature swings, and snow slides safely off without pooling. You can add optional snow guards if you want controlled release. The lightweight design means no structural upgrade needed, even in a bad year.
Why won't my aluminum roof rust like steel roofs do?
Aluminum physically cannot rust because it contains no iron—iron is what oxidizes and turns to rust. Instead, aluminum forms a thin, invisible oxide layer that actually protects the metal underneath and heals itself when scratched. On top of that, every Interlock panel gets Alunar 70% PVDF fluorocarbon coating on both sides, warranted 30 years against chalking and fading. In Kamilche's damp marine climate with 1370 mm of annual rain, that dual protection is serious insurance. Steel roofs corrode from the inside out in this environment; aluminum just gets tougher with age.
Do I need to reinforce my house to support a metal roof?
No structural reinforcement required. Interlock's aluminum Mediterranean Tile profile weighs only about 0.59 lb per square foot—roughly 96% lighter than actual concrete or clay tile. For comparison, asphalt shingles run 2–3 lb/sq ft, so metal actually reduces load on your framing. This matters in Kamilche where older homes have standard rafters designed decades ago. You can install metal roofing directly over most existing roofs without tearing anything off, which saves thousands and keeps debris out of landfills. The light weight is a hidden engineering advantage most homeowners don't realize they're getting.
What does the warranty actually cover and for how long?
The Guardian is a lifetime limited, non-prorated material warranty for the original owner—it covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance. That means no gradual reduction of coverage as the roof ages. It's transferable once, giving the next owner 50 years of protection from the completion date. Most homeowners keep a house 20–30 years, so this warranty outlives your ownership by decades. Combined with Interlock's track record since 1998 and local installation by the PNW team since 1997, you're betting on aluminum that's proven itself from coastal salt-air homes to Antarctic research stations.
Will my metal roof hold up in Kamilche's wind and storm gusts?
Yes. Interlock panels are warranted to resist wind speeds up to 120 mph when installed to spec, and Kamilche's typical wind gusts max out around 99 km/h (about 62 mph)—well within that range. The four-way interlocking design means each panel locks to its neighbors on all sides, creating a unified system that flexes and holds rather than peeling up. Heavy annual rainfall of 1370 mm comes with Pacific storms, but the seams are designed to shed water, not trap it. Insurance companies often offer discounts for metal roofs because underwriters trust the engineering and wind-test data.
Is a metal roof fire-resistant in a wildfire zone?
Interlock aluminum is non-combustible—it won't ignite, burn, or emit smoke. Class A fire-rating versions are available and comply with ICC-ES evaluation report ESR-1790 (reissued 2025), which covers the latest building and fire codes. In Kamilche and the broader Pacific Northwest, wildfire risk is a real consideration even in residential areas. A non-combustible roof eliminates one major point of failure during an approaching fire; embers can land on metal without starting a fire. Check your homeowners insurance policy—some carriers reduce premiums for Class A ratings because the risk profile is genuinely different.
Can a metal roof actually save money on cooling costs?
Metal roofs with reflective coatings reduce the heat your roof absorbs, lowering cooling demand. Interlock's energy-efficient colors achieve initial solar reflectance up to 0.55 and thermal emissivity of 0.84, reflecting heat that asphalt absorbs and re-radiates into your home. Kamilche gets about 2881 sunshine hours per year—enough to make reflectance meaningful. On summer days above 20°C, the difference compounds. The Cool Roof Rating Council rating confirms independent testing. In the Pacific Northwest where cooling isn't year-round, the real benefit is consistency: no hot spots, no premature shingle degradation from UV, and lower peak loads on air conditioning.
What maintenance does a metal roof actually need?
Almost none. Unlike asphalt shingles, which require periodic inspection and seal-down, or wood shake, which needs treatment and moss removal in wet climates like Kamilche's (1370 mm rain annually), metal roofing is CALGreen-verified for reduced maintenance. Gutters still need cleaning and occasional debris removal, but the roof itself doesn't degrade, curl, or crack from Kamilche's 34 annual freeze-thaw cycles. No algae or moss takes hold because aluminum is inhospitable to growth. A rinse with a garden hose every few years keeps it looking new. That's it—the lifetime warranty isn't a gimmick because there's genuinely little that breaks.
How long does metal roof installation take and do I have to remove my old roof?
Installation typically takes a few days to a couple of weeks depending on roof complexity and weather (Kamilche averages 2881 sunshine hours annually, so scheduling around rain is practical planning). Most importantly, you don't have to tear off your existing shingles. Interlock installs directly over them with a solid deck and underlayment—the same approach that keeps a metal roof quiet in heavy downpours as 1370 mm of rain falls. Avoiding tear-off saves time, labor, dumpster costs, and landfill waste. Your local installer, Interlock Metal Roofing (PNW) Inc., has been serving the region since 1997 and can walk you through timeline details and current financing: no payments or interest until Spring 2027, or 10% off installation.
Is aluminum roofing actually better for the environment than asphalt shingles?
Yes, significantly. Aluminum is about 95% recyclable, and Interlock panels never end up in a landfill—they retain value as scrap. Every time you replace asphalt shingles (typically every 15–20 years), tons of old shingles go to the dump; over a house's lifetime, that's multiple roofing landfills. A metal roof breaks the tear-off cycle entirely. Manufactured in Delta, BC since 1998, Interlock uses established recycling infrastructure. In Kamilche, where 1370 mm of annual rainfall and 34 freeze-thaw cycles hammer roofing materials, choosing aluminum instead of asphalt means fewer replacements, fewer trucks hauling debris, and a product that doesn't degrade into microplastics in groundwater.
Is a metal roof a good choice for Kamilche’s climate?
Yes. Kamilche averages about 40 cm of snow, 1370 mm of rain, roughly 34 freeze–thaw days a year, with peak wind gusts near 99 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.
