Interlock® Aluminum Roofing — all-climates performance specs for Puget Island, 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:
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 Puget Island
The following metal roofing FAQs are designed specifically for homeowners in Puget Island, 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 Puget Island.
How does a metal roof handle heavy snow and ice in Puget Island winters?
Aluminum metal roofing sheds snow and ice far better than asphalt because its smooth, hard surface won't hold moisture the way porous shingles do. With about 55 cm of snow annually and roughly 22 freeze-thaw days per year here, that cycle is brutal on asphalt but irrelevant to aluminum—it simply has no material to degrade or curl. The four-way interlocking panels lock together so tightly that wind-driven snow and ice infiltration are blocked at the seams. Optional snow guards can be installed if you want to control where snow slides off.
With nearly 1,800 mm of rain per year on Puget Island, how do you prevent leaks?
The four-way interlocking aluminum panels overlap and lock downward and sideways, forcing water to travel away from gaps rather than into them. Over 1,800 mm of annual rainfall, that overlap design beats traditional roofing because water has no flat joint to exploit—it's mechanically directed off the roof the moment it lands. Installed over solid decking with underlayment (as code requires under ESR-1790), the system is sealed and tested. The lightweight panels install quickly and correctly, reducing on-site variables that cause leaks in heavier materials.
Why is aluminum roofing better than steel for the Pacific Northwest salt air?
Aluminum cannot rust because it contains no iron—rust is iron oxide, and aluminum oxide is a hard, transparent layer that forms on the surface and actually protects what's underneath. When that oxide coating scratches, it self-heals in hours. Salt-air coastal homes and an Antarctic research station have run Interlock panels since 1998 without rust formation. On Puget Island, where salt spray from winter wind and damp air could corrode steel roofing, aluminum's non-corrosive nature means you avoid the replacement cycle steel demands in 15-20 years.
Do metal roofs blow off in the windy Puget Sound region?
Interlock's four-way interlocking panels are warranted to resist sustained wind up to 120 mph (193 km/h), and Puget Island's typical wind gusts top out around 97 km/h—well within that limit. The interlocking mechanism works like a puzzle where each panel's edges hook into its neighbors both horizontally and vertically, so uplift force has to overcome multiple mechanical connections at once. UL 2218 Class 4 impact rating confirms the panels' structural integrity under extreme stress. Wind alone won't compromise the roof; installation to spec is what matters.
Can my house support a metal tile roof without expensive reinforcement?
Yes. The Interlock Tile profile weighs about 0.59 lb per square foot—roughly 96% lighter than concrete or clay tile. That means an Interlock Tile roof covering 2,000 square feet adds about 1,180 pounds total load, while real tile adds roughly 30,000 pounds. No structural engineer sign-off, no rafter reinforcement, no expensive engineering reports needed. Most homes in Puget Island can handle it immediately because the load is comparable to asphalt shingles. You install over your existing roof and skip the tear-off, saving time and landfill impact.
What's the real lifespan of a metal roof, and what does the warranty actually cover?
Interlock's Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner—covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It transfers once to the next owner for 50 years from completion. That's different from asphalt's 15-25 year life and most warranties that prorate or require upkeep clauses. Panels manufactured since 1998 are still in service across climates far harsher than Puget Island's 11°C average. The 30-year coating warranty (Alunar PVDF, ASTM D4214/D2244) covers chalking and fading separately.
How much maintenance does a metal roof really need?
Almost none. Unlike asphalt shingles that curl and granulate in rain and sun, or wood shake that splits and rots (Puget Island averages 1,805 mm of rain—ideal conditions for wood decay), aluminum roofing doesn't degrade from weather exposure. No sealant reapplication, no moss treatment sprays, no annual inspections for damage. The Alunar PVDF finish on both panel sides resists chalking and fading over 30 years. Occasional gutter cleaning and debris removal is normal roof maintenance for any system. That low-maintenance reality is why CALGreen lists Interlock as verified for reduced upkeep.
Is a metal roof safe if a wildfire comes through?
Interlock aluminum roofing is non-combustible—it will not ignite, spread flame, or contribute fuel to a fire. Class A fire classification is available (the highest rating). That matters in the Pacific Northwest where forest conditions can shift quickly. The material itself is inert; fire hazard comes from debris accumulation in gutters or under eaves, not the roof panel. Your homeowner's insurance company recognizes this. ICC-ES evaluation ESR-1790 confirms the fire rating under IBC/IRC codes. Combined with its lightweight strength, a metal roof gives you one less wildfire vulnerability compared to asphalt or wood.
How is a metal roof better for the environment than asphalt shingles?
Aluminum roofing breaks the asphalt cycle where shingles are torn off every 20 years and dumped in landfills. Interlock panels are approximately 95% recyclable at end of life—decades from now—and the material has value as scrap. Over a 50-year lifespan on Puget Island (roughly 90,000 mm of rainfall and natural weathering), one metal roof eliminates multiple asphalt tear-off events. Since 1998, the manufacturer has been reducing waste in production. When your roof is finally recycled, aluminum becomes part of the closed-loop economy instead of environmental liability.
How long does it take to install a metal roof, and do I have to tear off the old one?
Installation timeline typically runs 5-10 business days depending on roof size and weather. Because Interlock panels weigh so little (the Slate profile at 0.41 lb/sq ft), you install directly over your existing roof in most cases—no costly tear-off, no dumpster rental, no disposal fees. The lightweight material also means fewer crew members are needed and less strain on your home during installation. Interlock Metal Roofing (PNW) Inc. has served this region since 1997 and knows local permitting under ESR-1790. The current promotion offers no payments and no interest until Spring 2027, or 10% off installation.
Is a metal roof a good choice for Puget Island’s climate?
Yes. Puget Island averages about 55 cm of snow, 1805 mm of rain, roughly 22 freeze–thaw days a year, with peak wind gusts near 97 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.
