Interlock® Aluminum Roofing — all-climates performance specs for Weatherwax, 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 Weatherwax
The following metal roofing FAQs are designed specifically for homeowners in Weatherwax, 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 Weatherwax.
Will a metal roof handle Weatherwax's snow load and ice dams?
Yes—aluminum's light weight (the Shake profile installs at just 0.58 lb/sq ft) puts zero strain on your framing, even under Grays Harbor's average 104 cm of annual snowfall. The smooth, interlocking panel design sheds snow and ice naturally without the pooling that traps moisture on asphalt. The four-way interlock also means no exposed fasteners for ice to pry open. In a climate with roughly 38 freeze-thaw cycles per year, that matters: your roof expands and contracts, but the panels stay locked together.
How does a metal roof perform in Weatherwax's heavy rain?
Interlock panels shed water by design—they're engineered to overlap and channel runoff downward, so with Grays Harbor averaging 2523 mm of annual rainfall, there's no standing water or pooling. The four-way interlock creates a continuous barrier; each panel locks to its neighbors, so water never finds a gap. Installed over a solid deck with underlayment (standard practice), the system is as leak-proof as any roof. Metal reflects rain noise rather than transmitting it, and the deck underneath silences it completely—you won't hear weather.
Can Interlock metal roofing withstand Weatherwax's wind gusts?
The four-way interlock locks each panel to its neighbors horizontally and vertically, creating a unified assembly that resists wind uplift. Interlock is warranted to resist sustained winds up to 120 mph; Weatherwax's typical gusts reach about 106 km/h (66 mph), well within the safety margin. In a climate where storm gusts are routine, that interlocking grip means panels won't separate, curl, or lift. The warranty covers wind damage when installed to spec, giving you certainty that your roof will still be there after the season's worst blow.
Does metal roofing protect against hail and qualify for insurance breaks?
Interlock carries a UL 2218 Class 4 impact rating—the highest available—and the warranty even covers perforation from hailstones up to 1.5 inches. Aluminum's strength-to-weight ratio (the Tile profile is about 96% lighter than concrete or clay tile) means it absorbs impacts without cracking or shattering the way slate, tile, and wood do. Many insurers recognize that durability and offer discounts on metal roofs. In Grays Harbor's storm-prone climate, that translates to lower premiums over decades—often recovering the roof's cost.
What's the real lifespan of an Interlock metal roof, and what does the warranty cover?
Interlock carries The Guardian lifetime limited warranty for the original owner—non-prorated material coverage for rusting, rotting, splitting, cracking, curling, and loss of impact resistance. It's also transferable: the next owner gets 50 years from completion. That's a fundamentally different promise than asphalt, which degrades within 15–20 years. Manufactured since 1998 and installed from coastal homes to an Antarctic research station, Interlock panels have proven themselves across climates far harsher than Weatherwax. You're buying a roof that will outlast the mortgage.
Will I need to reinforce my home's structure for a metal roof?
No. The Slate profile installs at 0.41 lb/sq ft, the Mediterranean Tile at 0.59 lb/sq ft—about 96% lighter than real tile or concrete tile. Most homes can accept a metal roof without any structural work. This also means you can install directly over an existing asphalt roof, eliminating the cost and waste of tear-off and disposal. Weatherwax homeowners benefit twice: they avoid expensive framing upgrades, and they skip the landfill impact of their old roof. The ICC-ES ESR-1790 evaluation (reissued 2025) confirms code compliance without reinforcement on standard residential framing.
Is metal roofing worth the upfront cost in Weatherwax?
Compare the life-cycle cost, not the sticker price. Asphalt needs replacement every 15–20 years; you'll buy two or three asphalt roofs in the time one metal roof lasts. Interlock's lifetime warranty and proven durability across 25+ years of installation mean no re-roofing in your lifetime. Factor in no storm damage claims (UL 2218 Class 4, 120 mph wind warranty), potential insurance discounts, and energy savings (energy-efficiency colors reflect 55% of solar radiation), and the metal roof becomes the last roof you buy. In Grays Harbor's harsh freeze-thaw climate (38 days per year), that's protection asphalt simply cannot match.
Is metal roofing actually better for the environment than asphalt?
Aluminum is approximately 95% recyclable—the panels themselves and all offcuts go back to the metal stream indefinitely. Asphalt shingles, by contrast, end up in landfills after 15–20 years and never fully decompose. Interlock, manufactured in Delta, BC since 1998, breaks the tear-off-to-landfill cycle entirely. You install once, and the material cycle closes at end of life. Weatherwax's 2523 mm of annual rainfall and 38 freeze-thaw days would degrade asphalt steadily; a metal roof eliminates that waste stream and leaves no environmental debt to the next homeowner.
How much maintenance does a metal roof actually need?
Almost none. Unlike wood shake or shake roofing, aluminum panels don't split, rot, or warp as Weatherwax's 2790 annual sunshine hours and frequent rain cycles cycle between wet and dry. Unlike asphalt, they don't shed granules or need sealing every few years. Occasional gutter cleaning and an inspection after major storms are sufficient. The Alunar coating is warranted 30 years against chalking and fading (energy-efficiency colors hold their reflectance far longer than painted steel). CALGreen verifies the system for reduced maintenance, so your only task is enjoying 25+ years of worry-free weather protection.
Who installs Interlock roofing in Weatherwax, and how long have they been in business?
Interlock Metal Roofing (PNW) Inc. has served Grays Harbor County since 1997—longer than the Interlock product line itself has been manufactured. They know Weatherwax's climate intimately: the gusts to 106 km/h, the 104 cm of snow, the freeze-thaw cycles that challenge any roof. Local installers understand site-specific details—existing structure, drainage, wind exposure—that determine proper installation and warranty validity. With 1997 roots in the region, they're invested in long-term reputation, not one-time sales. Currently, they're offering no payments and no interest until Spring 2027, or 10% off installation.
Is a metal roof a good choice for Weatherwax’s climate?
Yes. Weatherwax averages about 104 cm of snow, 2523 mm of rain, roughly 38 freeze–thaw days a year, with peak wind gusts near 106 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.
