Interlock® Aluminum Roofing — all-climates performance specs for Zillah, 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 Zillah
The following metal roofing FAQs are designed specifically for homeowners in Zillah, 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 Zillah.
Will a metal roof handle Zillah's winter snow and ice buildup?
Metal roofs shed snow and ice effectively due to their smooth, hard surface and excellent thermal properties. Zillah receives about 112 cm of snow annually with roughly 101 freeze-thaw cycles per year—conditions where ice dams commonly damage asphalt roofs. Interlock's aluminum panels, warranted to 120 mph winds, remain secure even when snow loads shift. The non-combustible finish doesn't degrade in freeze-thaw cycling, and snow guards (optional) can be added if you prefer controlled shedding. Your roof's integrity won't suffer from the repeated expansion and contraction that compromises traditional materials.
How does freeze-thaw weathering affect metal roofing in Washington winters?
Freeze-thaw damage occurs when water penetrates material, freezes, expands, and cracks it—but aluminum's oxide layer prevents water absorption entirely. Unlike asphalt shingles (which crack and curl) or wood shakes (which split), Interlock's 3105-H24 aluminum alloy is immune to this cycle. With Zillah averaging 101 freeze-thaw days per year and 112 cm of snow, your roof faces this stress continuously. The Alunar 70% PVDF coating adds extra durability, warranted 30 years against breakdown. Your roof will look and perform identically in year 30 as it did in year one.
Can a metal roof rust? What about salt air or moisture in Yakima County?
Aluminum cannot rust because it contains no iron—the element that oxidizes and weakens steel roofs. Instead, aluminum forms a thin oxide layer that self-heals when scratched, protecting the metal beneath indefinitely. Interlock's roofing-grade 3105-H24 and 3003-H24 alloys (ASTM B209) are specifically formulated for coastal and high-moisture environments, with the Alunar finish applied to both panel sides for extra protection. Even in Zillah's wet climate—336 mm of annual rainfall plus 112 cm of snow melt—your aluminum roof will never corrode, rust through, or require replacement due to material degradation.
Do I need to reinforce my roof structure to support a metal roof?
No structural reinforcement is needed. Interlock's aluminum panels are extraordinarily light—the Slate installs at just 0.41 lb/sq ft, and even the decorative Tile profile weighs only about 0.59 lb/sq ft, roughly 96% lighter than actual clay or concrete tile. Your existing framing easily supports this weight, and the roof can install directly over most current asphalt or wood shingles without costly structural work. This lightweight advantage, combined with ICC-ES evaluation (ESR-1790), means installation is faster and less expensive than traditional tile. You get architectural beauty without engineering costs.
What hail rating does a metal roof have, and will it lower my insurance?
Interlock metal roofing holds the highest available hail impact rating: UL 2218 Class 4, which covers perforation from hailstones up to 1.5 inches. This rating reflects real impact resistance that protects your roof in severe weather. Many insurers recognize this top classification and offer premium discounts on metal roofs compared to asphalt shingles, which dent and puncture easily. The Guardian warranty even covers hail damage specifically. While Zillah's annual wind gusts reach about 87 km/h, hail events are less frequent here than in higher-elevation regions—but when they occur, your roof's documented impact strength and warranty give you peace of mind and potential cost savings on premiums.
How much upkeep does an Interlock metal roof require versus asphalt or tile?
Metal roofing requires virtually no maintenance—no algae treatment, no shingle replacement, no wood repair. Unlike asphalt shingles (which degrade visibly within 15–20 years), Interlock aluminum panels resist weathering, UV exposure, and biological growth indefinitely. With Zillah's 336 mm annual rainfall and 3,478 sunshine hours, asphalt roofs require frequent inspections and repairs; metal roofs simply shed water and debris. The Alunar coating is factory-applied and warranted 30 years against chalking and fading, so repainting is never needed. Traditional tile roofs crack and require replacement—metal tile profiles never do. You gain a maintenance-free roof that ends the asphalt replacement cycle.
How much does a metal roof cost versus asphalt over its lifetime?
Over the roof's lifetime, metal roofing is the lowest-cost option—it's your last roof. While the upfront price exceeds asphalt, the lifespan math is decisive: asphalt roofs last 15–25 years and require tear-off and landfill disposal (expensive and wasteful); Interlock's Guardian warranty is lifetime limited, non-prorated for the original owner. If you live in your home 30+ years, asphalt will need replacement; your metal roof will not. The current regional promotion—no payments and no interest until Spring 2027, or 10% off installation—makes this the ideal time to invest. Over a 40-year ownership span, one metal roof costs far less than two or three asphalt roofs, plus avoids multiple contractor visits and roof-off downtime.
Will a metal roof reduce my cooling costs in Zillah's sunny climate?
Metal roofs with reflective coatings measurably reduce cooling costs by bouncing solar heat away rather than absorbing it into your home. Interlock's energy-efficient colors achieve thermal emissivity of 0.84 and solar reflectance up to 0.55, meaning they reflect the heat that dark asphalt absorbs. Zillah enjoys approximately 3,478 sunshine hours annually—abundant solar exposure where reflectance matters. Cool Roof Rating Council certification confirms this performance in third-party testing. The lighter thermal load reduces air-conditioning runtime, especially during summer peak demand. While Zillah's winters are cold, the non-combustible aluminum never compromises insulation, and the energy savings build over decades. energy-efficiency qualification recognizes the measurable reduction in cooling energy.
How long does installation take, and can you install over my existing roof?
Installation timelines vary by roof size, typically 3–7 days for a standard residential home. Interlock Metal Roofing (PNW) Inc., serving this region since 1997, handles local scheduling and has extensive experience with Yakima County conditions. Yes, the lightweight design (Slate at 0.41 lb/sq ft) allows installation directly over most existing asphalt or wood shingles—no tear-off required, which saves labor and eliminates the landfill cost of old roofing. The four-way interlocking aluminum panels lock together securely, meeting ICC-ES ESR-1790 standards for IBC/IRC compliance. Your installer will confirm your existing structure can accommodate the new roof; in almost all Zillah homes, no reinforcement is needed. Installation over existing roof means your home stays protected and clean throughout the project.
What's the actual lifespan of a metal roof, and what does the warranty cover?
The Guardian warranty is lifetime limited, non-prorated for the original owner, covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance—the exact failures that end asphalt and wood roofs. Aluminum's inherent durability, proven through 25+ years of manufacturing (since 1998 in Delta, BC) and installation from coastal salt air to Antarctica, demonstrates real longevity. The warranty is one-time transferable to the next owner for 50 years from completion, making your roof a lasting asset. No time limit means your roof is protected for decades of Zillah's rainfall (336 mm annually), freeze-thaw cycles (101 per year), and wind gusts (to 87 km/h). This non-prorated protection stands apart from asphalt warranties, which decline in coverage year by year. You own a roof that lasts your lifetime and beyond.
Is a metal roof a good choice for Zillah’s climate?
Yes. Zillah averages about 112 cm of snow, 336 mm of rain, roughly 101 freeze–thaw days a year, with peak wind gusts near 87 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.
