Interlock® Aluminum Roofing — all-climates performance specs for Grays River, 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 Grays River
The following metal roofing FAQs are designed specifically for homeowners in Grays River, 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 Grays River.
Does a metal roof handle heavy snow and ice in Wahkiakum County winters?
Yes—Interlock's four-way interlocking aluminum panels are engineered to support snow loads without the ice-dam problems that plague asphalt. With Grays River averaging 49 cm of snow annually and about 34 freeze-thaw cycles per year, the smooth, hard surface naturally sheds meltwater and resists ice buildup. Snow guards are available if you want to control slide patterns. The panels' lightweight design (0.41–0.59 lb/sq ft depending on profile) means no structural reinforcement needed, unlike slate or concrete tile, yet they perform identically for load capacity.
Will a metal roof leak in Grays River's wet climate?
No—Interlock panels shed water by design. Grays River receives approximately 1578 mm of rain annually, and the four-way interlocking system creates a waterproof barrier when installed to spec over solid deck and underlayment. The interlocking seams are mechanically fastened, not glued, so they remain watertight through thousands of rain cycles. Installation over your existing roof (if sound) eliminates exposure during the install process, further reducing leak risk. ICC-ES ESR-1790 compliance confirms water management under IBC/IRC standards.
Can a metal roof rust in a wet, coastal climate like Grays River?
Aluminum cannot rust because it contains no iron—the metal's protective oxide layer actually self-heals when scratched. This matters in Wahkiakum County's salt-influenced maritime air and frequent moisture. Interlock uses roofing-grade 3105-H24 / 3003-H24 aluminum (ASTM B209) with a Alunar® 70% PVDF fluorocarbon finish applied to both sides, warranted 30 years against chalking and fading. Steel roofing, by contrast, requires constant rust vigilance. After 27 years of installations from coastal homes to Antarctic stations, Interlock panels show no corrosion—only the aesthetic patina of weathered aluminum.
Does hail damage metal roofs, and can I get an insurance discount?
Interlock metal roofs are extraordinarily hail-resistant, rated UL 2218 Class 4 (the highest impact rating available). The warranty covers perforation from hailstones up to 1.5 inches. Many insurers recognize this durability and offer premium discounts on metal roofing. When you contact your agent, reference the UL 2218 Class 4 rating and the Guardian lifetime warranty. Grays River's wind gusts reach 103 km/h and weather patterns can produce severe spring storms, so impact resilience protects both your home and your long-term insurance costs.
Is metal roofing more expensive than asphalt when you factor in lifespan?
Metal roofing costs more upfront but eliminates the asphalt cycle—no tear-offs, no re-roofing every 15–20 years. Over 50+ years, the total cost of ownership is substantially lower. Interlock's Guardian warranty is lifetime limited and non-prorated for the original owner, then transferable for 50 years to the next owner. With Grays River's 1578 mm annual rainfall and 49 cm snow, asphalt degrades faster from moisture and UV cycling than in drier regions. The current regional promotion offers no payments and no interest until Spring 2027 or 10% off installation, making the transition more affordable now.
What maintenance does a metal roof need compared to asphalt or wood shake?
Metal roofs require minimal maintenance. Interlock aluminum panels shed debris naturally and do not require roof washing, algae treatment, or moss removal like asphalt, wood shake, or cedar shingle roofs do—especially in Grays River's moist 2757 annual sunshine hours and frequent rainfall. No nail pops, no curling, no rot or splitting to monitor. The 30-year Alunar® coating is warranted against chalking and fading (measured to ASTM D4214 / D2244 standards), and the aluminum's self-healing oxide layer resists scratches. Essentially, you install it and stop worrying about your roof.
Can my home's structure support a metal roof, or do I need reinforcement?
No structural reinforcement is needed. Interlock's Mediterranean Tile profile, for example, weighs approximately 0.59 lb/sq ft—about 96% lighter than concrete or clay tile. Even the Shake profile at 0.58 lb/sq ft is negligible compared to slate or ceramic. Most homes can support metal roofing over an existing asphalt roof with zero additional framing. This lightweight advantage means you install over your current roof in most cases, saving on tear-off labor and landfill costs. The panels' aluminum construction (ASTM B209) delivers strength and durability without the dead load penalty of traditional materials.
Will a metal roof hold up to Grays River's winter and spring gusts?
Yes—Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to spec. Grays River's typical gusts reach 103 km/h, well within the panels' performance envelope. The four-way interlocking design creates mechanical strength at every seam; fasteners lock panels together so uplift forces are distributed across the roof system rather than concentrated at individual attachment points. The design has been field-proven in coastal regions where sustained winds and rapid pressure changes are common. ICC-ES ESR-1790 confirms compliance with wind-load requirements in the IBC/IRC.
Is a metal roof fireproof or fire-rated?
Interlock metal roofing is non-combustible and available in Class A fire-rated profiles. Aluminum cannot ignite or contribute to flame spread. This matters in any region prone to wildfires or where fire-safety codes are tightening. The ICC-ES ESR-1790 evaluation (reissued 2025) confirms compliance with IBC/IRC fire classifications, and Interlock's profiles achieve Class A status without additives or treatments. Grays River's 2757 annual sunshine hours and regular moisture mean wildfire risk is lower than inland regions, but the non-combustible designation provides additional peace of mind and may lower your homeowners insurance in the future.
How long does metal roof installation take, and can it go over my existing roof?
Installation typically takes 1–3 days depending on roof complexity. Yes, Interlock panels install over most existing asphalt roofs if the deck is sound and well-fastened. This approach eliminates tear-off labor, dumpster costs, and weather exposure during installation—a significant advantage in Grays River's average 1578 mm annual rainfall. Your installer will inspect the existing deck, add underlayment and flashing where needed, and mechanically fasten the panels. Interlock Metal Roofing (PNW) Inc. has served the region since 1997 and knows local conditions and building departments. Expect a site visit, written estimate, and scheduling within 1–2 weeks for most jobs.
Is a metal roof a good choice for Grays River’s climate?
Yes. Grays River averages about 49 cm of snow, 1578 mm of rain, roughly 34 freeze–thaw days a year, with peak wind gusts near 103 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.
