Interlock® Aluminum Roofing — all-climates performance specs for Deep 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 Deep River
The following metal roofing FAQs are designed specifically for homeowners in Deep 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 Deep River.
How does a metal roof handle Deep River's snow and ice buildup?
Metal roofs shed snow more reliably than asphalt because the smooth, hard surface resists ice bonding and the lightweight panels won't sag under load. Deep River averages about 49 cm of snow annually across roughly 34 freeze-thaw cycles, which create conditions where ice dams commonly form on softer roofing. Interlock's four-way interlocking aluminum panels—each weighing as little as 0.41 lb/sq ft for the Shingle profile—remain structurally sound through repeated freeze-thaw stress. Snow guards are available if you want to manage slide-off, but many homeowners here appreciate the natural shedding that reduces ice dam risk during the region's typical winter warm spells.
Why won't my aluminum metal roof rust like steel roofs can?
Aluminum cannot rust because it contains no iron; instead, it forms a protective oxide layer that self-heals when scratched. Interlock's roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209 certified) is coated on both sides with Alunar 70% PVDF fluorocarbon finish, which adds an extra corrosion barrier even in salt-air environments. In Deep River, where you receive about 1578 mm of annual rainfall and coastal moisture can carry salt inland through Wahkiakum County, this dual-layer protection means you're not fighting rust year after year like steel roofs require. The Guardian Warranty explicitly covers rusting—an issue that simply doesn't apply to aluminum.
Does a metal roof hold up to hail, and can I save on homeowner's insurance?
Yes—Interlock metal roofing carries a UL 2218 Class 4 impact rating, the highest available, and the warranty even covers perforation from hailstones up to 1.5 inches. That durability often qualifies homeowners for insurance discounts; contact your agent with the UL 2218 rating to ask. Deep River's typical wind gusts reach about 103 km/h, which can accompany severe weather, so impact resistance matters. Because metal roofs rarely need replacement after hail damage (unlike asphalt shingles, which degrade and leak), you're also avoiding the hidden costs of repeated claim deductibles over the roof's life. Many insurers now recognize this and reward metal-roof owners with rate reductions.
Will a metal roof leak during Deep River's heavy rainfall?
The four-way interlocking design creates a continuous mechanical seal across the entire roof panel, so water cannot channel between panels or find a way through. With about 1578 mm of rainfall annually in Deep River, a properly installed metal roof's interlocking ridges simply shed water faster than it can pool. Add a solid deck and underlayment—standard in professional installation—and you get the same water-shedding performance as asphalt, without the asphalt's eventual granule loss and clogging of gutters. The ICC-ES evaluation report (ESR-1790) confirms the design under code-standard rain exposure testing. After 27 years of installations from coastal salt-air homes to Antarctic research stations, Interlock's track record in wet climates speaks to reliability.
Can a metal roof stand up to the wind gusts we get here?
Interlock metal roofing is warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Deep River's typical gusts reach about 103 km/h, well within that safety margin. The four-way interlocking aluminum panels lock together mechanically, so wind cannot lift or separate individual panels the way it can peel asphalt shingles or tiles. Because the panels weigh as little as 0.41 lb/sq ft, they resist flutter and vibration even in strong gusts. That combination—lightweight, interlocked, and engineered to code—means your roof will still be intact after decades of the region's typical winter and spring wind events.
Do I need to reinforce my house's structure for a metal roof?
No—aluminum's light weight eliminates the need for structural reinforcement. Interlock's Mediterranean Tile profile, for example, weighs about 0.59 lb/sq ft, roughly 96% lighter than concrete or clay tile, so it installs directly over most existing roofs without additional support. Compare that to slate or traditional tile, which require bracing and sometimes new framing. In Deep River, where you average about 49 cm of snow per year, an asphalt roof and a metal roof load your house similarly—but the metal roof will still be protecting you decades later. The ICC-ES evaluation report (ESR-1790) confirms that Interlock meets code requirements for roof load without additional structural work.
How long does a metal roof last, and what does the warranty 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's also one-time transferable, giving the next owner 50 years of coverage from installation completion. The 30-year coating warranty (Alunar PVDF, ASTM D4214/D2244 tested) protects against chalking and fading. Many Interlock roofs installed in the 1990s are still performing in coastal and mountain climates far harsher than Deep River's roughly 2757 annual sunshine hours and 1578 mm rainfall. A metal roof is realistically your last roof; you won't be tearing it off and paying landfill fees again.
Can I get a metal roof that looks like slate, shake, or tile?
Absolutely—Interlock offers five profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each profile replicates the texture and depth of traditional materials using four-way interlocking aluminum panels. Whether you prefer the clean lines of slate, the rustic character of cedar shake, or the old-world charm of Mediterranean tile, the aluminum construction performs identically—it won't degrade the way wood shakes absorb moisture during Deep River's about 1578 mm of annual rainfall, and it won't crack like clay tile under the region's 34 annual freeze-thaw cycles. The Alunar PVDF coating comes in many colors, including period-authentic options like Aged Copper Penny (0.55 solar reflectance), so you're not choosing between looks and durability.
Is a metal roof more environmentally responsible than asphalt?
Yes—Interlock aluminum roofing is approximately 95% recyclable and ends the asphalt tear-off-to-landfill cycle that repeats every 15–20 years. Because a metal roof lasts 50+ years and is transferable to the next owner, you're installing once and protecting your home for generations instead of creating multiple disposal events. Aluminum's recyclability also means your roof has post-consumer value at end of life, unlike asphalt shingles. In Wahkiakum County, where water quality and forest health matter, avoiding the repeated environmental cost of asphalt replacement—from manufacturing emissions to landfill leachate—is a meaningful choice. The roof also qualifies as CALGreen-verified for reduced maintenance, reflecting lower ongoing environmental impact.

Yes. Deep 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.
