Interlock® Aluminum Roofing — all-climates performance specs for Ayock, 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 Ayock
The following metal roofing FAQs are designed specifically for homeowners in Ayock, 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 Ayock.
Does metal roofing handle heavy snow and ice in Lewis County winters?
Yes. Interlock's four-way interlocking aluminum panels are warranted for wind speeds up to 120 mph, and the lightweight design (Cedar Shingle at 0.41 lb/sq ft) eliminates snow load strain on your home's frame. Ayock receives about 33 cm of snow annually with roughly 16 freeze-thaw cycles per year—conditions that cause asphalt to crack and curl. Aluminum's oxide layer doesn't degrade in freeze-thaw, and the panels shed ice and snow efficiently due to their smooth, interlocked profiles. Optional snow guards can be added if extra retention is needed for safety.
Will a metal roof leak in Ayock's rainy climate?
No. Ayock averages 1362 mm of rainfall yearly, and Interlock's four-way interlocking panels create overlapping seams that shed water downward—the system is engineered to drain rather than collect. The panels install over solid decking with underlayment, which prevents water bypass at fasteners or seams. ESR-1790 code compliance confirms the design meets IRC/IBC leak requirements, and the Guardian Warranty covers perforation and water intrusion. Proper installation by our local team ensures flashing details handle the region's consistent rain without pooling or saturation risk.
Why choose aluminum roofing instead of steel if both are metal?
Aluminum cannot rust. Steel contains iron, which oxidizes in moisture; aluminum's oxide layer is passive and self-heals when scratched. With 1362 mm annual rainfall and frequent freeze-thaw cycles in Ayock, steel requires ongoing maintenance to prevent rust creep. Interlock uses roofing-grade 3105-H24 aluminum (ASTM B209) with a dual-coat Alunar 70% PVDF finish applied to both panel sides—extra critical in our wet climate. The Guardian Warranty explicitly covers rusting. Aluminum installed in 1998 at Antarctic research stations and coastal salt-air homes proves durability; your roof won't develop the orange streaking or perforation that compromises steel over 20–30 years.
Can my house support a metal roof, or do I need structural upgrades?
No structural upgrades needed. Interlock's Shake profile weighs only 0.58 lb/sq ft—about 96% lighter than concrete or tile—so the load on your framing is negligible. Asphalt shingles weigh roughly 2–3 lb/sq ft; aluminum metal roofing actually reduces dead load. This means the system installs directly over most existing roofs without reinforcement, lowering labor costs and installation time. In Ayock's snow climate (33 cm annually), lighter roofing improves structural efficiency during freeze-thaw stress. ESR-1790 evaluation confirms installation over existing decks on standard residential framing; your roofer will inspect your deck during a site visit.
How much upkeep does a metal roof need compared to asphalt or tile?
Metal requires almost none. Asphalt shingles need moss removal, regular inspections for curl and loss, and repairs after hail or wind gusts (Ayock averages 90 km/h gusts). Concrete tile cracks in freeze-thaw cycles. Aluminum panels are CALGreen-verified for reduced maintenance—no algae growth, no debris trapping, no sealant reapplication. Twice-yearly gutter cleaning is standard for any roof. The 30-year Alunar coating warranty (ASTM D4214/D2244 tested) means no color fading or chalking, so you won't repaint. With 2915 annual sunshine hours and natural rainfall, dirt rinses away. The Guardian Warranty covers splitting, cracking, and curling—problems that plague traditional materials in your freeze-thaw zone.
What's the actual lifespan of Interlock metal roofing and what does the warranty cover?
Interlock carries the Guardian Warranty—a lifetime limited, non-prorated material warranty for the original owner covering rusting, rotting, splitting, cracking, curling, and impact loss. The warranty is one-time transferable, giving the next owner 50 years of coverage from completion. This is the only roof you'll install. Asphalt lasts 15–20 years and requires tear-off disposal (landfill waste); wood shakes split and rot within 20–25 years in Ayock's 1362 mm annual rainfall and 16 freeze-thaw days. Aluminum panels manufactured since 1998 in Delta, BC show no degradation after 25+ years. No other roofing material covers perforation from hailstones up to 1.5 inches (UL 2218 Class 4) or 120 mph winds for the life of the home.
Does metal roofing save money on heating and cooling?
Metal roofing cuts cooling costs year-round. Interlock's energy-efficient colors reflect solar heat rather than absorb it—reflectance values up to 0.55 (Aged Copper Penny) and thermal emissivity 0.84 cool your home in summer. Even in Ayock's moderate 11.6°C mean temperature, the 2915 annual sunshine hours mean reflective roofing reduces HVAC strain during warm months. Asphalt absorbs heat, raising attic temperatures 20–30°F above ambient—a penalty in summer and a burden on air conditioning. Cool Roof Rating Council certification proves the energy benefit. In winter, the same reflective surface won't prevent heat loss, but no roofing system does; the real advantage is summer comfort and lower cooling bills without added maintenance like coatings or sealants.
Will my metal roof blow off in Ayock's wind and gust conditions?
No. Interlock panels are warranted to withstand wind speeds up to 120 mph when installed to specification. Ayock's typical winds average 16 km/h with gusts recorded to 90 km/h—well within that margin. The four-way interlocking design means each panel locks to its neighbors on all sides, creating a unified system rather than individual shingles. UL testing (UL 2218 Class 4 hail rating also demonstrates structural integrity) confirms uplift resistance. Asphalt shingles blow off at 60–80 mph and degrade faster in wind-driven rain. Our local Interlock installer has served the Pacific Northwest since 1997 and understands regional wind patterns; proper fastening and flashing technique ensures your roof stays put.
Is metal roofing worth the upfront cost compared to asphalt shingles?
Yes, over the life of your home. Asphalt costs $3–5 per square foot installed and lasts 15–20 years; you'll replace it 2–3 times. Metal costs more initially but lasts 50+ years with zero tear-off, no landfill disposal, and no maintenance bills. The Guardian Warranty is lifetime for you and transferable 50 years for the next owner—no other material matches that. Ayock's harsh climate (1362 mm rain, 33 cm snow, 16 freeze-thaw cycles) accelerates asphalt failure; your third roof will arrive while paying off the second. Energy savings from reflective coatings also offset costs in sunny periods. We're currently offering no payments and no interest until Spring 2027 or 10% off installation—financing makes metal affordable upfront while you recoup value through longevity and avoided replacements.
Is metal roofing fire-safe for homes in Washington?
Absolutely. Interlock aluminum is non-combustible and achieves Class A fire classification (the highest available per ASTM and UL standards). Aluminum contains no wood fiber or petroleum binders; it cannot ignite or contribute fuel to a fire. ESR-1790 code compliance confirms suitability under IBC/IRC, and the ICC-ES report (reissued 2025) covers residential application throughout Washington. Asphalt shingles are Class C or lower and release flammable gases under high heat. In Ayock's wet climate with 2915 sunshine hours, wildfire risk varies by location, but metal roofing eliminates one variable from your home's defensibility. Combined with Class 4 hail impact rating, the system also resists wind-driven ember penetration better than traditional materials. Your home insurer may offer premium discounts for non-combustible roofing.
Is a metal roof a good choice for Ayock’s climate?
Yes. Ayock averages about 33 cm of snow, 1362 mm of rain, roughly 16 freeze–thaw days a year, with peak wind gusts near 90 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.
