Interlock® Aluminum Roofing — all-climates performance specs for Kellys Corner, 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:
They did a very good job! They did a good job. We have had a wind storm and rain, and no leaks.
There could be improvement regarding communication of what days they were working and what days they weren't. I wish I had gotten the roof years ago. It wasn't as a good a fit on our old house. We knew we wanted to do this house and we finally got the money together to do it. We are so glad we did.
Interlok Reps came across as high-pressured and as if trying to 'pull fast ones', like:----Demanding all homeowners be present for sales pitch, though I assured him we'd already been shown the product, only needed estimate and verification of materials; then if it looked feasible, then paperwork. ----Entire sales pitch felt high-pressured. ----We clearly and repeatedly stated, Interlok was far beyond our means to afford or finance, after they'd quoted prices, yet Reps continued to high-pressure and jig-figures by small amounts. ----Rep pulled out contract papers, despite being told we can't afford this; papers looked as if we needed a legal team to read and edit them, to have ANY hope of legal protections.Reps said a few things which conflicted with other statements in their pitch, as well as some bordering on sounding like scamming, like: ==="Standing seam roofing has fasteners that show"; Despite indicating our better-than-average knowledge of roofing and building, Reps emphatically tried to convince us of other metal roofing's inferiority by mis-stating facts, then changing subject. ==="Must include permit cost"; Our County does NOT require permit to replace roofing unless framing/structure needs fixed--ours does not: the roof deck is NOT considered structure for purposes of re-roofing. ==="We can roof-over the existing 2 layers of shingles to save you a big chunk off the price" ;But this was still more than double the cost of standing-seam; and, CODE:requires "must remove all old roofing if there is more than one layer of old roofing"...He knew this Code requirement to start with, stating it clearly at the beginning, then tried to buffalo us that we could get away without removing old roofing, after it was made clear to him YET AGAIN, that cost was crucial, and that we could NOT afford this: Conclusions: 1. He intended to bait-and-switch, and/or do an illegal job. 2. If he so easily used these tactics, what else was lied about or misled about?Cost, function and honesty trump Cosmetics. Notes re: realty/housing industries in general:The Interlok Reps came on the heals of our being sold a money-pit. We'd already gone deep into debt to repair/replace basic infrastructure which should have been done before being put on the market. Realtors and affiliated industries extensively use deceptive descriptives and practices to artificially pump prices, all over three counties we looked in; this was the best one we could find, and it was misrepresented and over-priced. The cunning, clever ways the various industries work together regarding real estate, allows each separate industry to appear mostly guiltless. "House flippers" routinely cover up infrastructure issues with cosmetics, and make more mistakes of their own which also need fixed. "Instant equity" appears to be a housing industry Secret Code for: "this is how much we KNOW it will take to fix things we're not telling buyers about, which can't be seen by inspectors buyers pay for, or items which are marginal or fall through Code cracks". Honesty, accountability and responsibility take a back-seat to getting fast money, at most levels, at least to some degrees. Better changes need made, but in today's sick business climate, that's not likely to happen fast enough to prevent more new homeowners losing their homes related to these issues. Too many industries, in every sector, have predatory and/or destructive practices which they continue to rationalize and excuse, to maintain business-as-usual. We'd also already been blitzed with questionable to shady contractors prior to Interlok Reps arrival, therefore sensitized to any hints of questionable business practices. More varieties of contractors and businesses have been knocking on our door and spamming our mail since then.
Factory to installers communication, shipping, and their materials breakdown was the only problem we really had. The roof was pretty much wide open for about two weeks exposed to the elements. Loan company used, a pain to work with
I have enjoyed the new roof you have installed for almost a year now, and I want to say I am so pleased with it. Best of all it was recognized in my taxes and that was especially nice. I have to admit, I have the best looking roof in my neighborhood and it is permanent.
The Interlock associate Ivan,came did an awesome service in correcting the part needed to be corrected, he left us with instructions of what we needed to check and to get in touch with, if needed 😀 Ms. May the associate answering the phone was helpful for us to get prompt service. They are dependable. We received roof service.
Dear Interlock Roofing, Thank you for coming by and installing a new roof on our house. After we first talked at the Tacoma Home Show in January, both Paul and Ross were fantastic in walking us through the process and explaining the roofing system when we met in February. They answered all our questions, and we were eager to get started. Patrick and Drew took the lead with the installation planning and paperwork, and once the materials were ready in May, Patrick dropped them off at our house. The three-man crew installed everything in three days and ensured any installation questions were answered and done properly. In the end, we love the look and expected longevity of our new roof.
By far the best purchase we’ve made for our home. Patrick and Greg were amazing! Installation was quick and there wasn’t any mess left behind. If you have ever thought about getting a metal roof Interlock Roofing is hands down the best!
The cost of the roofing was too high. It looks very nice and glad I had it installed. I have one leak, but I haven't called them about it yet.
The sale experience was good, but the rest was far below expectations, especially for the price paid. We did not buy Interlock just for an attractive roof, we bought it because they are supposed to be experts, have a high level of customer services, and we thought would do things right without headaches. This is far from the case. Hire an company who's actual employees and managers will be on site, not Interlock. Turns out we were actually blindly hiring a crew, who sub-contracts for Interlock, and has a questionable level of experience. Interlock doesn't even show up at your job site at any time during the job, even if you have problems and repeatedly ask them to. Once they have your money at the end of the job, they don't care if you still have issues or even bother to respond to you when you have additional issue. They need an interlock staff member who is an installation expert to be on the job site ideally for the whole job, but at the least, at the start at the middle and at the end who can insure everything is done to high standards and that all of the customers issues are addressed promptly. Paying by the job is also super problematic, this only encourages the crews to work as fast as they possibly can, covering up or ignoring things that might take a bit longer. They have no incentive to fix or give the customer time to fix an issue. The one installation manager you have for a huge region is not even close to adequate, it's no surprise he could not give us an adequate level of communication or attention. Disappointing.
Their workers are very good and very capable. Fewer supply problems. Joe, the scheduler. He does an exceptional job keeping his customers happy and meeting schedules considering supply and covid issues. Always nice and courteous.
They fell short with the roofing underlayment material. The type of boards they actually used. Maybe since they used one over another, they probably need to be more clear and advise the customer who chooses. It is something we noticed. Contact from the company for rescheduling could've been better. I understand delays are unforeseen, but keeping better communication with consumers so they aren't taking time off and then finding it wasn't necessary to do so due to a delay. They were quick to request a referral, which I gave them a good one online, but they were slow when it came time to take care of the damage done. They probably should've waited to ask for the referral until after they had repaired the damage. Now, we feel hurried for a great referral, but they are taking their time to come back for the damage. I look forward to recommending them. This project was referred to us by friends in the midwest. I hope the company follows through on the $500 referral.

Metal Roofing FAQs for Homeowners in Kellys Corner
The following metal roofing FAQs are designed specifically for homeowners in Kellys Corner, 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 Kellys Corner.
How does metal roofing handle heavy snow in Kellys Corner?
Metal roofing sheds snow effectively because of its smooth, interlocking surface and low coefficient of friction — especially important in Thurston County, where you average about 40 cm of snow annually and experience roughly 34 freeze-thaw cycles per year. The four-way interlocking aluminum panels are warranted to resist wind gusts up to 120 mph, which prevents the shifting and gaps that can trap snow and ice. Optional snow guards are available if you want to control sliding on steep pitches. Unlike asphalt, which absorbs moisture and deteriorates through repeated freeze-thaw cycles, aluminum's self-healing oxide layer remains intact year after year, so performance stays consistent through decades of Kellys Corner winters.
Can aluminum metal roofs rust? Why is that better than steel?
Aluminum cannot rust because it contains no iron — the element that oxidizes when exposed to water and oxygen. Instead, aluminum develops a transparent oxide layer that actually protects the metal underneath, and if that layer gets scratched, it self-heals when exposed to air. In Kellys Corner, where annual rainfall reaches about 1370 mm and moisture is constant, this is a major advantage. Interlock panels are made from roofing-grade 3105-H24 and 3003-H24 aluminum alloy, coated with Alunar 70% PVDF fluorocarbon on both sides — a 30-year warranty against fading and chalking. Steel roofs, by contrast, require protective coatings that eventually fail, leaving the underlying iron vulnerable to corrosion that spreads and weakens the structure.
Will a metal roof keep my house cooler in summer or warmer in winter?
Metal roofs reflect solar heat rather than absorbing it, which reduces cooling load in summer — especially valuable on Kellys Corner's approximately 2881 sunshine hours annually. energy-efficient Interlock colors achieve up to 0.55 initial solar reflectance and 0.84 thermal emissivity, meaning they radiate absorbed heat efficiently rather than storing it in your attic. The reflective coating reflects the heat that asphalt absorbs and re-radiates downward. In winter, the benefit works differently: metal doesn't trap or insulate better than other materials, but the smooth surface resists ice damming by shedding water faster, reducing the freeze-thaw strain common across your 34 annual freeze-thaw days. Over a 50-year roof life, the cooling savings compound significantly.
What does Interlock's warranty actually cover, and for how long?
Interlock's Guardian Warranty is a lifetime limited, non-prorated material warranty for the original owner — meaning you're covered for rusting, rotting, splitting, cracking, and curling with no dollar limits that shrink over time. It's transferable once to the next owner, who receives 50 years of coverage from completion. Since Interlock has been manufactured since 1998 — that's 27 years of real-world performance — the warranty reflects the actual lifespan these roofs achieve. In Kellys Corner's wet climate with 1370 mm annual rainfall and 40 cm snow, asphalt roofs typically fail within 15-25 years due to UV degradation, granule loss, and moisture damage. An aluminum roof installed today will outlast multiple asphalt replacements, making it literally the last roof you buy and a significant advantage when you sell.
How much maintenance do metal roofs really need compared to asphalt or tile?
Metal roofing requires virtually no maintenance beyond occasional gutter cleaning — a significant advantage over asphalt, wood, and tile. Asphalt roofs need algae treatment, missing shingle replacement, and granule monitoring every few years; wood requires annual inspection for rot and splitting; clay or concrete tile needs mortar repointing and cracked-tile replacement. Interlock aluminum is CALGreen-verified for reduced maintenance because the material itself doesn't deteriorate chemically or physically. The 30-year Alunar coating resists chalking and fading (ASTM D4214 / D2244), so you won't see the discoloration that forces asphalt replacement. In Kellys Corner's wet environment with 1370 mm annual rainfall and 34 freeze-thaw days, this durability without upkeep translates to lower ownership costs and zero emergency repairs.
Is metal roofing worth the upfront cost if I'm staying in my home?
The answer depends on your timeline, but the lifetime value heavily favors metal. Asphalt roofs in Kellys Corner's wet, freeze-thaw climate (1370 mm rain, 40 cm snow, 34 annual F-T cycles) typically last 15-25 years and cost $8,000-$15,000 to replace, plus tear-off and disposal. Metal costs more initially but requires no replacement in your lifetime — the Guardian Warranty is non-prorated and covers material defects forever. Over 50 years, you'll replace asphalt 2-3 times, spending $24,000-$45,000 plus labor and waste fees. Metal, installed once and maintained for nearly nothing, becomes substantially cheaper. Current regional promotion: no payments and no interest until Spring 2027, or 10% off installation. If you're staying put, metal eliminates the stress and expense of a future roof emergency.
How long does metal roof installation take, and do I need to remove my old roof?
Installation typically takes 3-7 days depending on roof size and complexity — much faster than asphalt tear-off and replacement. One major advantage: Interlock's aluminum panels weigh as little as 0.41 lb/sq ft (Shingle profile) to 0.59 lb/sq ft (Tile and Shake), roughly 96% lighter than concrete or clay tile. This extraordinary light weight means most existing roofs don't require structural reinforcement, so the installer can apply underlayment and panels directly over your old asphalt without tearing it off. This saves weeks of labor, disposal fees, and weather exposure. In Kellys Corner's rainy climate with 1370 mm annual rainfall, staying covered during installation reduces water intrusion risk. Interlock Metal Roofing (PNW) Inc. has served the region since 1997 and can walk you through timing, permits, and minimizing disruption to your home.
Will a metal roof hold up to Kellys Corner's winter wind gusts?
Yes. Kellys Corner averages typical daily-max winds around 16 km/h but experiences gusts up to 99 km/h, which falls well below the 120 mph (193 km/h) wind resistance Interlock panels are warranted to achieve. The four-way interlocking design is the key: each panel locks to its neighbors on all four edges, distributing wind load across the entire roof system rather than allowing individual panels to lift or separate. This design, combined with proper fastening to spec, has proven itself from coastal salt-air installations (where wind and corrosion combine) to an Antarctic research station. If you live on an exposed hilltop or near Puget Sound, the interlocking system provides extra peace of mind during the rare extreme gust event — far superior to asphalt, which can tear or buckle under sustained wind stress.
Is metal roofing fire-safe, especially in Washington wildfire season?
Interlock metal roofing is non-combustible aluminum and achieves Class A fire classification — the highest rating available under UL standards. This matters because it means the roof itself cannot ignite, spread flames, or contribute fuel to a fire, which is critical during wildfire events or if sparks from a neighboring fire land on your roof. The ICC-ES evaluation report (ESR-1790, reissued 2025) confirms code compliance for residential and commercial applications across the IBC and IRC. While Kellys Corner isn't in the state's highest wildfire zone, the class A rating is one less variable to worry about during evacuation season or insurance discussions. Asphalt roofing, by contrast, is combustible and can contribute to fire spread; wood shakes are highly flammable. Aluminum's fire safety is permanent — it doesn't degrade over the roof's lifetime like protective treatments on other materials.
Will a metal roof help sell my Kellys Corner home?
A durable, attractive roof in a wet climate is a significant selling point because buyers immediately understand they're avoiding a costly replacement within years. Interlock's five profiles — Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile — replicate high-end architectural materials without the weight, maintenance, or vulnerability to Kellys Corner's 1370 mm annual rainfall and 34 freeze-thaw cycles. Buyers recognize metal roofing as a premium, long-term investment: the transferable Guardian Warranty (50 years to the next owner) is unusual and powerful. The roof's clean appearance, combined with zero maintenance worries and energy savings from 0.84 thermal emissivity and up to 0.55 solar reflectance, appeals directly to buyers evaluating total cost of ownership. Interlock Metal Roofing (PNW) Inc. can provide documentation of installation and warranty transfer, turning the roof into a tangible asset you're handing to the next owner.
Is a metal roof a good choice for Kellys Corner’s climate?
Yes. Kellys Corner averages about 40 cm of snow, 1370 mm of rain, roughly 34 freeze–thaw days a year, with peak wind gusts near 99 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.
