Interlock® Aluminum Roofing — all-climates performance specs for Lacey, 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

Metal Roofing FAQs for Homeowners in Lacey
The following metal roofing FAQs are designed specifically for homeowners in Lacey, 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 Lacey.
How does a metal roof handle heavy snow and ice in Lacey winters?
Metal roofs shed snow and ice far more effectively than asphalt because aluminum's smooth surface prevents the adhesion that creates dangerous ice dams. Lacey receives about 40 cm of snow annually with roughly 34 freeze-thaw cycles per year—conditions that stress asphalt and wood shingles. Interlock's four-way interlocking panels are warranted to resist wind gusts up to 120 mph, so the fastening system that locks panels together also prevents snow creep and manages the weight of accumulated snow without structural strain. If you want extra control, snow guards can be added to any profile.
Does metal roofing really handle Lacey's 1,370 mm of annual rainfall without leaks?
Yes. Metal roofs are inherently leak-resistant because water sheds instantly off smooth, interlocked panels rather than pooling in granules or decomposing wood fibers. Lacey's 1,370 mm annual rainfall is heavy, but the design of four-way interlocking aluminum panels means water travels along the ridges and seams, not through them. Combined with proper underlayment and a solid deck installed by a qualified contractor, this design prevents the moisture saturation that rots asphalt and wood. Interlock's ICC-ES ESR-1790 rating confirms code compliance for weather-tightness in high-rainfall zones.
Why is aluminum better than steel roofing in the Pacific Northwest?
Aluminum cannot rust because it contains no iron—only aluminum, which naturally forms a protective oxide layer that self-heals when scratched. This matters in Lacey because winter moisture combined with 16 km/h average winds and occasional gusts to 99 km/h can create salt-air conditions that corrode steel. Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209) with a two-sided Alunar 70% PVDF fluorocarbon coating warranted 30 years against fading—protection against both moisture and UV damage through our 2,881 annual sunshine hours.
Is a metal roof worth the upfront cost compared to asphalt shingles?
Metal roofing is one roof you'll never replace—the math works over 40+ years. A typical asphalt roof lasts 15-20 years and requires complete tearoff and landfill disposal, plus installation labor twice or three times in a homeowner's tenure. Interlock carries a lifetime limited, non-prorated material warranty for the original owner, transferable to the next owner for 50 years from completion. Current financing removes that first-cost barrier: zero payments and zero interest until Spring 2027, or 10% off installation. Over Lacey's weather cycle of 1,370 mm rain, 40 cm snow, and 34 annual freeze-thaw days, you're eliminating the constant repairs asphalt demands.
How much upkeep does a metal roof need in Lacey?
Virtually none. Unlike asphalt shingles that degrade under UV (Lacey gets 2,881 sunshine hours annually) and crack during freeze-thaw cycles, or cedar shakes that split and rot in persistent moisture, aluminum panels require no seasonal maintenance, no replacement, no sealing. Heavy rain (1,370 mm/year) simply runs off; snow falls cleanly. Occasional leaf or debris clearing—the same as any roof—is all that's needed. The Alunar 70% PVDF coating is rated for 30 years against chalking and fading, so even the finish outlasts most asphalt roof lifecycles. This is why Interlock's product earned CALGreen verification for reduced maintenance burden.
Can my Lacey home support a metal roof without structural upgrades?
Yes, almost certainly—that's one of metal's greatest advantages. Interlock's lightest profile, the Shingle, weighs just 0.41 lb/sq ft; the Mediterranean Tile profile, despite its authentic appearance, weighs only 0.59 lb/sq ft—about 96% lighter than real concrete or clay tile. Because aluminum requires no structural reinforcement, Interlock installs over most existing roofs, avoiding costly tearoff and framing work. A structural engineer can confirm your specific home, but the engineering reality is that homes built to support asphalt shingles can easily handle aluminum panels. This also means faster installation and less disruption to your Lacey home during the roofing process.
How well does metal roofing stand up to Lacey's windstorms?
Interlock metal roofing is warranted to resist sustained winds up to 120 mph (193 km/h)—well above Lacey's typical gust peaks of 99 km/h. The four-way interlocking panel design is the key: each panel locks to its neighbors on all sides, creating a unified system rather than individual shingles that catch the wind and lift. This locking mechanism distributes wind load across the entire roof assembly, preventing the flutter and uplift that commonly damage asphalt and wood shakes. Installation to specification—proper fastening into solid deck—locks in this warranty protection. During Lacey's windier months, you're not wondering if your roof is about to fail.
Can I get a metal roof that actually looks like slate, cedar shake, or tile?
Interlock offers five authentic profiles: Slate, Cedar Shingle, Shake, Standing Seam, and Mediterranean Tile. Each is designed to replicate traditional materials in appearance while delivering metal's durability. On a Lacey home subject to 40 cm annual snowfall and 1,370 mm rain, you get the visual warmth of cedar or slate without the splitting, rotting, or continuous maintenance those materials demand. The profiles are available in multiple colors to suit any architectural style. Standing Seam appeals to modern homes; Slate and Shake suit craftsman and cottage aesthetics; Mediterranean Tile works with contemporary and transitional designs. Your home's appearance doesn't change—only its performance improves.
Will a metal roof help reduce cooling costs in summer?
Yes. energy-efficient Interlock colors reflect solar heat rather than absorbing it the way dark asphalt does. Thermal emissivity reaches 0.84 and solar reflectance up to 0.55 (Aged Copper Penny)—meaning summer sun bounces away instead of heating your attic and living spaces. Lacey's 2,881 annual sunshine hours make this meaningful even in the Pacific Northwest climate. The Cool Roof Rating Council rates these reflective properties independently, so the energy savings are real and measurable, not marketing claims. Combined with reduced heat transfer through lighter-colored aluminum, you'll see lower AC costs during Lacey's warmest months and reduced cooling load year-round.
How long does metal roof installation take and can it be done over my existing roof?
Installation timelines vary with roof complexity and weather, but metal roofing is faster than asphalt replacement because there's no tearoff—Interlock installs directly over your existing roof in most cases. This eliminates weeks of debris removal and disposal. A typical residential roof takes 3-7 working days depending on size and profile. Working over an existing roof in Lacey is practical because the lightweight aluminum (0.41–0.59 lb/sq ft) doesn't stress your structure. Your installer, Interlock Metal Roofing (PNW) Inc., has served the region since 1997 and knows local conditions—moisture, wind, rainfall patterns. They'll assess whether tearoff is necessary and give you realistic scheduling around Lacey's wetter months.
Is a metal roof a good choice for Lacey’s climate?
Yes. Lacey 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.
