Interlock® Aluminum Roofing — all-climates performance specs for Fort Stevens, Oregon
| 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:
We have only had our new roof for 3 months & we are so far satisfied with the quality of the materials. However, nearly every other part of our experience was less than satisfactory. We cannot risk our credibility to encourage someone we know to pay a premium price for this experience. Despite our request, we still have not received any documentation regarding our roof warranty nor information about future care/maintenance or repairs of the roof. And since our experience has been less than satisfying, we dread having to ever contact Interlock in the future for any assistance about the roof.
I have already recommended Interlock roofing and will continue to do so as I don’t think you could get a better roof for the money spent. The start time delays were the only issue for the whole job.
I would have liked them to use their own equipment instead of using my new ladder. Homeowner works on an oil tanker and will be away from the home for the next 2 months. He was there for the start of the project but not the completion. Wife signed off on the project with the contingency that he is satisfied with it when he finally come back to look at it.
We appreciate their understanding in terminating the contract.
Interlock Roofing could improve on informing me of outlying factors while they were completing the roof and they don't return calls. The roof placed on our home by Interlock Roofing leaks because the siding was bad on one side of the roof and Interlock Roofing did not inform me while they were replacing the roof. When I reached out to Interlock Roofing, they stated the siding was good when they placed the roof and stated they would replace the siding but they will no longer answer my phone calls and we still have a leaking roof.

Metal Roofing FAQs for Homeowners in Fort Stevens
The following metal roofing FAQs are designed specifically for homeowners in Fort Stevens, Oregon. 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 Fort Stevens.
How does a metal roof handle Fort Stevens' heavy snow and freeze-thaw cycles?
Metal roofs shed snow and ice far more effectively than asphalt because their smooth, hard surface prevents accumulation and ice dam formation. Fort Stevens averages about 37 cm of snow annually and experiences roughly 10 freeze-thaw days per year—conditions that crack and curl traditional shingles. Interlock's four-way interlocking aluminum panels remain rigid in those temperature swings, and the lightweight design (Shingle profile at 0.41 lb/sq ft) means no structural stress from snow load. You can add snow guards if desired, but the roof's natural shedding typically prevents problematic buildup.
Does metal roofing really handle Fort Stevens' 1,800+ mm of annual rainfall without leaking?
Yes—metal roofing excels in the Pacific Northwest's wet climate because water simply runs off the hard, sealed surface rather than being absorbed like asphalt. Fort Stevens receives approximately 1,839 mm of rain yearly, and Interlock's four-way interlocking panels create a unified, leak-resistant envelope with no gaps for water penetration. The panels are installed over a solid deck and underlayment, meeting ICC-ES ESR-1790 standards for the IBC and IRC. Proper flashing at valleys and edges completes the system; once installed to spec, leaking is virtually eliminated.
Will an aluminum metal roof stay in place during Fort Stevens' coastal wind gusts?
Absolutely. Fort Stevens experiences mean daily winds around 20 km/h with gusts reaching 147 km/h—and Interlock panels are engineered for exactly these conditions. The four-way interlocking design locks each panel to its neighbors in all directions, and the system is warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. This mechanical interlock, combined with the lightweight aluminum construction, prevents uplift and flutter that can compromise heavier roofing materials. Your roof remains secure through the Pacific Northwest's most aggressive wind events.
Does coastal salt air corrode aluminum roofing in Oregon?
No—aluminum cannot rust because it contains no iron. Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209), which develops a natural oxide layer that self-heals when scratched, providing inherent protection. The Alunar 70% PVDF fluorocarbon finish is applied to both sides of every panel and is warranted 30 years against chalking and fading (ASTM D4214/D2244 measured), giving extra defense in salt-air environments like Fort Stevens. Many Interlock installations operate successfully in coastal salt-air homes; the combination of non-ferrous aluminum and dual-coat protection means your roof won't degrade from ocean exposure.
What's the hail rating on metal roofing, and can it help with insurance in Oregon?
Interlock achieves UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty even covers perforation from hailstones up to 1.5 inches. While Fort Stevens' climate data doesn't indicate frequent hail, the Class 4 rating demonstrates the panel's exceptional toughness under impact, which some insurers recognize when underwriting. The non-combustible aluminum (Class A fire available) and extreme durability can qualify your home for premium discounts; contact your agent with the UL 2218 Class 4 certification to explore savings. This impact resistance also protects against tree limbs and debris common in the region's windy conditions.
How long does a metal roof really last, and what does the warranty actually cover?
Your roof will outlast multiple asphalt replacements. 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. The next owner receives 50 years of coverage from completion—a testament to aluminum's true longevity. With approximately 2,897 annual sunshine hours and about 37 cm of snow per year, Fort Stevens' weather profile is well within the operating range of aluminum roofing installed since 1998 (from coastal salt-air homes to an Antarctic research station). You're not replacing this roof in 20 years; you're installing your last one.
Can my Fort Stevens house structure support a metal roof without costly reinforcement?
Yes—aluminum's extreme lightness eliminates the need for structural upgrades. The Interlock Tile profile installs at 0.59 lb/sq ft, making it roughly 96% lighter than concrete or clay tile, so no foundation, framing, or support beam modifications are required. You can install Interlock over most existing roofs without tearing off the old one, saving thousands in labor and disposal. The Shake profile weighs only 0.58 lb/sq ft, and even the heavier Standing Seam remains negligible compared to traditional roofing materials. For a 2,000 sq ft roof in Fort Stevens, the total weight difference versus stone tile is measured in tons—all savings, no structural cost.
Does metal roofing reduce cooling costs in a cloudy climate like Fort Stevens'?
Yes, even in the Pacific Northwest. Interlock offers energy-efficient colors with initial solar reflectance up to 0.55 (Aged Copper Penny) and thermal emissivity of 0.84, rated by the Cool Roof Rating Council. While Fort Stevens averages 2,897 sunshine hours yearly—less than sunnier regions—reflective coatings still reduce heat absorption and lower cooling demand during warmer months and the occasional sunny spell. In spring and fall, when heating and cooling costs fluctuate, the reflective finish moderates interior temperature swings. Over decades, this efficiency compounds into measurable savings, complementing the roof's lifetime durability and reducing your home's carbon footprint.
How much maintenance does a metal roof need compared to asphalt or wood shakes?
Metal roofing requires virtually no maintenance. Asphalt shingles demand regular inspection, granule replacement, and eventual tear-off; wood shakes require annual cleaning and re-staining to resist rot and insect damage. Interlock aluminum panels resist rot, insects, mold, and UV fading for 30 years of coating warranty (ASTM-measured standards). Fort Stevens' 1,839 mm annual rainfall and roughly 10 freeze-thaw cycles won't degrade the aluminum or its fluorocarbon finish. Simply rinse away coastal salt spray or debris during spring cleaning—that's it. No re-coating, no repairs from weather damage, no seasonal maintenance. This simplicity, combined with CALGreen verification for reduced maintenance, means decades of peace of mind and real time savings.
Is a metal roof really worth the upfront cost, or should I stick with asphalt?
Metal roofing is worth every penny when you factor in the full lifecycle. Asphalt typically lasts 15–20 years and requires replacement, tear-off, and landfill disposal—repeat that cycle multiple times over 50+ years. Interlock's lifetime non-prorated warranty for the original owner, plus 50-year transferability to the next, means you install it once. The Alunar coating lasts 30 years against chalking and fading, and the panels resist the exact conditions Fort Stevens throws at it: 1,839 mm rain, coastal salt, wind gusts to 147 km/h, and freeze-thaw cycles. Current promotion: no payments and no interest until Spring 2027 or 10% off installation. Over the life of your home, metal roofing eliminates multiple replacement cycles, disposal fees, and the certainty of future re-roofing—transforming a major liability into a one-time asset.
Is a metal roof a good choice for Fort Stevens’s climate?
Yes. Fort Stevens averages about 37 cm of snow, 1839 mm of rain, roughly 10 freeze–thaw days a year, with peak wind gusts near 147 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.
