Interlock® Aluminum Roofing — all-climates performance specs for Gaston, 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. |

WE LOVE THE ROOF! The look! The fact that we WON’T reroof again.We hope this helps you on your decision to go with Interlock. Positive: Quality, Professionalism, Value Services: Roof installation
I looked into replacing my roof and found that with modern composite shingles I will end end replacing it numerous times in my lifetime. With Interlock it's one and done. The roof I got was red aluminum in a slate style and it looks great; best roof in my neighborhood, hands down. In fact it's fun to see cars driving by and notice the driver staring at the new roof. Also, I've received numerous compliments from passersby about how great the roof looks. Other points are that the install was quick and skillful and needless to say, I have no leaks. Positive, Professionalism, Services: Roof installation
I was initially apprehensive about the higher upfront cost of Interlock when compared to a basic composite shingle replacement, but three factors swayed me to give Interlock my business. First, the engineering behind the product is quite impressive. By that, I mean the way the panels interlock to form a tight, durable roof. Second, the roof looks great and will look the same for decades. Third, it’s a more environmentally sound solution by keeping my home cooler in the summer and also by being the last roof replacement the house will need. I have to say the installation crew was top-notch. They completed the job from tear-off to done in just over two days and left the gutters and yard cleaner than they found them. Admittedly my roof is small and fairly simple but to knock it out in two days during the triple-digit heat earned them my respect. All in all, I’d say I’m very happy with my new roof and the overall experience of working with Interlock.
Please consider this my letter of testimony regarding the installation of my beautiful Musket Grey Slate roof! From the beginning of this “roof project”, all of my conversations with Meg and Claudette were friendly and my questions were answered by these pleasant and knowledgeable ladies. Since I had already seen a presentation with a neighbor, Mike Rasmussen was able to save us both some time as I was very ready to get my leaky roof replaced! He thoroughly explained how the aluminum fits together and assured me the trained installers really did know what they were doing! Rolland called to let me know when he would be delivering the materials. He was right on time – even with snow and icy roads to contend with! He very neatly placed boxed materials next to the garage and then covered everything with a tarp to keep it dry. I was concerned with his and the installers’ safety during those unusual winter weather conditions but both Rolland and Peter seemed to take it in stride. Peter was very efficient and explained how things worked and answered my questions that I didn’t know I had until I watched how fast yet carefully he worked. Mike was right – Peter was quick and there was very little wasted material when he had completed everything! As it turned out, Peter was the only installer and he wasted NO TIME removing the chimney, getting my skylight replaced and the roof was done in only two days!! It was unusually COLD in Oregon those days; January 7th and 8th. He worked well into the dark evening hours on both nights, which I thought was above and beyond the call of duty. He carefully cleaned up after himself before he left. As you see, I am very impressed with my new roof. At one point, I was concerned that the aluminum may be “noisy”, however, with the amount of hard rain we have had, there is no more noise than there was with my old shingle roof. Again, I am impressed. My son is thrilled that he will never have to get up and toss laundry soap around on the roof to kill the moss! Just today, a gentleman stopped to chat about my roof as he’d noticed the sign in my yard. I happened to be outside for a few minutes and was happy to share my very pleasant experience with him. Neighbors have stopped to look at the sign and check out the roof on their walks. Enclosed are pictures of my “roof project”. Strangers would not know there ever was a chimney on the house. Peter was very careful removing the bricks which I appreciated since the new Leaf Guard system was recently installed. I thank you all for your help with updating my house. Please feel free to call me at 503-xxx-xxxx if you would like further comments.
I absolutely love my new roof. Damon my sales rep was fantastic and the installers were the height of professionalism3/8/2021So after the snow and ice storm last month my metal roof still looks great and for the first time in 22 years I didn't have to worry about losing shingles in the storm. Positive Responsiveness, Punctuality, Quality, Professionalism, Value
Fast response and excellent work. The technician drop by within couple of days, found the cause, and provided quote. The price was reasonable for the work scope. They were able to secure the work slot as soon as the raining season was over and kept me informed on the schedule. In addition, they inspected remaining roof as well. Note: the leak was due to gutter pulling the corner flashing. The 10+ year Interlock roof tile remained good.
Prompt, ongoing communication from bid to follow up after completion. Install crew was professional and polite. We had an involved tear-off and they spread tarps overnight in case of dew. Finished job looks great.
Roof looks amazing, install team was very professional kept the area very clean every day.
Interlock roof is the best. That is 12-15 years after we first got it. Perfect condition still! Never a second thought. Thanks
Interlock handled our roofing project with skill and expertise. Many other local roofers ran away from even bidding the job due to the complexity of our roof line. The result is exquisite and I'm hopeful any further service needed over the years will go just as smoothly as the install did. Positive, Quality, Value, Services: Roof installation
They installed an amazing IB membrane that makes the house look great. They suggested this product for my price range and expectations for a lifetime roof!

Metal Roofing FAQs for Homeowners in Gaston
The following metal roofing FAQs are designed specifically for homeowners in Gaston, 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 Gaston.
Will a metal roof rust in Oregon's wet climate?
No — aluminum cannot rust because it contains no iron. Gaston receives about 1208 mm of rain annually, but aluminum's oxide layer actually self-heals when scratched, making it ideal for wet conditions. The Alunar 70% PVDF coating is applied to both sides of every panel and carries a 30-year warranty against chalking and fading under ASTM testing. This two-layer protection is why Interlock panels have been installed in coastal salt-air homes and even an Antarctic research station since 1998.
Does metal roofing hold up to hail in Washington County?
Yes — Interlock panels carry 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 plus non-combustibility can make insurers willing to offer discounts. Gaston's freeze-thaw cycles (about 37 days per year) and occasional wind gusts to 120 km/h create conditions where impact resistance matters; Class 4 aluminum outperforms asphalt and cedar shake in those scenarios. Ask your insurer about premium reductions when you switch.
Can a metal roof handle Oregon wind gusts?
Gaston experiences gusts up to 120 km/h, and Interlock's four-way interlocking panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to spec. The interlocking design transfers wind load across the entire system rather than stressing individual fasteners. With about 16 km/h typical daily winds, you're well within the safe margin — and you'll have documented warranty coverage for the severe events. That certainty is one reason contractors in the PNW have trusted this design since 1997.
Won't heavy rain leak through metal roofing seams?
Heavy rainfall doesn't overwhelm metal roofing if the deck is solid and the underlayment is installed correctly — water sheds faster on a smooth metal surface than it soaks into asphalt. Gaston's 1208 mm annual rainfall drains quickly through the four-way interlocking seams when the panels are aligned and fastened per ICC-ES ESR-1790 specifications. The real protection is proper installation: a capable local contractor like Interlock Metal Roofing (PNW), serving the region since 1997, will ensure water flow and seal every penetration. Metal itself doesn't leak; installation does.
Do metal roofs really lower cooling costs?
energy-efficient Interlock colors reflect heat instead of absorbing it — some achieve initial solar reflectance up to 0.55 and thermal emissivity of 0.84. Gaston averages about 3033 sunshine hours yearly, so reflective coatings compound savings over time. A metal roof won't turn a winter-heavy climate into an air-conditioning savings showpiece, but it eliminates the summer heat absorption that dark asphalt creates, keeping your attic cooler and reducing cooling load. The long-term benefit is energy stability in a temperate region with real sunshine.
Do I need to reinforce my roof structure for metal roofing?
No — aluminum's weight is extraordinary. The Slate profile installs at about 0.41 lb/sq ft, and the Mediterranean Tile at 0.59 lb/sq ft, making it roughly 96% lighter than concrete or clay tile. Because Interlock panels weigh so little, they install over most existing roofs without structural reinforcement, cutting labor and cost. Gaston homes built for traditional asphalt can easily carry aluminum. That lightweight advantage also means easier installation in snow and wind conditions typical of Washington County.
What's the actual warranty on a metal roof?
Interlock offers The Guardian — a lifetime limited, non-prorated material warranty for the original owner covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. That warranty is also one-time transferable, giving the next owner 50 years from completion. In a region with 37 freeze-thaw days per year and 29 cm of annual snow, non-prorated coverage matters: you're protected against splitting and cracking from thermal cycling. This is genuinely the last roof most homeowners buy.
How much maintenance does a metal roof need compared to asphalt or wood?
Metal requires far less maintenance than asphalt or cedar. There's no seasonal granule loss, no moss growth from standing water, and no wood splitting from Gaston's 37 annual freeze-thaw cycles. Asphalt shingles degrade under UV and moisture; aluminum's Alunar coating is warranted for 30 years against chalking and fading. Periodic gutter cleaning and inspection of flashing is all you need. CALGreen verification confirms Interlock meets reduced-maintenance standards. Over a 50-year lifespan, the time and material you save is substantial.
Is metal roofing actually better for the environment?
Aluminum is approximately 95% recyclable and ends the asphalt tear-off-to-landfill cycle that repeats every 15–25 years. When your Interlock roof eventually reaches end-of-life, the panels go back into the material stream rather than a dump. Gaston's 1208 mm annual rainfall and 29 cm of snow create conditions where durability directly reduces environmental impact — a 50-year roof generates far fewer replacement cycles than asphalt. Choosing aluminum is a practical choice for homeowners who want their roofing decision to align with waste reduction.
How long does it take to install a metal roof, and can you install over my existing roof?
Yes, Interlock panels install over most existing roofs thanks to their lightweight design — typically no tearoff required. Installation timeline depends on roof size and weather, but a skilled crew can work steadily through Gaston's 1208 mm annual rainfall if the existing deck is sound. The local installer, Interlock Metal Roofing (PNW), has 27+ years of regional experience and currently offers no payments and no interest until Spring 2027 or 10% off installation. Getting a site-specific timeline requires a walk-through, but over-roof installation is one reason metal roofs save money upfront.
