Interlock® Aluminum Roofing — all-climates performance specs for Conway, 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:
There were no areas, they actually moved up the date, which was a plus. We were very happy with our roof. We are a little sad to see that roof on our old house because we now live in a new house that also needs a roof. When we go to replace this one, we will defiantly call them and use them again.
I don't wish to be contacted by anybody from Interlock again.
FOLLOWUP AFTER THE PROJECT IS COMPLETED. A PHONE CALL TO SEE IF WE WERE SATISFIED WOULD HAVE BEEN APPRECIATED.
I am happy with the whole thing.
I installed a new metal interlock roof on my home in Anacortes. A big part of the cost was removing the existing concrete tiles from my roof which are a challenge. From the beginning working with sales, Paul and Ross was a pleasure...very responsive and professional. The installion crew and project managers, Tony and Patrick were terrific to work with. There were a few complications due to the existing roof but the Interlock team worked with me to resolve those issues. The crew were punctual and the installation proceeded on schedule. The cleanup was immaculate. My main goal was NOT to see any further leaking in my lifetime and hopefully that will be achieved. The roof looks great. If you are in the market for a metal roof, I would certainly recommend Interlock.
They gave us a beautiful roof, for which we get many compliments. The project manager should be fired. I had to rent an outdoor bathroom for them. I wasn't going to let 10 people in my house to use the bathroom during covid.
I already discussed the issues I had on the first day. I think the cleanup process could have been improved. It was clear that the crew worked very long hours without taking any noticable breaks. They also didn't leave the property for any restroom breaks.
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!

Metal Roofing FAQs for Homeowners in Conway
The following metal roofing FAQs are designed specifically for homeowners in Conway, 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 Conway.
Will a metal roof handle Skagit County's freeze-thaw cycles?
Yes — aluminum's oxide layer actually strengthens through freeze-thaw exposure rather than degrading. Conway experiences about 47 freeze-thaw days annually, a condition that splits wood shakes and cracks asphalt within years. Aluminum expands and contracts uniformly without trapping moisture, so repeated freezing and thawing won't compromise the panels or their four-way interlocking seams. The 3105-H24 and 3003-H24 alloy rated to ASTM B209 has been installed from coastal regions through Antarctic research stations—environments far harsher than your typical winter.
How does a metal roof perform under heavy snow loads?
Metal roofing sheds snow reliably because of its smooth, slick surface and the way snow releases naturally as the roof expands in sun. With about 43 centimeters of annual snow in Conway, that consistent shedding prevents the ice-dam buildup that traps water under asphalt shingles. The Interlock panels weigh just 0.41 to 0.59 pounds per square foot depending on profile—so light that accumulated snow is never a structural stress. Optional snow guards keep snow from sliding unpredictably if that's a concern for your property layout.
Does metal roofing actually prevent leaks in a rainy climate like Conway?
The four-way interlocking design creates a continuous water barrier that handles Skagit County's 1,312 millimeters of annual rainfall without fail. Water moves downslope through overlapped seams rather than pooling or penetrating panel edges. Combined with an ICC-ES-evaluated installation (ESR-1790) over solid deck and quality underlayment, the system performs identically to asphalt in rain tests—but without the degradation asphalt suffers after 15–20 years of constant wet exposure. Gutters and flashing still matter, but the panels themselves won't leak.
Why doesn't aluminum rust like steel roofing does?
Aluminum naturally cannot rust because it contains no iron; rust requires iron oxide. Instead, aluminum develops a self-healing oxide layer that seals the surface instantly when scratched. On top of that, Interlock applies Alunar 70% PVDF fluorocarbon coating to both sides of every panel—extra protection against salt air and coastal humidity. This dual defense is why the coating carries a 30-year warranty against chalking and fading (ASTM D4214/D2244 tested). Homes in Skagit County's damp maritime climate benefit directly: no red staining, no structural weakening, no surprise repair bills.
Can metal roofing survive Skagit County's wind gusts?
Absolutely. Conway's typical gusts reach about 100 kilometers per hour, well within Interlock's warranted resistance to 120 mph (193 km/h) winds when installed to specification. The four-way interlocking panels lock together on all edges—top, bottom, left, and right—so wind pressure cannot separate them or curl their edges. This continuous mechanical grip outperforms asphalt shingles, which catch wind like sails and tear from the edges inward. With wind events common in your region, the locked-panel system delivers genuine peace of mind that single-fastened shingles simply cannot match.
Do I need to reinforce my roof structure for metal roofing?
No structural reinforcement needed. Interlock's Mediterranean Tile profile weighs just 0.59 pounds per square foot—about 96% lighter than concrete or clay tile—while the Cedar Shingle comes in at 0.41 pounds per square foot. Most existing roof structures that safely carry asphalt (which weighs 2–3 times more) have plenty of capacity. In fact, Interlock panels install directly over your existing roof in most cases, avoiding the tear-off mess and cost entirely. This lightweight advantage matters in Skagit County's rainy climate, where water-saturated wood sheathing becomes heavy; aluminum eliminates that hidden load concern.
What's the hail rating, and could it lower my insurance?
Interlock holds the highest hail impact rating available: UL 2218 Class 4, which means it resists hailstones up to 1.5 inches—and the warranty even covers perforation from impacts in that range. While Skagit County doesn't experience frequent severe hail, the Class 4 rating reflects extraordinary durability that some insurers recognize and reward with discounts. Call your agent with the UL 2218 Class 4 specification; they may offer savings that partially offset the roof cost. More importantly, you'll own a roof that genuinely resists impact damage that would dent, crack, or puncture asphalt or tile.
Is a metal roof worth the upfront cost compared to asphalt?
Metal roofing costs more initially, but asphalt is a recurring expense. A typical asphalt roof lasts 15–20 years in Skagit County's wet, freeze-thaw climate; you'll replace it twice while Interlock's lifetime limited warranty (non-prorated for the original owner, transferable for 50 years to the next owner) spans decades. Factor in tear-off labor, landfill fees, and rising replacement costs, and the second or third asphalt cycle often exceeds the metal roof's initial price. Plus, Interlock's current promotion offers no payments and no interest until Spring 2027 or 10% off installation—terms that reset the math firmly in metal's favor.
How much maintenance does a metal roof really need?
Far less than asphalt or wood. Asphalt shingles need regular inspection for granule loss and curling; wood shakes crack and rot in Skagit County's 1,312 millimeters of annual rainfall; tile requires re-pointing of mortar joints. Interlock aluminum simply doesn't degrade that way. You'll rinse gutters, trim overhanging branches, and check flashing annually—the same tasks any roof requires. The CALGreen-verified product confirms reduced maintenance expectations. No algae growth, no splitting, no seasonal repairs. The Alunar coating handles weathering without intervention, so you're truly buying the last roof you need to think about.
Is metal roofing really more sustainable than asphalt?
Yes. Interlock panels are approximately 95% recyclable aluminum, so when the day comes (decades from now), the material returns to the recycling stream as raw feedstock. Asphalt shingles, by contrast, end up in landfills—your tear-off alone generates a multi-ton waste event every 15–20 years in Skagit County's climate. Over a 50-year span, metal roofing eliminates three to four tear-off-to-landfill cycles. The aluminum itself requires less energy to recycle than to produce from ore, so the environmental math improves with time. Choosing metal isn't just longer-lasting; it's a genuine break from the asphalt-replace-asphalt treadmill.
Is a metal roof a good choice for Conway’s climate?
Yes. Conway averages about 43 cm of snow, 1312 mm of rain, roughly 47 freeze–thaw days a year, with peak wind gusts near 100 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.
