  • Tested to 193+ km/h (120+ mph) for severe wind performance, offering measurable uplift resistance in coastal windstorms.
  • Advanced waterproof installation methods reduce leak risk during prolonged wet seasons and heavy downpours.
  • Snow-shedding panel geometry minimizes buildup and helps prevent ice dams during freeze–thaw cycles and occasional heavy snow loads.
  • Class A fire-rated available for added protection where ember exposure and wildland interface risk exist.
  • UL 2218 Class 4 impact resistance defends against hail, falling branches, and storm debris.
  • Cool-roof reflectivity and thermal performance lower attic temperatures and reduce heat gain during summer warm spells for Carlsborg homes.
  • Profiles engineered to accept bracket-mounted photovoltaic systems without compromising roof integrity.
  • Fully recyclable aluminum supports long service life and reduced roof-replacement waste for homeowners in Carlsborg and across Clallam County.
  • Low-maintenance finish resists flaking and reduces the frequent re-roof cycles common with asphalt in high-moisture climates.

  • Designed to reduce biological buildup: smooth Alunar®-coated surfaces and controlled drainage limit moss and lichen growth in Carlsborg’s damp microclimates.
  • Marine-exposure corrosion protection preserves finish and substrate against seasonal salt spray and coastal fog affecting properties near the Strait and across Clallam County.
  • Built to manage atmospheric river events — reinforced seams and rapid runoff shedding help prevent water intrusion during prolonged rain bursts that impact Carlsborg.

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

Spec / RatingClimate / 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 4Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes.
Snow & ice performance: interlocking, shedding profileHeavy 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 systemHigh heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation.
Moss / algae resistance: smooth coated surfaceWet 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+ yearsLong-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 transferableLifetime protection + resale value: guarantees long-term material confidence and transfers to future owners.

What our customers are saying:

★★★★★
Review: June 8, 2021Completion: May 6, 2021

I am seemingly pleased with the product and the crew was great. They might be able to improve because, during the installation, they had another project so they were going back and forth between the 2 projects. Some days there was a full crew and some days they were only a couple of guys. They did a great job with the schedule they had but they didn't seem like they had the liberty to focus on one job at a time.

★★★★★
Review: March 12, 2020Completion: February 8, 2020

Thorough estimate of the project. Tripe check t measurements for accuracy. At the last minute additional costs incurred due to the inaccurate measurements taken at the time of the appointment.

★★★★★
Review: March 12, 2020Completion: January 31, 2020

None.

★★★★★
Review: July 13, 2019Completion: June 13, 2019

Lack of communication from Interlock to homeowner and installation crew about delay in materials delivery. At the end of the first day of tear off, we did not know who or when a crew would be back to finish the work, until we as home owner started making phones calls !!

★★★★★
Review: February 8, 2023Completion: January 30, 2023

They should let the homeowner know the crew's arrival time. I just remember looking out the window at 6 a.m. with his arms crossed, staring at what looked to be mean, but he was looking at the roof, and my blood ran cold because this was a different person who showed up from the previous day. My husband went outside, and we were relieved it was the installation crew, but it would be nice if they would let us know that information prior. We thought it would be loud when it rained after the project was completed, but that's definitely not the case; it's more quiet than insulated, and we have no leaks!

★★★★☆
Review: August 1, 2021Completion: June 29, 2021

If I had not been there to immediately identify problems, which were a result of the language barrier with crew on site not understanding the particular specifications of the job, it could have turned into a real disaster. Such things as not putting ventilation sheathing on the vaulted ceiling portion of the roof; then trying to put it not only on the vaulted ceiling, but other parts of the roof, where it was not required.
