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

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.

Review: April 25, 2016Completion: July 30, 2015

To the Interlock Corporation, What can you say about a home improvement experience such as replacing the roof on your house? From the first contact to the completion of the project, it was the most enjoyable experience a person can have when dealing with a large commercial company. From the initial non-high pressure, very informative sales contact from a Home and Garden show to the friendly, efficient and respectful installers to the final personal contact to ensure we were satisfied with the results and that we were enjoying our new roof. The application and quality of the materials are beyond expectations. We have been enjoying the roof through the winter winds and rain, and hail of the Pacific Northwest. Everyone asks if it is noisy and tinny when it rains. We reply, “of course not! “ It is even quieter than the comp roof we just replaced. We ordered the deep charcoal grey slate. After the rain, while still wet, the roof shines and glistens like real slate. It is a welcoming sight compared to the dull comp roofs of our neighbors. Shortly after installation, there was a wedding up the road from us. We heard from a friend who attended that our roof was the hot topic of discussion since everyone had to drive by our house to reach the wedding. We get many compliments from people who drive by. The installers, while being friendly, are very proud of their workmanship, and we liked the fact that they kept referring to the roof as “their roof”. Hard-working and diligent in the task, they were attentive to every detail. The best onsite reps Interlock could ever have. They were proud of the many years of service working for the company, and that fact, too, lends itself to efficient communication and workflow. The installation happened during the summer during some of the hottest days on record. The installers measured their days, coming early, resting during the hottest times and returning during the coolness of the evenings, doing what needed to be done to get the job done. While more expensive than traditional comp roofs up front, the fact that we never have to replace the roof during our lifetime is well worth it. This house is our forever house, and the best part of our new roof is the fact that my husband will never have to climb up a ladder to clean off the moss that grows so well here in the wet but green northwest. After much investigation and consideration of other metal roofing products on the market, we highly recommend a metal roof, specifically one by Interlock.

Interlock Roofing could have kept customers informed during the project duration.

Review: August 14, 2018Completion: August 14, 2018

Interlock Roofing could have had an engineer come by and evaluate the project before the installation crew was even sent out, which may have resolved the venting problem early on.
