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

Review: November 30, 2002Completion: July 8, 2004

My wife and I want to express our complete satisfaction with the "Aged Copper" roof your firm installed on our "Barn-house" and gazebo. The two roofs have a high quality appearance and they enhance the looks of the property. We are looking forward to many years of satisfaction. We are now planning to re-paint the house with a color to better blend with the roof. The work performed by your installers was outstanding. They were friendly and very professional. They worked efficiently and energetically, and it was obvious they had the skills to do the job. Thank you for being such an excellent firm.

★★★★★
Review: February 19, 2016Completion: December 8, 2015

We had the Interlock Roof installed in November of 2015 since then we have had some torrential rains and winds exceeding 50 mph. The roof has weathered the storms and is just as sound as the day the workers completed the installation. We are extremely pleased with the roof and the appearance of the roof. We are also very pleased that we chose the Interlock roof, both for the appearance and the wear ability of the product. It is a huge relief for us to know that this is the final roof we will ever have to put on our house and that the product is backed by a lifetime warranty. Your roofing specialists that installed the roof were very professional, considerate, and thorough in their work.

★★★★★
Review: April 9, 2007Completion: April 12, 2007

We are DELIGHTED with our new roof! The day after it was completed, we had a windstorm. It was so wonderful to wake up knowing there would be no shingles in the yard or loose shingles on the roof. And it is BEAUTIFUL!

★★★★★
Review: November 19, 2019Completion: October 14, 2019

Interlock Roofing could have improved follow through with customer service. We love the roof, and other than the small hiccup with the installation date, everything went well.

★★★★★
Review: March 25, 2016Completion: March 25, 2016

Trying to justify the high cost. Not sure of the Quality vs cost ratio

★★★★★
Review: August 31, 2009Completion: May 7, 2009

“No Worries”, may be an “in” thing to say now days, but for us it is a reality for the next 50 years! This summer, we didn’t worry about the bottle rockets landing on our roof. This fall, we won’t worry about the shingles blowing off in the next 60 plus mile an hour wind. This winter we won’t worry about the snow. And in the spring, we won’t worry about the moss growing on on our roof. If you are thinking you want a roof like ours, no worries about the salesman pressuring into something you don’t want. They were very professional and nice. Everything they promised was delivered exactly as they promised. You will also have no worries when it comes to the installation, as they too were very professional and left the yard just as they had found it. No worries also when it comes to our carbon footprint, as our existing roof is still on our roof and not in a landfill and when the day comes to replace this roof it is recyclable. They really should rename the Interlock Roofing to No Worries Roofing. “No Worries” in Bremerton

Review: June 3, 2021Completion: April 30, 2021

The end of the project could be more definitive. I'm still waiting for them to come take pictures of the roof. I don't like the open end of that because they haven't taken the photos yet. We are super happy with the roof. It is gorgeous! We are so excited to have it. My only complaint, is that I want the photos done.

★★★★★
Review: September 1, 2020Completion: September 1, 2020

They did exactly what they were supposed to do, there isn't much to improve on.

★★★★★
Review: October 25, 2019Completion: September 26, 2019

Interlock Roofing could improve on their initial communication process, and details of the project could be explained in better detail.

★★★★★
Review: October 18, 2019Completion: October 18, 2019

I ran the numbers and I'm prioritizing this roof system. It costs more but it's worth it.

★★★★★
Review: November 30, 2024Completion: October 29, 2024

I think they could have better communication and better interactions with the homeowners about problem areas. I didn't get a notification that they removed the lean on the house.

★★★★★
Review: March 24, 2020Completion: February 5, 2020

I think better communication at the beginning of the project and let me know when it would start would have made it much better. It would have prevented an issue at the beginning of the project. It is never good to start a project with an issue. I think someone should have notified me ahead of the time when they were coming or when to expect the delivery of material. The crew got here and they had to call for more material and they let me know. The head of the crew was very informative and let us know what was happening. He was very good.
