We just had a tremendous rain storm, the roof did amazing

Alsea, Oregon

5/5

From the ordering process that began in January to the actual install of the roof in November, the communication could have been better. The charcoal gray “slate” roof was installed a few days ago and we just had a tremendous rain storm, the roof did amazing. The workers who showed up were fast and professional and finished the job in 3 days. After they were done, they did a thorough site cleaning. The roof was definitely more costly than a conventional shingle roof and took some extra effort and delay to get scheduled, but we believe it was well worth it.

Interlock was easy to work with and we love the results

Beaverton, Oregon

5/5

Everything went smoothly from sales to installation. Installing a metal roof was more expensive than most other materials, but it’s going to last 40 years+ and the warrantee can be transferred to the next owner. We’re not handy and this is a huge peace of mind. We loved that this company does not subcontract and actually trains its crews on how to exclusively use their system of interlocking roof tiles. Because of this, the crew gets to work straight away, knows what their doing, and finish quickly. The things that took the longest to install were the skylights because they had to be custom made. That said, they placed a sufficient cover over the holes on the roof that held up to rain and tree debris. Interlock was easy to work with and we love the results!

Greater sense of security about the danger posed by fire

5/5

The company was very informative and efficient, and we are happy with both the aesthetic and practical results. We are also happy to have a greater sense of security about the danger posed by fire, which has been a worry because we live in a forested area far from emergency services. The workers were polite and professional and cleaned up the site pretty well. It was expensive, but we’re very satisfied with the work.

I live in a forest near the Oregon Coast. The original reason I wanted to purchase a metal roof was basically for fire prevention. Composition shingles are the worst type of roof you can have when living in a forested area; metal roofs are the best.

On September 11, 1992 I was on the island of Kauai, Hawaii when Hurricane Iniki, a Category-5 hurricane, took a direct hit. For our emergency shelter, we took refuge at the newly built Kauai Community College. We were told it had been built to hurricane standards and was safe. The college had a metal roof made of long slates stretching from the top to bottom. As the hurricane grew in strength, I watched the slate at one side of the building starting to flap…then flap more and more until it went flying into the air. Then, I watched the slate next to it do the same. This went on and on. When the eye of the hurricane went over us and everything slowed down, the people in that building rushed over to our building. For some reason our building’s roof held.

Living on the Oregon Coast we get high winds every year. When I was informed about how the Interlock roof is tied together, I was sold on purchasing that style. Now, my roof can withstand up to a 180 per hour wind gust. I also like it’s look. After it was installed I sent a photo to a friend and her reaction was: “I thought you were going to buy a metal roof.” The roof even has a slate look to it.

I used to own a business where we sent installation crews all across the country to install our multiple-run kennels. I know the importance of having a crew that knows what they are doing and are good representatives of our business. I give the Interlock installation crew an A+. They not only know what they are doing, but they are HARD WORKERS as well. On my job they went way beyond just roofing my house. They tore out the dilapidated structure around my chimney and built me a completely new one. They also added new flashing at the bottom of my roof windows, so I no longer have a problem with runoff ruining my wooden frame.

I now have a new roof that will last much longer than me. It has added value to my home and peace of mind to me. When considering a new roof, I highly recommend Interlock.

Sincerely,
Guy F.

I’ve had this roof for about 18 months now. I am very happy with it and was quite pleased with the pre-sale discussion and the actual installation. I never thought a roof was something that you would get compliments on, but I certainly get them. I figured why get a roof that would last me for 5 to 10 years when I can get one that will last virtually my lifetime? Very happy all around.

Sincerely,

Deep Charcoal Interlock Slate System | Garden Home-Whitford, Oregon

This Garden Home-Whitford homeowner had an epiphany that most people overlook: You can either buy three or four roofs in your lifetime, or you can make a single, wise investment.

The Garden Home Advantage

Garden Home-Whitford sits in that sweet spot between Portland, Tigard, and Beaverton—officially unincorporated Washington County, but with all the perks of urban living wrapped in rural charm. The Fanno Creek Trail winds through the neighborhood, connecting residents to miles of protected green space.

It’s the kind of place where houses sit on generous lots, some with half an acre or more, where the streets feel rural but you can walk to cafes and restaurants—the perfect blend of urban convenience and forest-like tranquility.
In this neighborhood of discerning homeowners, one roof stands out as a symbol of taste and quality.

Portland Metal Roofing Installation Featuring Interlock Deep Charcoal Slate Aluminum Shingles On Garden Home-Whitford Home With Professional Ridge Cap Detail And Mature Landscaping

Why This Deep Charcoal Choice Changed Everything

The Deep Charcoal Interlock Slate isn’t just a color—it’s a symbol of architectural confidence. While neighbors replace their roofs every 15-20 years (that’s three or four times in a lifetime), this homeowner chose permanence.

Here in the Pacific Northwest, roofs endure a range of harsh conditions, including rain, high winds, snow, salt air, ice, and dramatic temperature swings. These conditions create constant battles against moss, granular loss, fading, creaking, lifting, rust, and lost shingles.

Portland gets 36 inches of rain annually, with constant moisture exposure that can lead to mold, mildew, and leaks if roofing materials aren’t up to the challenge.
Traditional materials struggle. Metal roofing excels.

Portland Roofing Contractor Installation Excellence

Professional Installation Experience

“The installation crews were very nice, hard working, friendly, polite.”
You can’t fake professionalism in a customer review. When installation crews show up on time, work with precision, and treat your property with respect, it shows in every interlocked panel.

Oregon Building Code Compliance

Oregon building codes require metal roofing systems to meet stringent wind load requirements and adhere to proper flashing standards. But code compliance is just the starting point. The real test comes when Pacific Northwest storms arrive.
The 4-way interlocking design not only meets but also exceeds building standards. Each panel locks with the ones above, below, left, and right, creating a continuous barrier that sheds rain like water off a duck’s back.

Best Roof for Pacific Northwest Climate

Metal Shingles vs. Traditional Materials

Interlock Metal Roofing Systems are engineered explicitly for Oregon’s harshest seasons—built to withstand hurricane-force winds, Class IV hail, and freeze-thaw cycles that cause ice dams and roof damage.

In Portland’s wet climate, metal roofing is naturally resistant to mildew, rot, and algae—the three most significant threats to roofing longevity in our region. While other materials absorb moisture and deteriorate, aluminum shingles shed water and remain beautiful for decades.

Weather-Resistant Engineering

The science is simple: Water can’t penetrate what it can’t grip.

Portland Metal Roofing ROI and Economics

Lifetime Value Analysis

Here’s what most people don’t calculate:

  • Traditional roof replacement: Every 15-20 years
  • Average homeowner: 3-4 roof purchases in a lifetime
  • Metal roofing ROI: 85.9% according to Remodeling Magazine
  • Interlock warranty: True lifetime, 50-year transferable protection

Environmental Impact of Aluminum Shingles

Sustainability Benefits

Every year, approximately 11 million tons of asphalt shingles are disposed of in landfills. That’s the weight of roughly 2,200 Boeing 747s—every year.

Interlock systems are made from up to 95% recycled aluminum and are fully recyclable at the end of life. When your grandchildren inherit this roof (and they will), it can be completely recycled into new products.

Landfill Waste Reduction

The math: One metal roof eliminates 3-4 asphalt roof replacements from landfills. Multiply that by every home in Garden Home-Whitford, and the environmental impact becomes significant.

Solar-Ready Metal Roofing System

Cool Roof Technology

The Alunar “Cool Roof” coating system reflects heat, reducing cooling costs by up to 25%. In Portland’s increasingly warm summers, that translates to measurable utility savings.

Indoor Comfort Benefits

But more importantly, it means consistent indoor comfort. No more hot spots. No more attic overheating. Just steady, reliable performance that works with your HVAC system instead of against it.

Architectural Impact in Garden Home-Whitford

Neighborhood Aesthetics

“The most beautiful roof in the neighborhood.” This isn’t marketing copy. This is a homeowner’s honest assessment after living with their decision.

Design Integration

In Garden Home-Whitford, where architectural variety ranges from early 1900s character homes to contemporary designs, standing out requires intentionality. The Deep Charcoal Interlock Slate provides that distinctive elegance without overwhelming the home’s existing character.
It complements the natural beauty of the area—the mature trees, the Fanno Creek corridor, the rolling terrain that makes this neighborhood special.

Fire Safety for Portland Area Homes

Class A Fire Rating available

When installed with proper underlayment, Interlock Metal Roofing Systems achieve a Class A fire rating—the highest standard for residential roofing in North America.

Wildfire Protection

In a region where wildfire risk is increasing, this isn’t just about insurance discounts. It’s about protecting what matters most. While combustible materials can accelerate fire spread, metal roofing helps slow ignition and provides crucial time for fire response.

Portland Metal Roofing Contractor Recognition

The installation quality reflects the contractor’s expertise in Pacific Northwest conditions. Interlock Metal Roofing is recognized as the best metal roofing contractor in Oregon for 2024 & 2025 by Rip City Review.
This recognition isn’t purchased—it’s earned through consistent excellence in installation, customer service, and long-term performance.

The Decision That Ends All Roofing Decisions

Permanent Solution Mindset

Most homeowners spend their entire lives managing roofing problems, researching contractors, getting estimates, dealing with storm damage, and planning for replacements.
This Garden Home-Whitford homeowner chose a different path.

Transformation Results

They invested in permanence. In beauty that lasts. In engineering, that works with Pacific Northwest weather instead of fighting it.
The result: The most beautiful roof in the neighborhood. And the last roof they’ll ever need.

Top 10 Frequently Asked Questions About Portland Metal Roofing

Modern metal roofing with proper installation and underlayment is actually quieter than many people expect. The solid substrate and insulation layers significantly reduce noise transmission.

Located just outside Portland, Tigard is a greenbelt town framed by the Tualatin River and shaded by Pacific Northwest evergreens. It rains here—a lot. And when it rains, your roof becomes more than shelter. It becomes your frontline. That’s why Corey didn’t settle. He chose Interlock®.

With SmartVent, Corey’s roof doesn’t just look smart—it thinks smart, too.

Why Interlock Is the Best Roof for Tigard and the Pacific Northwest

Homes in Oregon face a unique challenge: abundant rainfall, shifting temperatures, and plenty of moss. Interlock meets those challenges with technology, design, and a guarantee you can stand under. The abundant rain can lead to leaks and moss growth; the shifting temperatures can cause traditional roofing materials to expand and contract, leading to damage. Interlock’s design and technology are specifically engineered to withstand these conditions.

Here’s why Corey made the right call:

  • Lifetime Warranty – One roof. One investment. No more re-roofing.
  • 4-Way Interlocking Panels – Built to resist wind, leaks, and time.
  • Energy Efficient & Solar Compatible – Designed for tomorrow, today.
  • Low-Maintenance Durability – No moss, no rust, no drama.
  • Bold Curb Appeal – The Black Slate profile adds luxury, not just function.
  • Sustainably Made – Crafted from recycled aluminum and made to last generations.

Corey’s home is set in one of Tigard’s serene, walkable neighborhoods—close to Cook Park, minutes from the trails of Fanno Creek, and just a short drive to downtown Portland. It’s a place where nature and neighborhood meet—and your roof should be just as smart as your lifestyle.

Because when you live in a region where it rains 155 days a year, you deserve a roof that does more than cover your home. You deserve a roof that protects your future.

 

A Roof Worth Sharing

Corey didn’t just upgrade his home; he changed how it feels to live in it. From the smooth process to the final reveal, everything about the Interlock experience delivered on its promise—and then some.

It’s not the cheapest roof. It’s the last one you’ll ever need.
Because doing it once and doing it right is what leadership looks like.

Interlock was great. The roof is beautiful and the crew was great to work with. Everyone we met with was kind, skilled and knowledgeable. Mike and Damon even helped us work with insurance some due to a tree falling on our house. Interlock made the overwhelming task of getting a full new roof a little less overwhelming, and we appreciate them so much for that.
