This is 2 years later and our roof still looks brand new, and we love it

5/5

For anyone considering purchasing an Interlock Roof:

Please know Dave and I purchased a roof for our home from Interlock in July 2014.

The roof was installed April 2015. The roof is absolutely beautiful, the installers were amazing (our home is an arch rib so is almost all roof) with their agility and ability as they worked and walked on our roof like monkeys.

Everyone from our salesman Derek the office gal Shauna to Janar and his crew was very professional and experienced in their field. Please feel free to show our roof to anyone interested in same. We would highly recommend this product and your installers to anyone we are so very happy we went with Interlock.

This is 2 years later and our roof still looks brand new, and we love it.

We had a small issue of rusty nails in the flashing and an issue with moisture in Feb 2017 with the unusual weather of warmth and cold. Within a day of contacting Interlock, an inspector was sent to assess and address the matter promptly.

Anyone who visits and sees our roof is impressed with the absolutely beautiful look of it.We previously had a cedar shingle roof and thought this metal roof might be noisy when it rained but it is quieter than the shingles were.

Thank you Interlock, Derek, Shauna, and crew for the wonderful Quality and beautiful product; we are proud and grateful to be covered by Interlock.

Sincerely,
Dave and Claudette Ashmore

The service was exceptional

Milwaukee, Wisconsin

5/5

Our experience having our Interlock roof installed was exceptional. It was installed during the hottest days of the year, and none of our neighbors could believe the installers were working so hard during the hot, muggy weather. They finished several days ahead of schedule, and left the yard clean and neat, even after a complete tear-off of three layers of roofing.

One day during the installation, we had a rain storm, and the installers all took shelter in their vehicles. I noticed that we had a leak in a spot that had clearly had leaks before we bought the house. When I pointed it out to the installers, they went up the ladder in the pouring rain, found the cause of the problem (which, again, was a pre-existing problem, not one due to the Interlock installation) and fixed it on the spot. The service was exceptional.

Sincerely,

It keeps our house much cooler in the summer than the asphalt roof we used to have

Kewaskum, Wisconsin

5/5

We purchased our roof in 2009 and as you can see from the pictures taken in May of 2017 our roof looks as new as the day we bought it. Here are the things we have noticed most about our Interlock Lifetime Roof over the last 8 years.

  • It keeps our house much cooler in the summer than the asphalt roof we used to have.
  • It really sheds snow, and the snow guards work great. We never need to use a snow rake.
  • We love the durability and the curb appeal.
  • Greg Weber our representative, who we were enthused to learn, is still with the company.
    When we saw him in 2009 he laid out all the variables in a professional way and our Interlock Roof has lived up to all of our expectations and promises he made.
    All companies promise results, service, and quality. Interlock delivers.

Dear Interlock Lifetime Roofing Systems,

The install was terrific. Jessie and his crew were very nice, polite, clean and work together like a well oiled machine. If I was to have work done on my home for any type of project, this is the team I would recommend and would want to work on my house. Greg Weber, my sales representative, answered all my questions, set the proper expectations, and over delivered in every aspect. 

We had a major rainstorm shortly after the installation and we noticed no difference in sound at all. Our Interlock roof is the talk of the neighborhood.

Worth every penny as you never have to re-shingle again

Burlington, Wisconsin

5/5

We have been do-it-yourselfer homeowners our whole lives. We are very handy and capable when it comes to home improvements and appreciate craftsmanship and quality.

And that’s what Interlock Lifetime Roofing Systems provided us with our roof. Craftsmanship and quality. Plus, durability, beauty, and experience from a company that manufactures and certify install its own product. That is something, a company that makes its own product, that was very important to us, and no other company in our market offered that, except Interlock.

Another thing that was important was we didn’t want to have to deal with rust because many steel metal roofs look good new but look old and hideous down the road because of fading and rusting. Interlock is aluminum. So, it won’t rust and it achieves and exceeds the highest rating of hail resistance. So, it’s like we said earlier – super durable!

Jessie and his crew were super, and hard working. We were amazed by their work ethic. That’s something that’s becoming rare nowadays.

Also, we were told by a competitor that Greg Weber and Interlock would be high pressure. That was the furthest thing from the truth. Greg was polite, personable, knowledgeable, and helped us sift through the “lesser quality, cheaper installation, sales gimmicky and overly aggressive” competitors. He provided us with a detailed range of the competition by laying out all the variables so we could make an intelligent comparison and decision. Greg helped save us a lot of time from all the other companies in our market selling what everyone else is selling, or just selling stuff, and making promises they can’t keep.

All the asphalt guys want you to believe that their products will last, and all the steel companies want you to believe their products won’t rust, and everybody knows…That’s Just Not True! Interlock has proven itself for over 4 decades. That’s Impressive. That’s why we went with them, Jessie, and Greg.

Our Interlock roof is very silent

Franklin, Wisconsin

5/5

Installation was super smooth. Every installer was courteous and professional. We get lots of compliments and people stop by all the time to admire it. One of the biggest misconceptions about metal roofing is people think it’s loud. Our Interlock roof is very silent. The only way I know if it’s raining is if I look out a window. Also, the snow just slides off. We are also in a wind tunnel area and we have never lost an Interlock shingle, and we have had the roof for many years. 

We were so pleased with our Interlock roof that we put the same roof on our lake home in northern Wisconsin. We get a lot more snow up there and the Interlock’s snow shedding performance capabilities are second to none on that roof, too!

We noticed over the years is how much cooler our home office upstairs is in the summertime and warmer it is in the wintertime

Milwaukee, Wisconsin

5/5

First off the installation crew was great!  They worked very hard, took short breaks, and completed the job very efficiently. Greg Weber, our sales representative, told us an Interlock Roof was more energy efficient than asphalt, and one of the major things we noticed over the years is how much cooler our home office upstairs is in the summertime and warmer it is in the wintertime. It’s a dramatic difference from our old, asphalt roof.

We have had a few neighbors even question why we invested more in an Interlock roof than a typical asphalt roof, and we always smile and say, “Everybody complains about spending money. Do you want to complain about it once, or multiple times, and do you want to be all in to have the best, or not in, and hope for the best.”

Thank you Interlock!

Received a discount on our homeowner's insurance

Milwaukee, Wisconsin

Dear Interlock Lifetime Roofing Systems:

We purchased our Interlock Lifetime Roof in June of 2014. We are very happy with the look, durability of the material, and finish. 

After a snowfall, the heat of the sun will warm the roof and allow the snow to shed from the roof. We have a great sense of security knowing it can withstand higher winds than conventional asphalt. In fact, our neighbors lost many shingles in the last major wind storm and our Interlock roof proved to be the high wind resistance product it is with all shingles intact. We love the fact it’s more reliable and has peace-of-mind knowing it has lots of longevity and will look brand new not only now but down the road. We also received a discount on our homeowner’s insurance. 

Overall, we were very satisfied with our sales representative Greg Weber, the company, the service, and the product.

The roof is not any louder during several of the storms we have had already

Carol Stream, Illinois

5/5

Our new roof is beautiful! We have received so many compliments and inquiries since our Interlock roof was installed four weeks ago. John delivered on his promise with a quality product and set up the stage for what was to come, answering all our early questions and showing us the information we were looking for to make a confident decision.  He provided us installation pictures of previous jobs, the product specifications, color and type of samples, historical data on product performance and much more.  Dal from customer service responded quickly with dates when material was arriving and dates for the installation.  After some concerns about having to travel for work and being out of town, Al communicated well and they worked around my travel schedule and my family appreciated this greatly.

The roof is not any louder during several of the storms we have had already, than before. Despite a few outside temperatures reaching the 80s and sunny, the inside of the house has stayed cool without needing to turn on the AC or ceiling fans. It really is a new experience to walk into our second level rooms and not have it feel warmer than the lower level.

The installation crew did a great job. They told us everything they were doing and answered all of our questions. The fire department even stopped by during installation to ask what it was! The crew completed the job in 4 days, working over the weekend to finish before the next storm. They left the yard clean every night, and they cleared out the gutters from all of the debris.  After watching the team install the new roof safely, we have come to appreciate the craftsmanship that comes with installing this type of roof.  The crews are proud of the product and their care shows in the installation.  Putting on this new roof requires a lot of skill, a lot of hours, and experience that I think new owners won’t realize until observing them and going through it.  Minimal waste scraps, efficiently making thousands of measurements and metal shaping to perfectly fit all the corners and bends is a testament to the experience our crew lead by Jesse and Sal had.  

This Interlock company has been great and there have been so many people referenced here that have worked to provide us a great customer experience.  To the whole team, great job and thank you.  We look forward to the many years this roof will continuously perform as it was designed and the many more times we will appreciate the beauty of it.

Sincerely,

The advantages were so many and the expense over time was not much different from regular shingles

Milwaukee, Wisconsin

We visited the booth Interlock had at the Remodelling Show at State Fair Park. We got a lot of excellent information there and left our number for a call-back. We did receive the call back promptly and got an appointment right away. The estimator showed up on time and thoroughly explained the process, the product choices and the costs. We signed up for a new metal roof that evening because the advantages were so many and the expense over time was not much different from regular shingles. This metal roof will probably outlive us! The actual work didn’t start for about two months because the company is very busy, but removing the old layers of shingles was the first process. This was done in a day and the waterproofing membrane went on. The roofing materials were supposed to be delivered in a couple days, which unfortunately didn’t happen.

The actual work didn’t start for about two months because the company is very busy, but removing the old layers of shingles was the first process. This was done in a day and the waterproofing membrane went on. The roofing materials were supposed to be delivered in a couple days, which unfortunately didn’t happen. Instead, a heavy, rainy week intervened and we did get water in our kitchen. It took a while to get someone to call me back and that was frustrating because it damaged our kitchen ceiling. Ultimately, though, I did get a call and the work was expedited to the following day. The roofers did the entire install in one day and did a great job. The roof is beautiful and we have many people stopping and looking at the wonderful work and superior materials.

I know the company will honor their promise to pay for the damage to the kitchen. Once that is done, all is well. The experience wasn’t perfect, but it was as close as mother nature and shipping glitches allowed.

We are well pleased overall.

Seattle Homeowners Discover Year-Round Comfort With Interlock Metal Roofing: A Success Story

Seattle, Washington

Century-Old Seattle Home Gets Modern Roof Upgrade While Preserving Historic Charm

Gerald R. & Kathleen B. share their 5-star experience with Interlock Metal Roofing’ premium roofing solution.

When Gerald and Kathleen of Seattle, Washington, decided it was time to address the persistent leaks and overheating issues in their historic home, they turned to Interlock Metal Roofing for a solution. Their century-old residence—complete with original chimneys—presented unique challenges that previous roofing attempts had failed to solve.
Their complete 5-star Google review tells a compelling story about the transformation:

Let’s explore how Interlock Metal Roofing’ innovative metal roofing systems addressed Gerald and Kathleen’s specific concerns and why their experience resonates with Seattle homeowners and the Pacific Northwest.

Solving Complex Roofing Challenges in Historic Seattle Homes

One of the most remarkable aspects of Gerald and Kathleen’s review is the mention of their 100-year-old chimneys. These chimneys, being a century old, were not only a part of the home’s history but also a unique architectural feature that posed a challenge for standard roofing solutions. The skilled Interlock installation team demonstrated their expertise by successfully adapting the metal roofing system around these chimneys, preserving their historic charm while providing modern protection.

“During installation, your crew was able to adapt the project around our 100-year-old chimneys and finally completely seal us against leaks,” the homeowners noted. This highlights a crucial advantage of choosing Interlock Industries: combining premium materials with expert installation techniques designed to handle complex architectural elements.
For Seattle homeowners with historic properties, this attention to detail makes all the difference between a temporary fix and a permanent solution that preserves the home’s character while providing modern protection.

Energy Efficiency: The Unexpected Benefit That "Exceeded Expectations"

Perhaps the most compelling part of Gerald and Kathleen’s testimonial relates to the dramatic improvement in their home’s comfort level: “The first summer of the new roof was worth the project’s price and exceeded our expectations for performance. We did not have the old problems of the attic area overheating. The attic fan barely comes on unless it is a hot day.

This experience perfectly illustrates why Interlock Metal Roofing has earned its reputation as “Seattle’s Best Roof” and why the same benefits apply to homes in the Pacific Northwest. The reflective properties of Interlock’s aluminum roofing systems significantly reduce heat absorption, creating more comfortable living environments and reducing cooling costs.

This meant a dramatic improvement in Gerald and Kathleen’s third-floor bedrooms: “But we no longer feel the heat on the third floor, where all the bedrooms are. Less heat means more comfortable nights and sleep.”
This energy efficiency benefit is especially valuable in Seattle homes, where summers have grown increasingly warm in recent years. Homeowners who choose Interlock Metal Roofing systems typically experience:

  • Reduced attic temperatures by up to 25°F
  • Lower cooling costs during summer months
  • More consistent indoor temperatures
  • Improved sleeping conditions in upstairs bedrooms
  • Reduced wear on cooling equipment

Aesthetics That Complement Seattle's Architectural Diversity

A common concern among Seattle homeowners considering metal roofing is how it will look on their homes. Gerald and Kathleen directly addressed this in their review:

“Even the house’s exterior looks better, but surprisingly, the roof does not look like it was covered with metal. The selected pattern fits the house’s look and looks compatible with our neighborhood houses.”

This observation highlights another key advantage of Interlock Metal Roofing systems. Available in various profiles that complement diverse architectural styles—from Queen Anne Victorians to Craftsman bungalows to mid-century modern homes—these roofing systems enhance curb appeal while providing superior protection.

Gerald and Kathleen’s roof seamlessly blends with their neighborhood aesthetic, demonstrating how far metal roofing technology has advanced. Modern Interlock systems bear little resemblance to the utilitarian metal roofs of the past but instead offer sophisticated profiles that complement Seattle’s historic and contemporary homes.

The Long-Term Value of Quality and Guarantees for Seattle Homeowners

When Gerald and Kathleen conclude their review by mentioning, “We are very pleased with the roof and the guarantee that accompanies the roof,” they touch on something many Seattle homeowners value: long-term protection. This guarantee provides exceptional peace of mind in Seattle’s challenging climate.

Interlock’s premium metal roofing systems are backed by a comprehensive lifetime limited warranty. This warranty, which supports the company’s promise to help homeowners’ Never Re-Roof Again, is a testament to the quality and durability of Interlock’s products. In Seattle’s challenging climate, where abundant rainfall, occasional windstorms, and seasonal temperature fluctuations can quickly deteriorate traditional roofing materials, this guarantee provides exceptional peace of mind and underscores the long-term value of choosing Interlock.

This long-term value proposition is particularly compelling for owners of historic Seattle homes like Gerald and Kathleen. Their investment protects their century-old residence from water damage, enhancing comfort and energy efficiency for decades.

Why Seattle Homeowners Are Making the Switch to Metal Roofing

Gerald and Kathleen’s story reflects a growing trend among Seattle homeowners choosing metal roofing systems over traditional materials. The reasons behind this shift include:

  1. Superior durability in Seattle’s wet climate: Interlock’s heavy gauge aluminum won’t deteriorate with constant exposure to moisture.
  2. Wind resistance: The 4-way interlocking design provides exceptional protection during Pacific Northwest windstorms.
  3. Energy efficiency: Reflective properties reduce cooling costs during increasingly warm Seattle summers.
  4. Environmental benefits: Metal roofing is 100% recyclable and can be installed over existing roofs, reducing landfill waste.
  5. Long-term value: The lifetime limited warranty eliminates the expense and hassle of periodic roof replacements.
  6. Aesthetic versatility: Modern profiles complement Seattle’s diverse architectural styles while maintaining neighborhood character.
  7. Property value enhancement: Like Gerald and Kathleen discovered, premium metal roofing can improve a home’s appearance and market value.

Experience the Interlock Difference for Your Seattle Home

Gerald and Kathleen’s willingness to “show the roof to people interested in the Interlock Industries product” speaks volumes about their satisfaction. This kind of enthusiasm comes from experiencing transformative results that address real problems—in their case, eliminating leaks around century-old chimneys and creating more comfortable living spaces throughout their home.

Interlock Metal Roofing offers a proven solution for Seattle homeowners facing similar challenges with aging roofs, increasing energy costs, or persistent leaks. The company’s combination of premium materials, expert installation, and comprehensive warranty protection provides exceptional value for historic and contemporary homes throughout the Pacific Northwest.

Like Gerald and Kathleen discovered, the benefits extend beyond basic weather protection, including improved comfort, enhanced aesthetics, and the peace of mind that comes with knowing you’ll “Never Re-Roof Again.”

Interlock Metal Roofing provides premium metal roofing solutions for homeowners throughout Seattle and the Pacific Northwest. It has specialized experience addressing the unique challenges of historic homes and diverse architectural styles.

Top 10 FAQS for Seattle Homeowners Considering a New Roof

How long will traditional roofing materials last in Seattle's wet climate?

Standard asphalt shingles typically last only 15-20 years in Seattle’s rainy conditions, with premature deterioration common due to our persistent moisture and occasional algae growth. Once popular in our region, Cedar shakes often require significant maintenance and typically last 20-25 years before needing replacement. In contrast, Interlock Metal Roofing’s heavy-gauge aluminum systems are designed for Seattle’s challenging climate. They are backed by a lifetime limited warranty, allowing you to “Never Re-Roof Again.”

Interlock Metal Roofing systems excel in Seattle’s notoriously wet conditions. The 4-way interlocking design creates a virtually impenetrable barrier against our heaviest downpours. Unlike traditional roofing, which can develop leaks as materials deteriorate from constant moisture exposure, our aluminum roofing maintains its integrity decade after decade. The system also features advanced water channelling that efficiently directs rainfall away from your home, providing superior protection against Seattle’s 150+ rainy days per year.
This is our region’s most common misconception about metal roofing. Interlock Metal Roofing systems are installed with solid sheathing and proper insulation, which makes them no louder than traditional roofing during rainfall. Many Seattle homeowners, like Gerald and Kathleen, who recently shared their 5-star experience, report that their Interlock roof is quieter than their previous roof. The solid substrate beneath our roofing systems effectively dampens sound, allowing you to enjoy the peaceful patter of Seattle rain without disruptive noise. Another homeowner, Sarah, was initially concerned about the noise but was pleasantly surprised by the quietness of her Interlock roof during a heavy downpour.
Seattle experiences several windstorms annually, particularly during fall and winter. Interlock’s 4-way interlocking design is specifically engineered to withstand high winds that can damage or dislodge traditional roofing materials. The interconnected panels create a unified surface that resists wind uplift, preventing damage commonly seen with asphalt shingles or cedar shakes during our stronger Pacific storms. This superior wind resistance provides invaluable peace of mind during Seattle’s storm season.
Absolutely! Interlock Metal Roofing systems provide remarkable energy efficiency benefits in our unique climate. During Seattle’s increasingly warm summers, the reflective properties of our aluminum roofing significantly reduce heat absorption, keeping attics cooler and reducing cooling costs. Seattle homeowners like Gerald and Kathleen have reported that after installation, “the attic fan barely comes on unless it is a very hot day,” and they’re “no longer feeling the heat on the third floor.” This energy efficiency not only saves on utility bills but also reduces your home’s carbon footprint, making it an environmentally conscious choice for Seattle homeowners.
Interlock Metal Roofing systems are designed to enhance your Seattle home’s aesthetic appeal while significantly increasing its value. Available in multiple profiles that complement our region’s diverse architectural styles—from Craftsman and Tudor to modern Northwest Contemporary—our roofing systems can be customized to suit your home perfectly. As Seattle homeowners Gerald and Kathleen noted in their review, “Even the house’s exterior looks better, but surprisingly the roof does not look like it was covered with a metal material. The selected pattern fits the house’s look and looks compatible with our neighborhood houses.” This enhanced curb appeal and the transferable lifetime limited warranty make your home more attractive to future buyers in Seattle’s competitive real estate market.
Interlock Metal Roofing systems are exceptionally well-suited for Seattle’s abundant historic homes. Our installation teams have extensive experience adapting our premium roofing systems to the unique architectural features standard in older Seattle residences. As Seattle homeowners Gerald and Kathleen shared about their century-old home, “During installation, your crew was able to adapt the project around our 100-year-old chimneys and finally completely seal us against leaks.” Our roofing profiles can maintain the authentic character of your historic Seattle home while providing modern protection and energy efficiency benefits that weren’t available when these cherished homes were built. Our team works closely with homeowners to ensure that the installation process respects the historical integrity of the home while providing the benefits of a modern roofing system.
One of the most significant benefits of choosing Interlock Metal Roofing in Seattle is the minimal maintenance required. Unlike traditional roofing materials that can develop moss, algae, and fungal growth in our humid environment, our aluminum roofing systems remain virtually maintenance-free. Occasional rinsing with a garden hose to remove pine needles, leaves, or debris is typically all that’s needed. You won’t need to clean moss, replace damaged shingles after windstorms, or worry about deterioration from constant moisture exposure—common maintenance issues with traditional Seattle roofs. This minimal maintenance requirement is particularly valuable given many Seattle homes’ standard height and steep pitches, providing you with peace of mind and more time to enjoy your home.
Seattle’s proximity to Puget Sound means many homes experience salt-laden air, which can accelerate the deterioration of many building materials. Interlock’s heavy gauge aluminum roofing systems will not rust or corrode even with continuous exposure to marine air. This makes them ideal for waterfront properties and homes in Seattle that experience salt spray during storms. The non-corrosive nature of our aluminum roofing ensures decades of protection without the degradation commonly seen with other materials in our unique coastal environment.

Interlock Metal Roofing systems are protected by a comprehensive lifetime limited warranty that supports our promise that Seattle homeowners will “Never Re-Roof Again.” This warranty covers manufacturing defects, material failure, and specific weather-related damages—far more extensive than the limited coverage offered with traditional roofing materials. The warranty is transferable to new owners if you sell your Seattle home, adding significant value to your property. As Seattle residents Gerald and Kathleen mentioned in their review, they were “very pleased with the roof and the guarantee that accompanies the roof,” highlighting the peace of mind that comes with knowing your home is protected for life with Seattle’s Best Roof.

The interconnected panels create a unified surface that resists wind uplift, preventing damage commonly seen with asphalt shingles or cedar shakes during our stronger Pacific storms. This superior wind resistance provides invaluable peace of mind during Seattle’s storm season.
Absolutely! Interlock Metal Roofing systems provide remarkable energy efficiency benefits in our unique climate. During Seattle’s increasingly warm summers, the reflective properties of our aluminum roofing significantly reduce heat absorption, keeping attics cooler and reducing cooling costs. Seattle homeowners like Gerald and Kathleen have reported that after installation, “the attic fan barely comes on unless it is a very hot day,” and they’re “no longer feeling the heat on the third floor.” This energy efficiency not only saves on utility bills but also reduces your home’s carbon footprint, making it an environmentally conscious choice for Seattle homeowners.
Interlock Metal Roofing systems are designed to enhance your Seattle home’s aesthetic appeal while significantly increasing its value. Available in multiple profiles that complement our region’s diverse architectural styles—from Craftsman and Tudor to modern Northwest Contemporary—our roofing systems can be customized to suit your home perfectly. As Seattle homeowners Gerald and Kathleen noted in their review, “Even the house’s exterior looks better, but surprisingly the roof does not look like it was covered with a metal material. The selected pattern fits the house’s look and looks compatible with our neighborhood houses.” This enhanced curb appeal and the transferable lifetime limited warranty make your home more attractive to future buyers in Seattle’s competitive real estate market.
Interlock Metal Roofing systems are exceptionally well-suited for Seattle’s abundant historic homes. Our installation teams have extensive experience adapting our premium roofing systems to the unique architectural features standard in older Seattle residences. As Seattle homeowners Gerald and Kathleen shared about their century-old home, “During installation, your crew was able to adapt the project around our 100-year-old chimneys and finally completely seal us against leaks.” Our roofing profiles can maintain the authentic character of your historic Seattle home while providing modern protection and energy efficiency benefits that weren’t available when these cherished homes were built. Our team works closely with homeowners to ensure that the installation process respects the historical integrity of the home while providing the benefits of a modern roofing system.
One of the most significant benefits of choosing Interlock Metal Roofing in Seattle is the minimal maintenance required. Unlike traditional roofing materials that can develop moss, algae, and fungal growth in our humid environment, our aluminum roofing systems remain virtually maintenance-free. Occasional rinsing with a garden hose to remove pine needles, leaves, or debris is typically all that’s needed. You won’t need to clean moss, replace damaged shingles after windstorms, or worry about deterioration from constant moisture exposure—common maintenance issues with traditional Seattle roofs. This minimal maintenance requirement is particularly valuable given many Seattle homes’ standard height and steep pitches, providing you with peace of mind and more time to enjoy your home.
Seattle’s proximity to Puget Sound means many homes experience salt-laden air, which can accelerate the deterioration of many building materials. Interlock’s heavy gauge aluminum roofing systems will not rust or corrode even with continuous exposure to marine air. This makes them ideal for waterfront properties and homes in Seattle that experience salt spray during storms. The non-corrosive nature of our aluminum roofing ensures decades of protection without the degradation commonly seen with other materials in our unique coastal environment.

Interlock Metal Roofing systems are protected by a comprehensive lifetime limited warranty that supports our promise that Seattle homeowners will “Never Re-Roof Again.” This warranty covers manufacturing defects, material failure, and specific weather-related damages—far more extensive than the limited coverage offered with traditional roofing materials. The warranty is transferable to new owners if you sell your Seattle home, adding significant value to your property. As Seattle residents Gerald and Kathleen mentioned in their review, they were “very pleased with the roof and the guarantee that accompanies the roof,” highlighting the peace of mind that comes with knowing your home is protected for life with Seattle’s Best Roof.

It may be more money than your asphalt shingles, but it is well worth every penny

I love the roof! It looks great and the squirrels that we’re crawling all over my old asphalt roof slide right off it. The snow slides off, too.

I hope to get some $500 referrals. The crew was terrific, hardworking, courtesy, polite, and clean.

The Interlock crew was able to take some extra time to coordinate with another contractor for solar installation.

As a result the final the result looks great and very functional. The materials used are very high quality and they worked efficiently and cleaned up when finished.
