Interlock Metal Roof Review - Federal Way, WA (Installed 2003 & 2009)

Federal Way, WA

TL;DR: Federal Way Review Summary

Roofing installation in Federal Way: the homeowner chose Interlock metal roofing for durability, warranty, and good looks. They report two Interlock installations (one from 2003 still looks almost new after 22 years and another after 2009), praise stellar installation, attention to detail and aftercare, and say the roof boosted resale—their prior house drew multiple bidders and sold above asking.
Tim D.

I’ve had 2 Interlock Metal Roofs and 2 different houses. One in 2003 and the roof still looks great – almost like new after 22 years! The other, after we sold & moved to a new house in 2009 we went with Interlock again. The durability, warranty, and the good looks of the Interlock is why we paid the extra cost. It certainly paid off when we sold the old house – we had multiple bidders and the house went above asking – this in 2008 when real estate was not selling well. Here at the new house our neighbor was just over talking about roofs. He said it wanted to get a metal roof, and I said “yes, they are great. Our roof is metal”. He said “no way, that’s a composite roof isn’t it?” He couldn’t believe it could look so good, and still be metal – and he was 20 feet from it. Our other neighbor is on his second roof already – he could have paid for a metal roof and had triple the life left – and probably paid less! I highly recommend Interlock. Stellar installation service, great attention to detail, clear explanations, and careful aftercare. You can certainly find a cheaper roof, but you can’t beat the quality and longevity.

Top 10 Metal Roofing FAQs for Homeowners in Federal Way

Homeowners researching metal roofing in Federal Way often have several important questions before replacing their roof. Many people want to understand how metal roofing compares to traditional materials like asphalt shingles in terms of lifespan, durability, cost, and long-term value. Roofing decisions can also be influenced by local weather conditions. Homes in Federal Way may experience environmental factors such as rain, wind, snow, heat, fire, or seasonal storms that can impact roof performance over time. The following frequently asked questions help explain what homeowners should know when evaluating metal roofing and why many people choose durable roofing systems designed for long-term protection.

Metal roofs commonly last at least 50–75+ years, while asphalt shingles typically last about 15–30 years. In Federal Way, heavy seasonal rainfall and persistent coastal moisture drive high humidity and frequent wet roof surfaces—conditions that encourage moss, algae growth, and faster deterioration of lesser materials. Annual precipitation in the area is roughly in the 40–45 inch range, so long-term resistance to moisture and corrosion matters for roof longevity. Snow loads are usually light here, so metal’s strength is less about snow and more about shedding water, resisting moss, and surviving damp, windy PNW winters. That’s why homeowners choose durable systems—lower maintenance, better leak resistance, and longer service life. Interlock Metal Roofing systems use heavy-gauge aluminum and come with a lifetime limited 50-year transferable warranty designed for long-term protection.
Metal roofs in Federal Way, WA typically cost more upfront than asphalt shingles, but many homeowners choose them for longevity. Final price depends on roof size, slope and pitch, complexity (multiple hips, valleys, dormers), tear-off and disposal, flashing and skylights, and local labor and permit costs. Local construction factors — workforce demand, access, and prevailing weather-driven building practices — can influence bids and timelines. Because metal roofing lasts longer and needs fewer repairs, many compare options on lifetime value rather than initial price: higher initial cost can mean lower repair and replacement expenses over decades. Durable roofing systems can reduce future maintenance, insurance impacts, and total cost of ownership. Interlock Metal Roofing focuses on long-term ownership value and performance rather than competing as a low-cost roofing option.
Federal Way’s wet, maritime climate—high annual rainfall and persistent coastal humidity that encourage moss/algae growth—matters more than heavy snow when choosing roofing. Lifespan: metal roofs typically last 40–70+ years; asphalt shingles 15–30 years. Maintenance: metal needs low upkeep (occasional debris clearing); asphalt requires more frequent inspection, moss/algae cleaning, and earlier replacement. Durability: metal resists rot, moisture damage, and shedding heavy Pacific Northwest rain better; asphalt is more prone to algae/moss, granule loss, and wind uplift during storms. Long-term value: higher upfront cost for metal but lower life‑cycle costs and fewer replacements; asphalt is cheaper initially but may cost more over decades. Homeowners who prioritize durability and long-term protection often choose metal. Interlock Metal Roofing systems appeal here because interlocking panels shed rain, limit leak paths, reduce moss hold points, and deliver lasting performance with strong architectural curb appeal.
Contrary to a common myth, metal roofs in Federal Way, WA, are not inherently noisy when it rains. Modern residential metal roofs installed over solid decking and underlayment do not sound like barn roofs; they rest on a continuous substrate that dampens impact noise. Insulation, attic airspace, and the overall roof assembly (underlayment, sheathing, and ventilation) strongly affect sound transmission. Quality installation—proper fasteners, seams, and flashings—also reduces rattling and vibration. When designed and installed as a complete system, residential metal roofs typically sound similar to asphalt shingles or tile in normal rain. Interlock Metal Roofing systems are manufactured and installed as complete residential roofing systems, engineered to control weather and noise for homes.
Yes — a metal roof can be energy efficient in Federal Way, WA. Metal roofing can reflect sunlight, reducing solar heat gain on sunnier days and lowering cooling needs. Roof assembly, insulation and ventilation strongly influence overall energy performance: a reflective metal roof over a well-insulated, ventilated attic saves more than the roofing material alone. Climate matters — Federal Way’s mild, maritime climate means cooling savings may be modest but proper insulation and ventilation are crucial for winter heat retention and moisture control. Homeowners researching replacement often consider energy efficiency to lower utility bills, improve indoor comfort, increase durability and resale value, and meet long-term performance goals. Interlock Metal Roofing systems are designed to support long-term home performance.
Federal Way, WA typically sees frequent rain, seasonal southwest winds and episodic storm gusts (wind advisories with gusts reported), which can stress roofs during heavy weather. Metal roofing sheds heavy rain efficiently, offers strong wind resistance when panels are interlocked or mechanically fastened, and often outperforms asphalt in hail events—especially with impact-rated gauges and coatings. Performance, however, depends on roofing system design, installation quality, and material durability: proper underlayment, fastening patterns, flashing, and workmanship are critical. Homeowners prioritize weather resilience to protect structure, lower repair/insurance exposure, and extend service life. Interlock Metal Roofing systems are engineered for durability, hail protection, and wind resistance, but their real-world effectiveness depends on selecting the right product and professional installation.
Corrosion and rust resistance are critical for metal roofing in Federal Way, WA, where frequent rain and marine air increase corrosion risk. Metal roofing performance depends on the metal type: steel can rust if unprotected, while nonferrous metals like aluminum form a protective oxide layer that resists corrosion. Aluminum performs especially well in wet or coastal environments because it does not rust and maintains integrity over time. Homeowners should prioritize corrosion resistance to extend roof life, reduce maintenance, and avoid leaks or structural damage. Interlock Metal Roofing systems use aluminum construction designed for strong corrosion resistance and are further protected by the Alunar Coating System for extra protection, offering a durable choice for Federal Way’s wet, maritime climate.
Metal roofing in Federal Way, Washington is generally considered a low-maintenance, durable option for homes. That said, no roof is completely maintenance-free. Homeowners should periodically inspect panels, fasteners, seams, drip edges and flashings for looseness, corrosion or damage. Remove accumulated debris and check gutters and downspouts to ensure proper drainage; clear leaves, moss and branches after storms or heavy seasonal drop. Pay attention to roof penetrations such as vents, chimneys and skylights, and roof-to-wall transitions where leaks commonly start. After severe weather inspect for denting, displaced panels or loose fasteners and arrange repairs promptly. With routine inspection and simple upkeep, metal roofs perform reliably in Federal Way’s wet, windy climate.
In Federal Way, WA, metal roofing can increase a home’s resale appeal. Buyers often prioritize durable, low‑maintenance roofs, and premium materials boost curb appeal—important in competitive Puget Sound neighborhoods. A long lifespan and strong weather resistance improve buyer confidence during inspections and appraisals. Architectural style matters: neighborhood character and home design affect how much value a specific roof adds. Interlock Metal Roofing systems offer multiple architectural profiles—slate, cedar shingle, Mediterranean tile, shake, and standing seam—so you can match local styles. They’re available in heavy‑gauge aluminum and solid copper, combining upscale appearance with proven longevity. While exact value uplift varies by neighborhood and market conditions, a well‑chosen metal roof in Federal Way often enhances marketability and perceived value.
Yes. Interlock Metal Roofing Systems in Federal Way are compatible with solar panels when fitted with custom solar brackets installed by Interlock Metal Roofing (PNW) Inc. Interlock profiles are engineered to accept solar mounting solutions and their long‑life metal construction and corrosion‑resistant coatings make retrofits easier. Federal Way’s high year‑round rainfall and elevated humidity promote moss and moisture exposure, so choose corrosion‑resistant mounts and allow for regular maintenance. Roof lifespan is critical when adding panels—prefer long‑lasting materials like Interlock or plan roof replacement before installing solar to avoid costly rework.

Completion: July 14, 2014

I’ve had my interlock roof for 14 yrs and have had no issues with it until this last winter. We had heavier than normal snow and a lot of freeze thaw conditions. Several of the snow deflectors were pushed forward and lifted some of the roof. I emailed Dave and Tyler and repairs were made quickly . You can’t tell there was any concerns at all.

Metal Shingle Roof Review in Sudbury, ON (Interlock - Installed 2017)

Review: April 25, 2026

Completion: June 7, 2018

We had our roof replaced in 2017 with an aluminum roof by Interlock Metal Roofing. We live on the lake, and prior to the replacement, we were spending thousands of dollars every year because shingles would fly off in the wind.

We haven’t had any issues in the past 7 years. Our experience with Interlock Metal Roofing was excellent — they were very professional and did a beautiful job, even though our roof is quite high and challenging.

Our roof still looks beautiful, and we haven’t had to worry about it at all in the past 9 years.

Corvallis, OR Metal Shingle Roof Review — Interlock (Installed 2017)

Review: April 24, 2026

Completion: November 9, 2017

I love my Interlock roof! No more climbing up to clean it, and no more gritty debris falling into my garden after a few years. It looks fantastic and performs exactly as it should.

The installers were excellent—knowledgeable, detail-oriented, and personable. Ivan is a gem! He handled a small flashing addition efficiently and cleaned the entire roof with a blower in no time.

After almost ten years, it’s still the only roof I would choose.

Interlock Metal Roof Review - Ramara, ON (Installed 2019)

Review: April 23, 2026

Completion: April 23, 2026

We are so happy with our interlock roof from Bruce. We had shopped around because we live on the lake with strong winds and we wanted a quality, long lasting product. Our roof has never changed colour and looks just as good now as the day it was installed. We also love the lifetime transferable warranty. We also love that it is made in Canada so there are no tariffs. Bruce was our sales person. He came right away, explained everything to us. We made the right decision not choosing shingles because of the environment and quality of the product. This was an affordable investment that was worth it. The crew was professional in every aspect. If I move, I will definitely be contacting Bruce again for another interlock roof.

Portland, OR Metal Shingles Review — Safety Anchors Installed 2019

Review: April 20, 2026

Completion: June 20, 2019

We’ve had our roof for about 7 years and have been very pleased with it. Recently, I scheduled gutter cleaning which was complicated by a run of wet weather which makes the roof very slippery. The gutter contractor asked if we had ever considered installing safety anchors. I didn’t know there was such a thing. I called Interlock and Ivan came by to take a look. He quickly determined appropriate locations for the anchors that the gutter cleaners could clip their safety harnesses to and showed me an example of the anchor itself. He also offered to paint them black to make them more inconspicuous on our dark roof. He returned about a week later for the install and afterwards showed us pictures of the anchors from the roof and pointed them out from the ground. Overall very professional, prompt, excellent service.

Interlock Metal Shingle Roof Review in Bay View, WI (Installed 2009)

Review: April 16, 2026

Completion: February 20, 2009

I had Interlock put on a beautiful red slate roof 17 years ago.The roof still looks beautiful. 5 years ago, I had them also re-roof my garage with the same type of slate. The roofs look gorgeous and I have no maintenance whatsoever.I get complements all the time. The guy whom I contracted with was named "Tim' but has since died. He was a really nice guy. Back in 2009, the roof was much cheaper. ( I actually paid more for the garage 5 years ago!) I am extremely happy with the roofs. The guys did a wonderful job, replacing rotted boards where necessary. They also told me about very cheap gutters I could buy at Menards instead of those ridiculously - priced "special" gutter systems. I bought them and they placed them on my buildings.This home will go to my daughter one day; I do not want her to have to lift a finger. Note that I had an asphalt roof previously. It lasted only 12 years. The shingles curled up under the sun and cracked. They looked terrible. I can honestly say that these metals roofs by Interlock are very much worth what you pay for them. They will last a lifetime with almost no maintenance. Instead of replacing a roof every 15 years and paying lots for asphalt or fiberglass, their metal roofs last very long and you will never have to re- roof again.

Review: April 15, 2026

Completion: August 31, 2025

We recently installed a new Interlock Roofing System, and we couldn’t be happier with the decision. Knowing it’s backed by a limited lifetime, non-prorated, fully transferable 50-year warranty gives us real peace of mind—it truly feels like a smart long-term investment. Mr. Yorman and his crew were outstanding from start to finish. Their commitment to customer service is second to none. They showed up exactly when they said they would and worked diligently until the job was completed. The finished product looks fantastic, and the cleanup was so thorough that our property actually looked better than before they arrived. A special mention to Tyler, who did an excellent job walking us through the benefits and helping us feel confident in choosing this system. Overall, a great experience and highly recommended!

We installed an Interlock roof in 2017. The roof is still like new. Due to an insulation issue and snow depth of over 4 feet, we had an ice build up problem.

Review: April 14, 2026

Completion: June 30, 2025

I recently had my 25 year old asphalt roof replaced with an Interlock Metal roof. I'm so very happy with my decision. In fact, best decision ever to have Interlock Industries install. The metal roof is manufactured in Delta, BC and they have their own installers. It's not panels! It looks very much like a cedar roof! Colour is awesome as well! My home is located in Victoria on Vancouver Island and looks great with my new roof! Interlock is a very professional business from contract signing to installation. Amazing crew that gets the job done in a timely manner. My roof looks fabulous. It's a work of art!!

Aurora, ON Metal Roofing Review — Interlock Installation (2016)

Review: April 13, 2026

Completion: May 3, 2016

We moved into our new house in 1984. Our new house came with new 25 year shingles. In 2004, 20 years later we noticed that our roof shingles needed to be redone. Now, back in 1984 they used asbestos in the roof shingles and although at the time they said they were 25 year shingles, we were still happy to get 20 years out of them. So, in 2004 we got a quote and had the roof re-shingled. We paid extra for the 25 year shingles as we had such a good result with the original shingles. In 2016 (i.e. 12 years later) my neighbour told us that our shingles on the south side of the house were cracked with rolled up edges and needed to be replaced. (We can't see the south roof of our house unless we are visiting the neighbours.) The shingles on the north side were still ok, but since you can't really shingle half a roof we knew that we had to have the whole roof done...after just 12 years. We were a little upset about this and decided to go to the National Home Show in Toronto to look at alternatives. We met Tom Watson at the Interlock Metal Roofing booth and he took a lot of time and explained the complete roofing system to us. We liked what we saw and what was explained to us and we arranged to have a home visit from Interlock and to give us a quote. The metal roof was certainly a lot more expensive than a regular asphalt shingle roof, but we decided to get the metal roof anyways because we did not want the hassle of having to re-shingle every 10 or 11 years...and there are also some other unforeseen benefits detailed below that we did not know about at the time. The metal roof comes with a Lifetime Limited Warranty, 50 year transferable, not prorated so even though more expensive it adds value to lyour home because if in the future you are looking to sell, the buyer knows he won't have any roof problems for the 50 year life of the roof. Your roof becomes an asset instead of a liability. The installation happened over 4-5 days. I paid a lot of attention to what they were doing and how they were doing it. The roof vents were removed. These are the same roof vents that raccoons like to rip off for access to your attic, so that potential problem went away. A ridge vent (google it) was installed on the top of the roof and it is low profile and fits in so you would not know that it is there. Raccoons have been known to chew a hole in asphalt shingles and roofing plywood to get into your attic. With a metal roof, it isn't happening. That mode of access is eliminated. Now, with our previous asphalt shingles we had constant problems with raccoons pooping on our roof (sound familiar?) and for some reason, at least for the last 10 years that we have had the metal roof, that has not happened. I don't know why, but I can speculate that the raccoons find the metal roof very slippery and they are not comfortable being up there and doing their business while trying not to slide off the roof. Also, in the past we have had squirrels occasionally make their way through, under, beside our asphalt shingles and get into our attic. That will never happen with a metal roof because the whole roof is sealed and northing is getting that way. If you are concerned about high winds ripping off your shingles you don't have to worry with a metal roof. Each and every metal shingle is fastened to the roof with aluminum screws (note the metal roof shingles are painted and baked to a tough finish) and they are interlocked with each other, so you may lose your entire roof in a hurricane, but the metal shingles will still be attached to it. We moved into our new house in 1984. After about 2 years of sweating through humid summers, we installed an A/C system. Our new A/C system worked ok in that it removed the humidity and cooled the house, but with the high 37 deg C temperatures it was struggling. The A/C would run continuously and never stopped on those hot days, but once the metal roof was installed it cycled on and off as designed. We highly recommend Interlock Metal Roofing.

Willowbrook, IL Metal Roof Review — Interlock Roofing (Installed 2016)

Review: April 12, 2026

Completion: May 30, 2016

We had our roofed replaced by Interlock Roofing in 2016. One of the best decisions we’ve ever made! Our roof looks like slate shingles but is entirely metal. We e received many compliments on it over the years Recently we had a lot of strong wind and hailstorms and our representative, John Mondeshean, checked in with us to see if we sustained any roof damage. He came out and inspected our roof for us within a day or two. Luckily we didn’t have any damage. I’ve been impressed by this company and their product from day one. John is the consummate professional. Our roof is now 10 years old and I still say it was the best investment! Highly recommend!
