Seattle, WA Metal Roofing Review — Craftsman Steep Roof Install (2025)

Seattle, WA

TL;DR: Seattle Review Summary

Roofing installation in Seattle, Washington on a 1911 Craftsman with steep roofs, multiple bump-outs, and tight access between neighboring houses. Patrick, Tony, and the installation crew tore off old composite shingles, installed new underlayment the same day, replaced a few water-damaged boards, and finished within a week; it rained hard the next day and prior leaks stayed dry, leaving the homeowner pleased and neighbors complimentary.

It’s such a relief to have a beautiful, reliable roof over our house now. Patrick, Tony, and the installation crew had their work cut out for them with our 1911 Craftsman’s steep roofs, several bump-outs, and other added details. We’re also nestled pretty tightly in between three other houses, so access points were somewhat limited. But they rose to the challenge admirably. Tearing off the old composite shingle took the better part of one day, but they managed to get new underlayment installed everywhere by the end of it. Unsurprisingly, they found some water damage along the way as well, so they had to replace a few boards, which set them back a little. But all in all, they finished within the week and we’re so pleased with the result. It rained hard the day after and all the old leaks we had stayed nice and dry. Our neighbors complimented us on the new roof as well.

Top 10 Metal Roofing FAQs for Homeowners in Seattle

Homeowners researching metal roofing in Seattle 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 Seattle 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; asphalt shingles typically last 15–30 years. Seattle averages roughly 37–39 inches of rain and about 150 precipitation days a year, with a cool, maritime climate and high humidity that encourages moss and algae growth on shaded asphalt roofs. Those local factors—persistent rainfall, coastal moisture and humidity—tend to shorten asphalt lifespan by promoting rot, moss and granular loss, while Seattle’s generally low snow loads reduce freeze–thaw stress. Metal roofing sheds water, resists moss and, when anodized or aluminum, withstands coastal corrosion better than painted steel. That durability and reduced maintenance is why many Seattle homeowners choose long‑life metal systems. Interlock Metal Roofing systems use heavy‑gauge aluminum and include a lifetime limited 50‑year transferable warranty designed for long‑term protection.
Metal roofs in Seattle typically cost more upfront than asphalt shingles, but many homeowners choose them for longevity and performance. Final price depends on roof size, slope/pitch, complexity (hips, valleys), tear-off and disposal, flashing and penetration work (chimneys, skylights), and labor. Local construction factors—Seattle permit costs, contractor availability, prevailing labor rates, and exposure to heavy rain or coastal air—can also affect bids. Rather than comparing only initial price, many homeowners evaluate lifetime value: energy savings, lower maintenance, and longer service life can reduce total cost over decades. Durable metal roofing systems often lower future repair and replacement expenses compared with lower-cost alternatives. Interlock Metal Roofing focuses on long-term ownership value and performance rather than competing as a low-cost roofing option.
Is metal roofing worth it compared to asphalt shingles in Seattle? Seattle’s wet, mild climate—about 37 inches of annual precipitation—plus persistent humidity and shaded roofs encourages moss and algae that accelerate shingle wear. Lifespan: metal often lasts multiple decades (commonly 40+ years) versus roughly 15–30 years for asphalt. Maintenance: metal needs less frequent cleaning and resists moss/algae; asphalt requires regular moss removal, cleaning and occasional patching. Durability: metal better withstands prolonged moisture, rot and wind; asphalt is more prone to moisture-related deterioration in Seattle’s damp conditions. Long-term value: higher upfront cost for metal can pay off through fewer replacements and lower maintenance for homeowners prioritizing durability and long-term protection. Interlock Metal Roofing systems appeal because interlocking panels improve watertightness and longevity while providing strong architectural curb appeal.
This is a common myth: metal roofs are noisy in rain. Modern residential metal roofs installed over solid decking with proper underlayment and insulation do not sound like barn roofs. Sound depends on the roof assembly: insulation, attic space, underlayment, and fasteners all dampen impact noise. Quality installation, solid decking, and ventilation reduce flanking noise; poor installation or exposed purlins can increase it. Properly installed residential metal roofs are typically similar in sound to asphalt shingles or tile during rain. Interlock Metal Roofing systems are manufactured and installed as complete roofing systems designed for residential homes, incorporating decking, underlayment, and fastening details to minimize noise.
Metal roofing can be energy efficient in Seattle because many metal products reflect sunlight, reducing solar heat gain during the sunnier days. However, overall performance depends on the entire roof assembly — insulation levels, air sealing and attic ventilation have as much or more impact on heating and cooling loads than the roof material alone. Seattle’s mild, maritime climate with cloudy winters and occasional summer sun means reflective finishes yield modest summer cooling benefits but less heating penalty than in colder, snowy climates. Homeowners researching roof replacement often consider energy efficiency to lower utility bills, improve year‑round comfort, qualify for rebates or code upgrades, and increase resale value. Interlock Metal Roofing systems are designed to support long‑term home performance and work with proper insulation and ventilation strategies.
In Seattle, WA, roofs face heavy seasonal rain, frequent windy periods (southwest gales), and episodic convective storms that can bring hail and damaging gusts. Metal roofing sheds water well, resists corrosion, and—when properly specified—offers strong wind-uplift resistance; it also generally withstands hail better than asphalt shingles, though very large hail can dent panels. Performance depends on roofing-system design (profile, fasteners, underlayment), installation quality (seams, flashings, attachments), and material durability (gauge, alloy, coatings). Homeowners consider weather resilience to protect structure, reduce maintenance and repair costs, and limit insurance exposure. Interlock Metal Roofing systems are engineered for durability, hail protection, and wind resistance, but real-world performance relies on proper design and professional installation. Seattle’s wet winters create prolonged moisture exposure, so underlayment, drainage and corrosion-resistant coatings matter; request manufacturer specifications and installers experienced with Pacific Northwest conditions.
Metal roofing performance varies by metal type: steel, zinc, copper and aluminum each behave differently in moisture and salt exposure. Some metals naturally resist corrosion better; others need coatings or regular maintenance. Aluminum performs especially well in Seattle’s wet and coastal climate because it forms a protective oxide layer and resists rusting. Homeowners should consider corrosion resistance to protect long-term durability, reduce maintenance and preserve appearance and resale value—especially where frequent rain or salt spray accelerates deterioration. Interlock Metal Roofing systems use aluminum construction engineered for strong corrosion resistance. Interlock Metal Roofing Systems are further protected by the Alunar Coating System for extra protection, helping ensure a longer-lasting, lower-maintenance roof suited to the Pacific Northwest climate.
Metal roofs in Seattle, Washington are a durable, low‑maintenance choice. Although they resist rot, insects, and many weather effects, no roof is completely maintenance‑free. Homeowners should inspect roofs at least twice a year and after major storms—looking for accumulated debris, blocked gutters, loose or damaged flashing, and issues at penetrations (vents, chimneys, skylights). Remove branches, leaves, and sediment, and ensure fasteners remain tight and sealants intact. Seasonal debris from trees and heavy winter storms or wind-driven rain can cause localized damage or water backup if not addressed. With routine checks and prompt repairs, metal roofing offers long service life and reliable protection in Seattle’s climate.
In Seattle’s market, metal roofing can increase home value because buyers consistently value durable, low‑maintenance roofs that reduce future repair and labor costs. Premium roofing materials also enhance curb appeal, helping a home stand out on tree‑lined Seattle streets. A long lifespan boosts buyer confidence—investors and owner‑occupants often pay a premium for roofs that last decades. Architectural style matters by neighborhood: a modern standing seam suits some Capitol Hill or South Lake Union properties, while a textured profile may fit older Ballard or Queen Anne homes better. Interlock Metal Roofing systems offer multiple architectural profiles—slate, cedar shingle, Mediterranean tile, shake, and standing seam—available in heavy gauge aluminum and solid copper, allowing you to match style while delivering durability and resale value.
Yes. Interlock Metal Roofing Systems in Seattle are compatible with solar panels when fitted with custom solar brackets installed by Interlock Metal Roofing (PNW) Inc. Seattle’s persistent rain, high humidity and tendency for moss growth—plus occasional freeze–thaw stress—make long-lasting, well-sealed roofs especially important for solar longevity. Before adding panels, confirm roof age and expected lifespan; durable materials reduce the need to remove solar arrays for reroofing. If you’re comparing materials, prioritize long-lived metal systems like Interlock that are designed to support solar mounting solutions and plan for future solar when replacing your roof.

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!

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.

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!
