Top 10 Metal Roofing FAQs for Homeowners in Tacoma

Homeowners researching metal roofing in Tacoma 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 Tacoma 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 15–30 years. Tacoma’s climate is wet and mild — average annual rainfall is around 40–42 inches, concentrated in fall and winter, and snowfall is minimal — only a few inches most years. Local factors that matter: persistent rainfall and coastal moisture promote corrosion risks under failing coatings and encourage moss/lichen growth on porous asphalt roofs, while limited snow load reduces structural concerns. Because of high winter moisture and occasional wind-driven rain, homeowners often choose durable metal systems for long service life, lower maintenance, and better resistance to moss and rot compared with asphalt. Interlock Metal Roofing systems use heavy‑gauge aluminum and carry a lifetime limited 50‑year transferable warranty designed for long‑term protection.
Metal roofs in Tacoma generally cost more upfront than asphalt shingles but often deliver longer service life and lower lifetime maintenance. Final price depends on roof size, slope and complexity, tear-off and disposal, flashing and skylights, plus local labor and permitting. Tacoma averages about 41 inches of rain annually. Frequent coastal moisture and the Pacific Northwest’s tendency for moss on shaded roofs can increase installation details (venting, underlayment, fasteners) and maintenance needs, which affects cost and warranty choices. Many homeowners therefore compare options on lifetime value rather than initial price: a durable metal system can reduce future repair and replacement costs. Interlock Metal Roofing focuses on long-term ownership value and performance rather than competing as the lowest-cost roofing option.
Tacoma’s wet, mild climate—with about 41 inches of annual rain and persistent coastal humidity that encourages moss and algae—strongly affects roof choices. Lifespan: metal roofs commonly last 40+ years; asphalt shingles typically 15–30 years. Maintenance: metal needs less routine cleaning and resists moss; asphalt in Tacoma’s damp conditions will require more frequent cleaning, spot repairs, and earlier replacement. Durability: metal better resists moisture, rot, and wind uplift, while asphalt can suffer granule loss, curling, and moss-related damage. Long-term value: metal has higher upfront cost but lower life‑cycle cost for homeowners wanting long-term protection; asphalt has lower initial cost but higher replacement frequency. Homeowners who prioritize durability and long-term protection often choose metal. Interlock Metal Roofing systems appeal in Tacoma because interlocking panels resist water intrusion, reduce moss retention, and deliver lasting performance with strong architectural curb appeal.
Tacoma’s wet climate—about 41 inches of rain annually—and Puget Sound’s steady moisture that promotes roof moss can affect roof performance, not noise. This is a common myth: modern residential metal roofs installed over solid decking with proper underlayment and insulation don’t sound like barn metal. Attic space, insulation, and the full roof assembly (decking, underlayment, ventilation) influence how rain sounds, and installation quality matters. For Tacoma homeowners, good ventilation and moss control help maintain performance and sound over time. Properly installed residential metal roofs are typically similar in sound to asphalt or tile. Interlock Metal Roofing systems are installed as complete roofing systems designed for residential homes.
Yes — a metal roof can be energy efficient in Tacoma. Metal panels reflect sunlight, lowering attic heat gain on sunny days, but overall performance depends on the full roof assembly: quality insulation, a continuous air barrier, and good attic ventilation are critical to realize savings. Tacoma’s frequent rain and coastal humidity — which encourage moss and persistent moisture — make metal’s durability and moisture resistance important for long‑term performance. Because Tacoma has mild summers and modest cooling loads, reflectivity helps but airtight insulation and ventilation often deliver equal or greater benefits. Homeowners researching replacements consider energy efficiency to reduce bills, improve year‑round comfort, and increase resale value. Interlock Metal Roofing systems are engineered to support those long‑term performance goals.
Q: How will metal roofing hold up in Tacoma severe weather? Tacoma gets roughly 40 inches of rain per year with cool, wet winters and relatively dry summers, so roofs face persistent moisture and coastal dampness that encourage moss and algae growth. Humidity and frequent cloudy, wet conditions also raise long-term corrosion and biological-growth concerns for roof surfaces. Metal roofing performs very well in wind, hail, and heavy rain when the system is properly specified and installed: it sheds water fast, resists rot and moss better than shingles, and can be engineered for high wind and impact resistance. Performance depends on: • roofing system design • installation quality • material durability Homeowners weigh weather resilience to lower maintenance, reduce leak risk, and protect investment. Interlock Metal Roofing systems are engineered for durability, hail protection, and wind resistance.
Metal roofing corrosion depends on the metal type—steel, galvanized/ Galvalume, and aluminum perform very differently. Tacoma’s wet, maritime climate with frequent rain increases corrosion risk, and constant moisture plus shade encourages moss growth on roofs—both affect longevity and maintenance needs. Aluminum resists rust and salt‑air corrosion best in these conditions, while untreated steel is more prone to corrosion. Homeowners should prioritize corrosion resistance to reduce maintenance, prevent leaks, and extend service life when comparing materials. Interlock Metal Roofing systems use aluminum construction for strong corrosion resistance and are further protected by the Alunar Coating System for added durability.
Metal roofing is a durable, low‑maintenance choice for Tacoma homeowners comparing materials. Tacoma gets rain year‑round, concentrating in fall and winter, which raises moisture exposure for roofs. Coastal moisture and shaded conditions also encourage moss and algae on roof surfaces, so keep that in mind. No roof is completely maintenance‑free: inspect roofs periodically (after storms and seasonally), remove debris, keep gutters clear, and check flashing, fasteners, and penetrations (vents, skylights). Windstorms and seasonal debris can trap moisture and stress flashings. Overall, metal performs very well in Tacoma’s wet, moss‑prone climate and is a strong, low‑maintenance option when paired with routine inspections.
In Tacoma’s rainy, maritime climate—with roughly 40–45 inches of annual precipitation and high humidity—roofing must resist constant moisture and moss growth, especially in fall and winter months. Buyers here value durable, low‑maintenance roofs that stand up to coastal moisture, so metal roofing can increase resale appeal. Premium materials boost curb appeal and fit well in many neighborhoods, though architectural style matters for some blocks. Metal’s long lifespan and corrosion-resistant options improve buyer confidence versus short‑life alternatives. Interlock Metal Roofing systems offer profiles that mimic slate, cedar shingle, Mediterranean tile, shake, and standing seam, and are available in heavy‑gauge aluminum and solid copper—providing design flexibility when comparing materials for Tacoma homes.
Yes—Interlock Metal Roofing Systems are compatible with solar installation when custom solar brackets, installed by Interlock Metal Roofing (PNW) Inc., are used. The systems are designed to support solar mounting solutions. In Tacoma’s rainy, maritime climate—with roughly 40–42 inches of annual precipitation and conditions that encourage moss growth—roof longevity and secure, waterproof attachments matter. Before adding panels, confirm roof lifespan; long‑lasting materials (like Interlock metal) are preferred so you won’t need to remove panels for an early reroof. If you’re comparing materials, plan for future solar when replacing your roof to avoid extra costs and ensure compatible mounting. Interlock can provide site‑specific mounting details during quoting.

Edmonton, AB Interlock Metal Roofing Review (Installed 2014)

April 26, 2026

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)

April 24, 2026

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)

April 23, 2026

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)

April 22, 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

April 19, 2026

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)

April 15, 2026

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.

Interlock Metal Roofing Review in Saint Paul, AB — 50-Year Warranty (Installed 2025)

April 14, 2026

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!

Interlock Metal Roof Review - Burnaby, BC Metal Roofing (Installed 2024)

April 13, 2026

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)

April 12, 2026

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)

April 11, 2026

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!
