Honolulu, HI Interlock Metal Roof Review — Energy Savings & ROI (Installed 2021)

Honolulu, HI

TL;DR: Honolulu Review Summary

This roofing installation in Honolulu is an Interlock roof installed several years ago. The homeowner’s original issue was a cold attic office even with heat; after installation the space stays warmer in winter and cooler in summer, reducing cooling costs. Although the roof cost more upfront, they say the payback more than covers the extra price and they would buy it again.

I had an Interlock roof put on several years ago and I am not sure I agree with the statement “more expensive, sure”.

While it does cost more to put on the roof, I think the payback more than covers the extra price.

I am sitting in my attic office, a place that got cold even with heat this time of year, it is warm now. It stays cooler in the summer as well which saves on cooling costs.

The sales person told me that it would be the case but I really didn’t believe it. I would buy this roof again in a heartbeat.

Top 10 Metal Roofing FAQs for Homeowners in Honolulu

Homeowners researching metal roofing in Honolulu 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 Honolulu 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 in Honolulu commonly last 50–75+ years; asphalt shingles typically last much less (often 15–25 years) before replacement. Honolulu’s tropical, mild climate with hot, humid summers and a wetter season from about October–April affects longevity—UV and heat can accelerate asphalt aging, while heavy winter rains and trade‑wind storms stress seams and fasteners. Coastal salt spray and persistent humidity increase corrosion risk for some metals and fasteners and make durable coatings and proper attachment essential during storms and high winds. For these reasons homeowners in Honolulu often choose metal or other high‑performance systems for long‑term resistance to moisture, UV, and wind. Interlock Metal Roofing systems use heavy‑gauge aluminum and are backed by a lifetime limited 50‑year transferable warranty designed for long‑term coastal protection.
In Honolulu, a metal roof generally costs more upfront than asphalt shingles, but total price varies widely. Final cost depends on roof size, slope, complexity (hips, valleys, penetrations), tear-off or reroof, flashing and skylight work, and labor rates. Local construction factors — salt‑air corrosion mitigation, high‑wind or hurricane fastening requirements, permit and disposal fees, and availability of experienced installers — also affect pricing. Many homeowners compare roofing options by lifetime value rather than initial price: metal roofs often have higher durability, longer warranties, and lower maintenance, which can reduce future repair and replacement expenses. A well‑specified metal system can save money over the roof’s service life even if initial costs are higher. Interlock Metal Roofing emphasizes long‑term ownership value and performance rather than competing as the lowest‑cost roofing option.
Honolulu’s tropical climate brings strong UV, heat and year‑round humidity, while proximity to the ocean exposes roofs to salt‑laden moisture and trade‑wind driven rain—both factors speed material breakdown. Lifespan: metal roofs commonly last 40–70+ years in coastal climates; asphalt shingles often last 15–25 years and degrade faster under intense UV and salt exposure. Maintenance: metal needs periodic inspections and fastener checks; asphalt needs more frequent repairs, replacement of flashing, and cleaning for algae/granule loss. Durability: metal resists wind uplift, corrosion (when coated), and UV better; shingles are more vulnerable to wind, granule erosion, and moisture-driven lift. Long‑term value: higher upfront cost for metal but lower lifecycle and replacement costs; shingles cost less initially but may require multiple replacements. Homeowners prioritizing durability and long‑term protection often choose metal. Interlock Metal Roofing appeals for its watertight interlocking panels, corrosion‑resistant coatings, and architectural curb appeal—well suited to Honolulu’s coastal conditions.
No — the idea that metal roofs are noisy in Honolulu, HI, is a common myth. Modern residential metal roofs installed over solid decking do not sound like barn roofs; the solid deck, underlayment and fasteners reduce vibration. Insulation, attic space and the overall roof assembly (underlayment, vents and ceiling) significantly affect sound transmission. Quality installation and proper fastening, sealing and flashing further minimize noise. Properly installed residential metal roofs are typically similar in sound to asphalt shingle or tile roofs. In Honolulu’s tropical climate, heavy rains are common, but properly designed systems control noise. Interlock Metal Roofing systems are installed as complete roofing systems designed for residential homes.
Yes—metal roofs can be energy efficient in Honolulu. Metal roofing reflects sunlight, especially when finished in light, high‑reflectance coatings, reducing solar heat gain. However overall energy performance depends on the roof assembly, insulation, and attic ventilation: a reflective metal panel over a poorly insulated or unvented assembly won’t deliver maximum savings. Honolulu’s tropical, sun‑intense, salty and humid climate increases the value of reflectivity and corrosion‑resistant materials but also makes proper ventilation and moisture control essential. Homeowners replacing roofs often consider energy efficiency to lower cooling bills, improve indoor comfort, extend HVAC life, and increase resale value. Such upgrades can also improve eligibility for local energy‑saving programs and utility rebates when paired with qualifying assemblies. Interlock Metal Roofing systems are designed to support long‑term home performance.
Q: How does metal roofing perform in Honolulu’s severe weather? Honolulu is exposed to Kona storms, strong wind gusts, heavy tropical rainfall, persistent salt spray and intense UV that accelerate roof aging. Properly engineered metal roofs resist high winds, shed heavy rain, and—when specified with impact‑rated panels or coatings—offer improved hail protection and long life compared with some roofing types. Performance depends on system design (profiles, clips, underlayment), installation quality (fastening, flashings, penetrations) and the material’s durability and finish. Homeowners prioritize weather resilience to reduce leaks, storm damage, maintenance and insurance risk. Interlock Metal Roofing systems are engineered for durability, hail protection and wind resistance, but benefits are realized only with correct product selection and professional installation.
Metal roofing performance depends on the type of metal used; some metals resist corrosion far better than others. In wet or coastal environments like Honolulu, aluminum performs especially well because it forms a protective oxide layer and resists saltwater corrosion. Homeowners should consider corrosion resistance when selecting roofing materials to protect structural integrity, avoid leaks and costly repairs, preserve curb appeal, and maintain warranty coverage in humid, salty climates. Interlock Metal Roofing systems use aluminum construction engineered for strong corrosion resistance and long-term durability. For added protection, Interlock Metal Roofing Systems are finished with the Alunar Coating System, which enhances resistance to salt, moisture, and oxidation, extending service life and reducing maintenance needs.
Metal roofing in Honolulu, Hawaii is generally considered a low‑maintenance, long‑lasting choice well suited to tropical conditions. However, no roof is completely maintenance‑free; periodic inspections—especially after storms or heavy trade‑wind events—are important. Homeowners should check for and remove debris, keep gutters clear, and inspect flashing and roof penetrations (vents, skylights, fasteners) for corrosion, looseness, or sealant failure. Salt air and seasonal leaf or palm frond buildup can accelerate wear or block drainage, so address accumulation promptly. Prompt attention after severe weather reduces risk of leaks and extends service life. Overall, metal roofs offer durable, low‑maintenance performance in Honolulu when paired with simple, regular inspections and cleaning.
Metal roofing can increase home value in Honolulu. Buyers prioritize durable, low‑maintenance roofs that reduce future repair costs, and premium materials boost curb appeal—especially in neighborhoods where architectural style matters. A metal roof’s long lifespan improves buyer confidence and can be marketed as a lasting investment. Interlock Metal Roofing systems provide a range of architectural profiles: slate, cedar shingle, Mediterranean tile, shake, and standing seam—allowing homeowners to match local styles while gaining metal’s durability. Systems are available in heavy‑gauge aluminum and solid copper, offering both performance and high‑end aesthetics. In Honolulu’s climate and style‑conscious market, the right metal roof can make a property more attractive to buyers and potentially increase resale value.

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.

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!
