Top 10 Metal Roofing FAQs for Homeowners in London

Homeowners researching metal roofing in London 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 London 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 conventional asphalt shingles usually have shorter service lives (often 15–30 years). London, ON has cold, snowy winters with lake-effect snow and regular freeze–thaw cycles plus about 1,000 mm of annual precipitation—conditions that increase the importance of corrosion resistance, secure fastening and good drainage for long-lived roofs. Snow loads, ice dams and repeated freeze–thaw stress can shorten asphalt roofs but are handled well by metal systems when installed properly. Homeowners choose metal for durability, lower maintenance, wind and snow shedding, and long warranties. Interlock Metal Roofing systems use heavy-gauge aluminium and carry a lifetime limited 50-year transferable warranty designed to provide long-term protection in London’s climate.
Metal roofing in London, ON generally costs more up‑front than asphalt shingles, but total price varies widely with roof size, slope, complexity (dormers, valleys), tear‑off, flashing, skylights and local labour. London’s humid continental climate brings cold, snowy winters with frequent freeze–thaw cycles and seasonal snow loads, plus warm humid summers that encourage moss and biological growth — these factors can raise installation requirements and material choices for longevity. Many homeowners weigh lifetime value over initial price: a durable metal system typically lowers future repair and replacement costs compared with cheaper options. Local construction factors (snow guards, heavier underlayment, corrosion‑resistant fixings) influence cost. Interlock Metal Roofing focuses on long‑term ownership value and durability rather than competing as the lowest‑cost roofing option.
In London, ON, cold winters with repeated freeze–thaw cycles and regular snow loads are key local factors affecting roofs. Metal roofing typically lasts 40–70+ years versus 15–25 years for asphalt shingles. Maintenance for metal is usually low (occasional debris clearing, fastener checks); asphalt needs more frequent repairs, moss/ice-dam management and periodic replacement. Durability: metal resists freeze–thaw cracking, sheds snow and tolerates wind and hail better; asphalt can lose granules, curl and trap moisture over time. Long-term value: metal’s higher upfront cost is often offset by longer life, lower maintenance and fewer replacements, while asphalt is cheaper initially but costs more over decades. Homeowners in London who prioritise durability and long-term protection often choose metal; those focused on lower upfront cost may prefer shingles. Interlock Metal Roofing appeals here because interlocking panels improve watertightness, snow shedding and wind resistance while delivering lasting performance and strong architectural curb appeal.
This is a common myth: modern residential metal roofs in London, ON are not the noisy, tin‑shed roofs many picture. When installed over solid decking, with proper underlayment and insulation or an attic cavity, metal roofing sounds very similar to asphalt shingle or tile. Sound depends on the full roof assembly—insulation, ventilation and the presence of an attic reduce rain noise—and on installation quality; loose fastening or missing underlayment can increase perceptible sound. Properly installed residential metal roofing typically performs comparably to other materials. Interlock Metal Roofing systems are supplied and fitted as complete residential roofing systems, engineered to include the decking, underlay and details needed to control noise and weatherproof homes.
Metal roofing can reflect sunlight, lowering attic temperatures in London, ON’s warm summers and reducing cooling loads. Overall energy performance also depends on the roof assembly, insulation levels and ventilation—proper insulation and airflow are essential to retain heat in winter and avoid moisture issues. Climate matters: with London’s hot, humid summers and cold winters, reflective metal helps in summer but effective insulation and air‑sealing remain critical for winter efficiency. Homeowners replacing roofs often prioritise energy efficiency to cut utility bills, improve year‑round comfort, reduce greenhouse gas emissions, and boost resale value or qualify for incentives. Colour and finish choices also influence reflectivity and aesthetic preferences. Interlock Metal Roofing systems are designed to support long‑term home performance.
London, ON faces thunderstorms, strong winds, hail, freezing rain/ice, heavy rain and snow and freeze–thaw cycles that can stress roofs. Metal roofing can resist high winds, shed snow and rain, and generally withstand impact better than many ageing asphalt roofs; properly profiled and installed metal also reduces ice‑dam water infiltration and hail damage risk. Performance depends on roofing system design (profile, underlayment, fastening), installation quality, and material durability/gauge—poor design or workmanship undermines any product. Homeowners prioritise weather resilience to avoid leaks, lower repair frequency, protect home value and reduce insurance exposure. Interlock Metal Roofing systems are engineered for durability, improved hail protection and tested wind resistance, making them a weather‑resilient choice for London homeowners and can lower long‑term maintenance costs.
Metal roofing performance depends on the base metal and coatings used. Some metals (such as stainless steel and aluminium) are inherently more resistant to corrosion than plain steel, especially in wet, humid or coastal environments. Aluminium performs particularly well in these conditions because it forms a protective oxide layer and resists rusting. Homeowners should prioritise corrosion resistance when selecting roofing materials because it affects lifespan, maintenance costs, leak prevention, aesthetic longevity and resale value—more resistant systems require less upkeep and avoid premature replacement. Interlock Metal Roofing Systems use aluminium construction engineered for strong corrosion resistance and are further protected by the Alunar Coating System for extra durability and long-term protection.
Metal roofing in London, Ontario is a durable, low‑maintenance choice for homes. While metal roofs require less upkeep than asphalt shingles, they are not completely maintenance‑free. Homeowners should inspect roofs at least twice yearly and after major weather events, looking for loose fasteners, damaged flashings and sealant around chimneys, vents and skylights. Clear debris from panels and valleys, keep gutters and downspouts free‑flowing, and check penetrations (vents, pipes, solar mounts) for secure seals. Seasonal leaves, ice build‑up, wind‑driven branches and heavy rain can affect coatings, fasteners and flashings, so address issues promptly. With periodic checks and quick repairs, metal roofing offers long life and reliable protection.
In London, ON, metal roofing can increase home value because buyers often prioritise durable, low-maintenance roofs that reduce future repair costs and insurance concerns. Premium roofing materials also enhance curb appeal, helping a property stand out in resale markets. A long lifespan—often decades—gives buyers confidence in fewer near-term replacements and stronger perceived value. Architectural style matters by neighbourhood: a modern standing seam may suit new developments, while slate- or cedar-look profiles fit older streetscapes. Interlock Metal Roofing systems offer multiple architectural profiles — slate, cedar shingle, Mediterranean tile, shake and standing seam — and are available in heavy gauge aluminum and solid copper, letting homeowners choose a finish that complements local character while delivering long-term performance.
Yes — Interlock Metal Roofing systems can accept solar panels in London, ON. London’s snowy winters and frequent freeze–thaw cycles (plus humid, shaded summers that encourage moss growth) affect roof choice and mounting longevity, so choose durable materials that resist moisture and thermal movement. Interlock Metal Roofing Systems are solar compatible and designed to support solar mounting solutions, and Interlock Metal Roofing (Ontario) Ltd. can install custom solar brackets for secure attachment. When comparing roofing materials, prioritise lifespan — a long‑lasting roof reduces the chance of removing panels for a reroof. If you plan solar in future, factor that into your roof replacement now to save cost and ensure proper mounting.

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.

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!
