I price both of these systems constantly, so I get this question in one form or another almost every week. Homeowners want to know whether one is genuinely better, or whether it’s just a matter of taste. The honest answer is a bit of both — so let’s put them side by side and go deeper than any spec sheet will.

First, one thing to get out of the way: when I say “steel shingle” in this article, I mean a four-way locking steel shingle. That distinction turns out to matter a lot, and I’ll explain why below.

How each one actually keeps water out

Strip away the looks and this is the real difference between the two systems.

Standing seam is vertical sheets running the full length of the roof, from eave to peak. The trick is where the joint sits: the seam between two panels stands up one to two inches above the roof surface, depending on the profile, and the panels lock together up there. So the seam — the one place water could get in — is raised well above where water actually runs and pools. Water simply never reaches the joint.

Steel shingles get to the same place by a completely different route. A quality shingle is hooked on all four sides, not overlapped. On the sides, one edge is bent up and the mating edge is folded a full 180° back on itself, so the two pieces hook completely together. The bottom edge is formed with a hook too, and that hooks onto a top lock on the shingle in the course below. Every one of the four edges is mechanically locked.

Does one install better on a tricky roof?

Homeowners expect this to be a big differentiator, and honestly, it mostly isn’t. Both standing seam and four-way steel shingles can be installed on just about any roof feature out there — valleys, hips, dormers, chimneys, even round dormers. In fourteen years I can’t point to a roof shape and say “that one needs shingles” or “that one needs standing seam” on the basis of complexity alone.

There’s one practical wrinkle worth knowing. Standing seam panels come as full-length pieces — sometimes twenty-plus feet. Getting those to where they need to go can be the harder part of the job on a tight site. Shingles come in manageable individual pieces. It’s a logistics point, not a performance one, but it’s real.

The other place the two diverge is accents. When someone wants metal on just a porch, portico, or turret, that’s almost always standing seam — steel shingles rarely play the accent role.

Which handles winter better?

For most of what a Southwestern Ontario winter throws at a roof, these two are dead even. Both shed snow and ice quickly — no meaningful difference there. And both need snow guards where you’re protecting a walkway, a door, a driveway, or anything below the eave from a sudden slide. That requirement is the same for either system.

Snow guards on a metal shingle roof. Both systems shed fast and both need snow retention where people or property sit below.

The one edge goes to standing seam, and it’s the same edge that shows up everywhere else in this comparison: ice damming. Because standing seam can run on a much lower slope and is the more waterproof system when water backs up and sits behind an ice dam, it holds up better in the areas most prone to that. If you’ve got a stubborn ice-dam spot, that’s a point in standing seam’s favour.

What each costs — and exactly why

On new construction, the two systems price out pretty close. On a reroof, standing seam usually costs meaningfully more — and the reason is worth understanding, because it’s almost entirely about prep, not the metal itself.

A standing seam panel is flat, and it sits directly on the substrate. That means any unevenness underneath — the ridges and valleys of old shingles, a wavy deck — telegraphs right through that flat face and shows. So to run standing seam on a reroof, we either tear the old shingles off, or we double-strap and shim the roof to build a dead-flat plane, and add high-heat ice-and-water underneath. That’s real labour.

Steel shingles are formed, three-dimensional pieces that don’t lie flat against the deck. Their profile hides what’s underneath — so even with old shingles still down, the imperfections don’t show through the new steel. Less prep, lower labour, lower price.

Down the road: repairs and modifications

Say it’s fifteen years from now and a branch comes down, or you want to add a skylight. Can these be fixed? Yes — both of them, right in the middle of the roof. But I’ll be straight with you: it’s never fun. Nobody looks forward to opening up a finished roof, on either system.

Here’s the wrinkle most people don’t expect: ease of repair tracks the specific system, not just the standing-seam-vs-shingle category. Among standing seam, snap-lock is actually one of the easiest roofs to swap a panel on in the field — a genuine advantage it has over mechanical-lock standing seam, which takes more work to open up. And among shingles, the metal matters: an aluminum shingle comes out far more easily than a steel one. So “which is easier to repair?” doesn’t have a clean category winner — it depends on the lock type and the material.

So… is one of them just better?

People ask me this directly, and they almost always follow it with: “What do you have on your property?”

The answer: I have both — on my shop. It’s got metal shingles, with a substantial standing seam accent on the shed dormer. I didn’t crown one winner even there — I used each where it made the most sense. That’s not a dodge; that’s the honest reality of how good these two systems are.

But if you truly corner me and say “rank them” — if you ran both products through every identical test to see which failed first — I believe standing seam is probably the top-performing metal roof, and would likely outlast the shingle in more categories. I want to be clear about the size of that gap, though: it’s a photo finish. Steel shingles hold up great, with essentially no real-world problems. These are two excellent roofs — not one good one and one bad one.

The honest case for steel shingles

Since I gave standing seam the slight nod on paper, let me make sure the shingle gets a fair shake — because there are real, informed reasons to choose it.

The biggest one is the look, and it’s more than personal taste. A lot of homeowners look at standing seam and see a barn or an agricultural building — those vertical panel lines could also read “industrial” to them, and they don’t want their home to look that way. This is exactly where steel shingles shine: they give you a permanent, four-way-locked metal roof that doesn’t look like metal at all — it reads as a traditional shingle or shake. For the right house and the right homeowner, that’s the deciding factor, full stop.

On top of the look, you’ve got the two practical wins from earlier: on a reroof they usually cost less, and their profile hides an uneven deck that standing seam would put on display. So steel shingles aren’t a fallback. On the right house, they’re the smarter choice.

There’s one more honest point in the shingle’s favour: oil canning. Every standing seam roof oil-cans to some degree — that slight waviness you can catch across a flat panel in certain light. To be clear, it’s a natural characteristic of standing seam, not a defect, and we spell that out in writing on our contracts so nobody mistakes it for a flaw. But steel shingles essentially don’t oil-can, because the stamped profile breaks up the flat plane where it would show. If a perfectly smooth-looking roof matters to you, that’s a real mark in the shingle’s column.

How the decision actually gets made

When someone’s genuinely on the fence — same house, could go either way — the decision almost always lands on one of three things.

How to tell a quality install from a cheap one

This is the part I most want you to take away, because the difference between a roof that lasts 40–50 years and one that disappoints is usually the install, not the product name on the quote. Here’s what to ask and watch for on each system.

On standing seam: no exposed fasteners — anywhere

The entire point of standing seam is concealed fasteners. So the red flag is exposed fasteners where there should be a lock. I see homeowners who bought a “standing seam” roof that still has screws driven right through the panels — usually at the drip edge (where the panel should have a lock bent on the bottom and hooked onto the drip edge, instead of being run long and screwed through the face), and often at gables and valleys too.

Those are the most vulnerable areas on the whole roof — the bottom edge and the valleys, where water concentrates. A screw through the panel there defeats the purpose of the system. Ask any standing seam installer directly how they finish the eaves, gables, and valleys. The answer should be locks, not screws.

On steel shingles: confirm it’s four-way locking

Because “steel shingle” covers such a wide range of products, make sure you’re comparing like for like. A dramatically cheaper shingle quote is often the tell that it’s not a four-way lock — it might lock only top-and-bottom, only the sides, or just overlap on all four sides with exposed fasteners. Ask the question plainly: is this a four-way locking, concealed-fastener shingle? If it isn’t, that price difference isn’t a deal — it’s a different, lesser product.

The bottom line

Here’s how I send homeowners off. Drive around. Look at different roofs and different styles. Find the ones you actually love on real houses. And take your time with it — a metal roof is going to be up there for a very long time, so it’s not a decision to rush.

Because at the end of the day, both a true standing seam roof and a four-way locking steel shingle are going to be a great choice for most homes. Get the install right, pick the look you love, and you genuinely can’t go wrong between these two.

If you’re weighing a metal roof against asphalt shingles, there’s one thing I want you to understand before we get into anything else: a quality metal roof is going to cost more money than an asphalt shingle roof. That’s the honest starting point, and everything else in this comparison flows from it.

I’ve spent the last 14 years doing nothing but metal roofing, and before that I was installing asphalt shingles. So I’ve stood on both kinds of roofs, in every season we get here in Southern Ontario, and I’ve watched how both materials age over time. This isn’t a sales pitch. It’s what I’ve actually seen in the field — including the times asphalt makes sense and the myths about metal that just aren’t true.

Let’s start with the hard truth: metal costs more

I’d rather get this out of the way first than dance around it. If you want a quality metal roof, you’re going to pay more than you would for asphalt shingles — and there are a few different things stacking up to make that true.

The material itself costs more. Asphalt shingles are going to run you somewhere around a third of the cost of metal roofing, or even less. That’s a big gap, and it’s the first thing people notice when they start getting quotes.

You’re paying for a lot more labour. Roofing an average house with asphalt shingles is a lot faster than doing it in metal. A metal roof is far more man-hours. So you’re not just paying for more expensive material — you’re paying for the additional time and skill it takes to install it properly.

And there are specialty tools involved. A proper metal install requires equipment that an asphalt crew simply doesn’t need. Those tools, and the know-how to use them, are part of what you’re paying for.

So when you see that higher number on a metal roofing quote, that’s where the money is going. It’s not arbitrary. It’s more material cost, more labour, and the specialized work that goes into doing it right.

So what are you actually getting for that extra money?

Here’s the other side of the ledger — and this is where my 14 years really shape how I see it. When you invest in a quality metal roof, what you’re buying is peace of mind. Peace of mind that your roof is going to hold up to all the harsh weather we get, and that you’re not going to be calling somebody out to patch it.

If it’s a quality metal roof — quality paint, installed properly — you’re looking at a maintenance-free roof for 50-plus years. No babysitting it. No service calls. No wondering whether this is the year it finally starts leaking. That’s a fundamentally different ownership experience than an asphalt roof, and it’s the heart of why people make the switch.

Where metal really pulls ahead: the weather

People expect me to say metal wins on every weather front. The honest answer is more specific than that, and the headline is wind.

A quality metal roof installed properly has a much higher wind rating than an asphalt shingle roof. But here’s the part that really matters, and the part most comparisons skip over entirely: that wind rating doesn’t decrease over the life of the roof. An asphalt shingle’s wind resistance does. As shingles age, they get more vulnerable to wind — but a properly installed metal roof holds its wind performance for its entire life. That’s a huge difference when you live somewhere that gets the wind events we do.

There are also metal roofing options that stand up better to ice damming and the problems that come with it, and metal’s smooth surface sheds snow more readily than a shingle roof. But if I had to name the single biggest weather advantage metal has over asphalt, it’s wind — and the fact that the advantage doesn’t fade as the roof gets older.

How an asphalt roof actually ages (the part you don’t see from the ground)

To really understand this comparison, it helps to know how an asphalt shingle is built and what happens to it over time. I see it up close on roofs all the time, but a homeowner standing on the ground never does.

An asphalt shingle is built on a mat — that’s the base of the shingle, made of fiberglass. There are oils in that original mat. Then on top of the mat they apply the granules — the coloured granules everybody sees on the surface of the shingles.

What happens around the 10 to 15 year mark is those granules start to come off. You’ll start seeing more and more of them in your eavestroughs, washing down your downspouts. That’s the sign. That’s the last breath of your shingles. And once they start to deteriorate, it usually speeds up significantly.

Granule loss isn’t the only signal, either. As shingles reach the end of their life, they also start to curl and delaminate. So between the granules in your eavestrough and the curling on the roof, those are the visible signs that an asphalt roof is on its way out.

• Granules in the eavestroughs and downspouts — the protective surface is wearing off, usually starting around year 10 to 15.
• Curling and delamination — the shingles themselves are breaking down and lifting.
• Accelerating decline — once it starts, it doesn’t hold steady. It gets worse faster.

Compare that to metal, which doesn’t shed a protective surface the way asphalt does. There’s no granule layer to wear away, no mat to delaminate. That’s a big reason the maintenance-free lifespan is so different between the two.

Energy efficiency: two things most people don’t realize

Metal roofing helps with energy efficiency in a couple of different ways, and it’s worth understanding both because the second one tends to get missed entirely.

First, the paint. There are different paint systems out there, and they affect how much UV radiation and solar reflection you get off the roof. A quality reflective finish bounces more of the sun’s energy away instead of letting it soak in.

Second — and this is the one people overlook — the way a metal roof is formed. Because of its profile, a metal roof isn’t sitting flat and tight against the roof deck the way shingles do. That creates an air space between the metal and the deck, and that air space stops heat from transferring directly down into the attic. The result is a cooler attic, which helps with your cooling costs in the summer months.

So it’s not just “metal reflects heat” like you’ll read everywhere else. There’s the reflectivity of the coating, and there’s the air gap from how the roof is built — a structural advantage that has nothing to do with paint at all. Both work in your favour through our hot Ontario summers.

Who actually comes to us for metal

Most of our customers have already had numerous experiences with asphalt roofing. They’ve had it on their house — sometimes more than once — and they aren’t happy with how it performed or how it aged. They’re frustrated that they have to do it again.

That frustration is the throughline for the majority of the people we work with. The other big group is people building new custom homes who simply don’t want to be redoing their roof every 15 to 20 years. They’re thinking long-term from the start, and they don’t want a roof that puts them back in the shopping cycle a decade down the road.

Both groups are really telling me the same thing: they’re tired of the asphalt cycle, and they want out of it.

So when is asphalt actually the right call?

From a performance standpoint, there’s almost no application where asphalt suits a roof better than metal. So the honest answer really comes down to one thing: budget. If a metal roof doesn’t fit yours right now, asphalt is a perfectly reasonable choice, and there’s nothing wrong with that.

The one reason I’d push back on is the one I hear most: “I’m not staying in the house long enough to justify metal.” A metal roof adds resale value in a way an asphalt roof doesn’t, so that argument is weaker than it sounds. But if it comes down to dollars and metal isn’t in the cards today, asphalt will still put a solid roof over your head.

Common myths about metal roofs

After 14 years, there are a handful of misconceptions I find myself correcting over and over. If you’ve been hesitant about metal because of any of these, let me clear them up.

The bottom line after 14 years

Here’s my honest opinion, plain as I can put it. A metal roof might be the right choice for you if:

• You don’t want to deal with service calls on your asphalt shingles.
• You don’t want the hassle of shopping for a new roof every 15 to 20 years — something most people don’t get excited to shop for.
• You’re looking to make an environmentally friendly choice — a product that can be completely recycled at the end of its life, rather than asphalt shingles, which will almost certainly end up in a landfill.

If those things matter to you, and a metal roof fits your budget, then in my experience it’s the better roof — and it’s not particularly close. The higher upfront cost buys you decades of not thinking about your roof, better performance against the weather we actually get here, and a material you can feel good about. That’s the trade I’d make every time.
