If you’re replacing a roof in Airdrie, the choice between metal and asphalt shingles usually comes up sooner or later. Maybe a neighbour went metal after the last hailstorm, or you’re on your second shingle roof in the same house and wondering if there’s a way off the treadmill. Both materials are proven here. What separates them isn’t which one is “better” in general, but how each one behaves in Airdrie’s specific mix of hail, prairie wind, heavy spring snow and chinook swings — and how long you plan to live with the result. This article compares them head to head on those points, so you can see which trade-offs you’re more comfortable with.
The quick answer
Metal is the stronger choice if you plan to stay in the home for a long time, your roof has fairly simple slopes, and you’d rather pay once than replace shingles every couple of decades. Asphalt — especially Class 4 impact-resistant shingles — is the stronger choice if you might sell in the next several years, your roof is complex, your budget is tight today, or your insurance policy treats cosmetic damage on metal unfavourably.
Most of the rest of this article is about why, and about the grey zone between those two answers.
How each one handles hail
Airdrie sits in Alberta’s hail corridor, the stretch from High River through Calgary to Red Deer where summer afternoon storms build over the foothills and roll east. The June 13, 2020 storm that hit Calgary, Airdrie and Rocky View County caused about 1.2 billion dollars in insured damage, among the costliest natural disasters in Canadian history at the time. Hail is the first thing to think about with any roof here.
Asphalt shingles bruise. A hailstone hitting a standard shingle can crack the mat underneath and knock granules loose, leaving a soft spot. The shingle may not leak right away, but the bruise ages faster in the sun and eventually fails. That’s functional damage, and it’s why so many Airdrie roofs get replaced after a big storm.
Metal dents. Hail rarely punches through a residential steel roof. The typical result is a dent that doesn’t affect how the roof sheds water. The roof keeps working — but the dent is visible, and it’s permanent.
Those two failure modes matter differently depending on who’s paying. With shingles, a bad storm usually means a claim and a new roof. With metal, a bad storm often means a roof that still works but looks dimpled. Thicker steel and textured or stone-coated finishes dent less and hide dents better than thin, smooth panels, which is why gauge and finish are worth paying attention to here.
The cosmetic-damage clause: read it before you choose
This is the part many homeowners only discover after a storm. Some insurance policies include a cosmetic-damage exclusion or endorsement for metal roofs. In plain terms, if hail dents the metal but the roof still keeps water out, the policy may not pay to replace it. Policies vary, and some insurers don’t use these clauses at all.
Before committing to metal, it’s worth asking your broker three direct questions:
- Does my policy cover cosmetic hail damage on a metal roof, or only damage that lets water in?
- Would switching to metal change my premium, up or down?
- Is there a credit for an impact-rated roof, and what documentation do you need?
If cosmetic denting isn’t covered, a textured steel profile that hides dents becomes more attractive. If it is covered, smooth standing seam is a less risky choice. And if your insurer offers a meaningful credit for Class 4 roofs — some Alberta brokers report credits up to 25 to 30 percent of the roof or dwelling portion, never automatic and varying by insurer — that can tilt the math toward impact-resistant shingles.
Wind on the open prairie
North and northwest winds cross the prairie into Airdrie with no natural barrier, and homes on the city’s edges feel it most.
Asphalt fails in wind at the edges first. Shingles lift along the rakes and ridges, the seal breaks, and the next gust tears them off. The fixes are well known: a starter strip along the rakes as well as the eaves, high-wind nailing, and hand-sealing edge courses when the roof goes on in cool weather before the sun can bond the sealant strips.
Metal is very wind-resistant when it’s fastened to the manufacturer’s specification — correct clip or fastener spacing and properly secured edge and ridge trim. When metal fails in wind, it’s almost always because trim or fasteners weren’t installed to spec.
In both cases, installation quality decides wind performance more than the material itself. A metal roof installed carelessly won’t outperform a carefully installed shingle roof.
Snow, chinooks and falling sheets of snow
Airdrie’s heaviest snow often comes in March and April — wet, dense and heavy. Chinooks add a twist: warm spells melt roof snow, then it refreezes at the roof edge and builds ice dams.
Metal sheds snow. On a steep enough slope, snow slides off, especially when a chinook warms the panels. That means less weight on the roof and less chance of ice dams forming at the eaves. The catch is where it lands. A sheet of snow can drop onto a front step, a walkway, a deck, a parked car or a lower roof with real force. Snow guards — small brackets or rails that hold snow in place so it melts off gradually — are an essential part of a metal roof over any of those areas.
Shingles hold snow. The textured surface keeps snow in place, which is safer below but means more weight and a higher chance of ice damming if attic ventilation and insulation aren’t right. Ice-and-water membrane along the eaves and in the valleys is the defence either way.
Noise: mostly a myth on houses
The idea that metal roofs are loud comes from barns and sheds, where panels are screwed to open framing with nothing underneath. On a house, metal goes over a solid deck and underlayment, with an insulated attic between the roof and the living space. Rain and hail sound on a residential metal roof is usually close to that of a shingle roof. If you’re sensitive to it, it’s a reasonable thing to ask about for a room with a vaulted ceiling directly under the roof, where there’s less attic space to absorb sound.
Lifespan in Airdrie’s climate
This is where the two materials are furthest apart.
- Asphalt shingles typically last 15 to 20 years in Airdrie. The 20 to 25 years often quoted nationally is optimistic here, because hail, strong UV, constant wind and freeze-thaw all wear shingles faster. Builder-grade shingles often don’t reach 15.
- Metal roofs are commonly expected to last 40 to 60 years. The paint finish may need attention before the steel itself does.
Put simply: over the time most people own an Airdrie home, asphalt means one or more replacements; metal often means none.
Lifetime cost: think in roofs, not square feet
On the day it’s installed, metal costs roughly twice as much as asphalt. The better way to compare is to count how many roofs you’ll pay for while you own the home. The Airdrie roofing cost guide lays out current price ranges by material; here’s the decision logic, by ownership horizon:
| If you stay… | Asphalt path | Metal path | Which usually comes out ahead |
|---|---|---|---|
| 5 years | One roof | One roof, higher cost | Asphalt |
| 15 years | One roof, possibly nearing the end | One roof, most of its life left | Close; depends on resale |
| 25 years | Two roofs (one mid-ownership) | One roof | Leaning metal |
| 40 years | Two to three roofs | One roof | Metal |
As a rough illustration, a standard shingle replacement on a typical Airdrie two-storey might run around $11,000 to $13,000, while steel shingles on the same house might be about $24,000 to $30,000 (2026 Airdrie market estimates, not quotes). The shingle path wins if you sell soon; the metal path wins if you’d otherwise pay for that shingle roof twice. Labour and material costs tend to rise over time, which quietly favours paying once. Financing can also change the picture if the up-front cost is the only obstacle.
Resale and what the street looks like
Airdrie buyers notice a newer roof. They rarely pay a large premium for one material over another, but a metal roof with plenty of life left is an easy selling point, especially to buyers who’ve been through a hail claim before.
Looks matter in newer subdivisions. Many have architectural guidelines or restrictive covenants from the developer, and some homeowners’ associations set rules on roofing materials, profiles or colours. Steel shingles and stone-coated steel read as a traditional roof from the street and are more likely to fit in; standing seam has a more modern look that might need approval. Check your title documents or community association before settling on a profile.
When Class 4 asphalt is the smarter middle ground
For a lot of Airdrie homeowners, the real decision isn’t metal or standard shingles — it’s metal or Class 4 shingles. Class 4 impact-resistant shingles pass the UL 2218 test, in which a 2-inch steel ball is dropped twice on the same spot without cracking the shingle. They look and install like regular shingles, cost noticeably less than metal, and resist the hail that bruises standard shingles.
Class 4 asphalt is often the better choice when:
- You expect to sell within roughly 10 to 15 years
- Your roof has many valleys, dormers, skylights or a chimney, where metal detailing gets expensive
- Your insurer offers a credit for impact-rated shingles, or excludes cosmetic damage on metal
- Your community’s guidelines favour a conventional shingle look
- The up-front budget simply doesn’t stretch to metal
No shingle is hail-proof, and a Class 4 roof still has the shorter asphalt lifespan. But it closes much of the hail gap at a fraction of metal’s cost. You can read more about standard and impact-rated options on the asphalt shingle roofing page.
Choosing: a short checklist
Metal leans your way if most of these are true:
- You plan to stay 20 years or more
- The roof has long, simple slopes
- Your lot is exposed and you’re tired of wind repairs
- Your insurance treats cosmetic denting fairly, or you choose a textured profile
- You can plan snow guards over entrances, walkways and lower roofs
Asphalt (ideally Class 4) leans your way if most of these are true:
- You might move within 10 to 15 years
- The roof is complex, with lots of flashing details
- You want the lowest up-front cost
- Your community prefers a conventional shingle look

Final thought
Neither material is a mistake in Airdrie when it’s chosen for the right reasons and installed properly. Metal rewards long ownership and simple rooflines; asphalt, especially Class 4, rewards flexibility and a lower starting cost.
