The short answer: pick the roof that matches your plans
Neither metal nor asphalt wins for everyone in Calgary. Asphalt is the better buy for many homeowners who want a lower price today, while metal is the better buy for many who want to replace their roof once and stay put. The right choice comes down to how long you will own the home, how your roof is shaped and how you feel about hail, snow and upkeep.
Below are seven rounds, each covering one question Calgary homeowners actually weigh. Score each round for your own home, and the winner usually becomes obvious. If you want the full details on either material first, see our pages on metal roofing in Calgary and asphalt shingle roofing in Calgary.
Round 1: Up-front cost
Asphalt wins the up-front round easily. A shingle roof costs noticeably less to buy and install than a metal roof on the same house, and that gap is the single biggest reason most Calgary homes still wear shingles.
Metal costs more on day one for a few practical reasons. The panels themselves are a bigger material purchase, metal needs more custom trim at every edge, valley and wall, and installation takes specialized tools and experience. Complex roofs widen the gap, because every dormer or skylight means extra cutting and flashing work.
If your budget is fixed and the roof needs replacing now, this round may decide the match, and that is a perfectly sound reason to choose shingles.
Round 2: Lifespan and the long view
Metal wins the lifespan round. Asphalt shingles typically last about 15 to 20 years in Calgary, while a well-installed metal roof lasts decades.
The most useful way to think about this round is not years but roofs. Ask yourself how many roofs you will pay for while you own this house.
- Staying 8 to 10 years? With asphalt, you likely buy one roof and may sell before it needs replacing again. Metal’s extra lifespan mostly benefits the next owner.
- Staying 20 years? A shingle roof put on today may need replacing once more before you leave, possibly sooner if a hailstorm cuts its life short.
- Staying for good? You could pay for several shingle roofs over that time, each with its own tear-off, disruption and scheduling headache. A metal roof may be the last one you ever buy.
Strong UV at our elevation and freeze-thaw cycles wear shingles down, while metal does not lose granules or dry out the same way.
Round 3: Hail
Round three is closer than most people assume, and the answer depends on whether you care more about looks or function. Calgary sits in Canada’s most active hail belt, with most hail falling between June and August, so this round matters for every homeowner.
Hail damages the two materials in different ways:
- Asphalt bruises and cracks. A hard hit can crush the shingle mat, knock off granules and leave a weak spot that lets water in over time. That is functional damage, and it often leads to an insurance claim and a new roof.
- Metal dents. Large hail can leave visible dimples, especially on smooth, flat panels. In most cases the panel still sheds water, so the damage is cosmetic rather than a leak waiting to happen.
There is also a middle option. Class 4 impact-rated asphalt shingles carry the top UL 2218 rating and resist hail far better than standard shingles while keeping the familiar shingle look at a lower price than metal.
One warning before you score this round for metal: ask your insurer how cosmetic dents are treated. Policies vary, and some handle denting differently from damage that causes leaks.
Round 4: Snow, ice and chinooks
Metal takes the snow round on performance, but it brings a safety detail you have to plan for. Snow slides off a metal roof readily, while a shingle roof tends to hold its snow until it melts.
Shedding snow means less weight and less meltwater feeding ice at the eaves. The downside is where it lands: during a chinook, a whole slope can let go at once onto a front step, walkway or car. Snow guards placed above doors and walkways hold the snow back so it melts or releases in smaller amounts.
A shingle roof holds snow in place, which avoids the avalanche problem but gives ice dams more material to work with. When heat from the attic melts snow and the water refreezes at the cold eaves, ice can back water up under the roof covering.
Two things apply to both materials:
- Ice-and-water shield matters. A self-adhering membrane at the eaves and in the valleys is essential protection against ice dams, whether shingles or panels sit on top.
- Thermal movement is real. Chinooks can push Calgary above freezing, sometimes past 10°C, then drop back to deep cold. Metal expands and contracts with those swings and needs fastening that allows it to move, while shingles need a proper seal so warm-day winds do not lift them.
Round 5: Noise, looks and neighbourhood fit
This round is mostly a draw, and the tiebreaker is your taste and your street. The noise concern that steers many people away from metal is largely a myth for homes.
The loud metal roofs people remember sit over open framing on sheds. On a house, a solid deck, underlayment and an insulated attic dampen the sound.
Looks are where the real differences show:
- Asphalt suits almost any home style, from older bungalows to new two-storeys, and blends in on nearly every Calgary street.
- Metal comes in several profiles, from crisp standing seam panels to steel shingles that imitate a traditional roof, in a wide range of colours. Standing seam looks at home on modern builds and can look out of place on a traditional house.
Before you fall for a colour or profile, check whether your community has exterior guidelines. Some Calgary neighbourhoods and homeowner associations limit roofing materials or colours, so check with your association before you sign anything.
Round 6: Maintenance and repairs
Asphalt wins the repair round, while metal wins on day-to-day upkeep. That split matters more than it sounds.
Shingle repairs are easy and common. When wind lifts a few shingles, a roofer can replace just those pieces, though aging shingle roofs need such fixes more often.
Metal needs less routine attention, but repairs are more involved. A damaged panel needs a replacement matching the profile and colour, which gets harder years later if that colour is discontinued.
If you choose metal, the system type matters too:
- Concealed-fastener systems such as standing seam have no screws through the roof surface and need very little maintenance.
- Exposed-fastener systems rely on rubber washers under each screw. Those washers age, so fastener checks every few years are part of owning that kind of roof.
Round 7: Resale and how long you will stay
This final round goes to whichever material matches your timeline. Resale value is less about the material and more about whether buyers see a sound, recent roof.
If you sell within a few years of replacing, a new asphalt roof already ticks the box buyers and home inspectors care about most, and many buyers do not factor roof longevity into their offer.
If you stay a long time, the picture flips. A shingle roof installed today could be near the end of its life when you sell, while a metal roof would still have plenty of service left. Be honest about how long you will really stay.
The scorecard
Here is how the seven rounds shake out, and who each result favours.
| Factor | Asphalt | Metal | Winner for… |
|---|---|---|---|
| Up-front cost | Lower price today | Larger initial outlay | Tight budgets: asphalt |
| Lifespan | About 15 to 20 years here | Decades | Long-term owners: metal |
| Hail | Can bruise and crack | Can dent, often cosmetic | Depends on your insurer |
| Snow and ice | Holds snow in place | Sheds snow, needs guards | Snowy slopes over open yards: metal |
| Noise and looks | Quiet, fits any street | Quiet over a deck, bolder look | Your taste and community rules |
| Repairs | Quick, easy patches | Needs matching panels | Hands-off owners: metal |
| Resale | Sound roof for a quick sale | Long life for the next owner | Depends how long you stay |
Which one fits your home?
Most Calgary homeowners fall into one of a few patterns. These hypothetical profiles show how the rounds add up in real life.
A young family planning to move in 5 to 7 years
Asphalt is usually the right call. The family needs a dependable roof now and a sound one when they list. A quality asphalt shingle roof covers both, and the money saved can go toward other priorities. If hail worries them, an impact-rated shingle is a reasonable middle ground.
A retiree staying for good
Metal is a strong fit. Over a long stay, a retiree could otherwise face more than one shingle replacement, each with its own disruption. A metal roof with concealed fasteners keeps maintenance low, and snow guards over the front entrance and walkway keep sliding snow away from where they walk.
A hail-exposed home replacing after a claim
This one is close. If the owners plan to stay a long time and their insurer treats cosmetic dents fairly, metal can end the cycle of storm-driven replacements. If the insurer excludes cosmetic denting or the owners prefer a shingle look, Class 4 impact-rated asphalt gives strong hail resistance while staying with shingles. Either way, the insurer call comes first.
A modern build with simple roof lines
Metal often wins here. Long, uninterrupted slopes let standing seam panels run with few cuts, and the clean lines suit contemporary architecture. Asphalt still costs less, so the deciding question is how long the owners plan to stay.
