New Flat Roofs for Calgary Builds, Additions and Upgrades
Building in Calgary, Airdrie, Cochrane or Okotoks? After all, your roof is the one part of the build that has to handle hail, snow load and chinook freeze-thaw cycles from day one.
Iron Shield Roofing handles flat roof installation for commercial, multi-family and residential projects. We help you pick the right system for the structure, install it to the manufacturer's specifications and hand over a roof built to last for decades.
Why Build With a Flat Roof?
Flat and low slope roofs are the standard on commercial and multi-family buildings, and for good reasons:
- Usable Roof Space: Room for rooftop HVAC units, solar panels and equipment access
- Easier Upkeep: Flat surfaces are quicker and safer to inspect, clear and maintain
- Clean, Modern Look: Ideal for infill, mixed-use and contemporary home designs
- Long Service Life: Installed properly, a flat roof system can stay watertight for decades

Flat Roof Systems We Install in Calgary
We install flat roofs on new construction, additions and full roof upgrades across Calgary and area. Every system we offer has a proven track record on Alberta buildings.
However, the right choice depends on how the roof will be used, what sits on it and your budget. Here are the systems we recommend most often.
SBS MODIFIED BITUMEN (STYRENE BUTADIENE STYRENE) ROOFS
SBS modified bitumen is a two-ply or three-ply system of reinforced, rubber-modified asphalt membranes. The SBS polymer keeps the roof flexible in the cold and helps it absorb foot traffic and hail impacts.
As a result, it is watertight, tough and a reliable choice for Calgary commercial and multi-family buildings.
EPDM (ETHYLENE PROPYLENE DIENE MONOMER) ROOFS
EPDM is a reinforced synthetic rubber membrane that stays flexible from summer heat to deep winter cold. In other words, it moves with temperature changes instead of cracking.
For example, it is a cost-effective option for roofs with lots of penetrations and for buildings that see heavy snow and spring melt.
PVC (POLYVINYL CHLORIDE) ROOFS
PVC is a single-ply membrane with heat-welded seams. It resists grease, oils and many chemicals, which makes it a strong pick for restaurants and buildings with exhaust equipment.
On top of that, it is reflective and fire-retardant, and it can be supplied in colours where the roof is visible.
TPO (THERMOPLASTIC POLYOLEFIN) ROOFS
TPO is a single-ply membrane with heat-welded seams and a reflective white surface. It resists tears, punctures and impacts, and it helps keep buildings cooler in summer.
For this reason, it is a popular, cost-effective choice for large commercial roofs, and the membrane is recyclable.
TAR AND GRAVEL (BUILT-UP) ROOFS
Built-up roofs layer asphalt and felts with a gravel surface. The system has a long track record on older commercial buildings.
On new projects, however, we usually recommend a modern membrane, but we can match or repair built-up systems where needed.
Projects of Any Size
From a garage or small addition to a large commercial or multi-family building, we have the crew and the equipment to get it done. Even complex roofs with multiple levels, heavy equipment or tight sites are part of the job.
Quality Materials, Fair Pricing
For example, we install SBS modified bitumen, EPDM, PVC, TPO and built-up systems, and then we work with your project team to choose the one that fits the building, the budget and the timeline.

Flat Roof Installation in Calgary: Frequently Asked Questions
Common questions about new flat roofs on Calgary buildings.
What is the best flat roof system for a new building in Calgary?
It depends on the building. Two-ply SBS is very tough and hail-resistant, TPO is reflective and cost-effective on large roofs, and EPDM is flexible and handles lots of penetrations. We recommend a system once we know the building, its use and the budget.
How long does a new flat roof last?
A properly installed SBS, TPO or EPDM roof typically lasts 20 to 30 years. Good drainage and regular maintenance help it reach the top of that range.
Do you work with general contractors and developers?
Yes. We price from drawings and specifications, coordinate with your schedule and work alongside the other trades on site.
Can you install a flat roof on a house or garage?
Yes. We install membrane roofs on garages, additions, porches and modern homes with low slope roofs.
Is the quote free?
Yes. Quotes for new roofs and replacements are free.
