Commercial Roofing in Calgary
Flat roof replacements, repairs and maintenance for commercial, industrial and multi-family buildings across Calgary.
Flat Roof Systems, Repairs and Maintenance for Calgary Commercial Buildings
A commercial roof protects everything under it: inventory, equipment, tenants and the people who work there. When it fails, the cost goes well past the repair bill. Iron Shield Roofing installs, repairs and maintains commercial roofs across Calgary, from single-storey retail units to large warehouses and multi-building condo sites.
Every project starts with a roof assessment and a written scope, so you know what is being done, why it matters and what it costs before any work begins. Our crews work around your business hours and keep the site clean, safe and watertight every night.
Commercial Roofing for Calgary Property Owners and Managers
Property managers, building owners and facility teams call us when they need a roofer who shows up, communicates and finishes on schedule. We handle new installations, full replacements, leak repairs and planned maintenance, and we put our findings in writing with photos so you can share them with owners, boards or insurers.
Calgary weather is hard on roofs. Large hail, high winds and frequent chinook thaws stress seams, flashings and drains. We build every roof with those conditions in mind.
Commercial Roofing Services in Calgary
We work on commercial buildings throughout Calgary and nearby communities, including Airdrie, Cochrane, Okotoks, Chestermere and Rocky View County. Whether you have one building or a portfolio, we can set up an inspection and maintenance plan that keeps small problems from becoming expensive ones.
Below are the core commercial roofing services we provide. Call (403) 471-9023 to book a site visit.
Commercial Roof Inspections
Flat roofs rarely show damage from the ground. Water can travel under a membrane for metres before it shows up as a stain on a ceiling tile. A professional inspection finds open seams, blistering, ponding, failed flashings and blocked drains while they are still cheap to fix. We provide photo reports with clear repair priorities, which help with budgeting and insurance claims.
Commercial Roof Maintenance
Scheduled maintenance is the easiest way to get more years out of a commercial roof. Our maintenance visits include clearing drains and scuppers, resealing penetrations, checking rooftop unit curbs, removing debris and documenting the roof condition. Spring and fall visits catch damage from Calgary winters and summer hail before it turns into a leak.
Commercial Roof Repairs
Leaks get worse the longer they sit. We trace the source, repair the membrane or flashing and confirm the area is watertight. Common Calgary repairs include hail punctures, wind-lifted seams, cracked flashings around rooftop units and failed drain connections. When a repair is not the right call, we will tell you and explain why.
Commercial Roof Replacements
Every roof reaches the end of its service life. When repairs start costing more than they save, a replacement is the better investment. We remove the old system, correct insulation and drainage issues, and install a new membrane or metal roof matched to your building. Replacements are phased and scheduled to keep your operations running.
Types of Commercial Roofing
Commercial buildings in Calgary use a wide mix of roof systems, and the right choice depends on the roof slope, building use, budget and how long you plan to own the property. Iron Shield Roofing installs and repairs both flat and sloped commercial roofs on warehouses, offices, retail centres, restaurants, churches and multi-family buildings.
We walk you through the options, explain the trade-offs in plain terms and recommend the system that fits your building and goals.
Commercial Sloped Roofing
Sloped roofs are common on smaller commercial buildings, mixed-use properties and multi-family sites. We install and replace asphalt shingles, synthetic and rubber shingles, metal and tile systems, with proper underlayment, ventilation and flashing details for Calgary conditions.
For buildings that see heavy hail, ask us about impact-rated products built to take more punishment.
Asphalt Shingle Roofs
Asphalt shingles are the most common sloped roof in Alberta. They are affordable, come in many colours and are easy to repair. Impact-rated shingles are a strong choice for hail-prone Calgary properties.
F-Wave Synthetic REVIA Shingle Roofs
F-Wave REVIA synthetic shingles are made from polymer blends that resist cracking, wind uplift and hail. They are lightweight, look like traditional shingles and carry long manufacturer warranties.
Euroshield Rubber Shingle Roofs
Euroshield shingles are made from recycled rubber and designed to look like slate or shake. The rubber absorbs hail impact instead of cracking, which makes it a good fit for Calgary weather.
Composite Designed Shake And Slate Roofs
Composite shake and slate gives you the look of natural materials without the weight or upkeep. These products resist rot, splitting and impact damage, and they work well on high-end commercial and multi-family buildings.
Cedar Shake And Shingle Roofs
Cedar shakes and shingles offer a natural, classic look. They need more maintenance than synthetic options, but when installed and cared for properly they provide decades of service.
Concrete And Clay Tile Roofing
Concrete and clay tiles are heavy, durable and fire resistant. The roof structure has to be checked before installation, and we confirm load capacity before recommending tile for your building.
Commercial Flat Roofing
SBS MODIFIED BITUMEN (STYRENE BUTADIENE STYRENE) ROOFS
SBS modified bitumen is a two-ply system with a base sheet and a granulated cap sheet. It stays flexible in deep cold, handles foot traffic well and has a long track record on Alberta commercial roofs.
EPDM (ETHYLENE PROPYLENE DIENE MONOMER) ROOFS
EPDM is a synthetic rubber membrane that stays flexible across a wide temperature range. It is installed in large sheets with few seams, which reduces leak points, and it is a cost-effective option for many low slope buildings.
PVC (POLYVINYL CHLORIDE) ROOFS
PVC membranes have heat-welded seams that are stronger than the sheet itself. PVC resists chemicals, grease and standing water, which makes it a good choice for restaurants and buildings with rooftop exhaust.
TPO (THERMOPLASTIC POLYOLEFIN) ROOFS
TPO is a single-ply membrane with heat-welded seams and a reflective white surface that helps lower cooling costs. It is one of the most widely installed commercial flat roof systems in Canada.
TAR AND GRAVEL (BUILT-UP) ROOFS
Tar and gravel, or built-up roofing, uses layers of asphalt and felt topped with gravel. Many older Calgary buildings still have one. We repair these roofs and convert them to modern membranes when they reach end of life.
Commercial Metal Roofing
METAL ROOFING SHINGLES
Metal roofing shingles give you the durability of steel with the look of shingles, shake or slate. They are light, shed snow easily and stand up well to wind and hail.
STANDING-SEAM METAL ROOFING PANELS
Standing seam panels run from ridge to eave with raised, concealed-fastener seams. With fewer exposed fasteners there are fewer leak points, and the panels have a long service life on commercial buildings.
STONE-COATED STEEL ROOFING SHINGLES
Stone-coated steel shingles combine a steel core with a granule finish. They resist hail and high winds, and they are much lighter than tile or slate.

Commercial Roofing in Calgary: Frequently Asked Questions
Answers to the questions Calgary property managers and building owners ask us most.
How much does a commercial roof replacement cost in Calgary?
Cost depends on roof size, the system being installed, how many layers need to come off, insulation and drainage work, and access. A small retail unit and a large warehouse can differ by hundreds of thousands of dollars. We provide a written, itemized quote after a site visit so you can compare options side by side.
How long does a commercial flat roof last in Calgary?
Most modern flat roof systems last 20 to 30 years when they are installed correctly and maintained. Hail, poor drainage and skipped maintenance shorten that. Regular inspections and quick repairs are the best way to reach the full service life.
Which flat roof system is best for Calgary weather?
TPO, two-ply SBS and EPDM all perform well here. SBS is tough and handles foot traffic, TPO reflects heat and has welded seams, and EPDM is flexible and cost-effective. The right choice depends on your building, budget and how the roof is used.
Can you work on our roof while the building stays open?
Yes. We plan staging, deliveries and noisy work around your hours, keep entrances clear and close the roof up at the end of every day. Tenants and staff can keep working while the job is under way.
Do you repair hail damage on commercial roofs?
Yes. We inspect the roof, document hail damage with photos and repair punctured membranes, flashings and rooftop equipment curbs. Our reports can be shared with your insurer or adjuster.
How often should a commercial roof be inspected?
We recommend inspections twice a year, in spring and fall, and after any major hail or wind storm. That schedule catches most problems before they cause interior damage.
