Locally owned and operated for 40+ years
Here's what matters with commercial flat roof installation in Ajax. Your roof isn't just protecting a building - it's protecting your business operations, your employees' work environment, your inventory, and your equipment. A poorly installed commercial flat roof leads to leaks that damage products, disrupt productivity, and cost you money in repairs and lost business.
Roofing System | Best For | Key Benefits | Typical Lifespan |
TPO | Energy efficiency, large buildings | UV resistant, heat-welded seams, reflects heat | 20-30 years |
EPDM | Extreme weather resistance | Flexible, handles freeze-thaw cycles, low maintenance | 20-25 years |
Modified Bitumen | High foot traffic, rooftop equipment | Flexible, excellent waterproofing, easy repairs | 15-20 years |
We’ve installed commercial flat roofs across Ajax and the GTA for over 35 years, from small office buildings to large industrial warehouses. The biggest concern we hear from property managers and business owners? Downtime. You can’t afford to close your business for weeks while a roofing contractor works overhead. That’s why our commercial flat roof installation process focuses on minimal disruption while delivering durable, leak-proof systems built to last decades.
At Metro Roofing, we understand commercial properties have different needs than homes. We’ve installed flat roof systems on office buildings throughout Durham Region, warehouses in Ajax’s industrial areas, retail properties, and commercial facilities of all types. Our certified crews know how to work efficiently around your business schedule, whether that means weekend installation, off-hours work, or phased projects that keep parts of your building running.
We install TPO, EPDM, and Modified Bitumen systems with full warranties on both materials and labor. Your commercial flat roof installation gets the quality workmanship and durable materials your business investment deserves.
EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber membrane known for flexibility and long-lasting performance. We install EPDM systems that resist extreme weather, provide excellent waterproofing, and require minimal maintenance over their lifespan.
EPDM works exceptionally well for Ajax commercial properties because it handles freeze-thaw cycles without cracking, resists heat and ozone damage, and provides electrical insulation. Whether torch-applied or mechanically fastened, our EPDM installations deliver decades of reliable protection.
Modified Bitumen offers exceptional waterproofing with reinforced strength and durability. This asphalt-based roofing membrane expands and contracts to fit your commercial building's roofing system, making it ideal for buildings with equipment, HVAC units, or high foot traffic on the roof.
We install Modified Bitumen using torch application or cold adhesive methods, depending on your building's needs and local fire codes. The result is a flexible, weather-resistant roof that's easy to maintain and repair if needed.
Not every commercial building in Ajax fits a standard solution. We design custom flat roof systems tailored to your specific property requirements, budget, and operational needs. Whether you're dealing with unusual roof dimensions, specific drainage challenges, or buildings with rooftop equipment, we create installations that work for your business.
TPO (Thermoplastic Polyolefin) is one of the most popular commercial flat roofing systems, and for good reason. We install TPO membranes that are energy efficient, highly durable, and resistant to punctures and UV damage. The white reflective surface helps reduce cooling costs for your Ajax commercial property, which matters during hot summer months. Our TPO installations use heat-welded seams that create a watertight bond stronger than the membrane itself. This means leak-proof protection that holds up to pooling water, temperature extremes, and the harsh weather Durham Region commercial buildings face.

Flat roof installation typically costs between $4 and $13 per square foot, depending on the material and project complexity.
The total expense varies significantly based on your material selection, roof size, and regional labor rates. Basic built-up roofing systems represent the lower end of the pricing spectrum, while premium options like modified bitumen or TPO membrane systems command higher rates. Understanding the complete breakdown of flat roof installation pricing helps property owners budget accurately and select the most cost-effective solution for their commercial building.
TPO (thermoplastic polyolefin) membrane is the most popular material choice for commercial flat roofs due to its durability and energy efficiency.
This white reflective material excels in reducing cooling costs while providing excellent resistance to UV rays, tears, and punctures. While EPDM rubber and PVC membranes also remain viable options, TPO has gained market dominance because it balances performance with affordability. For a comprehensive analysis of how different commercial roofing materials compare in terms of longevity, maintenance requirements, and total cost of ownership, property managers should review detailed material specifications before finalizing their selection.
Commercial flat roofs typically last between 10 and 50 years, depending on the material and maintenance quality.
Built-up roofing systems generally provide 15-20 years of service, while EPDM rubber roofs can reach 20-25 years with proper care. Premium materials like PVC and TPO membranes often exceed 30 years when professionally installed and maintained. The actual lifespan depends heavily on climate conditions, installation quality, and regular inspections. Learning about the factors that affect commercial flat roof longevity can help building owners maximize their investment and plan replacement timelines effectively.
Built-up roofing (BUR) systems are the most budget-friendly option, costing $4-7 per square foot installed.
These traditional tar-and-gravel roofs deliver reliable performance at the lowest price point, making them ideal for cost-conscious commercial property owners. While BUR systems require more maintenance than modern single-ply membranes, their proven track record and straightforward repairs keep long-term ownership costs manageable. EPDM rubber roofing represents another economical choice at $5-8 per square foot. For property owners seeking affordable flat roofing options without sacrificing quality, exploring various budget-friendly materials and their performance trade-offs provides essential decision-making guidance.
Flat roof costs are calculated by multiplying the roof’s square footage by the per-square-foot material and labor rate, then adding overhead expenses.
Start by measuring your roof’s total area, including parapets and penetrations. Material costs typically range from $1.50-$6 per square foot, while labor adds another $2.50-$7. Factor in removal of existing roofing ($1-3 per square foot), substrate repairs, and disposal fees. Your final estimate should include contingencies for unexpected damage discovered during tear-off. A comprehensive guide to estimating flat roof replacement costs breaks down each expense category and helps identify potential hidden costs before starting your project.
