If you manage or own a commercial property in Pickering, Ajax, or anywhere in Durham Region, the condition of your roof directly affects your bottom line. A leaking flat roof means damaged inventory, disrupted tenants, and repair costs that climb the longer you wait. Choosing the right commercial roofing contractor is not something you want to rush, but it is something you need to get right the first time.
At Metro Roofing, we have been handling commercial roofing projects across Pickering and Durham Region for over 40 years. From flat roof repairs on strip plazas along Kingston Road to full membrane replacements on industrial buildings near Highway 401, we have seen every type of commercial roof issue this area produces.
Why Commercial Roofs in Pickering and Durham Region Take a Beating
Durham Region’s climate is hard on commercial roofs. The combination of Ontario’s freeze-thaw cycles, heavy snow loads in January and February, and summer heat creates a repeating pattern of expansion and contraction that breaks down roofing materials over time.
Commercial properties along the Westney Road and Kingston Road corridors in Ajax and Pickering are especially vulnerable. Many of these buildings were constructed in the 1980s and 1990s with flat roof systems that are now approaching or past their expected lifespan of 20 to 25 years.
Here is what we see most often on commercial roofs in this area:
- Ponding water from clogged drains or inadequate slope
- Flashing failures around HVAC units, skylights, and parapet walls
- Membrane splitting caused by repeated freeze-thaw expansion
- Ice damming along roof edges during late winter and early spring
- Blow-offs where wind lifts membrane sections that were not properly adhered
Commercial Roofing Systems We Install and Repair
Not every commercial roof is the same. The right system depends on your building’s structure, your budget, and how long you plan to own or manage the property.
| Roofing System | Best For | Typical Lifespan | Cost (per sq ft) |
|---|---|---|---|
| TPO Membrane | Budget-conscious flat roofs | 15-25 years | $8-$12 |
| EPDM Rubber | Large flat commercial roofs | 20-30 years | $7-$11 |
| Modified Bitumen | Multi-layer flat roofs | 15-20 years | $6-$10 |
| Metal Roofing | Industrial, sloped commercial | 30-50 years | $12-$20 |
| Built-Up Roofing (BUR) | Heavy-duty flat roofs | 20-30 years | $8-$14 |
For most commercial flat roofs in Pickering, we recommend TPO or EPDM. For properties that need extra durability, commercial metal roofing may be the better option.
Signs Your Commercial Roof Needs Attention
Commercial roof problems rarely announce themselves with a dramatic leak. More often, the signs are subtle.
Schedule a roof inspection if you notice:
- Water stains on ceiling tiles or interior walls
- A sudden increase in heating or cooling costs
- Visible bubbling, cracking, or blistering on the roof surface
- Pooling water that remains 48 hours after rainfall
- Musty smells in the building, especially on upper floors
- Sagging in any section of the roof deck
Commercial Roof Repair vs. Replacement
Repair makes sense when:
- Damage is localized to one section (less than 25% of the roof area)
- The membrane still has useful life remaining
- The issue is a specific failure point (flashing, drain, penetration seal)
- Your roof is under 15 years old
Replacement makes sense when:
- You are patching the same roof every season
- Damage covers more than 25% of the roof surface
- The underlying decking shows signs of rot or structural compromise
- The roof is past its expected lifespan
