From freeze-thaw cycles that stress membrane systems to heavy snow loads that test structural integrity, understanding your roofing options is critical to protecting your investment.
Below we answer common questions about commercial roofing systems, maintenance requirements, and what Milton business owners should expect when working with professional roofing contractors.
How often should I schedule commercial roof inspections?
We recommend professional roof inspections twice annually—once in spring after winter damage assessment and again in fall before harsh weather arrives. Ontario winters are particularly hard on commercial roofing systems, with ice damming, snow accumulation, and temperature swings causing deterioration you won't spot from ground level.
Regular inspections catch small issues before they become expensive emergencies. Ponding water, membrane splits, and flashing failures are easier and cheaper to address when detected early.
What's the difference between TPO and EPDM roofing?
Both TPO and EPDM are popular single-ply membrane systems for flat commercial roofs, but they have distinct characteristics:
- TPO (Thermoplastic Polyolefin): White or light-colored surface reflects UV rays and reduces cooling costs. Heat-welded seams create watertight bonds. Popular for energy efficiency.
- EPDM (Ethylene Propylene Diene Monomer): Black rubber membrane with excellent durability and weather resistance. More affordable upfront. Seams are typically adhesive-bonded or taped.
Both systems perform well in Milton's climate when properly installed. Your choice often depends on building use, budget, and energy efficiency goals.
Do I need a building permit for commercial roof work in Milton?
Most commercial roof replacement and significant repair projects require building permits from the Town of Milton. Permit requirements ensure work complies with Ontario Building Code standards for structural load, fire rating, insulation values, and drainage.
Licensed commercial roofing contractors typically handle permit applications as part of the project scope. Permit review times vary, so factor this into your project timeline. Minor repairs and maintenance work may not require permits, but always verify before starting work.
How long do commercial roofing systems last?
Lifespan depends on the roofing system, installation quality, and maintenance:
- TPO and EPDM membranes: 15-25 years with proper maintenance
- Modified bitumen: 15-20 years
- Metal roofing: 30-50 years depending on coating and fastener systems
- Built-up roofing (BUR): 20-30 years
Regular commercial roof maintenance extends these lifespans significantly. Neglected roofs often fail prematurely due to ponding water, clogged drains, or unrepaired punctures.
What should I do if my commercial roof is leaking?
Roof leaks require immediate attention to prevent interior damage, inventory loss, and business disruption. First, contain the leak with buckets and tarps if safe to do so. Document the damage with photos for insurance purposes.
Contact a commercial roofing contractor for emergency roof repair service. Many Milton contractors offer 24/7 emergency response to minimize downtime and protect your property. Temporary repairs stabilize the situation while permanent roof repair solutions are planned.
Can I install a new roof over my existing commercial roof?
Roof-over installations (also called overlays or recover systems) are sometimes possible and can reduce costs by eliminating tear-off and disposal expenses. However, this approach isn't always appropriate.
Building codes typically limit the number of roof layers. The existing roof deck must be structurally sound, dry, and free from extensive damage. If the current system has moisture trapped in insulation layers or significant deterioration, a complete tear-off is necessary.
A thorough inspection determines whether overlay is viable or if complete roof replacement is the better investment.
