• Key Benefits: Extremely durable (often lasting over 30 years), highly resistant to temperature fluctuations, and an excellent option for low-slope or flat roof commercial structures across Shelburne and Mono.
• Targeting Keywords: EPDM is a common material we use for flat roof repair Mono and new commercial installations. Our commercial roofing contractors provide seamless EPDM applications.

Specialized Flat Roof Repair, Leak Detection, and Commercial Maintenance Programs

For property managers in Caledon, Brampton, Mississauga, Shelburne, Mono, Orangeville, and Oakville, the biggest challenge is keeping roofs watertight. Our service division extends roof life through proactive inspections and expert flat-roof repairs.

We believe affordable roofing starts with preventative care. Our maintenance plans stop small issues before they grow into structural damage or force costly premature replacement.

The Critical Need for Proactive Commercial Roof Inspection

Regular, professional roof inspection is the cornerstone of responsible commercial property management. We recommend a comprehensive inspection at least twice per year—ideally in the spring and fall—and immediately following any severe weather event. This proactive approach is the single most effective way to ensure the validity of your manufacturer’s warranty and prevent unexpected downtime.

Our Multi-Point Commercial Roof Inspection Checklist Covers:

• Drainage System Integrity: Checking internal and external drains, gutters, and scuppers for blockages, debris, or damage. Clogged drainage is the leading cause of premature failure in a commercial flat roof.
• Membrane Condition: Detailed inspection for blistering, cracking, shrinkage (especially in EPDM systems), or tears caused by foot traffic or falling debris. We use thermal imaging where necessary to detect trapped moisture or damaged insulation beneath the surface.
• Flashing and Penetrations: Flashing is the roof’s most vulnerable point. We rigorously inspect all seals around HVAC units, vents, pipes, skylights, and parapet walls. Loose or damaged flashing is the source of the majority of all roof leak repair issues.
• Edge Metal and Termination: Ensuring all perimeter edge metal and counter-flashings are securely fastened and sealed to withstand uplift pressures from high winds, common in areas like Oakville and the larger GTA.

We provide a detailed report with photographic evidence, outlining all existing issues and providing actionable, prioritized recommendations for commercial roof repair.

Expert Flat Roof Repair Solutions to Stop Leaks Immediately

A roof leak in a commercial property is not merely a nuisance; it is a threat to inventory, equipment, and structural integrity. Our commercial roofing contractors are specialized in identifying the often-elusive source of the leak, which is rarely directly above the interior stain.

We handle all common and complex issues associated with commercial low-slope and flat roof repair across every one of our service locations:

• Ponding Water Correction: Standing water accelerates membrane deterioration. We provide targeted repair solutions, including addressing structural depressions or improving drainage flow using tapered insulation.
• Membrane Patching and Seam Repair: For punctures, small tears, or split seams, we employ manufacturer-specific patching techniques—heat welding for TPO/PVC and chemical adhesion for EPDM—to create a permanent, watertight seal that restores the roof’s integrity.
• Structural and Thermal Movement Damage: Commercial roofs are subject to constant expansion and contraction. We specialize in elastic sealants and reinforced patching to repair stress cracks and splits caused by thermal cycling.
• Roof Coatings and Restoration: For an aging but structurally sound roof, our fluid-applied roof coating systems (silicone or acrylic) offer a highly affordable roofing alternative to full replacement. These coatings create a seamless, monolithic layer that restores waterproofing, dramatically extends the roof’s life, and can provide significant energy cost savings through high solar reflectivity. This service is highly effective for large commercial properties seeking long-term value.

We offer specialized and immediate flat roof repair services in all our core communities:

Advanced Commercial Roofing Systems: Durability and Performance for Your Business

Choosing the right material is the single most critical decision for any commercial property. Low-slope and flat commercial roofs face tough demands. They must support heavy HVAC units and solar panels, while withstanding Canada’s dramatic temperature shifts. These conditions require advanced materials and expert installation beyond residential standards. United Roofers Inc. is the top choice for Caledon and Brampton businesses. We install and repair all major commercial systems, ensuring longevity and performance tailored to your location.

Single-Ply Membranes: TPO, EPDM, and PVC

Single-ply membranes are lightweight, flexible, and have become the standard for most modern low-slope commercial properties, including those in commercial roofing Caledon and across our service area. Their seamless application and exceptional waterproofing make them an invaluable investment.

• TPO (Thermoplastic Polyolefin) Roofing: TPO is arguably the most popular commercial material today, prized for its energy efficiency and incredible durability. Its naturally white or light-coloured surface makes it a premium ‘Cool Roof’ solution. It reflects UV rays, lowers cooling costs, and reduces the Urban Heat Island effect—a major advantage in hot summers. TPO seams are heat-welded, forming a monolithic chemical bond stronger than the membrane itself. This delivers superior, leak-proof protection, essential for a high-performing roof.
• EPDM (Ethylene Propylene Diene Monomer) Roofing: Often referred to as “rubber roofing,” EPDM is a robust, thermoset membrane known for its exceptional longevity, often boasting lifespans exceeding 30 years. It is incredibly resistant to temperature extremes, hail, and UV exposure. EPDM maintains flexibility in frigid winter temperatures, resisting cracking and shattering, making it an excellent, time-tested choice for Canadian climates. Available in black (for better heat absorption in winter) or white (for a cool roof), its installation requires a deep understanding of adhesive application and flashing details to ensure a long-lasting, watertight seal.
• PVC (Polyvinyl Chloride) Roofing: PVC is the premium single-ply choice for industrial applications, restaurants, and chemical processing facilities. It is uniquely resistant to chemical exposure, grease, oil, and fire. Like TPO, PVC seams are hot-air welded for superior strength. While often the highest initial cost of the single-ply systems, its remarkable resilience and longevity in the most demanding commercial environments make it an investment that pays for itself, providing the ultimate long-term protection for your business.

Modified Bitumen (Mod-Bit) & Built-Up Roofing (BUR)

Modified Bitumen is the next generation of flat roofing. It combines the proven multi-layer waterproofing of traditional Built-Up Roofing (BUR or “tar and gravel”) with the flexibility and strength of modern polymer-modified asphalt.

• Mod-Bit Systems: Mod-Bit comes in rolls installed in multiple plies (layers). This provides exceptional durability and redundancy against leaks. The core of Mod-Bit’s performance lies in its modifiers. SBS (Styrene-Butadiene-Styrene) adds a rubber-like elasticity. This allows the roof to expand and contract dramatically with temperature changes without cracking, which is non-negotiable for the Canadian environment. APP (Atactic Polypropylene) provides a rigid, plastic-like resistance to UV rays.
• Installation methods include torch-applied, cold-applied adhesives, or self-adhering membranes. For torch-applied methods, we ensure a full, consistent fusion to the substrate by a highly experienced professional. United Roofers Inc. employs only the most certified technicians for torch-down applications. This guarantees safety and a perfect, long-lasting membrane fusion.

The Power of Commercial Metal Roofing Systems

While single-ply membranes are ideal for low-slope roofs, commercial properties with a pitch (even a slight one) gain maximum benefit from a commercial-grade metal roofing system. We are expert metal roofing Caledon and Ontario-wide specialists, offering solutions that redefine long-term value.

• Standing Seam Metal Roofing: This is the gold standard for commercial pitched roofs. Featuring panels that connect with a raised, interlocking seam, it offers unparalleled strength and weather resistance.
  • Unmatched Lifespan: Commercial metal roofs often last 40 to 70 years, drastically outlasting all other systems and providing the lowest lifecycle cost.
  • Extreme Weather Performance: The interlocked panels offer exceptional wind uplift resistance and shed snow and ice effortlessly—critical features for properties in the GTA region.
  • Energy Savings: Many commercial metal systems are factory-finished with highly reflective coatings that reduce solar heat gain, contributing to energy savings and eligibility for “Cool Roof” incentives.

Specialized Commercial Services for Ontario Businesses

Beyond general installation, United Roofers Inc. provides specialized services. These are tailored to the economic and environmental needs of businesses in Ontario’s demanding climate.

Cool Roofing and Energy Efficiency Solutions

The commitment to energy efficiency is not just an environmental one; it’s a financial one. Our best roofing company Caledon clients look to us to help reduce their operational costs. White and light-colored TPO, PVC, and cool-coated metal systems are central to this strategy. By installing a high-reflectivity membrane over top-rated insulation, we create a thermal barrier. This reduces the demand on your HVAC systems. The approach also helps you meet—and often exceed—the strict energy performance requirements of the Ontario Building Code (OBC).

Customized Roof Maintenance Programs

Even the most durable roof system will fail prematurely without proactive care. Our customized Roof Inspection & Maintenance plans are designed to maximize the lifespan of your commercial asset. We offer bi-annual inspections (spring and fall) to check for:

• Seam integrity on TPO and Mod-Bit systems.
• Ponding water that can accelerate membrane deterioration.
• Damage around roof penetrations (HVAC curbs, vents, skylights).
• Gutter and drainage system blockages.

This preventative approach ensures minor repairs are addressed before they become costly emergencies, protecting your critical business operations in every weather event. This is why United Roofers Inc. is continuously rated as the best roofing company Caledon for ongoing asset management.
