Flat Roofing Services for Commercial and Industrial Properties


At RJeneration London Roofing & Renovations, we specialise in providing expert flat roofing solutions tailored to commercial and industrial properties across Southwestern Ontario. Our team delivers durable, high-performance flat roofing systems designed to withstand Canada's diverse weather conditions, from heavy snow and ice in winter to intense summer heat and UV exposure. Whether you manage a warehouse, manufacturing facility, office building, retail centre, or industrial complex in London, Windsor, Hamilton, or surrounding areas, we focus on protecting your investment with reliable installations, repairs, and maintenance.

Why Choose Flat Roofing for Commercial and Industrial Buildings?

Flat roofing systems remain a preferred choice for commercial and industrial structures due to their practical design and performance benefits. These low-slope or near-horizontal roofs offer efficient coverage for large surface areas common in factories, distribution centres, and multi-unit commercial properties.

One key advantage lies in cost-effectiveness during installation, as flat roofing requires simpler structural support and fewer materials compared to steeply pitched alternatives. This efficiency makes it ideal for expansive buildings where maximising interior space is essential.

Accessibility stands out as another major benefit. Our team can easily perform inspections, cleaning, and minor repairs on a flat surface without the need for complex scaffolding or safety equipment typically required on sloped roofs. This simplifies ongoing upkeep and helps identify potential issues early, supporting the long-term integrity of your building.

Flat roofing also supports practical space utilisation. Many commercial and industrial owners place HVAC units, ventilation systems, solar panels, or other equipment on the roof, freeing up valuable ground-level space for operations or storage. In energy-conscious projects, reflective membrane options help reduce cooling demands by deflecting sunlight, contributing to more comfortable indoor environments year-round.

Durability plays a central role in flat roofing performance. Modern materials resist UV radiation, ponding water (with proper drainage), and temperature fluctuations common in Ontario. When installed correctly, these systems provide reliable protection against leaks, wind uplift, and environmental wear, helping safeguard your assets, inventory, and occupants.

Common Types of Flat Roofing Systems We Install

Our experience covers a range of proven flat roofing options suited to commercial and industrial applications:


  • Built-Up Roofing (BUR): This traditional multi-layer system uses alternating plies of reinforcement fabrics and bitumen, topped with gravel or aggregate for added protection. It delivers excellent waterproofing and impact resistance, making it suitable for high-traffic or heavy-duty industrial settings.
  • Modified Bitumen: Enhanced with polymers for greater flexibility and strength, modified bitumen membranes come in torch-applied or self-adhered forms. These offer superior performance in cold climates and resist cracking or splitting over time.
  • EPDM (Ethylene Propylene Diene Monomer): A synthetic rubber membrane known for its exceptional elasticity and UV resistance. EPDM performs reliably in extreme temperatures and requires minimal maintenance, ideal for large commercial rooftops.
  • TPO (Thermoplastic Polyolefin) and PVC: These single-ply thermoplastic membranes feature heat-welded seams for strong, leak-resistant coverage. Their reflective white surfaces promote energy efficiency, and they resist chemicals, grease, and punctures—perfect for restaurants, warehouses, and manufacturing facilities.


We select the most appropriate system based on your building's specific needs, structural requirements, and local environmental factors in areas like London and Windsor.

The Importance of Professional Installation and Maintenance

Proper installation forms the foundation of any successful flat roofing project. Our skilled technicians ensure precise drainage slopes, secure seam sealing, and integration with existing building components to prevent common issues like ponding water or membrane failure. We adhere to industry standards and manufacturer guidelines to maximise system longevity.


Regular maintenance extends the life of your flat roof significantly. Routine inspections help detect debris buildup, membrane wear, flashing issues, or drainage problems before they escalate. In Ontario's climate, where freeze-thaw cycles and heavy precipitation occur, proactive care prevents costly damage and maintains warranty coverage.


Our team provides comprehensive services, including full inspections, targeted repairs, membrane recoating, and complete re-roofing when needed. We handle everything from minor leaks to large-scale restorations for commercial and industrial clients.
