What Is Considered Flat Roofing?

Flat roofing refers to roof systems that have little to no slope, typically between 0.25/12 to 2/12 pitch. While they appear level, flat roofs are engineered with a slight incline to allow for drainage. Unlike sloped roofing systems, flat roofs require specialized materials and installation techniques to ensure long-term durability and water resistance.

Flat roofs are commonly found on commercial buildings, industrial facilities, condos, townhouses, and modern residential homes in Toronto. Because they’re more accessible and often double as usable space (for HVAC units, patios, or green roofs), proper design and waterproofing are critical.

At TR Flat Roof, we specialize in installing, maintaining, and repairing a wide variety of flat roofing systems—each tailored to meet the unique climate demands of Toronto and surrounding GTA neighborhoods.

Types of Flat Roofing Systems

There are several types of flat roofing systems, each designed for specific needs, budgets, and durability expectations. The most common flat roofing types used in Toronto include:

2-Ply Modified Bitumen (Mod-Bit)
4-Ply Built-Up Roof (BUR)
TPO (Thermoplastic Polyolefin)
PVC (Polyvinyl Chloride)
EPDM (Ethylene Propylene Diene Monomer)

Each of these systems has its own benefits when it comes to lifespan, energy efficiency, weather resistance, and cost. For example, 2-ply and 4-ply roofs are typically asphalt-based and highly durable, while TPO, PVC, and EPDM are synthetic membranes offering lightweight and low-maintenance benefits.

Our team helps property owners across Toronto choose the right flat roofing material based on structure type, exposure to weather, and long-term performance goals.

2-Ply & 4-Ply Roofing Systems Explained

2-Ply Roofing:

This is a modified bitumen system that includes a base sheet and a cap sheet, either torch-applied or cold-applied. It’s a popular choice in Toronto because it offers durability, water resistance, and moderate flexibility. It’s ideal for smaller commercial buildings and residential homes needing reliable protection.

4-Ply Roofing (BUR):

Known as a Built-Up Roof, this system uses multiple layers of asphalt and felt, finished with gravel or a reflective cap sheet. It’s extremely robust and ideal for large buildings needing long-term, low-maintenance protection. With its multiple layers, 4-ply roofs provide excellent resistance against foot traffic and harsh Canadian weather.

Both systems are time-tested and commonly used throughout the GTA for their reliability and strength.

TPO, PVC & EPDM Membrane Systems

TPO (Thermoplastic Polyolefin):

TPO is a single-ply white membrane known for its energy efficiency. It reflects UV rays and reduces cooling costs—making it ideal for Toronto summers. It’s heat-welded for strong seams and offers moderate durability with low maintenance.

PVC (Polyvinyl Chloride):

PVC is similar to TPO but often stronger. It’s resistant to chemicals, fire, and standing water. Its durability makes it suitable for restaurants or commercial buildings with rooftop equipment. PVC roofs are lightweight and long-lasting, often performing well for 20+ years.

EPDM (Ethylene Propylene Diene Monomer):

EPDM is a rubber roofing membrane, black in color, and highly elastic. It’s perfect for large roofs and extreme weather resistance. EPDM is easy to install and cost-effective for flat or low-slope roofs throughout Toronto.

Our experts install all three membrane types, depending on your needs and budget.
