The Science Behind SBS

Overview of SBS Roofing Installation Services

SBS roofing is a proven technology in the construction industry, commonly used on flat and low-slope roofs for its strength and durability. With so many Canadian buildings featuring flat-roof structures, the quality of both product and installation is critical. This system works by integrating multiple layers of membranes — bonded together for a seamless, weather-tight finish.

Membrane composition

The main substances used to make these membranes are fibreglass and modified bitumen — synthetic rubber and asphalt that's both flexible and durable.

Bonding SBS roofs

Our technicians use self-adhered, cold, or heat-based welding mechanisms to install the membrane — picking the right method for each job.

Structure of SBS roofs

Multi-ply construction: a base sheet for strength, the modified bitumen core for rigidity, and a flexible synthetic-rubber finish that holds it all together.

Components

Components of SBS Roofing Systems

SBS roofing comprises multiple components — and each one is necessary for a long-lasting system.

The first is the base sheet, the lowest layer whose job is to provide structural strength. The modified bitumen membrane is the core — it delivers the maximum rigidity and reliability of the assembly. Synthetic rubber creates a reliable, flexible base, and a filler is integrated into the mix to keep the bitumen structure flexible.

Why SBS

Benefits and Advantages

SBS roofing systems are built around flexible synthetic rubber, making them highly reliable, durable, and surprisingly straightforward to install. Material runs roughly 20–40% more than TPO or EPDM alternatives — but in the long run, that premium pays off in lifespan and weather performance.

Flexibility

Synthetic rubber membranes flex with temperature swings without cracking.

Reliability

High-grade materials engineered for long-term performance.

Easy Installation

Proven techniques like hot mopping keep installs efficient.

Long Lifespan

Expect 20–30 years of service with proper installation and care.

Step by step

The SBS Roofing Installation Process

Site Assessment & Preparation

We clean the deck and roof, removing debris and foreign material using organic methods that minimize emissions and pollution before a single membrane touches your roof.

Base Layers & Insulation

A vapor barrier base protects the deck from cold-weather condensation, with peel-and-stick membranes available for waterproofing. We then apply EPS, XPS, or poly-iso rigid insulation — glued or mechanically fastened.

SBS Membrane Application

Using torch-down, heat-welding, or cold treatment, we apply the SBS membrane with extra attention to the critical detail areas where the roof meets walls, plumbing, and drains — following manufacturer specs and roofing industry best practices.

Finishing Touches & Quality Control

We test for leaks, flexibility, and durability so your roof is ready for sun, ice, and everything in between. The ideal roof has to withstand extremes — and we verify it can.

Built to last

Warranties and Guarantees

Most manufacturers provide warranties of between 10 and 30 years, covering defects and issues during that period. Because we value our customers, we add a 10-year labour warranty on top of the manufacturer's coverage — and any installation-fault issues that come up are addressed at our cost.

Post-Installation Support

After installation we run post-assessment and tests to verify the roof meets your needs. We carry out testing immediately after install to catch any potential weaknesses, and stress testing is performed to confirm the roof can handle extreme conditions — a must for Canadian weather. We stay engaged with clients to provide the support that keeps your roofing safe and reliable.

Maintenance and Repair Services

Regular Inspections

Regular maintenance is critical to the longevity of your roof. Our teams perform visual inspections to detect texture changes or cracks, clean off debris and ice buildup, and work with clients to clear overhead branches and gutters that could cause water buildup. We also inspect the sealant to verify your roof is staying watertight — keeping it serving you for as long as it should.

Addressing Common Issues

Common issues include cracking from temperature swings, blisters caused by poor drainage and water management, and degraded insulation. We address these through professional inspections, making corrections within the required timeline and in line with prevailing building codes and standards.

Sustainability

Environmentally Friendly SBS Roofing

Energy Efficiency

Our insulation systems are designed to keep heat from escaping the building envelope and help maintain optimal interior temperatures — minimizing energy use. We also build to adapt to the climatic changes happening in every environment we work in.

Sustainable Materials

Sustainability is a core goal. Our material selections favour environmentally responsible options that minimize harm. While most SBS solutions still rely on petroleum-derived asphalt and bitumen, their long lifespan and minimal environmental footprint over time make them an efficient, sustainable choice.
