TPO Roofing System

Markit Roofing installs commercial TPO roofing systems across Alberta. We deliver heat-welded, energy-efficient flat-roof membranes built to handle harsh prairie winters, summer UV, and demanding business conditions backed by manufacturer warranties and certified installation crews you can trust.

At Markit Roofing, we install professional TPO roofing systems for commercial buildings, warehouses, retail centres, and industrial properties throughout Alberta. TPO is a single-ply thermoplastic polyolefin membrane built with hot-air-welded seams, a reflective white surface, and proven resistance to UV rays, chemicals, and ponding water. It lowers cooling loads in summer and stays flexible during Alberta's deep winter temperature swings.

Our trained crews install, repair, and replace TPO roofs using proven attachment methods, code-compliant detailing, and clean job-site practices. Whether it's new construction, a re-roof, or a full membrane replacement, we deliver dependable commercial protection backed by strong manufacturer warranties.

TPO Roofing System

What is a TPO Roofing System?

A TPO roofing system is a single-ply commercial membrane made from thermoplastic polyolefin, typically supplied in 45-mil, 60-mil, or 80-mil thicknesses. It’s installed on flat and low-slope roofs because it combines strong waterproofing, heat reflection, and excellent material flexibility. Each seam is hot-air welded into a continuous, watertight bond, sealing the roof against leaks, wind-driven rain, and long-term weather wear.

Commercial property owners across Alberta choose TPO because it balances upfront cost with strong long-term performance. The reflective white surface cuts rooftop temperatures and helps lower air-conditioning bills, while welded seams resist the leaks that often plague taped or glued membranes. TPO suits warehouses, retail plazas, office buildings, and industrial facilities where dependable, energy-efficient roofing protects daily operations.

Types of TPO Roofing System

TPO roofing comes in several installation styles, and the right choice depends on building height, deck type, wind-uplift requirements, insulation thickness, and overall project budget. Some systems are mechanically fastened to the deck, others are fully adhered with bonding adhesive, and a few rely on weighted ballast. The correct attachment method directly affects wind resistance, seam integrity, and long-term performance.

Mechanically attached systems are fast to install and work well on large commercial decks. Fully adhered TPO bonds tightly to insulation for a smoother, low-profile finish on visible roofs. Ballasted systems use river rock or pavers to hold the membrane firmly in place. Fleece-backed TPO adds puncture resistance, and induction-welded systems combine secured plates with hidden fasteners for clean aesthetics.

Our Process

Roof Inspection and Planning

Every project starts with a full commercial roof inspection. Our team measures roof slope, evaluates drainage patterns, and carefully checks the existing membrane, insulation, flashings, penetrations, edges, parapet walls, and any signs of ponding water or damaged sections. We also review building usage, energy efficiency goals, weather exposure, and your project budget before recommending the most suitable TPO installation method.

This planning stage helps us select the correct TPO thickness, attachment system, and insulation upgrade for your specific building. A detailed inspection prevents costly callbacks, reduces hidden costs, and gives you a clear, written scope of work before installation begins.

Surface Preparation

After the inspection, our crew prepares the roof so the new TPO membrane bonds and welds correctly. Preparation includes removing debris and loose materials, cleaning the substrate, repairing damaged decking, improving drainage slope, securing or replacing insulation boards, and confirming the deck is structurally sound. A clean, stable surface is essential for proper membrane attachment.

Skipping this stage leads to seam failures, lifted edges, and premature leaks. Thorough preparation protects waterproofing, supports stable energy performance, and extends the service life of your commercial roof through Alberta’s freeze-thaw cycles, heavy snow loads, and hot summer temperatures.

TPO Membrane Installation and Review

With the deck ready, we install the TPO membrane using the attachment method selected for your building. Our crew rolls out the sheets, mechanically secures them per spec, hot-air welds every seam, reinforces the edges, and carefully details all roof penetrations.
 

Every weld is probe-tested to confirm a watertight bond, and flashings are fully sealed at curbs, drains, and HVAC penetrations. Once installation is complete, we walk the roof with you, hand over warranty paperwork, and provide a simple maintenance schedule so your new TPO system performs as expected for decades.

Frequently Asked Questions

With its UV resistance and strong construction, a TPO roof installed and in proper condition can withstand up to 25-30 years or longer.

Yes, it has a very reflective white surface, which means that it absorbs less heat, which minimizes cooling expenses and in most localities is eligible to receive energy rebates.

Frequently so, as a retrofit or overlay, when the existing structure is in good condition- time and cost saved versus complete tear-off.

TPO is also comparable to EPDM in terms of durability but has enhanced heat welded seam and reflectivity, it is usually cheaper than PVC and environmentally friendly.

It is true; it does not get moldy, does not take in chemicals and does not get punctured; it only needs some regular checkups and cleaning to ensure that it performs optimally.
