Looking to fix or replace your flat roof?

For Canadian homeowners—whether you own a mid-century bungalow, a modern detached home, or an urban multiplex—replacing a flat roof is one of the most important investments you can make to protect your property long term. With increasingly unpredictable winters and frequent freeze-thaw cycles across many regions of Canada, the question is no longer just whether your roof leaks, but how to optimize waterproofing while meeting updated 2026 energy efficiency standards.

In 2026, the cost to replace the roof of a standard single-family home in Canada generally ranges from $10,000 to $18,000 for asphalt shingles. For a metal roof, the budget typically falls between $25,000 and $50,000, depending on the surface area, slope, accessibility, and complexity of the project. These estimates typically cover the removal of the old roofing, debris disposal, new materials, and labour by a qualified contractor holding the appropriate provincial licences—ensuring your roof can withstand Canada’s demanding climate.

TPO and EPDM roofing membranes are used to cover flat rooftops. These roof covering materials are very durable and have grown in popularity in the past few years in Canada. If you want to learn more about TPO and EPDM roofing, RenoQuotes.com has prepared a global overview of these materials:
