How long will my roof last?

Here are the most common types of roofing products in Canada, and how long they’re likely to last:

Asphalt Shingles

Asphalt shingles are the most common and the most affordable roofing material. They’re also highly effective at being able to withstand most weather conditions. When installed correctly, you can expect asphalt shingles to last between 15 and 20 years.  Be sure to confirm in writing that the installer is meeting all the requirements during the installation or that 20-year warranty maybe void from the start.

Metal Roofing

Metal is one of the most durable roofing systems and is becoming increasingly popular as a material. There are lots of different designs, styles, and colors to choose from, and if it’s well maintained, it can last several decades (40-70 years).  Some installers install Metal roofs directly on top of existing asphalt to save time and money.  We don’t recommend that practice and feel that the roof should be stripped back to the deck for a fresh installation.

Wood Shingles

Wood shingles are a more traditional type of material most often found on the west coast. You can expect wood shingles to last up to 30 years if properly maintained. If properly treated, the wood will be resistant to rot and will prevent insects from inhabiting it.  Wood shingles can be quite expensive due to the labor cost involved in the installation.

Clay Tiles

A  clay tile is one of the oldest and most durable materials available.  Clay tiles can last up to 80-100 years without significant maintenance.  Clay tiles offer a wide selection of styles, shapes, colors, and finishes, perfect for any design style.  Often found in warm climates, Clay tiles can be used in cold climates if correctly engineered.  All of our tiles have been tested and certified for use in the harshest of cold climates.


Concrete Tiles

Concrete tiles, like clay offer superior life expectancy and weather protection over traditional asphalt or metal roofs.  Concrete tiles have a lifespan of 50-75 years, depending on the climate they reside in.  Concrete tiles offer the look of the popular Clay roofing styles at a discounted material price.


Elements that Affect the Lifespan of a Roof

The lifespan of your roofing material, is determined by the following factors:

Installation Quality

Poor workmanship on a roofing installation can take years off the useful life. The lower cost of hiring a less experienced contractor is greatly outweighed by the potential increased repairs and replacement costs further down the line.

That’s why it’s vital to ensure that your roof installation is completed by reputable, experienced roofing companies who can complete the work correctly to a high standard.

Roofing Type

As stated earlier, the specific material used in your roofing has a considerable impact on how long it lasts. Traditional materials like asphalt and wood and tend not to last as long as tile alternatives.


This is the water-resistant layer that sits underneath the roofing material, providing an added layer of protection. If this starts to wear out over time, it could threaten the longevity of the whole structure.


The build-up of moisture in your attic can lead to the build-up of mold and, ultimately to the gradual decay of the internal structure of your roofing. Installing proper ventilation is vital to the performance of your home and your roofing material.
