How Long Can I Expect My Roof to Last?

It’s important to know and understand the predicted lifespan for your roof. Nothing is built to last forever, no matter how high in quality and workmanship it may be, and your roof is no exception to this rule. Professional roofing services in London Ontario can advise you on when you need a new roof, but once that brand new roof has been installed, how long can you expect it to last?

The roof is one of the most expensive components of a home. The longevity of your roof will, to a large extent, depend upon its quality, how well it is maintained, and where you live. Environmental issues like snow, ice, wind, hail, strong sunshine, and sea salt can all impact your home and your rooftop.

According to roofing experts, climate and weather events can limit the lifespan of all types of roofs, however as a general rule:

  • Wood Shake roofs can be expected to last up to thirty years
  • Slate, copper, cedar and tile rooftops are premium and can be expected to last in excess of fifty years
  • Asphalt shingle or composite roofs are more affordable and can last up to an average of twenty years.

All of these are dependent upon climate, installation quality, maintenance, and other factors; some asphalt roofs may last longer, for example, if maintained regularly.

You need to understand that there is much more to your roof than just its shingles! Your roof is an engineering feat of layers that offers protection to your home’s interior. It includes:

  • The deck – the foundation of the roof that provides support to the entire structure
  • Drip edge – guides water off roof
  • Ice and water barrier on the deck
  • Underlay – water-resistant, it protects the deck and keeps it dry regardless of shingles
  • Flashing – installed wherever the roof meets a vertical wall e.g. chimney, skylight
  • Shingles – protect roof, repel water, aesthetic appeal
  • Ventilation – to enable movement of fresh air within the rooftop

The lifespan of your roof will be determined by your shingles, your underlay, the ventilation, and the quality of its installation. Shingle longevity is reflected in its price point; proper ventilation can extend the lifespan of your roof by many years.

Knowing the expected lifespan of your roof, as with any other fixture (or even appliance), allows you to make more informed decisions about whether to repair or replace when the time comes to do one or the other.
