The age of your roof is a good indicator of whether it’s time for a roof replacement. Whether you’re in the market for a new home or intend to stay in your present one, you’re definitely aware of the state of your roof. However, it can be difficult for homeowners to determine when it is time to repair their roofs.  Our Roofing Contractor Halifax team has broken down the five main types of roofs (roofing products), what can affect the longevity of the roof, how long each type of roof lasts, and what indications to watch for when your roof might need to be replaced.

What factors impact how long your roof lasts?

Looking to get a better idea of what factors could impact the life span of your residential roof? This list will give you much more insight.


This should go without saying, but the older the average roof is, the more likely you will be looking at the need for roof repair or replacement. While you may be smitten by that remodeled historical home with the low asking price, do yourself a favor and inquire about roof inspections before making a purchase.

If you suspect your roof is nearing the end of its useful life, contact your roofing provider to see what may be done to safely extend its life. Even if you have a new home with a brand spanking new roof, don’t ignore it over time, or you may find yourself having to hire roofing professionals to replace it much sooner than you anticipated. 

Materials Used

The average lifespan of various roofing materials varies. Asphalt shingles will last 15 to 18 years with normal roof maintenance. Laminate roof shingles do a little better, lasting an average of 24 to 30 years.
Wood cedar shingles and as well as metal last a long time (30 to 40 years – 30 to 45 years), although clay-slate tiles can last up to 50 years when put in place by a roofing professional.  


Everyone often speaks about how Canada can get really cold in the winter, but we rarely speak about how hot it can get in during the summer months. Dark roofs are particularly susceptible to collecting too much heat, resulting in cracking and melting, as well as other issues connected with a vulnerable roof component.


A roof’s deadliest enemy is humidity. Don’t be shocked if your roof’s average lifespan doesn’t meet the expectations of what’s listed in the official description in locations prone to heavy precipitation, such as hail, sleet, and snow. Winter may be very destructive, especially when temperatures swing between above zero and freezing. Ice dams can form as a result of freeze-thaw cycles, causing a slew of roof-related issues. 

Poor ventilation

A roof is more than just the quality of the shingles or anything. Proper ventilation is critical for preventing ice dams on the roof throughout the winter because it keeps air moving and your roof cool. In the summer, ventilation keeps your roof from becoming too hot, eliminating the need to lower the thermostat.

How long do asphalt shingles last exactly? Because they’re economical (averaging $70 – $150 per square foot) and come with guarantees of up to 25 years, the most prevalent type of roofing material marketed today is asphalt shingles. They give a permanent layer of protection against UV rays, heavy rain, and wind, and are made up of a variety of substances such as organic materials and cement fibers. A layer of black asphalt on the bottom of the shingles gets sticky in the heat of the sun and seals everything in place, forming a watertight seal (helps prevent roof leaks).
