How Often You Should Replace the Roofing on Your House

You’re roofing is important. It protects your home from the elements and makes sure that no rain, animals or foreign debris make their way inside.

At Delrei Roofing, Exteriors & Restoration, we offer services that range from installation, to maintenance and even complete re-roofing. Let us show you just how easy it can be to figure out if your home is in need of a new roof and how often you should have it done.

What to look out for

Before we get into how often you should have your roofing redone by an expert in Lethbridge, let's take a look at the different factors you should look out for when deciding to re-roof your home. Here are a few flaws that generally dictate when it’s time for some repairs: 

  • Your roof looks old and worn: age is a sure sign that it might be time to change your roof.
  • Cracked shingles: damage is one of the top signs that your roof needs to be redone.
  • Streaks: these are caused by airborne algae. While it doesn’t harm the structural integrity of your roof, it certainly doesn’t look good. You might not have to replace the whole thing, but streaks surely mean some maintenance is in order.
  • The appearance of moss: moss holds moisture. During the cold months of winter in Canada, this will cause it to freeze and possibly cause structural damage to your roof. 

The average lifespan of different materials

While the factors above determine when it might be time to replace your roof, there’s also a finite number of years that can go by before it becomes time to re-roof your home. When it comes down to it, there’s no one answer for how long a roof should last. Let us tell you when it’s time to replace your roof based on the type of material you had installed.

  • Asphalt shingles: the lifespan of this popular and aesthetically pleasing material should be right around 20 years on any Lethbridge home. This is only an average; some shingles of higher quality could last up to 25 and in some cases, even 30 years. 
  • Metal shingles: Being one of the higher quality and more expensive roofing options, these generally last up to 50 years before they need to be replaced. 
  • Clay tiles: while these are more rare than other materials, clay tiles can last anywhere from 30-50 years depending on weather conditions in your hometown.
