Your roof is perhaps the most critical part of your house. It covers and protects you and your loved ones from extreme weather conditions all the time. 

However, your roof’s efficiency depreciates over time. After some time you may begin to experience roof leaks and other problems associated with an old roof. 

While the cost of replacing a roof might be a little bit higher, the cost of waiting for too long is much higher. 

Therefore, it pays to know when it is time to replace your roof. Here are the top five telltale signs that it is time to replace your roof. 

• Roof Age

While most roofing materials can last for up to 30 years, most roofs tend to hit their limit after 20 to 25 years. This is particularly true if you stay in a region that experiences extreme weather conditions quite frequently. 

Also, if your roof was installed over an old layer of shingles, then its lifespan reduces significantly. 

Furthermore, if your current roof was laid over old shingles and it is more than 20 years old, then it is time to replace it. With proper maintenance, single-layer roofing can last for up to 25 years. 

However, the moment you hit the 25-year mark, you will need to start thinking about replacement.

• Peeling or Curling Shingles

Asphalt shingles usually have a definite lifespan, and once they approach the end of it, they start showing numerous signs of wear. 

If you notice that some of your shingles are peeling, then it is a sign that they have started to break down. Also, if your shingles begin to curl at the corners, then it is time to call in roof replacement Montreal experts to replace the roof. 

Ignoring peeling and curling shingles for too long can be catastrophic.

• Roof Leaks

Rainwater finding its way into your house is another good sign that your roof is leaking and requires replacement. Checking your attics regularly, especially after a heavy rainstorm is an excellent way to monitor existing leaks. 

If you notice water stains on your ceiling, then there is a good chance your roof is leaky. Growth of mold and paint that is bubbling/cracking are other good signs to watch out for.

• Sagging Roof

A sagging roof should always be a cause of major concern. Typically, a sagging roof may be a sign of a structural issue that needs an urgent solution. In other cases, a sagging roof can occur as a result of water damage. 

While a sagging roof may not be an indicator of imminent danger, it is always good to address the issue before it progresses into something significant. 

To check for a sagging roof, simply observe the roofline and see if there is any noticeable dip, curve, or swag present.

• Loose Granules

Most asphalt shingles are constructed with granules on the surface that helps to direct rainwater off the roof. However, once your shingles start to age, the granules begin to loosen and fall off. 

The moment you start noticing small pebble-like granules building up on your eaves, it could be a sign of a problem. 

Once your roof shingles start to shed the granules, it means that they are aging and may no longer offer the protection you and your loved ones need.
