Asphalt shingles are among the most commonly used roofing materials in homes across Canada. They are affordable, durable, and come in a variety of styles and colors. However, like any other component of your home, they have a lifespan and will eventually need to be replaced. In this blog post, we’ll discuss the key indicators that your asphalt shingles may be nearing the end of their life and when you should consider replacing them.
What Are Asphalt Shingles?
Asphalt shingles are made of a fiberglass or organic mat coated with asphalt and topped with granules that protect from UV rays. They are known for their versatility, cost-effectiveness, and ease of installation. Asphalt shingles typically last between 15 to 30 years, depending on the quality and maintenance.
Signs of Aging and Damage
Curling or Cupping Edges
When the corners of the shingles start to curl up or the shingle itself looks like a cup, this could be an indication that they are reaching the end of their life. This often occurs due to long-term exposure to the elements.
Loss of Granules
As shingles age, they begin to lose the protective granule layer, making them more susceptible to damage. If you find granules in your gutters or notice bald patches on the shingles, it may be time for a replacement.
Cracks or Tears
Cracks in shingles can occur due to extreme weather conditions like wind or hail. These fissures can lead to leaks and other roofing issues if not addressed promptly.
Moss or Algae Growth
While not a definitive sign of aging, the presence of moss or algae can indicate moisture retention, which is not good for the shingles in the long term.
Sagging or Uneven Areas
A sagging roof is a serious issue and often points to problems with the roofing structure. If you notice this, immediate inspection and likely replacement are needed.
When Should You Replace Asphalt Shingles?
- Age: If your roof is close to or past its expected lifespan, proactive replacement is advisable.
- Multiple Issues: If you observe more than one of the signs listed above, it’s likely time for a new roof.
- Major Damage: After a severe storm or other significant event, immediate replacement might be necessary to prevent further issues.
