The signs of wear and tear on your roof

A Canadian roof lasts an average of 15 to 20 years. However, this varies largely depending on the quality of the roof itself. In case of rapid deterioration, it is of paramount importance to replace this essential structure of your home. Here are some tips to learn to recognise the wear and tear signs and to know whether you should only maintain or completely replace your roof.

Cracks and Leaks

Cracks and leaks will naturally appear on your roof after some years. Due to climate hazards which may worsen the state of your roof, it is strongly recommended to check for cracks and leaks in your roof. To better identify them, you should inspect your roof once or twice a year, especially if you want to keep it optimal for as long as possible. Once the paint begins to peel off, watch for leaks. Water infiltration can be also caused by the deterioration of the shingles. Although the damage may be minimal, it is better to hire a roofer to help you restore the torn elements.


Mold is yet another sign of wear on your roof. Over time, the dirt that accumulates on the roof will contain a significant number of fungi. This fungi can be lodged in every corner of the shingles and consequently tarnish the structure with dark vertical lines. Asphalt roofs are mostly affected by mold. The fungi feed on the limestone constituting the roof, thus accelerating its deterioration. Take advice from a professional and take regular care of this kind of roof to prevent the apparition of fungi. That said, as time promotes their development, the need to replace the roof can impose itself.

Water Stains on Your Ceiling

Once signs of moisture appear, including water stains on the ceiling, change your roof as soon as possible. This moisture comes from leaks in the roof, often caused by the deterioration of the roof. At this point, the repair will only temporarily mitigate the damage.
