Why replace a commercial roof?

The roof is a key component of a building, as it protects the interior from the elements, such as rain and snow, as well as from animals. Its presence is also essential to ensure thermal insulation within the building, and thus to maintain a more or less comfortable temperature throughout the year. It is essential that it is in good condition to perform all these functions, which is why replacement is necessary in the following cases:

The roof has aged

Under the best conditions, and if properly maintained, a roof can last up to 30 years. After this time, it begins to weaken, even if there are no visual signs.

We recommend that you seriously consider replacing the roof of a commercial building as it begins to age, to avoid facing serious problems such as water infiltration or even collapse later on. Repairing the damage caused by these problems can be very costly.

The roof is starting to show signs of ageing

Quebec’s particularly capricious climate generally leads to premature aging of the roof. So it’s important to have it professionally inspected at least once or twice a year to detect any damage or signs of ageing. He will then guide you towards the most appropriate solution, including replacement if necessary.

You notice anomalies and reduced comfort within the building

Finally, it might be time to think about replacing the roof of a building if you notice the following anomalies:

  • The roof begins to sag;
  • Mould and fungus appear on the shingles;
  • The roof is leaking and water infiltration problems are becoming noticeable;
  • The roof lets in outside light;
  • You feel the cold or heat more than usual, which is a sign of a lack of insulation;
  • Eaves troughs, shingles and fastening nails have all come loose.

In all cases, it’s essential to call in a professional who will carry out a thorough inspection of the roof before starting any work.
