Should I Repair or Replace My Roof?

Tips from Ottawa’s Trusted Roofing Company

The roof of your home or business works in tandem with the foundation and walls of the building. It is the first to receive the UV rays and pounding rains while it protects the people and contents inside. When it is in good shape, everything and everyone stays dry, warm or cool, and happy. Once damage occurs, however, water can leak into the walls leading the way for mold to grow.

Knowing when to repair versus when to replace a roof depends on many factors. A specialist from Sanderson Roofing knows the difference and which option makes sense for your situation. Whether it is made up of asphalt shingles or is a flat commercial one, our experienced team is ready to help ensure your investment is protected.



Ascertaining the condition of your roof is critical to deciding whether to repair or replace the system. In general, look for the following signs of damage:

  • Discoloured shingles

  • Asphalt granules collecting in the gutters

  • Missing, cracked, torn, curling, or bald shingles

  • Age of the roof

  • Sunken/sagging areas of decking

  • Blistering membranes

  • Large rips or tears in rubber membranes

  • Small holes or punctures

  • Water leaks in the interior of your house or business 


You can extend the life of your roof when you consider these reasons to make the needed repairs of your residential shingle or commercial flat roof:

  • There are only a few shingles missing in a small area.

  • The roof is relatively new; that is, it has not reached the end of life of the materials.

  • If you know the reason for the damage and it is isolated, such as from a storm.


It is not always possible to make a few repairs to extend the life of your roof. Sometimes the damage is so extensive that only a replacement can fix it, such as:

  • You find extensive water damage or signs of moisture. Water is a powerful force that can weaken the integrity of a structure and breed mold.

  • There has been a recent disaster like a severe storm or tornado or even an extremely harsh winter causing extensive damage.

  • The age of your roof plays a factor when other issues are happening. A new one that is leaking may be a sign of poor installation, but an old one could be at the end of its useful life.
