Roof Inspection: Expert Advice


Your roofing requires your attention on a regular basis to ensure it lasts its entire typical lifespan. It’s highly recommended to get your roof inspected twice a year: before and after the winter months. Our roofing experts put together a list of items to look out for on your roof or in your attic.

Key elements to look out for when inspecting your roof

Your roof is one of the most important elements of your home because of all the damages a simple defect can cause to your house’s overall structure. Visual inspection is often enough to identify potential problems. If your roof is easily and safely accessible, here are questions you should ask yourself when checking it out:

  • Does the roof seem to have swelled in one or more places?
  • Is there debris, branches or leaves?
  • Are drains and gutters clogged or in poor condition?
  • Are the joints cracked?
  • Do shingles have a tendency to curl?
  • Is there staining, organic matter or mold?
  • Does water accumulate on the roof for over 48 hours after heavy rain?

Don’t wait for your roof to look like this to get it changed. You’ll avoid costly repairs by getting it done as soon as possible.

The attic: an often forgotten element of a roof inspection

Difficult to access (and probably unwelcoming), the attic is often forgotten during an inspection. Once again, if it’s easy to access safely, inspect it and ask yourself the following questions:

  • Is the air in the attic humid? Or are there areas that are wet?
  • Is there a strong or abnormal smell?
  • Are some roof trusses (structural elements) sagging or shaking?
  • Are there spots, fungi or molds present?
  • After heavy rain, are there watermarks on the materials?
  • Are insulating materials (mineral wool, urethane, etc.) in good condition and properly installed?

Did you answer yes to any of the above inspection questions?

Your attic is likely to be poorly ventilated or your roofing may be in poor condition. It’s time to get your roof inspected by a professional roofer.

Get your roof repaired in a timely manner & save money

A roof that has reached its life expectancy should be replaced. The repair costs associated with water infiltration is often much greater than the cost of a new roof. Here’s an idea of what the average lifespans for various roofing materials are:

Type of roof Lifespan
Asphalt shingles 15 to 25 years
TPO & EPDM 25 to 30 years
Elastomeric membrane 20 to 30 years
Tar & Gravel 15 to 30 years
Metal  50+ years
Slate 75 to 150 years

The lifespans indicated above are for roofing materials that are maintained on a regular basis. If ever replacement is needed, be sure to hire a qualified roofer. Without an official invoice, you can lose your manufacturer’s guarantee. You also won’t be covered by your insurance policy if water damage happens. Of course, to stay on the safe side, be sure not to redo your roof during winter months!
