What To Look For When Considering Roof Replacement

Perhaps you’ve just bought a house or maybe you can’t recall the last time you showed your roof a little TLC.

Knowing when to replace your roof is important when it comes to maintaining the integrity of your home.

We outline a few indications that your roof needs to be replaced.

4 Signs You Need to Replace Your Roof


The shingles of your roof should lay flat against each other. This overlapping pattern prevents the Canadian elements and rodents from sneaking past the roofing barriers and into your attic.

If you have shingles that are sloping up, cracked, or overall damaged, this is strong evidence of you needing your roof replaced.

This said, if there are only a few shingles that are looking a little worse for wear, it’s possible you could get away with repairs, as opposed to a full replacement.

If you’re looking for a roof replacement in Calgary, you can always reach out to a professional for their opinion on which step is more needed.


If you notice a dip or significant sagging in your roof, this can often be a sign of water damage as a result of a leaky roof.

This may be a more complicated fix, but replacing your roof may certainly be an element of the solution.


Seeing moss or other greenery growing on your roof is a likely indicator that the soundness of your roof is compromised. This can occur as a result of moisture being trapped in your roof, which only spells trouble for the inside of your home.


Step into your attic for a moment. If you’re able to see sunlight coming through, either without assistance or by shining a light onto your ceiling, then your shingles are no longer doing their job. Once again, there is a clear risk that water or rodents are able to access the interior of your home.

It’s never a bad idea to get a second opinion from a professional on roof replacement in Calgary, as they have the experience. However, now that you know what you’re looking for, you can proceed with the replacement with more confidence and knowledge!
