When Should a Roof be Replaced?

Updated: Mar 4, 2023

There are a few reasons to replace your roof before the damage becomes too obvious. We've compiled a detailed list below to identify different types of damages and how to anticipate when it's time to repair or replace your roof.


Age of Roof

This is an important factor to consider when deciding if you need a simple repair or a full roof replacement. Unfortunately, the older styles of asphalt shingles do not last as long as their warranties would indicate.

Most old-style asphalt roofs start to fall apart after 14 years. If your roof is between 18-20 years old, then it's probably time to replace it.

Shingles are Curling

Curling is the result of the asphalt in the shingles drying and shrinking over time. They become brittle as a result. In high winds, they will begin to get blown off. There is no repair for this other than replacing the tiles affected or, if widespread on your roof, time to replace the whole roof.

Sagging, Holes or Dark Spots

When checking from outside, if you are noticing obvious sagging in one section of your roof, any holes (as a result of damage) or darker spots (missing shingles), this is a clear sign that a roof repair is needed. These damages can escalate to bigger issues leading to major leaking inside the home.

Missing Shingles

This can happen as a result of extreme weather changes as shingles are blown off the roof. If this happens, it means that the shingles have dried, curled and cracked. Obviously, if the shingles are in your yard then they aren't on your roof. If you are finding shingles around your property, it's a sign that the roof requires repair.

If however, you have shingles blowing off after every windstorm, it is most likely that they are not sealed anymore and are deteriorating. This is an indication that a roof replacement is required.

Signs of Water Damage

Signs of water damage are usually obvious, and can be checked while inside your home. Check your walls or ceilings for mold, leaks, water stains and they may be wet to the touch. Water damage is a certain sign that you will need to have your roof checked out and likely repaired.

Can See Daylight Through the Roof Boards

If you can see light through your roof boards, then this is a sign that something is wrong, and you might need to replace your existing roof. To figure this out, check in your attic to see if there are any holes and make sure to check for moisture in the insulation as well.
