One of the most important parts of your home is the roof. It keeps everything inside safe from rain, wind, heat, and snow. But just like every other part of a house, a roof won’t last forever.
A lot of homeowners don’t know their roof is failing until it causes a lot of damage. If you know the warning signs early on, you can protect your property and avoid expensive repairs.
In this guide, we’ll go over the most common signs that it’s time to replace your roof.
Your roof is older than 20 years
One of the best signs that your roof needs to be replaced is how old it is.
Depending on the weather and how well you take care of them, most asphalt shingle roofs last between 20 and 25 years.
If your roof is getting close to that age, it’s a good idea to start making plans to replace it.

The shingles are curling or breaking
Shingles that are in good shape should lie flat and make a strong barrier against water.
Signs to watch out for are:
- Edges that curl
- Shingles that are cracked
- Shingles that are warped or raised
These signs usually mean that your shingles are getting old and need to be replaced.
Shingles that are missing
Without shingles, some parts of your roof are open to rain and wind.
This could cause:
- Leaking water
- Wood that has rotted
- Damage to the structure
It’s important to fix missing shingles quickly after storms so that bigger problems don’t happen.
Roof leaks happen a lot
Sometimes you can fix small leaks, but if they keep happening, it usually means the roof is more seriously damaged.
If you often see water stains on the walls or ceilings of your home, the roof may not be working properly.
If you already have a leak, read our guide on how to fix a roof leak (link).
Granules in the Gutters
Granules in asphalt shingles protect them from damage from the sun and the weather.
Over time, these granules wear away.
Look in your gutters for:
- Granules that look like sand
- Dark bits going down the drain
This means that your shingles are getting worse.
Checking your gutters regularly can also help keep your roof in good shape. You can read our guide on how to clean gutters safely.
Areas of the roof that are sagging
A roof that is sagging is a big problem with the structure.
It can mean:
- Damage from water
- Roof decking that is rotting
- Weakening of the structure
Call a professional roofer right away if you see areas that are sagging.
Bills for energy going up
A roof that isn’t working right can make your home’s insulation less effective.
This could lead to:
- In the winter, heating bills are higher.
- Higher costs for cooling in the summer
If the roof is damaged or the air doesn’t flow well, heat can get in or out of the house.
When is it time to get a new roof?
If your roof has a lot of the problems listed above, replacing it may be the best way to save money.
You can:
- Raise the value of the property
- Make better use of energy
- Stop major water damage
- Keep your home safe for years.
