If you are a homeowner, you may wonder how to know when it’s time for a roof replacement, especially if you’re in an older home. There are signs you can look for that will indicate an aging or failing roof. If you notice any of these problems, you may need a new roof.

Light Coming Through the Roof Boards Means You Need a New Roof

Go up to your attic with a flashlight to check out your roof. Before you turn your flashlight on, look around to see if you notice any light streaming through the boards of your roof. If you can see daylight coming through the boards, water can also get in and damage the structure of your home. Turn your flashlight on, and examine the base of your roof and attic walls. If you see dark stains or streaks, this likely means that your roof is leaking.


Water damage can cause your roof to weaken; if you see sagging areas in your roof while in your attic, use a broomstick to gently poke the area. If the area is soft, wet, or bends easily, your roof has water damage.

Organic Growth

Different types of growths on your roof, such as mildew, mold, algae, and moss may mean it’s time to think about a new roof. Growth happens on roofs that are damp, which leads to rot. Mold and mildew can cause health issues and are signs that you may need a new roof.

Cracked Shingles are a Sign You May Need a New Roof

Wind damage can cause cracks in shingles. If you have a few cracked shingles, you can replace them. However, if there are cracked shingles across your entire roof, it’s a sign that it needs to be replaced.

Missing Granules

Granules help protect your roof from damage. Check your gutters for granules; shingles tend to lose more granules when they are nearing the end of their lifespan. Another sign that the granules on your roof are wearing away is that your roof has inconsistent or darker colors in some areas.

Missing or Broken Shingles

If your roof has broken or missing shingles, it is a sign that your roof is aging. When shingles are broken or missing, your roof is not sufficiently protecting your home and may allow water inside.

Age Determines When You Need a New Roof

Most asphalt roofs last 20 to 25 years. Maintaining your roof is essential to protecting your home from the elements. However, no matter how well it is maintained, it will eventually need to be replaced. Determine how old your roof is so that you’re prepared to replace it before the end of its lifespan.
