Your roof is a vital part of your home and protects it from the elements. It's important to keep track of how well it's performing and when the time has come to replace it. Knowing the signs can help you decide if you need a roof replacement or minor repairs. Here are nine key signs that it's time for you to replace your roof.

1. Missing or Leaking Shingles

One of the most obvious signs it's time to replace your roof is missing or leaking shingles. If you can see gaps in your roof where shingles are missing, or if water is finding its way into your home during rainstorms, then it's time to think about replacing your roof.

2. Curling or Cracked Shingles

If the edges of your shingles are curling up, cracked, or broken, then it's a danger to the roof. This is a sign of age and weathering and can leave your home vulnerable to further damage from rain, snow, and wind.

3. Old Age

Knowing the age of your roof can provide an important hint about whether you need to replace it. According to Bob Vila, asphalt shingle roofs typically last 15 to 30 years, so if your roof is older than that, then it's a good idea to call in professional roofers. You may also want to consider installing a new roof even if yours isn't too old, as heavy weather can take a toll on even newer roofs.

4. Sagging Roof Deck

If you can visibly see that your roof is sagging in the middle or at one end, then it means there's been some damage to the structure itself. You'll need to call in professional roofers to inspect it. This is a sign that the decking underneath the shingles is weak or compromised. Unless you fix the decking, the sagging roof will eventually collapse.

5. Dark Streaks

Dark streaks on the roof are not something to ignore. It's a sign of algae called Gloeocapsa Magma, according to Bionity.com, that can feed off the limestone found in shingles and cause damage over time. Professional cleaners can get rid of this algae. However, if they're unable to do so or if you notice that the streaks are reappearing quickly, then it's a sign that it's time to replace your roof.

6. Excessive Sunlight

Do you see sunlight coming through your roof boards? If so, then it's a sign of serious damage, and you should consult professional roofers. Holes in the roof can result from storms or animals and cause major damage to your home if not addressed quickly.

7. Higher Energy Bills

If you notice your energy bills are getting higher monthly without any clear explanation, then it might be time to replace your roof. Your roof helps to keep the temperature in your home regulated, so a worn-out or damaged roof can make it harder for your heating and cooling system to maintain the temperature you want.

8. Wet Spots on Ceilings and Walls

It's no secret that roofs can leak, and a wet spot on the ceiling or wall is a sure sign that your roof isn't doing its job. The leaks often start by the chimney or in the roof corners and can spread over time if not addressed. Instead of wet spots, you may notice dark stains on your walls or ceiling. This staining is a sign that the roof has been leaking for some time.

9. Pests Inside the Home

When people think of pests entering the home, they may not realize the roof is a potential entryway. Some pests can chew or claw through wood and other materials. As they bite through wood, insulation, and other foundation elements, it leaves behind damage to the roof. That damage is a precursor to the further damage such vermin can bring to other parts of the home. You'll most likely know pests are coming through the roof if you see them in the attic or other upper sections of your home.
