You can expect to keep your roof for anywhere from 20 to 25 years. However, you may have to replace your roof before the 20-year mark. There are several signs that indicate you will need to get a new roof.
Curled Or Buckled Shingles
Your shingles may curl or buckle when they are exposed to moisture. If your shingles are damaged, then your roof will be unprotected. Your roof will be even more likely to suffer damage if there is a storm. That is why it may be time for a roof replacement if the shingles are curled or buckled.
You may be able to get a few shingles replaced. However, if there are several damaged shingles, then it is best for you to get a new roof.
Algae or Moss Growth
Algae and moss can do a lot of damage to your home. If you have algae or moss on your roof, then you likely have a lot of bacteria on your roof. This bacteria can cause a lot of damage to the shingles. You likely have algae on your roof if there are dark streaks on the roof. You can remove moss and algae from your roof, but there is no guarantee that it won’t come back.
Mildew And Mold
Your roof can easily accumulate moisture. All it takes is a little bit of moisture for mold and mildew to grow. Mold and mildew are a health hazard. They can also cause a lot of damage to your roof.
There are a few things that you can do to prevent ice dams from accumulating on your roof in the wintertime. You will need to make sure that the roof is properly ventilated. You will also need to make sure that the roof is adequately insulated. Additionally, you can use an ice and water shield.
However, if an ice dam is already on your roof, then you may need to get a new roof.
Attic Temperature Is Different Than the Outside Temperature
Your attic temperature should be close to the temperature outside. If there is a drastic difference in the temperature, then it is time for you to get a new roof. You may also be able to see daylight through the roof boards.
You should check your roof for leaks. You may notice dark streaks on the roof. You may also notice water leaking inside of your home. Water leaks have a tendency to get worse over time, so you will need to have your roof replaced as soon as possible.
