We often take the roof of our house for granted until it starts to get old or cause problems. Most roofs will last for at least 20 years but will eventually need to be replaced. How do you know that you need a new roof? Here are a few common signs that it’s time to replace the roof.

Important Signs You Need a New Roof

1. Age of Current Roof

One important sign that you need a new roof is that your current roof is getting to the end of its lifespan. Take a look at your home improvement records to see when the roof was last replaced and what it’s made of. This will give you some insight into when you need to have it replaced. An asphalt shingle roof should last at least 20 years while other materials may last longer.

2. Check the Shingles

Depending on the area where you live and the weather conditions, your roof may be in poor shape and need to be replaced. Shingles should lay flat against the roof. Check the gutters and downspouts for shingle granules. Once the roof is nearing the end of its useful life, the granules on the surface of the shingles begin to shed. Have the roof inspected periodically and stay on top of maintenance.

3. Plant Growth

Organic growth on the roof is a problem. Plants like moss and algae may grow when there is a moisture problem. This will ruin the roof if left unattended. Use a stiff brush to remove any plant growth and have the roof inspected to determine if any underlying problems need to be addressed.

4. Drooping or Sagging Means You Need a New Roof

The roof should be straight at all times with no drooping or sagging. When the roof has any type of structural damage, it changes its shape. Any sagging spots, especially at the lowest points of the roof, are cause for concern. These could be caused by trapped moisture rotting boards or falling objects like tree branches. Any sign of structural issues should be a concern.

All of these problems do not necessarily mean that you need a new roof. In some cases, you may simply need to have the roof repaired. When you’re not sure if the roof requires replacement or not, order a professional roof inspection.
