There will eventually come a time when you need to have a new roof installed on your home. Unfortunately, homeowners often ignore their roof until a problem occurs that requires immediate attention. You should be proactive about roof repair and replacement, so that your home stays safe and secure. Here are some warning signs that tell you when you need to replace your asphalt shingle roof.

Your Roof Has Several Layers

It’s possible that you saved money on a new roof in the past by overlying new shingles on top of your old shingles. This is a common technique known as a roof overlay, and it’s an acceptable way to add new shingles to a roof. The problem with a layover roof is that you can only use the technique so many times.

In general, you shouldn't have more than two layers of asphalt shingles on your roof. Any more than two layers, and you could have problems with too much weight on the roof. When a problem occurs, you should be prepared to rip off both layers of asphalt shingles and start from scratch.

Your Shingles Have Noticeable Wear

Asphalt shingles have some clear warning signs that they are approaching the end of their lifespan. Thankfully, you can identify some of them on your own by doing a simple inspection.

Loose Granules
Be on the lookout for granules that came off of your shingles. You can easily check this by going up to your gutters and seeing how many granules have collected inside of them. If you only see very few granules then everything should be fine. Your shingles are still holding up and should not be in need of replacement.

However, be concerned if you notice large amounts of granules in the gutter. All of these granules came from the shingles located above the gutters, and a lack of granules means the roofing material has less protection. If one section of roofing material has more granule loss, then you could replace a specific section. Large granule loss throughout the entire roof means you'll need to have the material replaced in the near future.

Curling Shingles
You can also identify shingles that have a curved edge along the bottom. This edge can be hard to identify from the ground, so it helps to take a close look up on a ladder. Upward curves indicate that the shingles are not forming a tight seal with the roof. Once again, this can be repaired if the damage is small, but curling across the entire roof will require replacement.

Your Attic Has Moisture

The exterior of the roof may look fine, but your attic will tell another story. Inspect your attic for signs of moisture, which can be in the form of mold in the insulation due to a leak. The eaves of the roof may even have watermarks that indicate water has somehow been getting in.

The watermarks are strong indicators that there is a leak on the exterior of the roof. Once you find the damaged section of shingles that is allowing in water, look for similar-looking sections elsewhere on the roof. This will help determine if you need complete replacement.

Your Roof is Old

Sometimes it is best to gauge roof replacement by how old the roof is. Asphalt shingles should last between 15 and 20 years. Consider getting a professional roof inspection for an older roof to find out what could be wrong with it.
