Why Do Roof Shingles Curl?

Many things can make shingles curl. Understanding these reasons helps us prevent curling. It also helps us fix it correctly.

1. Age and Weather

Shingles get old just like us. Over time, sun, rain, and snow wear them down. The sun’s hot rays can dry out the shingles. This makes them brittle. Then, they start to curl. Also, strong winds can lift the edges of shingles. This also makes them curl. Similarly, heavy rain can seep under the shingles. This can make them warp and curl.

2. Poor Ventilation

Our attics need to breathe. Good airflow helps keep the roof cool and dry. If there is not enough airflow, heat and moisture build up. This hot, moist air rises up and can make the shingles curl from underneath. Proper ventilation is very important for a healthy roof. It helps keep the shingles flat and working well. Additionally, good ventilation also helps prevent ice dams in colder climates.

3. Improper Installation

Sometimes, shingles are not put on correctly. If they are not nailed down right, they can move. This makes them curl. Also, if the underlayment, which is the layer under the shingles, is not installed correctly, it can trap moisture. This can make the shingles curl. Furthermore, using the wrong type of nails can also contribute to curling.

4. Multiple Layers of Shingles

Some homeowners put new shingles over old ones. This is not a good idea. Too many layers trap heat. This heat makes the shingles curl. Also, the added weight can stress the roof structure. Therefore, it is always best to remove old shingles before installing new ones. This ensures a proper and long-lasting roof.

How to Fix Curling Roof Shingles

Fixing curling shingles depends on how bad the damage is. Sometimes, we can fix individual shingles. Other times, we need to replace a larger area.

1. Replacing Individual Shingles

If only a few shingles are curled, we can replace them. First, we carefully remove the damaged shingle. Then, we clean the area underneath. Next, we put a new shingle in its place. Finally, we nail it down securely. Moreover, we must use roofing nails and seal the edges with roofing cement.

2. Repairing Minor Curling

If the curling is not too bad, we can try to flatten the shingles. On a warm, sunny day, the shingles will be more flexible. We can carefully press them down. Then, we can use roofing cement to glue them back down. However, this is only a temporary fix. It is not a good solution for severely curled shingles.

3. Replacing a Section of Shingles

If many shingles in one area are curled, we need to replace that whole section. This involves removing all the damaged shingles. Then, we install new underlayment and new shingles. This is a bigger job. It might be best to ask a grown-up for help. In addition, this will ensure the repair is done correctly.

4. Preventing Future Curling

To stop shingles from curling again, we need to take some steps. We should make sure our attic has good airflow. We should also check our roof regularly for damage. Additionally, we should clear away any leaves or debris that build up on the roof. This helps prevent moisture buildup.

More Tips for a Healthy Roof

Keeping our roof healthy is very important. Here are some extra things we can do.

Regular Inspections

We should check our roof a couple of times a year. We should look for missing, cracked, or curled shingles. We should also look for any signs of leaks. Early detection can prevent big problems. Furthermore, inspecting after storms can help us find damage quickly.

Cleaning the Roof

We should clean our roof regularly. We should remove leaves, branches, and other debris. This helps prevent moisture from getting trapped. It also helps prevent moss and algae from growing. Additionally, keeping the roof clean makes it look nice.

Professional Help

Sometimes, roof problems are too big for us to fix. In these cases, we should ask a grown-up or a roofing professional for help. They have the tools and experience to fix big problems safely. Therefore, it is always best to seek professional help when needed.

FAQ

Besides curling, other signs of shingle damage include missing shingles, cracked shingles, and granules (the small colored pieces on the shingle surface) in the gutters. These granules protect the shingle from UV rays. When they fall off, the shingle is more vulnerable to damage. Additionally, blistering or buckling of shingles can also indicate a problem.

Proper ventilation helps regulate the temperature and moisture levels in the attic. This prevents excessive heat buildup in the summer and moisture buildup in the winter. Both of these conditions can shorten the lifespan of shingles. Good ventilation keeps the shingles cooler and drier, which helps them last longer. Furthermore, it helps prevent ice dams in colder weather.

The underlayment is a protective layer installed directly on the roof deck before the shingles. It acts as a secondary barrier against water intrusion. If shingles are damaged or missing, the underlayment helps prevent leaks. It is a very important part of the roofing system. In addition, it helps protect the roof deck from moisture damage.

A roof should be inspected at least twice a year, ideally in the spring and fall. These inspections help identify any potential problems before they become major issues. Additionally, it is a good idea to inspect the roof after severe weather events, such as storms with high winds or heavy hail. Regular inspections can extend the life of a roof.

Yes, curled shingles can definitely cause leaks. When shingles curl, they create gaps and openings that allow water to seep underneath. This water can then damage the roof deck and even leak into the house. Therefore, it is important to address curling shingles promptly to prevent leaks and further damage.

Some common mistakes include using the wrong type of nails, not sealing the edges of new shingles properly, and not addressing underlying issues like poor ventilation. These mistakes can lead to further problems and shorten the lifespan of the roof. Furthermore, walking on the roof incorrectly can also damage the shingles.
