Signs of Bad Asphalt Shingles

When it comes to the roof of your home, you want to ensure that it is in good condition to protect your property from the elements. One of the key components of a roof is the asphalt shingles. However, over time, these shingles can deteriorate and become less effective. To help you identify whether your asphalt shingles are in bad condition, here are some signs to look out for.

How Do You Know If Asphalt Shingles Are Bad?

1. Curling or Clawing of Shingles

One of the most noticeable signs of bad asphalt shingles is when they begin to curl or claw. Curling occurs when the edges of the shingles start to lift and become curved, while clawing happens when the edges remain flat, but the middle section starts to rise. These issues can be caused by improper installation, poor ventilation, or old age.

1.1 Causes of Curling or Clawing

Curling or clawing of shingles can be caused by a variety of factors, including improper installation, lack of ventilation in the attic, exposure to extreme temperatures, or poor quality shingles. It is important to address these causes to prevent further damage to your roof.

1.2 Effects of Curling or Clawing

Curling or clawing shingles can leave your roof vulnerable to leaks and damage from moisture. When the edges of the shingles lift, it creates gaps where water can enter, potentially leading to water damage in your attic or interior spaces.

1.3 Actions to Take

If you notice curling or clawing of your asphalt shingles, it is essential to take action promptly. Contact a professional roofing contractor to assess the extent of the damage and determine the necessary repairs or replacement. Ensuring proper ventilation in your attic can also help prevent future issues with curling or clawing shingles.

2. Missing Shingles

Another clear sign of bad asphalt shingles is when you observe missing shingles on your roof. Missing shingles can occur due to severe weather conditions such as strong winds, heavy rain, or hail. It can also be a result of poor installation or aged shingles that have reached the end of their lifespan.

2.1 Causes of Missing Shingles

The primary causes of missing shingles include severe weather events like storms, improper installation, or aged shingles that have weakened over time. Exposure to harsh weather conditions can loosen the roofing materials, causing them to detach from the roof.

2.2 Effects of Missing Shingles

Missing shingles expose your roof to potential water damage and leaks. Without a full coverage of shingles, rainwater can seep into the underlying layers, leading to rotting of the roof deck or damage to the interior of your home.

2.3 Actions to Take

As soon as you notice missing shingles on your roof, it is crucial to address the issue promptly. Contact a professional roofer to assess the damage and recommend the appropriate course of action, which may involve replacing the missing shingles and inspecting the overall condition of your roof.

3. Cracked Shingles

Cracked shingles are another sign that your asphalt shingles may be in bad condition. Cracks can occur due to various reasons, including weathering, thermal expansion and contraction, or inadequate maintenance.

3.1 Causes of Cracked Shingles

Cracked shingles can be caused by a combination of factors, such as exposure to extreme temperatures, hail damage, or the use of poor quality shingles. Additionally, excessive foot traffic on the roof or fallen tree branches can also lead to shingle cracks.

3.2 Effects of Cracked Shingles

Cracked shingles compromise the integrity of your roof, allowing water to penetrate and cause damage to the underlying layers. It can also lead to leaks and potential structural issues if not addressed in a timely manner.

3.3 Actions to Take

If you notice cracked shingles on your roof, it is essential to have them inspected by a professional roofer. They can assess the severity of the cracks and determine whether repair or replacement is necessary. Regular roof inspections and maintenance can help identify cracked shingles early on and prevent further damage.

4. Granule Loss

Granule loss is another indication that your asphalt shingles may be in bad condition. Over time, the granules on shingles can wear away due to weathering, foot traffic, or improper installation.

4.1 Causes of Granule Loss

Granule loss can occur due to various factors, including the age of the shingles, exposure to harsh environmental conditions, or poor quality manufacturing. Additionally, poor attic ventilation can lead to increased heat buildup, causing the granules to detach from the shingles.

4.2 Effects of Granule Loss

When asphalt shingles lose their granules, they become more susceptible to damage from UV rays, leading to premature deterioration. Granule loss can also result in the shingles losing their water-resistant properties, allowing water to infiltrate and cause leaks.

4.3 Actions to Take

If you notice significant granule loss on your asphalt shingles, it is advisable to contact a professional roofing contractor. They can assess the condition of the shingles and determine whether repairs or replacement are necessary. Proper attic ventilation and regular maintenance can help minimize granule loss in the future.

5. Buckling Shingles

Buckling shingles are another sign to watch out for when it comes to identifying bad asphalt shingles. Buckling occurs when the shingles no longer lie flat on the roof surface and appear wavy or uneven.

5.1 Causes of Buckling Shingles

Buckling shingles can be caused by several factors, including improper installation, inadequate ventilation, or excessive moisture in the underlying layers. Poorly installed felt underlayment or the use of wrong-sized nails can also contribute to shingle buckling.

5.2 Effects of Buckling Shingles

Buckling shingles can compromise the overall integrity of your roof, exposing it to potential water damage, leaks, and further deterioration. The uneven surface created by buckling can also become a breeding ground for mold and mildew.

5.3 Actions to Take

If you notice buckling shingles on your roof, it is crucial to consult a professional roofer for an inspection. They can determine the underlying causes and recommend appropriate repairs or replacement. Ensuring proper ventilation and moisture control in the attic can help prevent buckling of shingles.

6. Moss or Algae Growth

The growth of moss or algae on your asphalt shingles is not only unsightly but also an indication of their poor condition. Moss or algae can thrive in moist and shaded areas, potentially leading to damage if left untreated.

6.1 Causes of Moss or Algae Growth

Moss or algae growth on asphalt shingles can be caused by several factors, including excessive moisture retention, lack of sunlight, or the presence of organic debris, such as leaves or branches, on the roof. Poor attic ventilation can contribute to moisture buildup, creating a favorable environment for moss or algae to grow.

6.2 Effects of Moss or Algae Growth

Moss or algae growth can damage the asphalt shingles, causing them to deteriorate at a faster rate. The growth of moss or algae can also trap moisture, leading to rotting of the underlying layers and potential structural damage.

6.3 Actions to Take

If you notice moss or algae growth on your asphalt shingles, it is important to address the issue promptly. Consult a professional roofing contractor who can safely remove the moss or algae and provide recommendations to prevent its recurrence. Improving attic ventilation and regularly cleaning debris from your roof can help control moss or algae growth.
