Asphalt shingles are one of the most popular roofing materials in the United States, and for good reason. They are durable, affordable, and relatively easy to maintain. However, like any roofing material, asphalt shingles can become damaged over time due to various factors. Knowing the common causes of asphalt shingle damage and when to schedule asphalt shingle repair is crucial for maintaining the integrity of your home’s roof and preventing costly repairs down the line. In this blog, we’ll explore the primary causes and offer insights into when it’s time to call in a professional for asphalt shingle repair.
Common Causes of Asphalt Shingle Damage
Extreme Weather Conditions
-
High Winds: Wind speeds over 50 mph can easily lift shingles, creating gaps and causing them to crack. This leaves your roof vulnerable to water infiltration, which can lead to leaks and rotting of the underlying materials.
-
Hail: Hailstorms are another weather phenomenon that can severely damage asphalt shingles. Even small hailstones can cause dents, cracks, and granule loss, which diminishes the shingles’ ability to protect your home.
-
Heavy Rain: Excessive rainfall can cause water to pool and accumulate on your roof, potentially leading to shingle lifting, water intrusion, and mold growth.
-
Extreme Heat and UV Exposure: Prolonged exposure to the sun’s ultraviolet rays can cause asphalt shingles to dry out, crack, and deteriorate over time. This is especially true for roofs in sunny climates, where heat and UV rays can significantly shorten the lifespan of your shingles.
Poor Installation or Shoddy Materials
Another factor contributing to asphalt shingle damage is improper installation. If your shingles were not installed correctly, they may not provide adequate protection, even from minor weather events.
-
Incorrect Nailing: If shingles are not nailed down properly, they can loosen or even blow off during a storm. Too few nails or the wrong placement can also result in shingles lifting and damaging the roof structure underneath.
-
Subpar Materials: The quality of the shingles plays a significant role in how well they perform. Lower-quality materials may be more susceptible to cracking, fading, and granule loss over time, making them less effective at protecting your home.
Moss, Algae, and Fungus Growth
In areas with high humidity, moss, algae, and fungi can begin to grow on your asphalt shingles. These growths can cause shingles to deteriorate by lifting the granules, which protect the shingles from UV rays. Over time, moss and algae growth can lead to leaks, rotting wood, and structural damage.
If you notice dark streaks or patches of green or black on your shingles, it’s crucial to address the issue promptly. Left unchecked, these growths can cause serious damage to your roof and require costly repairs.
Tree Branches and Debris
Falling tree branches, leaves, and other debris can cause damage to asphalt shingles. When branches scrape against the roof, they can tear the shingles, leaving them vulnerable to further damage from wind and rain. Additionally, debris like leaves can clog gutters, preventing water from draining properly. This can lead to water backup, which may cause shingles to lift or crack.
When to Schedule Asphalt Shingle Repair
-
Missing or Broken Shingles: If you see that shingles are missing or broken, it’s a clear sign that repair is needed. Even a small gap in your roofing can lead to water intrusion and structural damage.
-
Granule Loss: If your gutters are filled with granules from the shingles or if your shingles look thinner, it’s time to schedule a repair. Granule loss weakens shingles and reduces their ability to protect your home.
-
Curling or Buckling: If the edges of your shingles are curling or buckling, it indicates that they are old or damaged. This condition can lead to leaks and other serious problems.
-
Leaks or Water Stains: Water stains on your ceiling or walls are a sign of a leak, and your asphalt shingles may be to blame. Schedule an inspection immediately to prevent further water damage.
Conclusion
If you’re experiencing any of the signs mentioned above, or if your roof is approaching the end of its lifespan, it’s crucial to schedule asphalt shingle repair promptly. Professional services, such as residential roofing services in Houston, can help identify issues and provide the necessary repairs to ensure your roof remains in good condition for years to come.
