Asphalt shingles protect your roof from weather, but they can suffer damage over time. What eats asphalt shingles, and how can you prevent it from happening? Tri-County Roofing explores the common threats that wear down your shingles and compromise your roof’s durability. Understanding these threats helps you keep your roof in top condition.
Weather Extremes: The Primary Culprit
Asphalt shingles face numerous threats from weather extremes, including temperature changes. In climates with wide temperature swings, such as Maryland in the fall and spring, shingles expand and contract constantly. This frequent movement causes shingles to weaken over time, creating tiny fractures that make them more vulnerable to leaks and other damage.
Extreme heat and UV rays further stress shingles by drying them out, leading to cracks that expose the underlayer to additional moisture and sun damage. These combined factors gradually wear down shingles, so regular inspections are essential to catch early signs of weather-related wear.
Moisture and Mold: Hidden Threats
Moisture is a leading cause of shingle damage, especially in humid regions or rainy seasons. In these conditions, “keeping your roof dry” really means minimizing moisture buildup by promoting proper airflow and drainage. Effective attic ventilation allows air to circulate, helping to reduce moisture that may seep in during heavy rain. This circulation prevents lingering dampness that can encourage mold growth under shingles.
Additionally, clear gutters are crucial for drainage, directing rainwater away from the roof and reducing pooling around the edges. When water sits on the roof, even for short periods, it creates a favorable environment for mold and mildew to thrive, potentially damaging shingles and weakening their protective layers. Regular inspections can help ensure your roof has the ventilation and drainage needed to stay resilient, even in persistently wet weather.
Algae and Moss: Unwanted Roof Invaders
Algae and moss often grow on asphalt shingles, especially in shaded, damp areas. Algae create dark streaks on your roof, which can weaken shingles. Moss roots dig into shingles, loosening their grip and letting water seep in. Algae and moss both hold moisture, increasing the risk of water damage. These growths not only affect your roof’s appearance but also reduce its durability.
Tri-County Roofing recommends regular roof cleaning to remove algae and moss before they spread. Proper cleaning and preventive treatments keep your roof looking good and functioning well.
Tree Debris: More Than Just Fallen Leaves
Trees around your home can contribute to shingle damage. Falling leaves, twigs, and branches can harm your roof. Leaves and twigs that collect on shingles trap moisture, creating an ideal environment for mold growth. Heavy branches can scratch or puncture shingles during strong winds. Even minor impacts can weaken shingles and lead to gradual wear over time.
Trimming trees around your property reduces the risk of debris buildup. Regular roof cleaning also helps clear out any debris before it causes damage.
Pests: Birds, Squirrels, and Other Critters
Wildlife can also harm asphalt shingles. Birds, squirrels, and raccoons are known to pull at shingles while searching for food or nesting materials. Some animals chew on shingles or pull them up, creating openings that allow water in. Squirrels and raccoons are particularly notorious for causing damage by prying shingles loose to access attics.
Pest control and preventive measures can help reduce this type of damage. Repairing small roof openings and securing vents prevent animals from accessing the roof.
Poor Installation and Age
Not all shingle damage is caused by external factors; sometimes, it’s due to poor installation or the age of the shingles. Improperly installed shingles can develop gaps, which make them vulnerable to wind and water damage. Additionally, asphalt shingles have a lifespan of 20-30 years, depending on the quality and weather conditions. Older shingles naturally weaken, crack, or curl, making them more susceptible to damage from the elements.
For homeowners facing issues like these, regular inspection and timely repairs are key. A professional inspection can help identify potential issues related to installation or aging. Tri-County Roofing offers thorough inspections to catch problems early, ensuring your roof lasts longer.
Prevention: How Tri-County Roofing Can Help
Regular inspections and maintenance are essential for extending the life of asphalt shingles. Tri-County Roofing recommends scheduling annual roof inspections to catch any damage before it worsens. Timely repairs prevent small issues from becoming costly problems.
Routine cleaning also helps protect shingles from algae, mold, and debris buildup. Additionally, trimming trees and maintaining a pest-free environment protect shingles from damage. Proactive steps like these can add years to the life of your shingles, saving you from unnecessary replacement costs.
