What Is a Composition Roof?

A Composition Roof is a roofing system made from a mixture of materials such as asphalt, fiberglass, recycled paper, and mineral granules. These materials are combined to create durable roofing shingles commonly known as composition shingles.

Composition roofing is designed to provide strong protection against rain, wind, sunlight, and changing weather conditions. It is widely used in residential properties because it offers a clean appearance and long-lasting performance at an affordable cost.

One of the main reasons homeowners choose a Composition Roof is its versatility. It comes in different colors, textures, and styles, allowing homeowners to match the roof with the overall design of their property.

Common Problems With Composition Roofs

Even though composition roofing is durable and widely used, some problems may still develop over time due to weather exposure, aging, or lack of maintenance. Identifying these issues early can help prevent expensive roof repairs and extend the lifespan of the roof.

1. Cracked or Curling Shingles

Extreme heat, sunlight exposure, and natural aging can cause composition shingles to crack, curl, or become brittle. Damaged shingles reduce the roof’s ability to protect the home from moisture and weather damage.

2. Roof Leaks

Damaged shingles, broken flashing, or poor roof installation may allow water to enter the structure. Roof leaks can lead to ceiling stains, mold growth, and damage to interior walls if not repaired quickly.

3. Algae and Moss Growth

Moist and shaded areas often develop algae, moss, or dark streaks on the roof surface. Over time, this buildup can trap moisture and slowly damage roofing materials.

4. Storm Damage

Strong winds, heavy rain, hail, and storms can loosen, crack, or completely remove shingles from the roof. Severe weather damage may expose the underlying roof structure to water penetration.

5. Poor Ventilation Issues

Improper attic ventilation can trap heat and moisture inside the roof system. This may reduce the lifespan of composition shingles and increase the risk of mold or moisture damage.

Early inspection and timely repairs help prevent these roofing problems from turning into major structural issues later.
