When you own a home, maintaining the roof is key to protecting your property and family. If you notice the shingles are curling downward or up, you need roofing services. Here are a few reasons why their condition might change over time.

Why Are My Roof Shingles Curling? 

1. Sun Damage

Shingles have a tar-like coating that prevents them from drying out, curling, and cracking. However, the sun’s ultraviolet rays can eventually destroy the UV-resistant granules that shield the pieces.

When you see asphalt granules in the gutters or on the ground, the materials may be deteriorating. This often happens due to improper attic insulation, which allows heat to build up. If the roof is over 20 years old, the shingles may also be past their natural life span.

2. Insufficient Ventilation

A roof with asphalt shingles has underlying layers of plywood that make the structure durable. However, when moisture builds up due to condensation in the attic, the asphalt begins cupping or curling. This reduces the roof’s life span and leads to mold in your home.

To ensure the moisture and heat can escape, get an attic and roof inspection. Your roofing needs vents to meet building codes and prevent condensation from forming.

3. Improper Materials

Certain types of asphalt are best for extreme heat, while others are meant for cold weather. When shingles designed primarily for heat are installed in Alaska, curling may occur.

Experienced roofing contractors know which products are best for installation. They also identify problems that may occur during manufacturing, such as an incorrect ratio of tar, to help you avoid problems in the future.
