Noticing curled shingles on your roof can be concerning for any homeowner. It’s important to understand why this happens to address it properly. Asphalt shingles, popular for their affordability and durability, can develop curling over time. In this post, we’ll explore the causes of asphalt shingle curling and how to address them.
The Culprit Behind Curled Shingles
Several factors contribute to the curling of asphalt shingles. Recognizing these causes is the first step toward a remedy.
Weathering and Age
Asphalt shingles endure harsh weather, especially in areas with extreme temperature changes. The constant expansion and contraction from hot to cold temperatures can make shingles brittle. This leads to cupping, where the center dips, and curling, where the edges lift.
Improper Attic Ventilation
Poor attic ventilation is another cause of shingle curling. Trapped moisture and heat in the attic can damage shingles from below and encourage mold growth, weakening the roof.
Installation Issues
Proper installation is crucial for shingle durability. Using too few nails or placing them incorrectly can loosen shingles and lead to curling. Installing new shingles over old ones or misaligning them can also cause early wear and curling.
Effects of Curled Shingles
Understanding the consequences of curled shingles underscores the urgency of addressing this issue.
Increased Vulnerability
Curling weakens the shingles’ ability to repel water, exposing the roof deck to leaks and water damage. This increases the risk of interior damage and costly repairs later on.
Aesthetic Decline
Curled shingles hurt your home’s curb appeal, which is a concern if you’re planning to sell. A well-maintained roof is essential for protecting your home’s value.
Addressing Curled Shingles
Addressing shingle curling is important. Regular inspections by professionals can catch it early. Depending on the damage, solutions may include repairs or full replacement. Improving attic ventilation and proper installation are key to prevention.
