Cracked or curled roofing shingles are more than just an eyesore—they’re a warning sign of potential roof failure. Understanding why shingles deteriorate in this way can help you prevent costly repairs and extend your roof’s lifespan. In this article, we’ll explore the common causes of cracked or curled shingles and offer effective solutions.
Common Causes of Cracked or Curled Shingles
1. Aging
Shingles naturally degrade over time. Exposure to the elements—UV rays, rain, and temperature changes—breaks down the materials, making them brittle and prone to cracking or curling.
2. Poor Ventilation
Inadequate attic ventilation can cause heat and moisture to build up underneath the roofing system. This accelerates the aging process and leads to the curling of shingles from the bottom up.
3. Improper Installation
Incorrectly installed shingles may not adhere properly, leading to movement and warping over time. Fasteners that are driven too high or off-center can also cause the shingles to lift and curl.
4. Low-Quality Materials
Using substandard or inappropriate shingles for the local climate can lead to early deterioration. Always choose high-quality, weather-appropriate shingles.
5. Multiple Roof Layers
When a new roof is installed over an old one, heat and moisture can become trapped between layers, causing shingles to curl or blister.
6. Extreme Weather
Hail, high winds, and rapid freeze-thaw cycles can crack or lift shingles, especially those already nearing the end of their lifespan.
Solutions for Cracked or Curled Shingles
✅ Regular Roof Inspections
Schedule annual or bi-annual roof inspections to catch minor damage early. This proactive approach can save you from costly repairs down the road.
✅ Proper Attic Ventilation
Ensure your attic is ventilated to reduce heat and moisture buildup. Ridge vents and soffit vents are common solutions.
✅ Professional Installation
Hire certified roofing professionals who follow manufacturer guidelines for installation. This prevents most issues related to faulty workmanship.
✅ Shingle Replacement
Replace damaged shingles promptly. In cases of widespread cracking or curling, consider full roof replacement with higher-grade materials.
✅ Use Quality Materials
Opt for reputable brands and shingles suited to your region’s climate. Architectural shingles, for instance, offer better durability than 3-tab shingles.
When to Consider Roof Replacement
If over 25% of your shingles are cracked or curled, or if your roof is over 20 years old, it may be time for a full roof replacement. A professional roofing contractor can assess the extent of the damage and recommend the best course of action.
