Shingle curling is a common problem that affects both the appearance and functionality of your roof. Curled shingles can allow water infiltration, reduced wind resistance, and premature roof failure. Understanding why shingles curl and how to prevent it is key to maintaining a long-lasting roof.
At Scaffs India, we provide high-quality architectural and premium designer shingles in Kerala that are engineered to resist curling even in humid and tropical climates.
Common Causes of Shingle Curling
1. Improper Installation
Shingles installed too tightly or too loosely can warp over time.
Incorrect nailing or spacing prevents shingles from lying flat, leading to curling.
2. Poor Ventilation
Insufficient attic ventilation traps heat and moisture, causing shingles to dry unevenly and curl.
3. Low-Quality Shingles
Thin or poorly manufactured shingles are more prone to warping.
Some 3-tab asphalt shingles can curl faster than multi-layered architectural or designer shingles.
4. Age and Weathering
Shingles naturally curl as they age due to UV exposure, heat, and moisture cycles.
Kerala’s humid climate accelerates this process if shingles aren’t designed for tropical conditions.
5. Moisture in Roofing Materials
Wet decking or shingles with high moisture content can expand and curl as they dry.
How to Prevent Shingle Curling
1. Choose High-Quality Shingles
Architectural shingles and Armourshake designer shingles resist curling due to thicker layers and superior materials.
2. Ensure Proper Installation
Correct nailing, alignment, and spacing reduce the risk of curling.
Professional installation ensures shingles lay flat and seal correctly.
3. Maintain Proper Roof Ventilation
Adequate ridge vents, soffit vents, or attic ventilation prevent heat and moisture buildup.
4. Regular Roof Inspections
Detect minor curling early and replace affected shingles before damage spreads.
5. Avoid Low-Quality or Expired Shingles
Use certified shingles designed for your regional climate, especially in humid areas like Kerala.
The Importance of Preventing Curling
Curled shingles not only affect your home’s aesthetics but also compromise:
Wind and storm resistance
Waterproofing and roof deck protection
Shingle lifespan, leading to early replacement costs
Investing in premium shingles and professional installation pays off in long-term durability.
Conclusion
Shingle curling is a preventable problem when you choose the right materials, ensure proper installation, and maintain good roof ventilation. With high-quality roofing shingles in Kerala and professional guidance from Scaffs India, your roof can remain flat, durable, and visually appealing for decades.
