The answer to 'roof decking curling' is that the most common causes are moisture exposure, poor ventilation, and age. Symptoms include uneven or wavy roof surfaces, gaps between boards, and peeling or cracking shingles. Solutions may involve replacing damaged decking, improving ventilation, and ensuring proper moisture control.
In many cases, roof decking curling is a sign of a larger issue that requires professional inspection and repair. While minor curling may be a DIY fix, extensive damage or structural issues should be addressed by a licensed roofing contractor to ensure safety and proper remediation.
