The answer to 'architectural shingles curling' is that curling is a common issue with architectural shingles, often caused by improper installation, poor ventilation, or natural weathering. Symptoms include the shingles lifting at the edges or developing a wavy appearance. Solutions can include re-nailing the shingles, improving attic ventilation, or in severe cases, replacing the affected shingles.
Homeowners should first inspect the roof to determine the extent of the curling and its underlying cause. Minor curling may be a DIY fix, but more significant issues or a widespread problem often require the expertise of a professional roofing contractor to properly diagnose and resolve the issue.
