The answer to 'roof inspection curling' is that curling or buckling shingles are a common sign of roof damage or deterioration. Curling shingles can be caused by a variety of factors, including age, poor installation, inadequate ventilation, or damage from weather and UV exposure. Symptoms of curling shingles include the edges of the shingles lifting up or the center of the shingles becoming raised or cupped.
In many cases, curling shingles indicate that the roof is nearing the end of its lifespan and will need to be replaced soon. However, in some cases, the curling may be limited to a few shingles and can be addressed with minor repairs. If the curling is widespread or accompanied by other signs of damage like missing granules or leaks, it's best to have a professional roofing contractor inspect the roof and provide recommendations for repair or replacement.
