The answer to 'ridge vent curling shingles' is that this is a common issue caused by improper installation or ventilation problems. When the ridge vent is not installed correctly, it can create gaps that allow air to flow under the shingles, causing them to curl and lift up. This can also happen if the attic ventilation is inadequate, leading to heat and moisture buildup that distorts the shingles.
In most cases, this problem requires professional repair to properly re-secure the ridge vent and ensure adequate ventilation. Attempting a DIY fix may temporarily resolve the issue but could lead to further damage if the underlying cause is not addressed. It's best to have a qualified roofing contractor evaluate the situation and recommend the appropriate solution.
