The answer to 'drip edge curling shingles' is that curling or lifting of the drip edge can cause shingles to curl and lift as well. This is a common issue that can be caused by improper installation, weather exposure, or other factors. Curling shingles can lead to leaks, water damage, and other roofing problems if not addressed.
The drip edge is a crucial component that helps direct water away from the roof's edge and protect the underlying roofing materials. If the drip edge is not installed correctly or becomes damaged over time, it can cause the shingles above it to curl and lift. This can be a DIY fix in some cases, but it's generally best to have a professional roofing contractor inspect and repair the issue to ensure it's done properly and safely.
