The answer to 'roof repair curling' is that curling or buckling shingles are a common roofing problem, often caused by improper installation, age, or weather damage. Symptoms include shingles lifting at the edges or developing waves or ridges across the roof. Solutions can range from re-sealing or replacing individual shingles to a full roof replacement, depending on the extent of the damage.
For minor curling, homeowners may be able to re-seal shingles themselves, but more significant issues or widespread damage will likely require a professional roofer to inspect and repair the roof properly. Attempting DIY roof repairs can be dangerous and lead to further problems if not done correctly.
