The answer to 'roof repair curling' is that curling or buckling shingles is a common roofing issue that can be caused by a variety of factors. Symptoms include shingles lifting at the edges or in the middle, and the shingles may appear wavy or uneven. Common causes include improper installation, age and weathering, or damage from high winds or hail.
In many cases, minor curling can be repaired by a homeowner, but more severe issues or widespread problems may require a professional roofer. DIY repairs can include re-securing loose shingles, applying roof sealant, or replacing individual damaged shingles. However, if the curling is due to underlying structural issues or if a significant portion of the roof is affected, it's best to call in a professional roofer to assess the situation and provide the appropriate repair solution.
