The answer to 'drip edge curling' is that curling or lifting of the drip edge is a common roofing problem that can have several causes. Drip edge is the metal flashing installed along the edges of a roof to direct water away from the fascia board and siding. Curling can occur due to improper installation, exposure to the elements, or age and deterioration of the metal.
Some common symptoms of drip edge curling include water leaks, damage to the fascia board or siding, and an uneven or unsightly appearance of the roof edge. Solutions can include re-securing the drip edge, replacing damaged sections, or in some cases, completely replacing the drip edge. Homeowners may be able to address minor curling with DIY repairs, but significant issues or concerns about the roof's structural integrity typically require calling in a professional roofing contractor.
