What this means for your roof
Owens Corning describes a trim-and-patch procedure for raised membrane wrinkles and points to moisture and deck spacing as possible causes. Restoring flatness alone does not explain why the wrinkle formed. The bulletin’s cement and primer terminology should be clarified with the manufacturer before selecting patch-treatment materials.
A useful question for your contractor
Ask what caused the wrinkle and request the approved repair detail and photographs before the roofing covers it.
Ask for the answer to be tied to the actual roof condition and the exact product being installed. Keep the agreed repair or installation detail with your estimate and project photos.
