Many roofing contractors also offer gutter services to complement their roof work. Not every leak will require the same amount of time for repairs. If you have a smaller leak, most professionals will be able to patch the problem area in around 30 minutes. The contractor may also determine that other roofing maintenance—such as inspections and debris removal—should be performed at the same time.
