About roof repair

Most roof repairs fix one problem: a leak, a few missing shingles, a cracked boot around a pipe, or flashing that has pulled away from a wall or chimney. A good repair starts with finding where the water gets in, which is often not where it shows inside. Small repairs done early keep a roof going for years. A roof with many leaks or worn shingles across its whole surface may be past repair.

What to ask a contractor

  • Where exactly is the water getting in, and how did you find it?
  • Is this a one-off fix, or a sign the roof is near the end of its life?
  • Will you match the existing shingles, and what if they are no longer made?
  • Is the repair covered by a warranty on your work?
