What drives repair price

  • Access. Steep and tall roofs need more safety setup.
  • Matching. Old discontinued shingles are hard to match and may need a wider section replaced.
  • Hidden damage. Wet decking under a leak often adds a few sheets.
  • Minimums. Most roofers charge a trip minimum even for tiny jobs.
