Step by step

  1. Note where water stains appear inside - the leak source is often higher up the roof.

  2. For safety, most homeowners should not walk a sloped roof; hire a roofer.

  3. A pro lifts surrounding shingles, replaces damaged ones, and reseals with roofing cement.

  4. Ask them to check the underlayment and flashing near the leak, not just the shingle.

  5. Get photos of the repair and ask about remaining shingle/roof lifespan.

Questions to ask your pro
  • Are you licensed, insured, and experienced specifically with shingle roofs?
  • Will you inspect the underlayment and flashing around the repair area—not just the visible shingles?
  • Can you match my existing shingle color, profile, and manufacturer?
  • Will you provide before-and-after photos of the completed repair?
  • What is the estimated remaining lifespan of my roof based on what you observe?
  • Does the repair come with a workmanship warranty, and for how long?
  • Should I file a homeowner's insurance claim for this damage, or would that affect my rates?
