How To Replace A Leaky Skylight

Your skylight should be a talking point that you enjoy in your home. Its purpose is to bring natural light and offer a welcoming feeling so you can enjoy the room that has this brilliant feature. If it is leaking, it is not living up to its full expectation and is making you miserable instead of happy. If you have tried everything to stop the leak, you may have to come to terms with the fact that it needs replacing. Here are step-by-step instructions on how to replace a leaky skylight that anyone can execute.

  1. Remove the surrounding shingles with a pry bar.
  2. Once the flashing is exposed, unscrew and pry off the counter, step, and head flashing from around the skylight.
  3. With a utility knife, remove the ice and water stripping (also known as the membrane) from around the skylight.
  4. Free the skylight by cutting the last little patch of the stripping along the bottom.
  5. Cover the drywall by nailing vinyl strips around the edges.
  6. Place the new skylight in the center of the roof opening.
  7. Secure the new skylight with 2-inch galvanized nails. Be sure to do this through the brackets and onto the roof.
  8. Apply the ice and water stripping.
  9. Apply the flashing and nail them to the sides of the skylight and along the bottom. Cover the flashing with more of the stripping.
  10. Put your shingles back. Be sure to start at the bottom and work your way up. Most importantly, don't nail through the flashing.
  11. On the sides of the skylight, place a piece of step flashing between the shingles. Make sure they are being nailed into the side of the dome.
  12. After installation of the step flashing, install the counter flashing.
  13. Screw the head flashing in place.
  14. Replace the shingles just above the skylight.
  15. Double check everything. Make sure that everything is properly secured, tucked, and nailed down. Be sure that there are no gaps between the skylight and the flashing.
