To Install Skylights:

  1. The first thing is to get the right skylight. Models with flashing systems are easiest to install and will seal the roof. They are pricier but will save you headaches.To install, find the ceiling joists and mark them well. Use your level to be sure the lines are straight.
  2. Put on your safety goggles. Use the drywall saw to cut along the lines. Remove the drywall from the cut. This gives you an open space to the inside of the roof.
  3. On this opening, mark the inside of the roof to match the opening you just cut.
  4. Mark the corners of the lines by driving nails through the roof to the outside. Place them along the lines you drew to mark where you will cut the roof. Cover the inside of the hole with plastic sheeting. Staple the sheeting well to the inside of the roof. This will catch small pieces of debris that will fall.
  5. On the roof, remove the roofing material that is in between and around the nails.
  6. You now need to “connect the dots” of the nails. Use your pencil to draw the lines on the exposed plywood.
  7. Using the reciprocating saw follow the lines to cut the hole through the roof. Don’t let the large pieces fall through.
  8. Mount skylight brackets per the manufacturer’s instructions.
  9. Carefully position the skylight in the opening. It should be level and fit snugly. Follow the manufacturer’s instructions. All screws should go securely into the rafters.
  10. Add the flashing and the moisture barrier to finish this portion of the job. Now, to begin finishing the inside...
  11. Carefully, remove the plastic sheeting.
  12. The drywall should be flush with the skylight. If not, add drywall as necessary. Add 2x4 studs if needed. Use joint compound and tape to finish.
  13. Prime the ceiling and paint.
  14. Invite your friends over to admire your terrific new skylight.
