4 Steps to Install a Square Skylight in Melbourne Homes

Following are 4 steps required to install a square skylight in Melbourne homes:
  • Marking & Cutting the Opening: Expose the rafters and mark four corners of the opening ‘3 inches’ longer than the skylight's dimensions on the lower and upper rafter edges. Make the opening square, the distances should be equal. At each corner mark, utilize a rafter square to draw lines at right angles up the sides of the rafters to the roof sheathing. Then, drive a long nail through the sheathing and go out on the roof and remove the shingles. Draw an outline of the rafters between the four points, and cut out the drywall. The frame of your skylight should fit inside your lines with about one-fourth inch of space at the sides and three inches at both ends.
  • Joisting Hangers & Headers is essential while installing a square skylight in Melbourne homes: Attach a 3-inch wide joist hanger to each corner of the opening. Match the bottom of the uncut rafter with the bottom of the hanger, and the outer side of the U-shape with the line drawn on the corner hole. Measure and cut four headers. Set one header into each pair of the hangers and fix it to the cut rafter ends. Now, fit the second header into the next pair of hangers and fix it to the first header in a staggered fashion. Fix the flanges of the joist hangers to the second headers with the help of screws.
  • Set the Skylight: Screw 3-inch wide sheathing over the tops of the headers. Put ‘5-inches’ strips of felt and nail them over the headers. Replace the shingles on the bottom and then set your skylight in the opening. Secure the sides with cleats and then replace the roofing over the top and side flanges. Ensure that the nails are set well beyond the flashing edges.
  • How to finish the installation of a square skylight in Melbourne homes: Use finishing nails to secure the frame of the skylight on both the rafters and headers. Cover the headers with drywall and utilize corner beads or wood trims.
