Step 3. Use a curb-mounted skylight if the roof pitch is less than the ratio of 3 to 12 and a deck-mounted skylight if it is more than the ratio of 3 to 12.

Locate the Rafter and Create a Rough Opening

Step 4. After determining the skylight placement, find the rafters from the stud finder and mark the locations between the rafter base for the rough opening.

Step 5. Frame the rough opening based on the selected skylight parameters. Run the screw in all corners of the rough opening. But the screw should be long enough to penetrate the roof completely so that the outline of the frame is easy to find.

Prepare the Roof

Step 6. Remove the shingles inside of and 6 to 12 inches outside of the screws. Snap a line to mark the beginning of the skylight using the chalk line and screw based on the guide and then remove the screw.

Step 7. Cut the opening for the skylight with a circular saw. Protect the part you are cutting so that it does not get inside. Cut a 6-inch ceiling underlayment on all sides of the opening. This will give the ice and water shield space to stick to the decking around the opening.

Install Skylight

Step 8. Remove the cladding from the skylight by pulling the sides and down from the skylight. Now put the skylight on the starting part and keep it in the middle. Use the following skylight based on the guide. After focusing on the skylight opening, nail it in place with a flange.

Finish with the top following the same procedure to install the ice-water shield on the sides.

Add the Sill and Step Flashing

Step 10. Install the bottom row of the shingles. Place the sill flashing on the bottom edge of the skylight. Protect it with ceiling nails. Once the sill flashing is secured, start interweaving the step flashing and shingles, from both sides to the top. Cut to fit the final part of the step flashing if it is too long.

Step 11. A solar panel should be connected to the body of the skylight if the solar-powered venting skylight is installed. Replace the cladding around the skylight’s body after the step flashing and shingles are installed all the way.

Step 12. Install the saddle flashing around the top of the skylight, with cladding in place.

Now finish the shingling of the remaining ceiling above the skylight.

Sync the Skylight
