Question: 1 / 400

What is the correct first step in installing a roof skylight?

Framing the skylight

Cutting an opening in the roof

The first step in installing a roof skylight involves cutting an opening in the roof. This is essential because, before any framing or installation of flashing can take place, you must have a defined space where the skylight will be fitted. Properly identifying and cutting this opening according to the skylight manufacturer's specifications ensures that the skylight will fit correctly and that there will be a proper flow of water away from the opening, preventing leaks.

Framing comes after the opening is established, as you need to ensure that the structural integrity of the roof is maintained around the new opening. Sealing the edges and installing flashing are critical steps that follow the initial opening and framing, as they help provide weather resistance and protect against potential leaks. Therefore, the cutting of the opening is foundational and precedes other installation steps.
