Today, I replaced a leaking skylight for a homeowner. The existing skylight had significant wear and water damage. I carefully removed the old fixed skylight and installed a new Velux vented skylight with energy-efficient glass. I sealed the surrounding area with flashing tape and roofing cement to ensure a watertight fit. I also tested the venting mechanism to ensure smooth operation. The job required using screwdrivers, utility knives, and caulking guns for the precise sealing of the unit. This new skylight will provide better insulation and improve ventilation for the room below.
