"Skylight" and "roof window" are often used interchangeably, and the installation principles are the same — this is about doing it properly, whatever term you use.
What Makes the Difference Between a Good and Bad Installation
The visible glass is the easy part. What actually determines whether a skylight performs well long-term is the structural opening beneath it and the flashing detail around it — neither of which you'll see once the job is finished.
What We Check Before Installing
- Roof pitch and whether it suits the specific skylight model
- Structural capacity of the surrounding rafters
- The best position for genuine usable light, not just the easiest spot
- Access requirements for the installation itself
Our Skylight Installation Process
- Assess the roof and room below. Confirming pitch, structure and the best position for light.
- Form the opening properly. Supported correctly, not just cut to size.
- Fit with correct flashing. The detail that determines whether it stays watertight long-term.
- Finish and test. Checking the seal and finishing the reveal to a proper standard.
