Pre-installation checks and preparation
Before installation, inspect the roof structure to ensure it is sound and capable of supporting the window weight. Confirm that flashing and weatherproofing materials appropriate for your roof type are available. Check that the surrounding roof area is clear of debris and that access for installation is safe. Ensure you have the correct installation instructions for your specific roof construction, as fitting methods vary between pitched timber roofs, concrete and other structures. If you are unsure about any aspect of the installation, consult a qualified roofer or surveyor.
