Roof Lantern and Skylight Installation Preparation Guide
Use this preparation checklist with your installer before delivery. The manufacturer’s full PDF for the exact product remains the fitting reference.
Before the fitting date
Agree who is responsible for the structural opening, kerb, insulation, roof covering, lifting arrangements and internal finish. Confirm that the roof structure and upstand are suitable for the selected unit. Give the fitting team the final order drawing and manufacturer guide ahead of the day, rather than first showing them the paperwork after unpacking.
Prepare access and storage
Discuss vehicle access, unloading and the route from the delivery point to the roof. Large glazing needs a planned lift with suitable equipment and enough people. Set aside a secure storage area and follow the supplier’s handling instructions. Confirm the delivery arrangements for your order; do not assume a driver will carry glass onto the roof.
Check the delivery
Compare labels and components with the order and packing list. Inspect visible condition before installation, keep identification labels and photograph any concern. Report missing or damaged items promptly through the contact page, quoting the order reference. Keep packaging until the delivery has been checked.
Inspect the finished kerb
Ask the installer to check dimensions, diagonals, support, level or fall, and membrane compatibility against the product drawing. Flat skylights and raised lanterns have different requirements. Do not proceed with an unexplained mismatch, and do not use additional sealant as a substitute for a correctly prepared support.
Use the full installation PDF
The detailed sequence, sealant locations, fixing requirements and glazing orientation are product-specific. These units are not walking surfaces. The installer should arrange safe access and protect people below the opening. Retain photographs of concealed work and the final product labels for the handover record.
Complete the handover
Ask for the applicable care instructions, order specification and warranty information. Keep a record of who fitted the unit and when. Agree how to report an issue and arrange future cleaning safely. If you need help identifying a document, contact us with the product name and order reference.
Choose your product and check its specification
Use the specification for your chosen range, then enter the confirmed measurements and options in its designer. FlatLite configurations are submitted as quotation enquiries.
