Replacing a Roof Dome with a Flat Glass Skylight
Check the existing kerb, opening, support and weathering before replacing a roof dome with a flat glass skylight.

Identify what is already there
Record the existing product information if available, but do not use the dome's visible size as the ordering dimension for a replacement. Ask the installer to inspect the opening, support and roof covering. Establish whether the existing kerb will be retained, altered or rebuilt before choosing the replacement unit.

Use the new product's measurement reference
Different rooflights can use different ordering dimensions. The existing unit's label may not describe the reference required by the new designer. Read the selected Stratus or Korniche flat skylight specification and current drawings with your installer. Confirm the finished dimensions, orientation and required fall for that particular system rather than transferring assumptions from the old dome.

Coordinate weathering and internal finishes
Replacing a rooflight can affect the waterproof membrane, insulation and ceiling junction. Agree who is responsible for each part of the work and how the room will be protected while the opening is exposed. A supply-only rooflight order does not include those site tasks. If the support has deteriorated, resolve that before installing the replacement.

Plan lifting, delivery and the final check
Glass units need a handling plan suited to their actual size and weight. Check site access and the route to the roof before arranging delivery. Once the product and support details are approved, enter the confirmed dimensions in the appropriate designer and review the selected glazing. Keep the final order summary and installation documents together for the fitting team.
Compare specifications and configure your rooflight
Have your installer confirm the selected product's ordering dimensions and support details before placing an order. Read the measuring guide and keep the final specification with your project drawings.
