Before committing

SF Builder & Construction
Publishes custom skylight design, site survey, fabrication and installation enquiries.

Soon Heng Glass
Lists glass supply/installation for skylights among its glass applications.
Confirm whether the quote includes roof/opening/frame/sealing work or glass work only, access, making good and total charges.
Clarify the roof opening and approvals before comparing quotes
Ask the contractor to state whether the quote covers a new roof opening, replacement of the whole unit in the existing opening, or glass only. Put roof framing, flashing and sealing, access equipment and making good in separate lines so you can see who is responsible for each part.
BCA’s private-property guidance explains that some minor works are exempt from plan submission and advises consulting your appointed Qualified Person. Ask who will determine whether plans are needed for the actual scope. For a strata property, also ask whether MCST approval is required and who will obtain it before work starts.
Separate a complete roof-opening project from a glass supply or replacement brief. Amber lists dome, roof-tile and openable skylight formats; SF Builder describes custom design, a site survey and fabrication; Soon Heng lists skylights among its glass-installation applications. Those descriptions do not settle structural work, framing, sealing or required permissions. Compare the measured configuration and the exact responsibility for each part of the project.
