Questions from Sandown
Does a longer lantern need extra support?
Long lanterns use intermediate rafters inside the lantern itself. The roof structure around the opening must be designed to carry the lantern's weight; your builder or engineer sizes the trimmers.
Can a rectangular lantern be made to an exact size?
Yes. Made-to-measure lanterns are built to the external kerb size you give us, usually in 10 mm steps within the range's limits. Made-to-measure takes longer than a stock size and cannot be cancelled once ordered, so measure twice.
Can you fit a roof lantern in Sandown?
We can quote for fitting where we have cover. Send your postcode and photos of the roof and kerb, and we will confirm before quoting.
How quickly can I get a roof lantern in Sandown?
Stock sizes are typically ready in 5–10 working days, made-to-measure in 3–4 weeks, plus delivery. Your quote gives the date for PO36.
