Replacing a roof lantern starts with assessing the existing upstand: if it is sound, well insulated and high enough, it can often stay. You then measure the upstand, order the new roof lantern and swap old for new on a single dry day. That way the roof does not stay open.
The most common reasons are leaks, condensation between the panes, clouded or yellowed plastic and a frame that feels cold. Sometimes you simply want more light or better glass. If a leak is the reason, find the cause first; it is not always in the roof lantern itself. See what to do if your roof lantern leaks.
If you currently have a plastic dome, the job is slightly different. For that, read replacing a rooflight dome with a roof lantern.
The upstand determines how much work it will be. Check whether the timber or upstand is still sound, whether there are damp patches and whether the insulation connects. If the upstand is too low for the current roof covering, it needs to be raised. A poor upstand is replaced in the same job.
Then measure the external size of the upstand that stays or is coming, at several points. How to do this is explained under measuring up for a roof lantern. If in doubt, send photos or ask us to come round.
With the size you request a quote, which you will have within 24 hours. After approval the lead time is from 2 weeks. The old roof lantern stays in place until the new one is ready. Plan the swap on a dry day and cover the floor and furniture inside, see covering up during building work.
The old roof lantern comes off in one piece or in parts. Take care: glass is heavy and old sealant joints can stick. Then repair the upstand, continue the insulation and have the roofer reconnect the roof covering.
The new roof lantern is lifted, placed and sealed according to the installation instructions. What it will cost you is covered under roof lantern replacement costs.
No. Only if it is sound, dry, solid and high enough. If it is rotten, poorly insulated or too low, replacing it is the sensible choice. Otherwise you lock a new problem under a new roof lantern.
If the new roof lantern is ready before the old one comes off, usually no longer than a working day. If the upstand has to be replaced, it can take longer and temporary cover is needed.
Yes, but the opening then becomes larger and the structure has to be reassessed. Read how to choose the size under choosing roof lantern dimensions.
