What usually causes it?

Access
Roof access, edge protection and permits all affect the plan.
About Daventry and the NN11 area
Leaf fall from garden trees is the most common cause of eaves overflow on suburban extensions. If your lantern sits near trees, clearing the eaves channel each autumn prevents a lot of drips.
Daventry is around 12 miles from Northampton, and both are within our Northamptonshire coverage.
If you're just outside Daventry, we also cover Rugby (9 miles), Northampton (12 miles), Leamington Spa (15 miles).
How much should it cost?
Guide price for commercial roof lantern repairs: £495–£2,995 ex VAT (£594–£3,594 inc VAT), per lantern. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in England?
In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
