Without a trim or flashing to protect the top edge, water gets in behind the membrane.
Covering Daventry and nearby
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).
What should you expect to pay in Daventry?
Typical range: £245–£695 ex VAT, which is £294–£834 with 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?
Most lantern repairs in England need no approval at all. Where a job turns into a replacement, the Building Regulations 2010 apply and we confirm how the work will be signed off before we start. 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.
