We carry out flat roof junction and flashing repairs in Crowthorne and across the RG45 area. The junction where the flat roof covering meets the lantern kerb is a weak point on many extensions.
Is it time for flat roof junction and flashing repairs?
- Leak near the lantern but not from the frame
- Splits, blisters or lifted edges in the roof covering by the kerb
- Missing or loose edge trims and flashings
Why it happens
Cracked GRP
Fibreglass roofs can crack at the kerb corner where movement concentrates.
Missing trims
Without a trim or flashing to protect the top edge, water gets in behind the membrane.
Covering Crowthorne 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.
From Reading to Crowthorne is roughly 10 miles — all part of the Berkshire area we cover.
We also cover nearby Sandhurst (2 miles), Yateley (2 miles), Camberley (3 miles).
How much should it cost?
Guide price for flat roof junction and flashing repairs: £245–£695 ex VAT (£294–£834 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?
Straightforward repairs — resealing, gaskets, cappings, eaves and like-for-like parts — don't normally need building regulations approval in England. Replacing the whole lantern or enlarging the opening is different and falls under the Building Regulations 2010; we confirm in writing which route applies before any replacement. 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.

Can you repair a GRP roof without it showing?
Repairs are colour-matched as closely as possible, but new topcoat next to weathered topcoat can look slightly different at first.
