We carry out flat roof junction and flashing repairs in Shirley and across the B90 area. The junction where the flat roof covering meets the lantern kerb is a weak point on many extensions.

What you might be seeing
- Splits, blisters or lifted edges in the roof covering by the kerb
- Missing or loose edge trims and flashings
- Ponding on the roof next to the lantern
What usually causes it?
Unbonded membrane
EPDM or single-ply that has come away from the kerb lets water run behind it.
Missing trims
Without a trim or flashing to protect the top edge, water gets in behind the membrane.
Roof lanterns in Shirley
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.
In built-up areas, access is often the hardest part of the job — through the house, over a neighbour's roof, or with parking restrictions. We plan access in advance and price any tower or scaffold into the quote.
Shirley is around 6 miles from Birmingham, and both are within our West Midlands coverage.
If you're just outside Shirley, we also cover Solihull (2 miles), Birmingham (6 miles), Smethwick (8 miles).
What should you expect to pay in Shirley?
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?
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.
