We carry out flat rooflight and skylight repairs in Watford and across the WD17 area. Flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit.
Signs you need flat rooflight and skylight repairs
- Misted glass
- Ponding on the glass (not enough fall)
- Cracked sealant or a lifted membrane at the upstand
What usually causes it?
No fall
Flat glass needs a slight fall to shed water; ponding stresses seals.
Upstand detail
As with lanterns, the membrane must be dressed up and sealed.
About Watford and the WD17 area
Most inland lantern leaks aren't storm damage; they're usually tired sealant, a lifted capping or blocked eaves drainage. All three are quick to find and fix once you know where to look.
Watford is around 7 miles from St Albans, and both are within our Hertfordshire coverage.
Close by, we also cover Bushey (2 miles), Rickmansworth (4 miles), Borehamwood (5 miles).
How much should it cost?
Typical range: £195–£595 ex VAT, which is £234–£714 with VAT, per rooflight. 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.
