We carry out flat rooflight and skylight repairs in Runcorn and across the WA7 area. Flat rooflights fail in the same places as lanterns: the seal to the upstand, the roof junction and the glass unit.
What you might be seeing
- Misted glass
- Ponding on the glass (not enough fall)
- Cracked sealant or a lifted membrane at the upstand
Why it happens
Upstand detail
As with lanterns, the membrane must be dressed up and sealed.
Unit failure
Edge seals fail and the unit mists.
About Runcorn and the WA7 area
Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.
Runcorn is around 12 miles from Chester, and both are within our Cheshire coverage.
Neighbouring places we cover include Widnes (1 mile), Halewood (4 miles), Huyton (7 miles).
How much should it cost?
Guide price for flat rooflight and skylight repairs: £195–£595 ex VAT (£234–£714 inc 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?
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.

Flat rooflight and skylight repairs in Runcorn: questions

Do you need to visit to price flat rooflight and skylight repairs?
Not always. Clear photos are often enough for a guide price. Where the cause isn't obvious, a visit to inspect and water-test is charged from £145 ex VAT, confirmed before we come.
Do you replace walk-on rooflight glass?
Walk-on glass is a specialist structural unit; we can measure and specify a replacement from the right manufacturer.
Can you fix a Velux-style roof window?
Our focus is flat rooflights and lanterns; pitched roof windows are a different trade and we'll say so if that's what you have.
