Skylight repairs & leak fixes for Bow: the essentials
Thinking about skylight repairs & leak fixes in Bow? The short answer: leak tracing, resealing, actuator repairs and glass replacement. The longer answer depends on your roof, which is why we survey before we price.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. In Bow, as anywhere, skylight repairs & leak fixes are the usual choice for rooflights that have stopped opening or started dripping.
From Bow to Stratford, Hackney and Leytonstone, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for skylight repairs & leak fixes in Bow
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Skylight repairs & leak fixes in Bow: questions
Can you fix a misted rooflight?
A misted unit means the glass seal has failed. The sealed unit, or the whole rooflight, needs replacing.
Is it condensation or a leak?
Condensation forms on the inside face on cold days and comes back in the same pattern. A leak appears when it rains and often tracks down the reveal.
Why is my skylight leaking?
Common causes are a failed seal, a membrane that has split or lifted at the upstand, a low upstand, blocked drainage or condensation mistaken for a leak.
