Skylight repairs & leak fixes for Hemel Hempstead: the essentials
Thinking about skylight repairs & leak fixes in Hemel Hempstead? 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Typical uses for skylight repairs & leak fixes include leaks, condensation, misted units and failed actuators.
Jobs in Hemel Hempstead are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Consents for skylight repairs & leak fixes in Hemel Hempstead
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.

Skylight repairs & leak fixes in Hemel Hempstead: questions
Do you charge for repair visits?
Yes, repairs are charged. We give the price before the visit.
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.
Can you fix a misted rooflight?
A misted unit means the glass seal has failed. The sealed unit, or the whole rooflight, needs replacing.
Do I need to be at home for the survey in Hemel Hempstead?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
