What does skylight replacement in Bow involve?
Our skylight replacement service in Bow covers replacing tired domes and failed glass with a modern rooflight. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written 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. Typical uses for skylight replacement include older extensions due a modern rooflight.
Jobs in Bow 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.
What you can choose
- Misted glass unit replacement only
- Upstand rebuild and insulation
- Fixed to electric opening
- Like-for-like size replacement
- Dome to flat glass upgrade
- Often reuses the existing opening
- Option to add opening and rain sensor
What to check first
- Old glass and domes are disposed of responsibly
- Enlarging the opening changes the structure and may need approval
Consents for skylight replacement in Bow
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
