What do flat rooflights in Caterham involve?
Our flat rooflights service in Caterham covers fixed double or triple glazed rooflights for flat roofs and extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. Think of flat rooflights for landings, bathrooms and rear extensions with flat roofs.
From Caterham to Coulsdon, Purley and Redhill, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Caterham
- Square, rectangular or long-format sizes
- Insulated kerb or timber upstand built to suit
- Solar-control or self-cleaning outer pane

Before you order: points to check
- The roof membrane must be dressed up the upstand before the unit goes on
- New openings in an existing roof need a structural check on joists
Consents for flat rooflights in Caterham
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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.

Questions about flat rooflights in Caterham
Double or triple glazing?
Double glazing suits most domestic jobs. Triple glazing improves thermal performance and cuts noise from rain, which is worth it over bedrooms or where the energy calculation is tight.
Will it make the room too hot?
A big unglazed-to-sky area can add solar gain in summer. Solar-control glass, a blind, or pairing a fixed unit with an opening one keeps it comfortable.
Do flat rooflights leak?
A well-fitted flat rooflight should not leak. Leaks almost always come from the upstand or membrane detailing, not the glass unit, which is why the upstand height and the way the roof covering is dressed up and under the frame matter more than the brand.
Do you fit flat rooflights in Caterham?
Yes. We survey and fit flat rooflights in Caterham and across Surrey. Send your postcode and we will offer a survey date when we reply.
