Covering SE10 and neighbouring districts
Jobs across SE10, SE8 and SE14 are part of our normal cover for Greenwich. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Lewisham and New Cross are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.
Included in the work
- Supplied units checked against your schedule before fitting
- Flat rooflights fitted, sealed and trimmed on your kerbs
- Upstands built by us where you would rather not
- Upstand ready and to size — We ask for the upstands to be built to the maker's drawing before we arrive.
- Who weathers the roof — We agree who turns the roof covering up the kerb before we book.
Fitting your rooflight, step by step
Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a rooflight: half a day to a day per unit, weather permitting.
Do you need permission in Greenwich?
Replacing a rooflight in an English home is a controlled fitting: it has to be self-certified by a scheme-registered installer or notified to building control. We are not registered with a competent person scheme, so on trade replacements we agree up front who notifies building control, and the new unit has to meet current energy limits. Adding a new one usually means a building regulations application, because joists or rafters are trimmed. On the planning side, most house rooflights are permitted development if they project 0.15 m or less; on a side slope the glass must be obscured and fixed unless the opening part is over 1.7 m above the floor.
Help us quote accurately
What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around SE10 and we will come back with a quote or a survey date.
Common questions in Greenwich
Do you need scaffolding to fit a rooflight?
Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.
What upstand height and roof pitch does rooflight fitting need?
It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
Will my new rooflight leak?
A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your quote.
