Flat rooflight installation in Roehampton

Builders and extension firms in Roehampton often want the rooflight stage of a project handled by a specialist fitting team. We step in once the roof deck or battens are ready, fit a flat rooflight on your upstand or ours, detail it into the membrane or tiles, and leave the opening ready for the plasterer. Homeowners get exactly the same service directly. In each case the job is quoted in writing first, with any access or lifting needs spelt out. Jobs around SW15 and the neighbouring districts are welcome.

Fitting across Roehampton and nearby

Jobs across SW15, SW14 and SW13 are part of our normal cover for Roehampton. 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 Putney and Barnes are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Fit-only or supply and fit

There are two ways to do this. Supply and fit means we source a flat rooflight that suits your roof and install it, so one company answers for both the product choice and the fitting. Fit-only means you buy the unit and we install it. With fit-only, the product warranty stays with the maker or seller, and our written guarantee covers the fitting work. Both routes get the same checks on the opening, the upstand and the maker's instructions before anything is fixed.

What we do on the day

  • Membrane, felt or GRP finished to the frame the way the maker shows
  • Upstand checked or built to the maker's internal and external sizes
  • Unit bedded on the specified sealant or tape and screw-fixed
  • Weight of large panes — We check the weight of the unit against how we will get it onto the roof.
  • Fixed or opening — We ask whether you need ventilation before you settle on a fixed unit.

What happens on the day

On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a flat rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Planning and building rules in England

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 replacements we fit are notified with a building notice, 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.

Getting a price from photos

Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in SW15, and we can price it.

Common questions in Roehampton

Do I need planning permission for a rooflight in Roehampton?

Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in England. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.

What if my roof opening is the wrong size for the flat rooflight?

We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.

What upstand height and roof pitch does flat 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.

Got a unit waiting to go in, or need one sourced? Either way, start with your Roehampton address and a couple of photos.
