Sliding rooflight installation in Plumstead

Builders and extension firms in Plumstead 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 sliding 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 SE18 and the neighbouring districts are welcome.

Where our fitters travel

Jobs across SE18, SE2 and SE28 are part of our normal cover for Plumstead. 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 Woolwich and Abbey Wood are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Already bought your unit?

If you have bought a sliding rooflight yourself, we check four things before fitting. First, the delivery: open it, look for chips, cracks and bent frames, and report any damage to the seller straight away. Second, the size, measured against the builder's opening rather than the external frame. Third, the upstand height above the finished roof. Fourth, the maker's instructions, which set the fixings and sealing. Product warranty claims go to the seller and maker; our guarantee is for how it was fitted.

Included in the work

  • Full open and close cycle checked before handover
  • Cable routed to the motor, ready for the electrician's final connection, quoted as a separate line
  • Lifting plan for the unit, often with gear booked for the day
  • Guarding on the terrace — We look at how the roof terrace will be guarded before the rooflight is fitted.
  • What the glass slides over — We check the area the glass will cover when open before deciding where the unit goes.

Fitting your sliding rooflight, step by step

Where a job takes one to two days, the split is usually structural work first and finishing second. Early on, the fitters cut or prepare the opening, trim where needed and prepare the upstand or flashing. Then a sliding rooflight is lifted in, fixed and made weathertight so the roof is sound before anyone moves inside. Plasterboard, trim and filler for the reveal come after. Each evening the work area is swept, and at the end the glass is cleaned and the team talks you through what was done.

Regulations for Plumstead properties

Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.

Before you get in touch

Keep it simple. Two or three photos, outside and inside. Approximate sizes. What the roof is made of. Anything awkward about getting up there, such as a conservatory below, a narrow side path or no parking. If you bought the rooflight online, the link or model name. Then your postcode in or around SE18. That is enough for a first price.

Common questions in Plumstead

Do you make good inside after fitting?

Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.

Does a rooflight need building regulations approval?

A new opening usually needs building regulations approval. A replacement is a controlled fitting: it must be self-certified by an installer registered with a competent person scheme or notified to building control. We are not registered with a scheme, so replacements we fit are notified to building control with a building notice, and the council's fee is shown on your quote.

What if my roof opening is the wrong size for the sliding 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.
