Rooflight installers in Portsmouth

Homes and commercial buildings in Portsmouth need different things from a rooflight. A kitchen extension wants a lantern or flat glass rooflight that brings in daylight and holds on to heat. A warehouse may need old domes replaced, smoke-vent rooflights renewed, or an access hatch fitted for maintenance. We work on both sides across Hampshire, covering fit-only, replacement, new openings and trade fitting for contractors. The fitting principles do not change: right opening, right upstand, maker's instructions, sound weather seal.

Where rooflight jobs go wrong

Builders run many trades at once, and the rooflight often gets squeezed in between the roofer and the plasterer. That is when corners get cut: an upstand built a little low, sealant applied in damp conditions, a reveal left rough. Bringing in a fitting specialist for that one stage means someone is focused on it alone, following the maker's instructions, with time set aside to finish the inside properly. The builder keeps control of the programme, and the rooflight gets proper attention.

Postcodes and places we cover

Need a rooflight fitted in Portsmouth or close by? Districts PO1, PO5 and PO2 are covered, as are Southsea, Gosport and Fareham. If you manage several properties across these places, we can quote them together and plan the fitting days so the route makes sense. Larger units or awkward access at any of them are planned for at quote stage, so the day itself runs to plan.

Do you need permission in Portsmouth?

In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.

Questions about rooflight fitting in Portsmouth

Can you replace an old dome without redoing the whole roof?

Usually, yes. If the existing kerb is sound, level and tall enough, a new unit can often sit on it with a fresh seal to the roof covering. If the kerb is rotten or too low, we rebuild it and patch the covering around it rather than stripping the whole roof. This is checked at the survey and included in the written quote, so you know the full scope first.

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.

How does payment work?

Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.

Can you remove and dispose of the old rooflight?

Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.
