Frameless rooflight installation in Stevenage

A rooflight is not finished when the roof is watertight. The inside matters too: the reveal or lining around the opening, the plaster, the trim where it meets the ceiling. Some installers leave that for somebody else. When we quote for frameless rooflight installation in Stevenage, internal finishing is listed so you can see whether it is included or left for your decorator. That way a frameless rooflight looks right from the room below as well as from outside. We cover Stevenage and properties throughout Hertfordshire.

Guide ranges for supply & fit. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building control fees, where a job needs them, are shown as their own line.

Where our fitters travel

If you also own a property or a business unit in Hitchin, Letchworth Garden City or Welwyn Garden City, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and SG1, SG2 and SG4 sit comfortably within that pattern.

Buying your own, or letting us supply

If you have bought a frameless 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.

What the job includes

  • Kerb squared across the diagonals before the glass is ordered or fitted
  • Upstand built to the maker's drawing within its stated tolerance
  • Fall set in the upstand so rain clears the oversailing glass edge
  • Laminated inner pane — We confirm the inner pane is laminated or otherwise suited to being overhead.
  • Drainage at the overhang — We check how water leaves the glass where it oversails the kerb.

How a fitting day runs

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 frameless rooflight: one day, weather permitting.

Do you need permission in Stevenage?

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.

Getting a price from photos

A fast quote needs five things: a photo of the roof from outside, one from the room below, rough sizes of the opening or the space, the roof covering (felt, single-ply, fibreglass, tiles, slate or metal), and a note on access. If you have already bought the unit, add the product link or spec sheet. And give us the postcode, SG1 or a neighbouring district.

Common questions in Stevenage

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.

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 is included in the price?

The written quote lists it line by line. Typically that covers fitting labour, fixings, sealants, membrane or flashing materials, any upstand work, internal finishing if agreed, and taking away the waste. For supply and fit, the unit itself is included too. Scaffold, lifting gear and any third-party fees, where needed, are shown separately so you can see what each part of the job costs.
