Rooflight installers in Welwyn Garden City

Builders, roofers and extension companies in and around Welwyn Garden City can bring us in at a single stage: the roof is decked or battened, and the rooflight needs fitting and detailing. We do that work, and we do the same for homeowners directly. Across Hertfordshire it ranges from fit-only installs and old-unit replacements to cutting new openings, setting lanterns on flat roofs and fitting windows into pitched ones. You get one written quote, one company responsible for the fitting, and a contract with S&K Property Investments and Improvement Ltd.

Commercial & trade

Specialist fitting or a general builder

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.

Is your Welwyn Garden City address covered?

Need a rooflight fitted in Welwyn Garden City or close by? Districts AL8, AL7 and AL6 are covered, as are Hatfield, Hertford and St Albans. 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.

Planning and building control

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 Welwyn Garden City

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.

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.

How long does fitting take?

Fitting a rooflight into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.

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.
