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.

Fitting in Potters Bar and beyond

Postcodes EN6, AL9 and WD6 are the core of our Potters Bar coverage, but they are not the boundary. Addresses in Barnet, East Barnet and Enfield are handled in just the same way, with fitters travelling to each one and travel costs built into the quote before you agree to anything. If you are unsure which side of a boundary you fall on, the full postcode settles it.

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.

Questions about rooflight fitting in Potters Bar

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.

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.

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.

What upstand height and roof pitch does 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.
