Why the fitting matters as much as the unit
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.
Covering Northampton and surrounding areas
We do not run a branch in Northampton. What we do is send fitting teams to the job, which means NN1, NN2 and NN3 are covered, and so are Wellingborough, Daventry and Rushden. The advantage for you is simple: you deal with one company for the quote, the fitting and the guarantee, wherever the property sits.
Planning and building rules in England
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.
Questions about rooflight fitting in Northampton
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.
Can you fit the rooflight I bought online?
Yes, fit-only is one of our core services. Send the product link or spec, photos of the roof and rough sizes, and we can usually price it from those. Before fitting we check the delivery for damage, which should be reported to the seller, plus the size against the builder's opening and the upstand height. The product warranty stays with the maker or seller, and our guarantee covers the fitting.
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.
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.
