Why the fitting matters as much as the unit
Product warranties on rooflights usually depend on the unit being fitted to the maker's instructions. Those instructions cover upstand height, fixing centres, sealants, and how the roof covering is dressed in. Following them line by line takes familiarity with how different units go together. A specialist fitter reads the paperwork, checks the delivery and measures the opening before starting, then fits to the book. If something on site does not match, they flag it rather than improvising. That protects both the roof and the warranty.
Nearby towns we also cover
Postcodes OX18, OX28 and OX8 are the core of our Carterton coverage, but they are not the boundary. Addresses in Witney, Oxford and Abingdon 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 Carterton
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.
What if my roof opening is the wrong size for the rooflight?
We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.
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.
