Conservation rooflight installation in Sudbury

Rooflight work is weather work. Membranes, primers and sealants all want a dry surface, so a fitting day in Sudbury is planned around the forecast rather than pinned to a date regardless of rain. The opening is kept covered whenever it is exposed, and a roof is not left open overnight without a proper temporary seal. That approach applies to every conservation rooflight we install, from a new opening to a straight swap or a fit-only job. We cover Sudbury, the CO10 district and the rest of Suffolk.

Covering CO10 and neighbouring districts

Looking at a property near Sudbury but not quite in it? We work across CO10, IP7 and IP29 and outwards to Colchester, Haverhill and Braintree. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Sudbury.

Buying your own, or letting us supply

A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a conservation rooflight, photograph it, and tell the seller about any cracks or scuffs, because claims are much easier made early. We will also ask for the model or a link, so we can read the maker's instructions and check the opening size and the flashing kit it expects. If everything lines up, we fit it. If not, we explain what needs changing first.

Included in the work

  • Flashings in lead or a matching kit, dressed to the covering
  • Rooflight set low so it sits close to the line of the roof
  • Slates or tiles lifted carefully and kept for reuse where possible
  • Energy and old roofs — We make sure the rooflight meets current energy rules while suiting an older roof build-up.
  • Listed building consent — We confirm listed building consent is in place before fitting any rooflight on a listed building.

What happens on the day

Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a conservation rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes one day.

Do you need permission in Sudbury?

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.

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, CO10 or a neighbouring district.

Common questions in Sudbury

Will my new conservation 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 make good inside after fitting?

Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.

What if my roof opening is the wrong size for the conservation 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.
