Rooflight installers in Bristol

Builders, roofers and extension companies in and around Bristol 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 Bristol 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.

Why the fitting matters as much as the unit

The joint between the rooflight and the roof covering is where most leaks start. On a flat roof that means turning the membrane up the kerb and terminating it properly under the frame. On a pitched roof it means the right flashing kit, lapped correctly with the tiles or slates. These details are fiddly and easy to rush on a busy build. Giving them to someone focused on fitting the rooflight, rather than treating it as one task among dozens, cuts the chance of a callback.

Is your Bristol address covered?

From the centre of Bristol out to its edges, postcode districts BS1, BS2 and BS8 are all standard cover. The same applies to neighbouring Kingswood, about 4 miles off, and Mangotsfield, around 5 miles away. If you are further out, towards Keynsham or beyond, send the postcode and we will confirm before quoting.

Planning and building rules in England

England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.

Questions about rooflight fitting in Bristol

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.

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.

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.
