Rooflight installers in St Albans

Builders, roofers and extension companies in and around St Albans 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 Hertfordshire 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 use a rooflight fitting specialist

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.

Covering St Albans and surrounding areas

From the centre of St Albans out to its edges, postcode districts AL1, AL2 and AL4 are all standard cover. The same applies to neighbouring Harpenden, about 5 miles off, and Hatfield, around 5 miles away. If you are further out, towards Hemel Hempstead or beyond, send the postcode and we will confirm before quoting.

Do you need permission in St Albans?

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 St Albans

Do you offer trade rates for builders and roofers?

We carry out subcontract fitting for builders, roofers, extension companies and commercial contractors. Pricing is per job or per schedule of units, agreed in writing before we start. We can work to your programme, fit on your upstand or build our own, and leave the opening ready for the next trade. Send drawings or a unit schedule and we will come back with a trade quote.

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.

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.

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.
