Rooflight installers in Holyhead

Every rooflight job in Holyhead has the same core: a correctly sized opening, an upstand or flashing that suits the roof, a unit fixed to the maker's instructions, and a weathertight seal. Around that core the work varies. Fit-only installs, replacements on existing kerbs, new openings with joist trimming, roof lanterns over extensions, roof windows in pitched roofs, and subcontract fitting for trades working in the area. We handle all of it across Gwynedd & Anglesey, with a written quote before work starts and a workmanship guarantee whose terms are on that quote.

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 Holyhead address covered?

Covering Holyhead properly means covering the whole of it, house or business unit, across LL65, LL64 and LL63. Beyond the town, we take on jobs in Caernarfon (19 miles) and Bangor (22 miles) as standard. Each one gets the same survey or photo-based pricing, the same written quote, and the same fitting standard.

Do you need permission in Holyhead?

Welsh rules differ from England's in one important way: rooflights lose permitted development rights in conservation areas, National Parks, AONBs and World Heritage Sites. Elsewhere on a house, a rooflight that projects no more than 150 mm and stays below the highest part of the roof is usually fine. Building regulations still apply to new openings, replacements we fit go through a building notice because we are not scheme-registered, and the energy limit for rooflights is 2.2 W/m²K. A new Welsh Approved Document L takes effect on 4 March 2027.

Questions about rooflight fitting in Holyhead

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.

Do I need planning permission for a rooflight in Holyhead?

Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in Wales. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.

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.

How does payment work?

Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.
