How we approach skylight installation in Limavady
We handle skylight installation across County Londonderry, including Limavady. In short: survey, supply and fit — new openings, extensions and fit-only work. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many Northern Irish homes have later flat-roofed kitchen extensions where an old dome can be swapped for glass. Typical uses for skylight installation include new extensions, new openings and fit-only jobs.
Limavady is around 24 km from Derry/Londonderry, and we survey and fit throughout that part of County Londonderry, including the BT49 district.

Do you need permission in Limavady?
Northern Ireland's householder permitted development allows rooflights within limits — no more than 15 cm projection on road-facing slopes and a 0.5 m margin from ridge, eaves and party walls. A side-facing window within 15 m of a neighbouring boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Technical Booklet F1 (2022) asks for replacement windows and rooflights in existing homes to reach WER Band C or a U-value of 1.6 W/m²K, assessed in the vertical position. Extensions follow a 25% glazing allowance in Technical Booklet F1.

- Agree the quote. You approve the specification and price before anything is ordered.

Questions about skylight installation in Limavady
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
Do you fit rooflights bought elsewhere?
Yes. We check the product and the opening first, and our workmanship terms cover the fitting rather than the product.
Do I need to be at home for the survey in Limavady?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Limavady?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
