Velux Installation in Romsey

Velux window installation in Romsey requires the correct approved flashing kit for the roof covering in place. The Welsh slate and clay tile on period town centre properties, concrete interlocking on suburban stock across Romsey's housing stock requires different flashing geometry for each product type. On concrete interlocking tile — the most common type in Romsey's estate housing — the flashing profile must match the tile profile precisely. An incorrectly specified flashing on any tile type will leak in its first wet winter. We use manufacturer-approved kits for all tile types.

Planning for Velux Windows in Romsey

Most single Velux installations in Romsey are permitted development — no planning permission required. Restrictions apply to front or principal elevation windows in conservation areas, windows projecting more than 150mm above the roof pitch, and any work on listed buildings. We advise on planning implications at the survey stage for all Romsey and SO51 properties before providing a quote.

Flat Roof Skylights for Romsey Extensions

Single-storey rear extensions in Romsey can be significantly improved by integrating a fixed-light or opening skylight into the flat roof. If your flat roof is being replaced at the same time, including a skylight in the programme is the most cost-effective approach — no separate return visit and the skylight can be seamlessly integrated into the new GRP or EPDM system. We quote for combined flat roof replacement and skylight installation across Romsey and all SO51.

Good to know

Disruption, Mess & Weather

One or two days with some cutting noise and internal making-good; we sheet the room below and clear up fully. You do not need to stay home for external work - we just need power and access agreed in advance.

Installation runs year-round; the opening is never left exposed overnight. Romsey sits in the Test valley, where river humidity slows drying and encourages moss on shaded slopes.
