Roof window installation in Wrexham covers mixed Victorian, inter-war and post-war properties where Welsh slate and concrete tile is the dominant covering. Welsh slate and clay tile roofs require specialist installation — hand-cutting rather than breaking the surrounding tiles to fit. We carry Velux's own flashing kits specified for each tile profile used on Wrexham properties.
Most Velux installations in Wrexham fall within permitted development rights and require no planning application. Conservation area properties in Wrexham require more careful assessment. We advise on consent requirements at the survey stage for all Wrexham addresses and will not proceed with any installation that requires consent without confirming it first.
Installing a Velux window on mixed Victorian, inter-war and post-war Wrexham properties with Welsh slate and concrete tile requires hand-cutting the surrounding tiles — not breaking them to fit. We use Velux's EDL flashing kit specified for Welsh slate and concrete tile profiles, creating a weathertight junction at the window perimeter. Where existing tiles are removed during installation, we source matching reclaimed Welsh slate and concrete tile for reinstatement. On conservation area Wrexham properties this matching is essential.
Roof windows that sit flush with the existing slope and do not project above the roof plane fall within permitted development rights on most Wrexham properties. Conservation area Wrexham properties require assessment — some Chester area conservation designations restrict roof alterations visible from the street. We confirm the planning position at the survey stage before any work is quoted.
The Velux GGL centre-pivot in sizes M04 to M06 is the most common installation on Wrexham properties. The GGU polyurethane model with enhanced weather resistance is recommended for north-facing Wrexham slopes where higher rainfall than Chester from proximity to the Clwydian Range creates elevated condensation risk. Both models are compatible with Welsh slate and concrete tile profiles. Electric operation, triple glazing and obscure glass are available at additional cost.

Roof windows bring light into a loft or top-floor room — here is when a Velux is the right move for a Chester property and when to wait.
When it is not the answer: If the roof is due for replacement soon, it is worth fitting the window as part of the re-roof rather than twice — we will advise on timing. Read the full guide.
We assess the roof structure and pitch and recommend the right size and glazing.
A fixed price covering the window, flashing kit and making-good.
Tiles or slates removed and rafters trimmed and reinforced correctly.

Roof-window work is done from scaffold or a tower for safe access and glazing handling. Scaffold is specified for: most roof-window installs - always itemised in your written quote, never a hidden extra, and we arrange it.
Wrexham has a broad Welsh town mix — Victorian terraces, stone period property, and extensive inter-war and post-war estate housing. Pavement scaffold and skip permits go through Wrexham County Borough Council; allow a few working days on streets like Hope Street, Regent Street, Rhosnesni Lane where space is tight.

A day or two of work with some internal dust where an opening is formed — we sheet the room and clear up thoroughly. You do not need to stay home for external work - we just need power and access agreed in advance.
We time the roof opening around dry weather and never leave it exposed overnight to Chester’s rain. Wrexham sits inland towards the Welsh hills, wetter than Chester with significant rainfall, and slate is the traditional covering across much of the older stock.
