Loft conversions in Llandudno present specific challenges: conservation area requirements, the coastal exposure of any new roof windows, and period roof construction that may need significant structural work.
From a roofing standpoint, Velux windows are significantly simpler and less expensive than dormers. A Velux installation requires a structural opening in the existing rafter, correct flashing installation, and redressing of surrounding tiles or slate. A dormer requires new structural work, significantly more waterproofing complexity, and usually planning permission in the Llandudno Conservation Area.
Key fact: Velux and equivalent roof windows require a flashing kit matched to the specific roof covering; an incorrect kit is the most common cause of roof-window leaks. Source: Velux installation specifications

Yes — Velux produces specific flashing kits for Welsh slate (the EDL system for natural slate). The installation requires careful slate cutting around the frame opening.
A single Velux window takes 3-5 hours. Two or three windows add 2-3 hours each. We typically complete all Velux work for a standard loft conversion in a single day's visit.
A loft conversion adds habitable space that the original roof structure was not designed for. Building control requires that the structural adequacy of the roof is assessed as part of any loft conversion application. From a roofing perspective, this typically involves sistering or replacing rafters where they are inadequate for the new loading, adding structural ridge beams where needed, and ensuring the new floor structure does not compromise the existing roof behaviour. We manage the roofing structural element of loft conversion projects in coordination with the main contractor and structural engineer.
Velux windows installed on exposed north and west-facing slopes in Llandudno face the most demanding weather conditions of any domestic roof window installation in North Wales. We specify the correct Velux window rating for the site's exposure zone and use the correct flashing kit for the roof covering — EDL for Penrhyn slate, EDW for profiled tile. Incorrect flashing specification is the cause of almost every leaking Velux window we repair. It costs nothing to specify correctly at installation.
