Velux windows and skylights are one of the most common sources of roof leaks in homes across County Meath. They bring light and ventilation into roof spaces, loft conversions, bathrooms and kitchens — but when the seals deteriorate, the flashing fails, or the unit itself is damaged, they let in water with remarkable efficiency.
The good news is that the majority of Velux and skylight problems do not require a full replacement. A correctly diagnosed and properly repaired roof window will give years of continued service. The key is identifying the actual source of the problem rather than applying a temporary sealant that masks the issue for one winter and fails the next.
Mr Clean Roofing carries out Velux and skylight repairs across County Meath every week. Patrick has extensive experience working with all types of roof windows — Velux centre-pivot, top-hung, flat roof units, and fixed skylights from other manufacturers. He knows where these windows fail, what causes it, and how to fix it properly.
We also install new Velux windows and skylights on existing roofs — bringing natural light into dark rooms, attic conversions and bathroom spaces across Meath.
Costs depend on what is causing the problem and what is needed to fix it. As a general guide:
Sealant and minor flashing repairs around a Velux window — prices start from €300 depending on access and the extent of the work.
Full lead flashing replacement around a roof window — prices start from €450 depending on the size of the unit and the complexity of the surrounding roof detail.
Sealed glass unit replacement (fogged glass between panes) — prices start from €350 depending on the size and specification of the unit.
Handle, hinge and mechanism repairs — prices start from €200 depending on the parts required.
New Velux window supply and installation on an existing pitched roof — prices start from €700 per window including the flashing kit, depending on the size and specification of the unit chosen.
The only accurate price for your specific window is one based on an inspection — which we carry out for free and with no obligation.
Not necessarily. The majority of Velux leaks are caused by failed flashing, deteriorated sealant, or cracked surrounding tiles rather than a fault with the window itself. In most cases a properly executed repair will restore the window to full working order at a fraction of the cost of replacement. We will inspect and give you an honest assessment.
A quality Velux window correctly installed and properly flashed will typically last 20 to 30 years before the unit itself needs to be considered for replacement. The flashing around it may need attention sooner — particularly in exposed or heavily weathered locations in County Meath.
Yes, in most cases. Where the sealed unit has failed — shown by fogging or condensation between the panes — the glass unit can be replaced independently of the frame. This is significantly cheaper than replacing the entire window and is the correct approach where the frame itself is in sound condition.
Yes. We install new Velux windows and skylights on existing pitched and flat roofs across County Meath. We assess the roof structure, position the window for best effect and correct drainage, and install with fully waterproof flashing to manufacturer specification.
Velux windows come in a standardised range of sizes referenced by codes such as CK04, MK06, FK08 and so on. The right size depends on the rafter spacing in your roof, the size of the room, and how much light you want to introduce. We will advise you on the best size during a free survey.

Do not leave a leaking skylight — water ingress from a roof window damages ceilings, insulation and roof timbers quickly and the repair bill grows the longer it is left. Call us for a free inspection and a written quote with no obligation.
