A leaking or failing skylight is one of those problems that tends to get worse faster than homeowners expect. What starts as a small drip during heavy rain becomes a persistent leak, then a damp patch on the ceiling below, then damaged plasterboard, stained insulation and — in a loft conversion — costly remediation to plastered walls and timber framing. In Tipperary's climate, where cold winters create significant condensation risk and rainfall is a year-round feature of life across the county, a skylight that is not performing correctly is a problem worth addressing promptly.
At Doherty Roofing, we carry out professional skylight repairs for homeowners across County Tipperary. From leaking Velux windows and failed flashing to fogged glazing units and stiff mechanisms, Jim and his team diagnose skylight problems accurately and carry out lasting repairs — not surface fixes that fail at the next downpour.

Here are the warning signs that should prompt you to contact Doherty Roofing for a free skylight inspection:
If you have noticed any of these signs, do not delay in arranging an inspection. Skylight problems rarely improve on their own — and the secondary damage caused by ongoing water ingress escalates quickly.
Velux is the dominant skylight brand on Tipperary's housing stock — the vast majority of roof windows installed on Tipperary properties from the 1980s onwards are Velux units. Many of these older Velux skylights are now reaching the point where seals have degraded, flashings have lifted and glazing units are failing — and while Velux is a well-engineered product, age and Tipperary's temperature cycling take their toll on every skylight brand eventually.
Fakro is the second most common brand we encounter on Tipperary properties — increasingly specified on newer builds and renovation projects throughout the county. We carry out repair and replacement work on both Velux and Fakro skylights, as well as other branded and unbranded systems found on older properties throughout Tipperary.
Why does my Tipperary skylight seem to leak more in winter than in summer?
Two factors specific to Tipperary's winter conditions contribute to this. First, winter rainfall is typically more wind-driven than summer rainfall — and wind-driven rain is much more effective at exploiting minor flashing and seal failures than vertical rain. Second, the temperature differential between warm internal air and cold winter external temperatures creates condensation on the glass that can be mistaken for a leak. Jim will determine which is causing your specific problem during the free inspection.
My skylight glass is foggy between the panes — is this fixable?
Not by cleaning — but yes, it is fixable. Persistent fogging between the panes means the sealed unit has failed and moisture has permanently entered the space between the glass layers. The glazing unit needs to be replaced. In most cases the frame can be retained and only the glass unit replaced, making this a relatively straightforward repair. We supply replacement units for all common Velux and Fakro skylight types.
Can a leaking skylight be repaired or does it need to be replaced?
In most cases a leaking skylight can be repaired effectively without full replacement — through flashing work, seal replacement or glazing unit replacement. Full replacement is generally warranted where the frame has deteriorated extensively, where the skylight is very old and multiple elements are failing simultaneously, or where the cost of repair approaches the cost of a new unit. Jim will give you an honest assessment of which is right for your specific situation.
Do you repair Velux skylights across all of Tipperary?
Yes. Velux is the most common skylight brand we work on across Tipperary. We carry out all types of Velux skylight repair — flashing repairs, seal replacement, glazing unit replacement and mechanism servicing — across all of County Tipperary from our Limerick base. We also work on Fakro and other roof window brands.
Skylight Leak Repairs
Systematic inspection of the frame, glazing seals, drainage channels and surrounding flashing before any repair is agreed. We locate the true source of water ingress rather than patching the most visible symptom.
Flashing Repairs and Replacement
The flashing between a skylight frame and the surrounding roof covering is one of the most common failure points — particularly on older Tipperary properties where the original flashing has been in place for fifteen or more years. We carry out full flashing repairs and replacements to restore a completely watertight seal.
Seal and Gasket Replacement
Hardened, cracked or deteriorated frame seals restored with new rubber gaskets — eliminating cold air infiltration and water penetration around the frame perimeter.
Glazing Unit Replacement
Replacement of failed sealed glazing units on all common Velux and Fakro skylight types. Frame retained where structurally sound.
Mechanism Repairs
Replacement of worn hinges, handles, stays and locks on opening skylights — restoring smooth, reliable operation and ensuring the skylight closes fully and securely.
Full Skylight Replacement
Where a skylight has reached the end of its serviceable life through age, extensive frame deterioration or repeated failures, we supply and install replacement skylights correctly flashed and sealed into the existing roof opening.
