Salt air at Fortrose accelerates the aluminium components in standard Velux flashing kits. We specify the lead collar option where available and apply protective sealant to aluminium components on all Firth-facing Fortrose installations.
The two most common Velux failures present identically — water visible at or below the frame — but have completely different causes and fixes. Flashing collar failure means water is entering from outside the window via the junction between the frame and the surrounding tiles. Glass seal failure means the hermetic seal on the double-glazed unit has broken. In Highland conditions, flashing collar failure is by far the more common. We diagnose the actual fault at survey before quoting any repair — fitting a new glass unit on a leaking flashing collar wastes money and does not fix the leak.
Velux flashing systems have a design life of 20–25 years in normal UK conditions. In Highland, we see first failures at 15–20 years — the wide annual temperature differential between summer roof surface heat and Highland winter frost accelerates the thermal cycling that gradually lifts the flashing collar from the tile course above it. Properties at elevated locations — Culloden, Westhill, Grantown-on-Spey — show earlier failure than valley-floor properties because the temperature swing is more extreme. We carry the most common EDW flashing kit sizes for same-day repair on most Fortrose properties.
Condensation on the window interior surface — particularly in early mornings in cold Highland weather — is a ventilation problem, not a flashing problem. The Velux glass is the coldest surface in the room and condensation from inadequate roof space ventilation deposits there. Fitting a new flashing on a condensation problem costs money and does not solve the issue. We assess ventilation cross-flow as part of every Velux survey and flag this where it is the actual cause — roof space ventilation improvement is the correct fix, and it is usually straightforward and low cost.

Velux flashing systems have a design life of 20–25 years in typical UK conditions. In Fortrose, where salt spray from the open Firth accelerates metal corrosion significantly, we see first failures at 15–20 years — approximately 20–25% earlier than the design life. The thermal differential between a Highland summer roof surface (50°C+) and a winter frost (-10°C to -15°C) subjects the flashing collar to 60°C+ annual cycling. Over 15–20 years this gradually lifts the collar from the tile course above and separates it from the window frame junction. Once lifted even slightly, Highland-driven rain tracks underneath and enters the roof space.
The most common misdiagnosis on a Fortrose Velux leak is patching the visible gap with silicone rather than replacing the flashing collar. Silicone on a failed flashing holds for one to two Highland winters before the thermal cycling cracks or separates it. We carry standard EDW flashing kit sizes for the most common Velux models and can replace the full collar assembly — not just seal over the failure point — on a same-day survey visit in most cases. The correct repair carries our 10-year workmanship guarantee and does not require revisiting at the same location within the guarantee period.
We cover the full range of Velux and skylight work for Fortrose properties: flashing collar replacement, glass unit replacement on failed double-glazed units, operating mechanism repair on opening windows, and condensation diagnosis where the issue is ventilation rather than a leak. For Fortrose properties with flat rooflights — the polycarbonate dome type common on 1980s–90s extensions — we carry out full upstand replacement in EPDM, which handles the Highland frost cycling significantly better than the original installation in most cases.

Call 01463 262835"1997 Velux had been patched three times. New flashing collar — completely dry ever since. Should have replaced the collar from the first patch."
"Correctly diagnosed as condensation, not a leak. Roof ventilation improved. Problem gone. Previous roofer had fitted a new flashing that made no difference."
"Two Velux on the rear pitch. Both had failing flashings after 18 years — the plateau temperature swings are severe. Both done in one day. Clean, dry, guaranteed."
We cover all Highland towns and a 25-mile radius from Inverness.
Leaking: water appears during or after rain, typically at the frame edges or from above. Condensing: water appears in cold dry weather — often early morning frost conditions — regardless of rainfall. If your Velux runs water on a dry frosty morning, condensation from inadequate roof ventilation is the likely cause. We diagnose the difference at survey before quoting.
Standard size flashing collar replacement costs £200–£450 depending on window size and roof pitch. We carry common EDW kit sizes for same-day repair on most {town} properties. Free assessment — call 01463 262835.
In most cases, repair is the right answer. The glass unit and frame rarely need replacing. The flashing collar — the element that fails in Highland thermal cycling — is replaced as a kit while the window itself remains in place. Only when the frame has suffered prolonged water damage and has structurally deteriorated does full window replacement make sense.
15–20 years in Highland conditions — shorter than the 20–25 year UK average due to the wider annual temperature differential. Properties at higher elevation show earlier failure. We specify the correct EDW flashing kit for the roof pitch and tile profile, which maximises the service life for Highland conditions.
Yes — new Velux installation including structural roof trimming, correct flashing kit for the pitch and tile profile, and connection to the existing roofing membrane. Supply and fit for a standard GGL window starts at approximately £600. Free survey to confirm structural suitability and quote. Call 01463 262835.
The drainage channels at the base of the outer Velux frame can accumulate pine needle and birch seed debris in Highland locations with significant tree cover. If these block, water overflows into the frame rather than draining away. Clear with a small brush annually in October. This is a simple maintenance step that prevents what can look like a flashing failure.
In most cases, no — Velux installation on the rear roof slope is permitted development. Front elevation skylights on conservation area properties, or on listed buildings, may require consent. We confirm planning requirements at survey and flag any consent needed before the project is agreed.
No call-out fee. No obligation. Honest survey from a local Highland roofer.
