Rain
Rain and moss in Donegal
Donegal town is the wettest of the three Donegal towns here at 1,525 mm a year, and Buncrana the driest at 1,292 mm (Met Éireann). Letterkenny ranks 3rd wettest of the 26 county towns on this site, with 429 mm from December to February alone.
Average rain a year, 1991–2020: our mean of Met Éireann's 1 km grid within 3 km of each town.
On a roof this wet, moss and algae come back faster. WestClean, working in the west, says moss can return within 6 to 9 months without a post-clean biocide. Ask for the treatment.
Donegal in numbers
Houses and roofs in Donegal
The BER area is the area insulated, not the slope: a pitched roof's slope is larger, so a real roof is often bigger than this. Donegal has 58,997 households in a house. Older roofs mean older, more porous concrete tiles and more slate, the roofs that need the gentlest clean.
The largest towns, Census 2022 (CSO): Letterkenny (22,549), Buncrana (6,971), Ballybofey (5,406), Carndonagh (2,768), Donegal (2,749).

What a soft wash costs for your roof
One tap: roughly how big the roof is. The answer is a published Irish soft wash rate times your area.
Published soft wash rate × your roof area
€1,080 to €2,520
90 m² at RoofQuote.ie's published €12 to €28 a m² for soft wash roof cleaning (VAT not stated). Our multiplication, not a quote. WestClean, a Tuam company, publishes €300 to €450 for a soft wash on a roof this size (small semi-detached, 70 to 90 m²). The sources are far apart.
- A biocide treatment on top is published at €4 to €10 a m² extra (RoofQuote.ie), or €150 to €400 as an add-on (HP Roofing).
- Gutter clearing is €80 to €200, often bundled (HP Roofing).
- Cleaning a house is at the reduced VAT rate, 13.5% (Revenue). Ask whether the price includes it.
How this is worked out
The roof area you pick, times RoofQuote.ie's published soft wash rate a m². Where WestClean publishes a price for that size of roof, it's shown too. The multiplication is ours. Rates read on 3 November 2026. The roof area is the slope, not the floor: a two-storey semi's roof is often 70 to 90 m². Moss thickness, pitch, height and access move the price. It's an estimate, never a quote.
