Moss, lichen and algae growth on tiles and slates traps moisture against the roof surface, accelerating mortar erosion and eventually the tiles themselves. Our roof cleaning specialists use low-pressure soft washing combined with a professional biocide treatment throughout Ranelagh — far safer and more effective than high-pressure jet washing, which cracks tiles, displaces ridge mortar and forces water under the overlap. A professionally cleaned and biocide-treated roof in Ranelagh stays clear for significantly longer and reduces the frost damage risk that comes with moisture trapped in moss growth.

Ranelagh is a leafy and sought-after inner south Dublin suburb with excellent Luas Green Line access, characterised by Victorian and Edwardian terraced housing on tree-lined roads and a vibrant village centre. Properties in Ranelagh are predominantly Victorian terraces, large Edwardian semi-detached homes, 1920s and 1930s semis, and some modern apartment developments near the Luas stops. Common roof issues we address here include natural slate deterioration on Victorian and Edwardian properties, lead valley failures on large Edwardian rooflines, chimney repointing on terraced rows, flat roofs on rear extensions of divided houses, and guttering on mature tree-lined streets, making professional roofing maintenance essential for Ranelagh properties. Our roofers understand the construction methods and typical materials used in Ranelagh — every inspection is free and every job begins with a written quote.

Frequently Asked Questions

From €700 — most properties completed in half a day. Free inspection first, so you know exactly what's involved before agreeing to anything.
Soft washing is the correct method. High-pressure jet washing can crack and dislodge tiles, wash away ridge mortar bedding, and force water under the tile overlap — causing internal damp that may not appear for months. Our soft washing process uses low pressure combined with a professional biocide solution that kills moss, lichen and algae at the root, leaving a clean roof that stays clean for 3–5 years after treatment.
Yes. Moss retains water against the tile surface and mortar joints, accelerating frost damage, mortar erosion and tile cracking. Removing moss and applying a biocide treatment removes that moisture trap and significantly slows future deterioration. For concrete tile roofs in Ranelagh, regular cleaning every 4–6 years is a cost-effective maintenance strategy that delays the need for full roof replacement.
A standard semi-detached roof in Ranelagh typically takes half a day to a full day depending on pitch, size and the extent of moss growth. Treatment solution is applied after cleaning and continues to work for several months after the visit. There is no need for you to vacate the property and access is via roof ladder — we do not require scaffolding for most residential jobs in Ranelagh.
Yes. We frequently combine roof cleaning with repair work — replacing cracked or broken tiles, repointing ridge sections, clearing gutters and downpipes — on the same visit. This is the most cost-effective approach and avoids a second attendance fee. We will identify any repair work needed during our free assessment of your Ranelagh property and include it in the same written quote.
In Ranelagh, the roofing problems we see most often are natural slate deterioration on Victorian and Edwardian properties, lead valley failures on large Edwardian rooflines, chimney repointing on terraced rows, flat roofs on rear extensions of divided houses, and guttering on mature tree-lined streets. A free inspection is the best way to check whether any of these apply to your roof — call 085 782 8222 to arrange one.
