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 Coolock — 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 Coolock stays clear for significantly longer and reduces the frost damage risk that comes with moisture trapped in moss growth.

Coolock is a large northside Dublin suburb between Artane and Santry, with predominantly 1950s and 1960s corporation-built semi-detached and terraced housing stock, and large-scale 1970s and 1980s private estate developments. Properties in Coolock are predominantly 1950s and 1960s corporation-built semi-detached houses, 1970s and 1980s private estate housing, terraced housing in older parts, and some 1990s infill developments. Common roof issues we address here include natural slate deterioration on 1950s and 1960s properties, concrete tile cracking and ridge tile repointing on 1970s and 1980s estates, flat roofs failing on garage and rear extension roofs, fascia and soffit replacement on ageing housing stock, making professional roofing maintenance essential for Coolock properties. Our roofers understand the construction methods and typical materials used in Coolock — 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 Coolock, 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 Coolock 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 Coolock.
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 Coolock property and include it in the same written quote.
In Coolock, the roofing problems we see most often are natural slate deterioration on 1950s and 1960s properties, concrete tile cracking and ridge tile repointing on 1970s and 1980s estates, flat roofs failing on garage and rear extension roofs, fascia and soffit replacement on ageing housing stock. A free inspection is the best way to check whether any of these apply to your roof — call 085 782 8222 to arrange one.
