Mount Merrion homeowners trust Peak Roofing for roof cleaning. 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 Mount Merrion — 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 Mount Merrion stays clear for significantly longer and reduces the frost damage risk that comes with moisture trapped in moss growth. Free assessment, written quote, no call-out charge.

Mount Merrion is a carefully planned residential suburb developed primarily in the 1940s and 1950s on elevated ground south of UCD, with well-maintained homes on generous plots and mature tree-lined avenues. Properties in Mount Merrion are predominantly 1940s and 1950s semi-detached and detached houses, bungalows, and some larger detached homes on wide leafy roads. Common roof issues we address here include ageing felt underlays now exceeding 70 years on original 1940s and 1950s properties, chimney repointing on mid-century stock, concrete tile replacement on later 1960s homes, and guttering blockages from mature avenue trees, making professional roofing maintenance essential for Mount Merrion properties. Our roofers understand the construction methods and typical materials used in Mount Merrion — 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 Mount Merrion, 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 Mount Merrion 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 Mount Merrion.
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 Mount Merrion property and include it in the same written quote.
In Mount Merrion, the roofing problems we see most often are ageing felt underlays now exceeding 70 years on original 1940s and 1950s properties, chimney repointing on mid-century stock, concrete tile replacement on later 1960s homes, and guttering blockages from mature avenue trees. A free inspection is the best way to check whether any of these apply to your roof — call 085 782 8222 to arrange one.
