Peak Roofing and Building carries out professional roof cleaning and moss removal throughout Griffith Avenue. Over time, moss, lichen and algae growth on tiles and slates retains moisture against the roof surface, accelerating deterioration of the bedding mortar and eventually the tiles themselves. Our roof cleaning process uses low-pressure soft washing combined with a long-life biocide treatment — a far safer and more effective method than high-pressure jet washing, which can crack and dislodge tiles and wash away the mortar bedding protecting your ridge line. A properly cleaned and treated roof in Griffith Avenue stays clean for significantly longer and reduces the risk of tile damage caused by frost acting on moisture retained in moss growth.

Properties in Griffith Avenue are predominantly 1920s and 1930s large semi-detached and detached houses with Georgian Revival styling, some Edwardian detached on side streets. Common roof issues we address here include natural and concrete tile slippage on large pitched roofs, chimney stack repointing on multiple stacks, lead valley and hip flashing failure, moss growth on mature canopy-shaded pitches, valley gutter replacement. Our roofers understand the construction methods and typical materials used in Griffith Avenue — every inspection is free and every job begins with a written quote.

Frequently Asked Questions

Roof cleaning in Griffith Avenue is priced based on roof area, pitch and the extent of moss and lichen growth. As a guide, a standard 3-bed semi-detached typically costs €400–€900 for a full soft wash and biocide treatment. We carry out free assessments across Griffith Avenue and provide written quotes before any work is agreed.
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 Griffith Avenue, 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 Griffith Avenue 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 Griffith Avenue.
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 Griffith Avenue property and include it in the same written quote.
