Why Galway Properties Suffer with Moss
County Galway receives over 1,200mm of rain per year. Combine that with mild Atlantic winters that rarely go cold enough to kill moss naturally, and you have ideal growing conditions running from September straight through to June. North-facing roofs, shaded driveways and damp patios are often green from October to April.
The problem is more than cosmetic. On roofs, moss holds moisture against tile surfaces. In hard frosts - and Galway does get them - that moisture expands, cracking tiles and loosening pointing from ridge lines. On driveways and patios, wet moss is a serious slip hazard and the roots work into the joints of block paving, lifting them over time. Left untreated, moss damage is expensive to fix.
Our Moss Treatment Services in Galway
We treat moss on all exterior surfaces across the county, from the suburbs of Galway City to rural properties as far west as Connemara and south to Gort.
Roof Moss Treatment
Soft-wash biocidal application to slate, concrete and clay tile roofs. Kills moss and lichen at the root. Dead growth rinses away in rain over the following weeks.
Driveway Moss Treatment
Pre-treat with biocide followed by pressure washing to remove all growth. Re-sanding of block paving joints included where needed.
Patio Moss Treatment
Flagstone, sandstone, porcelain and concrete slabs. We remove moss without damaging surface finishes, restoring grip and colour.
Wall and Render Treatment
Algae and green staining on rendered walls, stone walls and painted surfaces treated with low-pressure soft wash. No damage to finishes.
Why Choose West Clean Property Care for Moss Treatment in Galway
We Treat the Cause, Not Just the Symptom
Scraping or pressure washing alone doesn't stop moss - it regrows within months. Our biocidal treatments kill the growth at the root and leave a residual protection layer.
Right Method for Every Surface
Pitched roofs, flat roofs, block paving, sandstone - they each need a different approach. We assess first and apply accordingly. We never use high pressure on roofs.

Moss Treatment Across County Galway
We cover the full county. Properties in Galway City - particularly the older terraced houses in Bohermore, Shantalla and the Claddagh - are frequent customers for roof and wall moss treatment. The coast at Salthill and Barna faces salt-laden air on top of the usual rain, which accelerates algae growth on rendered walls significantly.
Out in the county, we work regularly in Tuam, Headford, Athenry, Loughrea and Ballinasloe. Connemara properties face the harshest conditions - the combination of Atlantic exposure and limited drying time means moss grows faster here than almost anywhere else in Ireland. If you have a property west of Galway City, annual moss treatment is essential, not optional.
Our Moss Treatment Process
- 1 Assessment - We inspect the surface, identify moss and lichen type, and choose the correct biocidal product and application method.
- 2 Area preparation - We protect surrounding plants, gutters and drainage points before treatment begins.
- 3 Biocidal application - Treatment is applied at the correct dilution using either low-pressure spray or soft-wash equipment depending on the surface.
- 4 Optional physical removal - On driveways and patios, we follow up with pressure washing once the biocide has worked. On roofs, we allow rain to wash away dead growth naturally.
- 5 Final inspection and advice - We walk the area with you, confirm results, and advise on retreatment intervals for your specific surface and exposure.
