Moss and Algae in Roscommon - The Real Cause
County Roscommon sits in Ireland's midlands, but "inland" doesn't mean dry. The county's annual rainfall sits around 900mm, and properties near Lough Ree, Lough Key and the River Shannon experience almost constant ambient moisture that keeps north-facing surfaces damp for most of the year. Boyle, near the lakes in the northwest of the county, is one of the worst affected towns we service.
The other factor is shade. Many of Roscommon's older housing stock - particularly in the county town and in Ballaghaderreen - has mature trees close to the property. Shaded roofs dry out slowly and moss colonises them within a season if not treated. On driveways, the same logic applies: any paving with a tree overhead or that faces north will go green by October.
Moss Treatment Services Across County Roscommon
Roof Moss Treatment
Biocidal soft-wash treatment for concrete, slate and clay tiles. We don't pressure wash roof tiles - we treat them correctly at low pressure and let the biocide do its work.
Driveway Moss Removal
Block paving, tarmac and concrete driveways across the county. Biocidal pre-treatment followed by professional pressure washing to remove all growth.
Patio Cleaning and Treatment
Outdoor paving - flagstone, sandstone, porcelain and concrete slabs. We restore colour, grip and appearance ahead of spring and summer use.
Wall and Render Algae
Green and black algae staining on rendered and pebbledash walls. Soft wash application - safe for all external render types.
