Roof Cleaning in Mayo - Why It Can't Wait
Mayo's combination of high rainfall, Atlantic winds and mild winters creates the most demanding conditions for roof surfaces in Ireland. Roofs in Castlebar, Westport, Ballina and rural Mayo rarely fully dry from October to April. Moss thrives in that persistent damp without the severe frosts that would kill it. Coastal properties from Westport to Belmullet and Achill additionally accumulate lichen and salt deposits driven in by Atlantic spray - a combination that concrete and clay tiles were not designed to cope with year-on-year without maintenance.
The most expensive roof damage we encounter is always on properties where moss has been visible for years but nothing was done. At a certain point the root structure of heavy moss growth physically lifts tile edges. Once water is getting under tiles, the problem progresses from aesthetic to structural quickly. Professional cleaning and biocide treatment every few years is a small investment against that outcome.
What's Included in Our Mayo Roof Clean
Moss and Algae Removal
All moss, algae and lichen removed from the full roof surface. Low-pressure approach throughout - no tile damage.
Biocide Treatment
Applied after cleaning to kill spores and prevent regrowth. Biocide treatment extends the clean period to 2-3 years in Mayo's climate.
Ridge and Verge Check
We inspect ridge tiles and verge pointing during the clean. Any signs of loose mortar or cracking flagged to you.
Gutter Clear
Roof debris cleared from gutters as part of the clean. We don't leave freshly removed moss sitting in the gutterline.

Roof Cleaning Mayo - FAQs
Moss holds moisture against tiles year-round. In Mayo's climate, this causes freeze-thaw micro-cracking, loosens ridge and verge mortar, and heavier moss growth physically prises tile edges upward - allowing water ingress beneath the tile.
With a post-clean biocide treatment, most Mayo roofs stay clean for 2-3 years. Coastal properties may be at the lower end. Without biocide, moss regrows within 12-18 months.
Yes. We cover all of County Mayo including coastal areas. Coastal properties have additional lichen and salt deposit issues that we account for in our treatment approach.
