Is your roof covered in unsightly dark green moss, black algae streaks, or white lichen spots? Galway’s wet climate creates the perfect breeding ground for organic growth on tiled and slate roofs.
While heavy moss ruins your home’s curb appeal, the real danger lies underneath the surface. Moss acts like a giant sponge, retaining water against your tiles during heavy rainfall. In winter, this trapped water freezes, expands, and cracks your roof tiles, leading to costly leaks.
At Shamrock Roofing & Guttering, Desmond Sweeney provides professional, safe roof cleaning and biocide soft washing services across Galway.
We never use harsh, destructive high-pressure blasting that strips tile coatings or forces water under your roof membrane. Our controlled cleaning process removes moss safely and protects your roof for years to come.
When comparing roof cleaning methods, high-pressure power washing presents significant risks by potentially stripping protective sand or color coatings from your tiles, forcing water under the felt layer, and leaving spore roots intact so moss quickly returns within one to two years.
In contrast, soft washing offers a completely safe alternative that preserves your tiles' factory finish through a low-pressure application with zero risk of water ingress.
By utilizing a specialized biocide treatment that penetrates deep to kill microscopic roots entirely, soft washing prevents rapid organic regrowth and delivers up to five years of long-lasting, clean protection.
We specialise in residential and commercial roofing across Galway, offering everything from urgent repairs to full roof overhauls. We are your local Galway Roofers available 24/7.
