Why Moss is Silently Destroying Your Roof
In the damp, grey UK climate, roofs are the perfect breeding ground for moss, algae, and lichen. While a bit of green might seem harmless, moss is a highly destructive organism for roofing materials. It absorbs vast amounts of water, adding thousands of kilograms of dead weight to your roof structure over time.
During winter, this absorbed water freezes and expands. This process, known as freeze-thaw weathering, cracks roof tiles, degrades mortar on the ridge lines, and lifts slates. Furthermore, as clumps of moss inevitably roll down the roof during heavy rain or wind, they completely choke your gutters and downpipes, leading to water overflowing down your walls and causing expensive penetrating damp inside your home.
The Safe Removal Method: Scraping
Many cowboy cleaners will aggressively pressure wash a roof. This is a massive error that strips the granular protective layer off your concrete or clay tiles, vastly reducing their lifespan, voiding manufacturer warranties, and forcing water underneath the tiles and into the loft.
At GTM Insulation + Maintenance, we strictly use manual scraping and soft-washing. Utilizing custom-profiled tools that match the exact shape of your specific tiles, we gently but effectively scrape away the bulky moss. This method poses absolutely zero risk to your roof's structural integrity.
The Biocide Soft-Wash Treatment
Scraping removes the visible problem, but the microscopic root systems and spores remain. We ensure the moss doesn't immediately grow back.
Chemical Wash
Once the roof is scraped and gutters cleared, we apply a high-grade, HSE-approved biocide wash across the entire surface.
Root Destruction
The biocide penetrates deep into the porous tiles, actively killing all remaining algae, lichen, and invisible moss spores upon contact.
Self-Cleaning
Over the next 6-12 months, the weather cycles will naturally wash the dead microscopic organisms away, leaving your roof looking brand new.
