Why Roof Cleaning Matters in Inverclyde
Inverclyde's damp West Coast climate creates the perfect conditions for moss, lichen and algae to thrive on roof tiles. Left untreated, this growth doesn't just look bad — it causes real structural damage that leads to expensive repair bills.
At On The Spot we use a safe hand-scraping method combined with professional biocide treatment — never high-pressure washing, which risks cracking tiles and flooding your loft. Our approach removes growth completely and protects against regrowth for years.
The Real Cost of an Untreated Roof
Blocked Gutters
Moss absorbs water, becomes heavy and slides into gutters causing blockages, overflows and rotten fascia boards.
Freeze-Thaw Damage
Moss roots grow into tile cracks. In winter, water freezes and expands inside these cracks — splitting and weakening tiles over time.
Heat Loss
A moss-covered roof acts like a wet blanket, drawing heat from your attic and increasing your energy bills year-round.
Reduced Kerb Appeal
A green or black moss-covered roof significantly affects your home's appearance and market value — especially for buyers and valuers.
Our Roof Cleaning Process
Free Roof Assessment
We assess the roof in person or via our drone survey to identify the extent of moss and lichen growth and agree the best approach before any work begins.
Safe Access Setup
Using IPAF-certified cherry pickers or access towers, we set up safely without walking on your tiles — protecting both the roof and our team.
Hand Scraping
All moss and lichen is carefully removed by hand scraping — never with high-pressure water which can crack tiles, dislodge pointing and flood your loft.
Biocide Treatment
A professional-grade biocide is applied to kill remaining microscopic spores deep in the tile — preventing regrowth for years, not just weeks.
Full Site Tidy
We block downpipes before work, clear all debris, rinse windows and leave your property tidier than we found it. Before and after photos provided.
