Roofs in Colchester take a beating from British weather. Our soft-wash specialists strip moss, algae and lichen back to clean tiles without high-pressure damage — and treat the surface so it stays clear. We cover Colchester and the wider the surrounding postcodes. Roofs round here see cool, wet shoulder seasons that suit moss colonisation on north-facing roofs, and most of the properties we treat are built with natural slate, Bridgwater pantiles and concrete tiles — so we tune the soft-wash mix and dwell time to whatever's on your ridge.
Most of the roofs we treat around Colchester are built with natural slate, Bridgwater pantiles and concrete tiles. Each tile type needs a slightly different approach — concrete tiles need a gentler biocide dwell time than slate, and pantiles need careful scraping in the lap. Here's what's included on a typical Colchester job:
Every tile cleared by hand from a roof ladder or scaffold tower — no pressure washers, no broken tiles. The right approach for the older roofs you see across Colchester.
Professional biocide applied at low pressure. It kills moss, algae and lichen at the root and keeps working for months — important given the cool, wet shoulder seasons that suit moss colonisation on north-facing roofs.
Gutters cleared, downpipes flushed, debris bagged and taken away. Included on every Colchester roof clean.
Photos of every slope, ridge and valley. You'll see exactly what's on your roof before we quote — no pressure.
We re-bed loose ridge tiles and flag failing pointing while we're up there. Small fixes done on the day; bigger ones quoted separately.
Optional annual top-up applied from the ground. Stretches results from "several years" to "indefinitely" with minimal cost.
The short answer: cool, wet shoulder seasons that suit moss colonisation on north-facing roofs. Moss spores are airborne almost year-round, and any roof slope that stays damp for long periods will start to colonise — usually on the north-facing pitch first, then under any overhanging trees.
Around Colchester, the combination of natural slate, Bridgwater pantiles and concrete tiles and the surrounding postcodes's climate means most roofs need attention every 3-5 years if they've never been treated, and far less often once a biocide programme is in place.
Left untreated, moss holds water against the tile surface, freezes and thaws through winter, lifts the lap, and eventually pushes debris into the gutter line. That's when small problems become roof-replacement problems.
No — all the work is carried out outside. Just tell us about parking, side-gate access, pets and any solar panels before we arrive.
Yes, as long as it's dry and safe to access. Autumn and winter are actually peak season for treating moss — the biocide goes on before spring growth kicks off.
Without a biocide treatment, yes — usually within 12-18 months. The biocide is what kills spores at the root and keeps the roof clear long after we leave.
Most Colchester jobs are priced from the ground after a free roof inspection — pitch, access and tile type matter far more than property size. You'll get a written, fixed-price quote with no obligation.
Yes. We use a professional, fully biodegradable biocide. We mask off planting where needed and flush gutters and downpipes once we're finished.
