Local roof moss cleaning for homes around Northampton. Hand-scrape, soft-wash and biocide — no pressure washers near your tiles, ever. We cover Northampton and the wider the surrounding towns and villages. Roofs round here see high humidity and frequent rainfall that fuels moss, algae and lichen, and most of the properties we treat are built with clay plain tiles, concrete interlocking tiles and natural slate — so we tune the soft-wash mix and dwell time to whatever's on your ridge.
Most of the roofs we treat around Northampton are built with clay plain tiles, concrete interlocking tiles and natural slate. 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 Northampton 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 Northampton.
Professional biocide applied at low pressure. It kills moss, algae and lichen at the root and keeps working for months — important given the high humidity and frequent rainfall that fuels moss, algae and lichen.
Gutters cleared, downpipes flushed, debris bagged and taken away. Included on every Northampton 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: high humidity and frequent rainfall that fuels moss, algae and lichen. 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 Northampton, the combination of clay plain tiles, concrete interlocking tiles and natural slate and the surrounding towns and villages'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.
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.
Yes. We clean carefully around PV panels and mounting brackets and avoid running biocide over the cells.
After a full scrape, soft-wash and biocide treatment, most roofs in Northampton stay visibly clear for several years. An optional annual top-up biocide stretches that further.
Never. High-pressure water strips the protective coating off concrete tiles and forces water under slate. We hand-scrape and soft-wash only — that's the only safe way to clean a roof.
Most Northampton 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.
