From a quick moss treatment to a full roof restoration, we look after roofs across Hounslow the careful way — tile-safe methods, long-lasting results and a written quote up front. We cover Hounslow and the wider the local area. Roofs round here see damp British winters that drive heavy moss build-up on roof slopes, 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 Hounslow 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 Hounslow 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 Hounslow.
Professional biocide applied at low pressure. It kills moss, algae and lichen at the root and keeps working for months — important given the damp British winters that drive heavy moss build-up on roof slopes.
Gutters cleared, downpipes flushed, debris bagged and taken away. Included on every Hounslow 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: damp British winters that drive heavy moss build-up on roof slopes. 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 Hounslow, the combination of clay plain tiles, concrete interlocking tiles and natural slate and the local area'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.
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.
Yes — we clear gutters, test downpipes and bag the debris on every Hounslow roof clean. It's included, not an upsell.
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.
Most Hounslow 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.
