From a quick moss treatment to a full roof restoration, we look after roofs across Dawlish Warren the careful way — tile-safe methods, long-lasting results and a written quote up front. We cover Dawlish Warren and the wider the wider region. Roofs round here see long shaded autumns and wet winters that keep tiles permanently damp, and most of the properties we treat are built with Welsh slate, Marley Modern concrete and traditional clay pantiles — so we tune the soft-wash mix and dwell time to whatever's on your ridge.
Most of the roofs we treat around Dawlish Warren are built with Welsh slate, Marley Modern concrete and traditional clay pantiles. 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 Dawlish Warren 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 Dawlish Warren.
Professional biocide applied at low pressure. It kills moss, algae and lichen at the root and keeps working for months — important given the long shaded autumns and wet winters that keep tiles permanently damp.
Gutters cleared, downpipes flushed, debris bagged and taken away. Included on every Dawlish Warren 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: long shaded autumns and wet winters that keep tiles permanently damp. 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 Dawlish Warren, the combination of Welsh slate, Marley Modern concrete and traditional clay pantiles and the wider region'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. We clean carefully around PV panels and mounting brackets and avoid running biocide over the cells.
Yes — we clear gutters, test downpipes and bag the debris on every Dawlish Warren 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.
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.
Yes. We use a professional, fully biodegradable biocide. We mask off planting where needed and flush gutters and downpipes once we're finished.
