Roof Cleaning in Merton

A Merton roof out toward Mitcham and Morden keeps its moss quietly until a whole slope has greened. A grey-green film settles over the tile, dark streaks run down from the ridge, and moss gathers in the gutters where the common and greenside trees hang over the eaves. A season or two beneath that growing shade usually beds it in before it stands out from the road. Left to it, the trapped damp works into the laps that keep a roof tight, loosening the tile clips and fixings as it goes.

On the eastern side of the borough, Mitcham and Morden spread around the open ground of Mitcham Common and the low valley of the River Wandle. The interwar semis of the 1920s and 1930s here wear clay and concrete tile on their gabled pitches, set among mature front gardens and tree-lined roads, with older Mitcham cottages closer to the greens. Damp off the common and the Wandle, the low-lying ground, and the growing shade of the estate trees keep many north-facing slopes from drying between one wet spell and the next. Mitcham Common and the Wandle keep these low streets damp well past the rain.

We keep off the tiles from first to last, whether clay or concrete. We draw moss, algae and lichen off each slope from raised towers or from ground level with specialist equipment, so no tile bears our weight. For over 15 years Ben's Roof Cleaning has delivered dependable roof cleaning in Merton this way, opening each job with a patch test and a risk assessment and finishing with a non-toxic biocide to hold the regrowth the damp keeps feeding.

Low-lying ground holds the wet against the slopes for long spells. The commons and the greens keep the eastern streets shaded through the day.

That combination of interwar tile, low damp ground and the open commons is what lets moss build on a roof here. It greens the north-facing slopes long before the open, sunnier ones show anything at all. Roofs on the low ground by the common carry the damp the longest.

Cleaning a shaded suburban roof well starts with reading it rather than blasting it. The tile, the pitch and the depth of growth all decide how a Merton roof should be handled, so a patch test and a close inspection always come before any cleaning. Getting that judgement right is what protects the covering underneath.

Method then matters far more than force on interwar tile. Growth is drawn off gently with specialist equipment instead of scraped or stood on, so clay and concrete tile keep their surface and nothing cracks underfoot. The gutters and downpipes are cleared in the same visit, since loosened moss and leaf debris wash straight off the slope into them.

Finishing the job properly is what makes it last. With the roof clear, a non-toxic biocide is worked across the slopes to slow the return of moss and algae in the damp air off the common. A closing inspection then checks the tiles, the flashing and the roofline before the site is left tidy.
