Roof Cleaning in Barnsley Roofs that stand up to the hills.

Moss and lichen colonise a roof wherever moisture lingers and sunlight is scarce. This corner of the borough supplies both: the climate on the edge of the Pennines is cool and damp, north-facing slopes lose the winter sun early, and plenty of roofs are overshadowed by trees, houses on higher ground or the next row of terraces. Once a tile has the thinnest film of dust and spores on it, growth begins, and it spreads along the courses that stay wet longest.

Concrete tiles, which cover so many of the post-war estates, are porous and roughen as they age, giving moss something to hold. Older clay and slate hold less, but suffer in the same shady spots. Lichen, the flat crust that looks like paint spatter, prefers exposed, clean-air sites, and algae shows up as dark streaks below the ridge. A single roof can carry all three.

The roof shapes of these old mining places tell you how they grew. Colliery terraces in Hoyland and Wombwell run in long, shared lines, often in slate or tile. The council and private estates that followed are mostly concrete tile, in plain pitches that repeat down a street. Bungalows and extensions have shallow roofs that dry slowly, and newer homes on the edges have modern concrete tiles on low pitches.

Older buildings are different. Hoyland's parish church of 1830 is sandstone under slate, and similar materials appear in older houses and cottages in Elsecar, Tankersley and the old centres of the towns. Roofs like these need a lighter touch, and we assess each before agreeing to scrape it. If we think a roof is too fragile, we say so at the quote and suggest the right person to ask.

Tankersley is a small village on high ground west of the M1, with fields and plantations around it and the old church of St Peter at its heart. Its roofs stand open to the weather from every side, which suits lichen on older tile and keeps moss on the north slopes, and the trees that edge the village drop leaves into valleys and behind chimneys.

Birdwell runs along the A61 below, with terraces and semis facing the road and estates behind. After the Second World War, land at the north of the village was opened up for surface mining and later restored to pasture, and small woods remain around it. Roofs nearest the trees stay shaded and damp, and those beside the main road gather a dark film that moss grows into readily.

Hoyland stands on high ground, with Lowe Stand, an 18th-century folly, marking the highest point in the area. Roofs here are on exposed sites, and wind and rain strike them from the south-west. The estates are full of concrete tile in repeated runs, where moss forms along the bottom courses and around chimneys, and the commons, Hoyland Common and Platts Common, grew from early miners' and nail-makers' housing into streets of mixed ages.

Because the plots are open, wind carries spores from roof to roof, so a clean roof next to a green one is often recolonised within a few seasons unless the biocide has done its work properly. Newer building at Hoyland North adds more roofs of the same type, and moss that falls loose from any of them ends up in the gutters below.

Planned in the 1790s around the Fitzwilliam ironworks and pits, Elsecar still has its cottage rows, its green and its old workshops, and few villages in the region are better preserved. Roofs sit low and close, and the valley floor keeps them damp, so moss gets going early. A fair share of the buildings are listed, and much of the village is a conservation area.

Roofing work here calls for restraint. We deal only with the roof you have asked about, keep well clear of the neighbours' property and agree to scrape only where we are satisfied the roof will take it. Owners of listed homes may wish to raise the work with the council first. Gentle hand scraping and biocide sit at the lighter end of what could be done to a roof.

Wombwell is the biggest place we cover around Barnsley, with terraced streets near the High Street and the Old Town Hall, large post-war estates and newer developments on the edge of town. Many roofs are concrete tile on long, plain pitches, and a whole row tends to green up together on its shaded side, with moss gathering thickest at the eaves and around stacks.

The town sits in the Dearne valley, where damp air keeps roofs slow to dry, and bungalows and extension roofs in the shelter of fences and the main house are often the worst. On the newer estates, shallow pitches shed rain slowly, so algae streaks show early. Wherever a roof shares its line with a neighbour, we agree exactly which part is yours.

A roof that sees plenty of daylight and wind dries fast, and moss struggles on a dry tile. The easiest improvements come from letting light and air reach the slope: cutting back branches that overhang the roof, clearing leaves from valleys and keeping gutters flowing so that water leaves the roof edge instead of backing up beneath the tiles.

None of that is our work, and cleaning does not depend on it, but it makes a real difference to how long a treated roof stays bright. Where we see a specific cause of heavy growth, such as a branch that shades half a slope, we point it out so you can decide whether to deal with it.

Hilltop streets and sloping plots decide how we reach a roof. A level drive and a front garden make ladder placement simple. A road that climbs, a garden that falls away or a terrace with no space at the back need more thought, and we work out where a ladder can stand before we agree a date.

Wind is the other factor. Gusts on exposed sites such as Hoyland and Tankersley can make roof work unsafe even when the sky is clear, so we watch the forecast and rebook if the conditions are wrong. A roof we judge unsafe to work on is one we decline, and we explain why at the quote.

Each job starts with an agreement on what is included: the main slopes, any extension or garage roofs and whether you want the gutters cleared too. We then remove the moss and lichen by hand, section by section, sweeping the debris off the roof and out of the gutters as we go, and clearing the ground below.

When the surface is bare, biocide is applied over the whole roof. It deals with spores and the thin growth a scraper cannot lift. Across the weeks that follow, what is left withers and the rain carries it off. We cover plants and cars where we can, tidy up as we finish, and tell you about anything we noticed, such as slipped, cracked or porous tiles, or crumbling mortar at the verges.

Growth surges from autumn to spring, when roofs are wet and cold, and eases in the drier months. May to July is the best slot for a clean, because a dry roof is safe to work on and the biocide gets a spell of settled weather. October suits roofs beneath trees, once most of the leaves are down.

Frost and gales rule out winter visits, particularly on the open Hoyland sites. A yearly glance from the pavement each spring is enough to judge: green on the north slope, dark patches by the gutter or moss in the channel all say it is time.

These crop up most often from Tankersley to Wombwell:

The moss from a roof ends up in the gutters, so gutter cleaning in Barnsley is the obvious companion. Soffit and fascia cleaning then refreshes the boards, and solar panel cleaning clears panels on the slope.
