Coleford roofs, specifically

Why roof moss grows so well on high ground in the west Forest.

Coleford is the main town on the western side of the Forest of Dean, sitting up on the plateau between the Forest's woodland and the Wye Valley, a few miles from the Welsh border at Monmouth. That position matters for roofs. Weather coming in from the west reaches Coleford before it reaches the Severn Vale, the town is higher and wetter than Gloucester, and there are trees on almost every side. A roof here spends a lot of the year damp, and moss, lichen and the black streaks of gloeocapsa algae thrive on damp.

The ground around the town adds to it. To the west the land drops steeply towards Newland and Redbrook on the Wye, and the houses down there sit in deep, shaded ground where mist hangs on into the morning. To the south and east, villages like Milkwall, Sling and Coalway run right up to the Forest itself, so many back gardens end at a line of oaks and conifers. North-facing pitches and roofs overhung by trees are always the worst: by the time someone rings us, the moss is often packed thick between the slates and has started filling the gutters.

Coleford's older houses are built from the stone underneath them. The Forest's grey and brown sandstone and the paler limestone around the edge of the coalfield both turn up in the walls of the cottages in the town centre and in the villages, mostly roofed in Welsh slate, with clay tile on some cottages and outbuildings. Many of the small stone cottages in places like Berry Hill, Christchurch and Broadwell started life as cottages put up on the edge of the Forest by miners and quarrymen, so they are often old, low and irregular, with roofs that have been patched over the years.

Around them is a lot of 20th-century housing: post-war estates, plenty of bungalows and dormer bungalows across the villages, and newer homes on the edges of the town. Those are mostly concrete interlocking tile, whose rough surface holds on to spores, so they green up quickly here too. The right method is different for each type of roof, which is why we survey first rather than quoting one price over the phone.

What we clean in Coleford

The roofs we see most around Coleford.

Four common types, and each gets a different method.

Welsh slate on stone cottages and town houses

The usual roof on Coleford's older stone buildings, from the town centre streets to the cottages scattered through the villages. Old slate gets brittle and the laps hold moss and damp. These get a manual dry moss scrape from a roof ladder hooked over the ridge, then biocide. No jet washing, and extra care around ridges, valleys and any old lead flashings.

Clay tile on cottages and outbuildings

Found on some older cottages, barns and outbuildings, especially in the villages such as Clearwell and Newland. Old clay goes soft and crumbly when it has been wet for years. We scrape it by hand only and treat it with biocide, working carefully around the hips and ridges where tiles are most likely to have slipped.

Concrete tile on post-war and newer estates

Most of the 20th-century housing in and around Coleford, including estates in Broadwell, Coalway and Five Acres. Concrete tile is tougher, but its rough surface holds a lot of moss. Thick moss comes off by hand first, then the roof gets a low-pressure clean if it needs one, then biocide. The colour keeps improving for a few weeks as the treatment works.

Bungalows and dormer bungalows

Common across the villages around Coleford. Lower roofs are easier to reach, but they often sit closest to trees and hedges, so they stay shaded and damp and collect more debris. Dormer cheeks and the valleys around dormers trap moss and need clearing by hand before the biocide goes on.

Where we work around Coleford

Roof moss removal across Coleford and the west Forest villages.

The town and the villages around it have different housing, but the same damp, wooded setting.

Town centre & Market Place

The old centre around the clock tower, with stone shops and houses, many roofed in Welsh slate. Tall, closely packed buildings shade each other's roofs. These get a hand scrape and biocide, with access planned around the busy streets.

Berry Hill & Christchurch

North of the town towards Symonds Yat. A mix of old stone cottages, bungalows and later housing spread along the lanes, with woodland close by. Slate and concrete tile in roughly equal measure.

Broadwell & Coalway

East of the centre, with a lot of post-war and later housing on concrete tile, plus older cottages in between. Roofs here green up fast where gardens back onto trees.

Milkwall, Sling & Five Acres

Villages on the Forest edge to the south and north-east of town. Bungalows and family houses close to the woods, so shaded roofs and leaf-filled gutters are the usual story.

Clearwell & Newland

Stone villages south and west of Coleford, lower down and more sheltered. Older cottages with slate and clay roofs that need the gentlest approach, and some of the most historic buildings in the area.

Bream

The large village a few miles south, with long rows of older terraced and semi-detached houses alongside newer estates. Slate on the older rows and concrete tile on the newer homes.

Old buildings around Coleford

Cleaning old and listed roofs in Coleford.

The centre of Coleford grew up as a market town around Market Place, and its best-known landmark is the clock tower in the middle: all that is left of the octagonal church built there in 1821 and taken down later that century. Around it, the older streets are lined with stone buildings, and parts of the centre are covered by a conservation area. Out in the villages there is more: Newland's large medieval church, often called the Cathedral of the Forest, the stone cottages of Clearwell, and plenty of old farmhouses and barns along the lanes.

Removing moss and algae from a roof doesn't normally alter the building, so it doesn't normally need listed building consent. Work that touches lime mortar, lead flashings or the original slate fixings usually does. If your job might cross that line we will tell you at the quote, so you can check with Forest of Dean District Council first. The council's offices are in Coleford itself.

On old roofs the method matters more than anything. Old Welsh slate and clay tile can't stand a jet wash, and once a slate is cracked it has to be matched and replaced by hand. So on these roofs we only use a manual dry moss scrape and biocide, we keep biocide off lime mortar, and we leave weathered lead alone rather than scrubbing it back to bare metal.

How a Coleford roof clean works

From survey to finished roof in four steps.

Free survey

We look at the roof, the gutters and how we will reach them, which matters on Coleford's narrow lanes and sloping plots. You get a written price the same day, with no pressure to book.

Moss scrape or low-pressure clean

Old slate and clay get a manual dry moss scrape. Sound concrete tile can have a low-pressure clean instead. Either way, thick moss comes off by hand first so nothing is forced under the tiles.

Biocide treatment

We apply an approved biocide at the right dilution in dry weather. It kills the moss, lichen and algae spores left on the roof, which is what stops it greening up again.

Gutters cleared

We clean out the gutters at the end, including the moss that came off the roof, and the 2-year guarantee starts.

Included with every Coleford roof clean

Free gutter clean and free biocide treatment.

We are already up at gutter level to clean the roof, so cleaning the gutters is part of the job. The biocide is what makes the clean last, so it's included too.

In Coleford the gutter clean matters more than usual. With woodland so close, gutters fill with leaves and twigs as well as the moss washed off the roof, and a blocked gutter sends rainwater down the wall instead of into the downpipe. On an old stone cottage, that water soaks into the stonework. We clear it all out before we leave.

Coleford roof cleaning prices

How much does roof cleaning cost in Coleford?

Most roof cleans in Coleford cost £550–£950, including moss removal, a biocide treatment and a free gutter clean. Bigger, steeper or harder-to-reach roofs cost more. A bungalow or small stone cottage usually comes in towards the lower end; a large detached house, or an old slate roof that needs a careful hand scrape all over, is nearer the top.

What changes the price:

  • The size of the roof and how many slopes it has
  • The roof covering — old slate and clay take a slower hand scrape
  • Access — narrow lanes, sloping gardens and whether we need a tower
  • How much moss there is
  • Single storey or two storeys

Always included: a free gutter clean and the biocide treatment that keeps moss off for up to two years. Gutters on their own start from £90, typically under £150 for a two-storey house.

Coleford roof cleaning questions

Roof cleaning in Coleford: common questions.

How much does roof cleaning cost in Coleford?

Most roof cleans in Coleford cost £550–£950. That covers moss removal, a biocide treatment and a free gutter clean. A small bungalow or a two-up two-down stone cottage sits towards the bottom of that range; a large detached house, a steep pitch or a roof that needs a tower pushes it up. We give a written price the same day after a free survey, with no deposit.

Why do roofs in Coleford get so mossy?

Height and rain, mostly. Coleford sits up on the western side of the Forest of Dean, well above the Severn Vale, and the weather coming in off Wales reaches it first. Add the woodland on almost every side, the shade it throws over gardens and roofs, and the damp ground running down towards Newland and the Wye, and roofs here rarely get a proper chance to dry out. Moss, lichen and algae need exactly that.

Will cleaning damage my slates or tiles?

Not with the method we use. Old Welsh slate and clay tile on the stone cottages around Coleford never see a jet wash: we take the moss off with a manual dry scrape, then apply biocide. Concrete tile on the newer estates can have a low-pressure clean where that suits it better. Either way, the biocide is what stops the moss coming back, not the force of water.

What is the difference between a low-pressure clean and a moss scrape?

They are two separate services. A manual dry moss scrape lifts the moss off by hand with no water on the roof at all, which is the safest option for old slate and clay. A low-pressure clean uses water at low pressure to rinse off moss and staining, which works well on sound concrete tile. Both finish with a biocide treatment. We tell you which one your roof needs at the survey.

My house is in the Coleford conservation area or is listed. Can you still clean the roof?

Usually, yes. Taking moss and algae off a roof does not normally alter the building, so it does not normally need listed building consent. Anything that touches lime mortar, leadwork or the original slate fixings is different, and we will say so at the quote so you can check with the conservation team at Forest of Dean District Council, whose offices are in Coleford, before booking. On old roofs we stick to the hand scrape and keep biocide off lime mortar.

Do you cover the villages around Coleford?

Yes. As well as the town itself we cover Berry Hill, Broadwell, Coalway, Milkwall, Five Acres, Christchurch, Sling, Clearwell, Newland and Bream. The price works the same way in each: it depends on the roof, not the postcode.

Is the biocide safe for pets, gardens and wildlife?

Yes, when it is applied properly. We use approved biocides at the manufacturer's dilution and apply them in dry weather so they stay on the roof rather than running off. Pets stay indoors while we apply it and for an hour afterwards, and we cover and water planted borders. Many Coleford gardens back straight onto woodland or fields, so we take care with run-off at the bottom of every downpipe.

Do you clean the gutters as well?

Yes. Every roof clean includes a free gutter clean, because moss that comes off the roof ends up in the gutters. If you only need the gutters done, gutter cleaning is a separate job from £90, and typically under £150 for a two-storey house. With this much woodland around Coleford, gutters fill with leaves as well as moss, so they are worth checking every autumn.

How long will my roof stay clean?

Up to two years, and we guarantee that. The biocide keeps killing new spores after we have gone, which is what makes the difference in a damp, wooded spot like Coleford. Moss will come back eventually because spores are always in the air, but treated roofs stay clear far longer than roofs that have only been washed.

Is jet washing safe for my roof?

No. A jet wash can crack old slate, strip the surface off clay and concrete tiles and drive water up under the laps. We never jet wash roofs. We use a manual dry moss scrape or a low-pressure clean, finished with biocide, and we tell you which before we start.
