Stonehouse roofs, specifically

Where the Stroud valley meets the Severn Vale.

Stonehouse sits about three miles west of Stroud, at the point where the Frome valley widens out and runs onto the flat land of the Severn Vale, with the M5 just beyond Eastington. That position gives local roofs two different kinds of weather. Down on the valley floor, the River Frome and the Stroudwater canal keep the air around Ocean, Bridgend and Ryeford damp, and mist sits low on still autumn mornings. Out on the western and northern edges of town, roofs are more exposed and take the wet south-westerly weather that blows in across the vale. Doverow Hill rises to the north and Selsley Common to the south-east, so some streets are sheltered and some are not, and that changes how quickly a roof turns green.

The housing is a mix you don't find in many Stroud district towns. Stonehouse was a brickmaking town for over a century, and the Stonehouse Brick and Tile Company worked here from 1891 until 1968, so many of the Victorian and Edwardian houses near the centre are brick rather than Cotswold stone. After the war came the Park Estate in the 1950s and later Rosedale, built on the old brickworks site, along with developments such as Court View. Most recently, Great Oldbury on the north-west side of town was given permission in 2016 for up to 1,350 homes, so a good number of the town's roofs are now less than ten years old.

Each of those roofs needs a slightly different approach. A young concrete tile roof at Great Oldbury usually needs a light low-pressure clean to lift algae before it turns into moss. A 1950s roof on the Park Estate may be carrying decades of moss on tiles whose surface has softened with age. Slate and clay on the older terraces, and the stone roofs in Kings Stanley and Leonard Stanley, get a manual dry moss scrape only. Every job finishes with the same biocide treatment, which is what stops it coming back.

What we clean in Stonehouse

Four kinds of roof we see across Stonehouse.

The age of the house usually tells us which method the roof needs.

Modern concrete tile with dry-fix ridges and verges

The usual roof at Great Oldbury and on the town's other recent developments. It's still in good condition, but north-facing pitches pick up dark algae streaks and lichen spots within a few years. A low-pressure clean worked down the slope lifts the growth without driving water behind the plastic verge caps or the mechanically fixed ridge, then biocide stops it returning.

Older concrete tile on the post-war estates

Found across the Park Estate, Rosedale and other estates from the 1950s onwards. After this long the surface of the tiles has worn rough, so moss holds on thickly, especially in the joints and along the ridge. We lift the heavy growth first, then use a gentle low-pressure clean or a hand scrape depending on how worn the tiles are.

Slate and clay on Victorian brick houses

The brick terraces and villas near the High Street and off Bristol Road date from the town's brickmaking years. Slate and old clay tiles crack under foot and under pressure, so these roofs get a manual dry moss scrape from roof ladders, with no water used, followed by biocide.

Cotswold stone in the older villages

Stone roofs on older cottages and farmhouses, more common in Kings Stanley, Leonard Stanley and the hamlets towards Selsley than in Stonehouse itself. Stone is soft and porous, so it's scraped by hand only and treated with biocide, keeping clear of lime mortar at the verges.

Listed and conservation work

The canal corridor, Stonehouse Court and the older village cores.

Most of Stonehouse is ordinary housing with no special protection, but the town has heritage in pockets. The Stroudwater canal, cut in 1779 and now being restored, runs right through it, and the canal corridor falls largely within the Stroud Industrial Heritage Conservation Area. Along it you'll find mill buildings and canal-side houses at Ocean, Bonds Mill and Ryeford. Stonehouse Court, the Grade II listed manor house beside St Cyr's Church, stands on the site of the original manor, and just across the valley at Kings Stanley is Stanley Mill, one of the district's best-known listed mills.

For homes in these areas, cleaning moss and algae off a roof doesn't normally need consent, because nothing about the building is altered. Work to mortar, lead or original roof coverings may need it. On older roofs in these areas we use only the manual dry moss scrape and a biocide applied at the right strength, and we keep it off lime mortar. If anything looks like it crosses into repair work, we'll tell you so you can check with Stroud District Council before booking.

Around Stonehouse

The parts of Stonehouse we cover.

One price list for the whole town and the villages around it, with no travel charge.

Great Oldbury

The large new estate on the north-west side of town, near the M5. Open, exposed roofs of modern concrete tile, where the first signs are usually algae streaks rather than moss. A light clean and biocide early on keeps them looking new.

Park Estate & Rosedale

Post-war housing, Rosedale on the site of the old brickworks. Many of these roofs have never been cleaned, and the worn concrete tiles hold thick moss that sheds into the gutters every winter.

High Street & Bristol Road

The older centre of town, with Victorian and Edwardian brick houses and slate or clay roofs. Some are three storeys at the back, so we plan ladders and roof ladders carefully at the survey.

Bridgend, Ocean & the canal

Homes on the valley floor beside the Frome and the Stroudwater canal, where the air stays damp and trees shade many roofs. These are the roofs that go green fastest in Stonehouse, and biocide matters most here.

Ryeford & Ebley

The stretch east towards Stroud along the canal and the A419, with a mix of older mill-side houses and newer homes. It's the same valley damp as Bridgend, on a wider range of roofs.

Kings Stanley, Leonard Stanley & Eastington

The villages south and west of town. You'll find more stone and clay here, and older cottages beneath Selsley Common, as well as modern housing on the village edges.

How a Stonehouse job runs

Four steps. Same on every roof.

Free survey

We check the tiles, the ridge and verges, the gutters and the access, then tell you which method your roof needs and give you a written price. There's no obligation to book.

Low-pressure clean or moss scrape

Modern concrete tiles get a low-pressure clean. Slate, clay, stone and anything fragile get a manual dry moss scrape. Loose moss is bagged and the gutters are cleared as we go.

Biocide treatment

We apply an approved biocide across the whole roof at the right strength. It kills the moss, algae and lichen spores that are left on the tiles, including the ones you can't see.

Two-year protection

The biocide keeps working after we've gone, which is why our guarantee runs for two years. Most roofs stay clear well beyond that.

The method

Low-pressure clean or moss scrape: why we choose for each roof.

Because Stonehouse has such a wide range of housing ages, there's no single right way to clean a roof here, so we offer two separate services. The first is a low-pressure clean. It suits sound concrete tiles, which covers most of Great Oldbury and much of the post-war housing. A gentle flow of water, directed down the slope with the tile laps, rinses off algae and loosened moss without wearing the surface of the tile. On dry-fix roofs we're careful at the plastic verge caps and the ridge so water isn't forced behind them.

The second is a manual dry moss scrape. We use it on slate, clay and stone, on older concrete tiles that have gone soft, and anywhere water could get in. It uses hand tools only and no water at all: we work down the roof clearing moss from the joints and laps, then bag it so it doesn't end up in your gutters or flower beds.

Either way, the biocide treatment that follows is what keeps the roof clean. We don't use jet washing on any roof. It may look quick, but it strips the surface off concrete tiles so they soak up water and grow moss again faster. It can also crack slate and clay and drive water underneath, so the damage often turns up months later as a leak.

Why bother cleaning it at all

What moss does to a Stonehouse roof if it's left.

On a newer house the main reason to clean is to keep the roof in good condition. Algae and lichen on a ten-year-old concrete tile roof do no harm at first, but they hold moisture, and moss soon follows into the joints. Getting a biocide on early is a small cost that keeps a young roof looking the way it did when you moved in, and it helps when you come to sell, since many neighbouring homes at Great Oldbury were built at the same time and buyers can compare them side by side.

On older houses, it's about protecting the roof itself. Moss soaks up rain and keeps the tiles wet, and when winter frosts freeze that water it slowly breaks down the surface of concrete tiles and can crack slate and clay. Moss also washes off into the gutters, and a blocked gutter on a brick terrace sends water down the wall, which leads to damp patches and damaged pointing. That's why we clear the gutters free with every roof clean.

It doesn't need to be done often. A proper clean and biocide treatment lasts for years on most Stonehouse roofs, so for most homeowners it's an occasional job rather than a regular bill.

The offer, on Stonehouse jobs

Gutters and biocide included with every roof clean.

We're up on the roof anyway, and the moss we clear lands in the gutters, so we clear them as part of the job. The biocide is what gives you two years of protection, so that's included too.

Stonehouse roof cleaning prices

How much does roof cleaning cost in Stonehouse?

Most roof cleans in Stonehouse cost £550–£950, including moss removal, the biocide treatment and a free gutter clear. A semi or terrace on one of the estates usually comes in towards the lower end. Large detached houses, three-storey town houses and roofs with heavy moss or awkward access cost more. Because roofs vary so much, we give you a fixed written price after a free survey rather than a guess over the phone.

What affects the price:

  • The size of the roof and how many slopes it has
  • The tile: modern concrete suits a low-pressure clean, while slate, clay and stone need a slower hand scrape
  • Access, such as conservatories, extensions or a steep drop at the back
  • How much moss has built up
  • Whether it's two or three storeys

Gutters on their own: gutter cleaning starts from £90 and is typically under £150 for a two-storey house. It's free with any roof clean. See gutter cleaning for Stroud and Stonehouse →

Stonehouse common questions

Roof cleaning in Stonehouse: your questions answered.

My Great Oldbury house is only a few years old. Does the roof need cleaning yet?

Often not yet, and we'll say so if that's the case. Most Great Oldbury homes went up after planning permission was granted in 2016, and a concrete tile roof that age usually shows nothing worse than a few dark algae streaks on the north-facing pitch. Moss tends to arrive later, starting in the gaps between tiles and along the ridge. If you send us a photo we'll tell you honestly whether it's worth doing now or whether a biocide treatment in a couple of years is the better buy.

Can you clean a new-build roof with dry verges and a dry ridge?

Yes. Most of the newer homes in Stonehouse have plastic dry verge caps and a mechanically fixed ridge instead of mortar. These are sound, but water driven hard at the joints can find its way behind them. We keep our low-pressure clean working down the slope with the laps of the tiles, never up into the verge caps or ridge joints, and where the moss is thin we simply scrape it off by hand and apply the biocide.

Why is only one side of my Stonehouse roof going green?

Because that side stays damp. Moss and algae need moisture more than anything, so the north-facing pitch, which gets little direct sun from October to March, is nearly always the one that turns. Homes close to the River Frome and the Stroudwater canal around Ocean, Bridgend and Ryeford also sit in the damp air of the valley floor, and roofs shaded by the mature trees along the canal and around Wycliffe College dry out more slowly again.

What's the difference between your low-pressure clean and a moss scrape?

They're two separate services and we recommend whichever suits your roof. A low-pressure clean rinses moss and algae off modern concrete tiles with a gentle flow of water, nowhere near the force of a jet wash. A manual dry moss scrape uses hand tools only, with no water at all, and it's what we use on slate, clay and stone or where a roof can't take water. Both finish with a biocide treatment that keeps killing spores for up to two years.

Is jet washing safe for my roof?

No. A jet washer strips the protective surface off concrete tiles, which makes them more porous so moss comes back faster, and it can crack slate and clay or push water up under the tiles. That's why we only ever use a low-pressure clean or a hand scrape, followed by biocide.

Do you work on listed or conservation-area roofs around the canal?

Yes. The Stroudwater canal corridor through Stonehouse falls largely within the Stroud Industrial Heritage Conservation Area, and there are listed buildings close by, such as Stonehouse Court beside St Cyr's Church. Removing moss and algae doesn't normally need consent because nothing about the roof is altered, but repairs to mortar, lead or original tiles can. Older stone, slate and clay roofs get the hand scrape only, and we'll flag anything that might need a word with Stroud District Council before we book.

How much does roof cleaning cost in Stonehouse?

Most roof cleans cost £550 to £950, including moss removal, the biocide treatment and a free gutter clear. A typical Great Oldbury semi or a Park Estate house usually sits towards the lower end, while larger detached homes, three-storey town houses and steep or awkward roofs cost more. We give you a fixed written price after a free survey, with no deposit to pay.

Do you clean gutters in Stonehouse on their own?

Yes. On its own, gutter cleaning starts from £90, and a typical two-storey house in Stonehouse comes in under £150. With a roof clean it costs nothing extra: the moss we lift off the tiles lands in the gutters, so clearing them is part of finishing the job.

How long will my roof stay clean afterwards?

The biocide carries on working for up to two years after we leave, and that's what our 2-year guarantee covers. Exposed roofs on the open western edge of town often stay clear for longer, while a north-facing pitch under trees by the canal may need a top-up a little sooner.

Is your Stonehouse roof turning green?

A low-pressure clean or a hand moss scrape, then biocide, with your gutters cleared free. Fully insured, with a no-obligation written quote the same day.
