Roofers in Frimley Green

Frimley Green lies 18.7 road miles east of Basingstoke, strung along the Basingstoke Canal with its old wharf and inn, and on land that falls away towards the River Blackwater. Its roofs range from older houses near the 1911 church to homes close to the towpath. You see the survey photographs before we agree a figure, and the price is then locked in on paper.

Roofs we see in Frimley Green

  • 1930s semi-detached houses with hipped clay tile roofs and bay windows on a suburban road

    Canal-side cottages and wharf buildings

    The Basingstoke Canal runs along the south of the village, where a traditional wharf and an inn still stand. Buildings beside water tend to be damp in a different way: moisture hangs in the air, trees overhang, and moss and algae settle on the north slopes. Older canal-side roofs of clay tile or slate need a gentle hand, and their gutters and valleys collect leaf litter very quickly.

    Older houses near St Andrew's

    St Andrew's Church was built in 1911 and is Grade II listed. On the village's older houses, where the roof is clay tile or natural slate with lead valleys, brick chimneys and timber eaves. They are well built but they have had a long time to weather, and the first failures are in the lead, the nails or pegs holding the tiles, and the timber at the eaves.

    Roofs on the slope above the Blackwater

    The ground drops from Deepcut and the Chobham Ridges in the east down to the River Blackwater, so houses on the higher ground meet more wind than those in the hollow. On exposed slopes it is the edges of the roof that suffer: ridges, verges and the first courses of tile at the eaves. Lower down, the problem is more often damp, shade and slow drying after rain.

Planning and building control in Frimley Green

Frimley Green is covered by Surrey Heath Borough Council for both planning and building control. The council has nine designated conservation areas, and the Basingstoke Canal is one of them, so a house or outbuilding beside the towpath may be subject to extra controls on the look of the building. The council sets this out on its conservation pages, and a short check of your address against them before ordering materials is time well spent.

St Andrew's Church is listed at Grade II, and the same care applies to any other listed building you own. Matching repairs are usually acceptable; a different tile, slate or lead detail may need consent from the council's conservation officer. Away from protected areas, the usual question is building control, because a larger stripping job can be notifiable, and we handle that for you. For roof windows, read our planning guide for roof windows first.

What we find on Frimley Green roofs

A canal on one side and a ridge on the other: the water and the weather both leave a mark on roofs in this village. Damp and shade shape what goes wrong near the canal. Wind shapes what goes wrong higher up. Older, church-era houses add the troubles of lead, nails and timber.

Chapter 1: Why does moss keep coming back on the roof of our house near the Basingstoke Canal?

What we find

Moss needs moisture, shade and a surface it can grip. A house near the canal often has all three: still, damp air from the water, overhanging trees that block the sun, and porous clay or concrete tile that stays wet for long after a shower. On the north slope the roof may never dry out properly in winter, so moss grows thick, and its roots lift the edges of the tiles.

Heavy moss does more than look untidy. It holds water against the tile, which then freezes and flakes the surface in cold weather. It packs into the gaps between tiles and can push them out of line, and the clumps wash into the gutter and block the outlets. If the downpipes overflow every time it rains, a moss-covered roof above them is the first place to look.

What we fix

We clear moss by hand with brushes and scrapers and then treat the tiles with a biocide that kills the remaining growth. We avoid blasting at high pressure, which can strip the surface from tiles and drive water under the laps. Gutters are cleared in the same visit, and any broken or slipped tiles found under the moss are replaced before the treatment goes on.

Hand moss removal with biocide is reported in typical UK guides at somewhere between about £750 and £980, depending on roof size. Your fixed quote follows the survey. If branches are shading the slope, we will tell you, since cutting them back keeps the roof drier. Our roof cleaning page covers the method in more depth.

Chapter 2: Our older house in Frimley Green has slipped slates. Can single slates be replaced?

What we find

On a roof of natural slate, each slate hangs from a nail or a peg through a hole near its top. Over a century or so, the nails corrode and the slates slide down, leaving a gap, or crack where the nail head has bitten. You may find slate fragments on a path or in a flower bed, or see a short dark streak running down the slope where one tile has dropped.

A single slipped slate is a small gap, but water that gets past it wets the batten and underlay beneath, and over time the batten rots. Slate roofs are also easily damaged when people walk on them, so a few cracked slates in one place often point to a past visit from a poorly equipped contractor. A roof that sheds slates widely may be showing that the nails are failing generally.

What we fix

Replacing an individual slate is a standard repair. We slide out the broken one, fix a replacement with a strip of lead or copper called a tingle, and leave the neighbours alone. We use a matching slate from reclaimed stock where we can, because new slate can differ in colour and thickness. If many slates are slipping, we assess whether the whole slope needs stripping and re-fixing on new battens with fresh underlay beneath.

Typical UK figures for a single slate repair are £100 to £250 in labour and a small sum for the slate itself, with a tower or scaffold from £300 to £800 when the roof cannot be reached otherwise. No figure is final until we have seen your roof. Read our slate roofing page for larger jobs.

Chapter 3: Why do tiles keep slipping and ridges lift on the higher, windier part of Frimley Green?

What we find

Where the land rises towards the Chobham Ridges, houses are exposed to wind that has had little to slow it. A roof takes the load in gusts at the edges: the ridge at the top, the verge at the gable and the lowest courses at the eaves. If the fixings there are weak, tiles lift and settle back out of position, and each gust loosens them further. Mortar-bedded ridges are the usual first casualty.

From the ground, look for a ridge line with a dip or a kink, a gable edge where the tiles stick up, or tiles lying in the garden after a storm. In the loft, daylight at the verge or a damp patch on the gable wall points to wind getting under the edge of the roof. The longer a loose component stays loose, the more likely it is to take its neighbours with it.

What we fix

We re-fix the exposed edges rather than patch individual tiles. Ridges and hips are rebuilt with a mechanical fixing, as BS 5534 requires, usually a dry-fix system that is clipped or screwed to a batten and not relying on mortar. Verges are finished with a dry verge cap or with tiles that are properly bedded and clipped, and the eaves courses are checked for the right number of fixings.

On a roof where the whole slope has lost its grip, the answer may be a strip and re-cover, which is notifiable work for building control, and we handle that. The wider decision is explained on our roof replacement page. Whatever the extent, your fixed quote follows the survey, and if the roof still has life in it we say so.

Chapter 4: Is a leak by the chimney on a Frimley Green period house a flashing or a pointing problem?

What we find

Both are possible, and they are different jobs. A stack on a house of this age is made of brick set in lime or weak cement mortar. Around its base, lead flashing seals the joint with the roof, and it is held into a cut slot in the brickwork, called a raglet, by lead wedges and pointing. When the pointing falls out, the flashing drops away and rain runs behind it. When the lead itself cracks from years of expansion and contraction, the leak is in the metal.

A stain on the chimney breast inside suggests a flashing or the stack itself. A stain on the ceiling a little away from it can mean water has run down a rafter. Cracked pots, a missing flaunching and failed brick faces higher up can look like flashing faults from the loft, so the stack deserves a full look from above before anything is ordered.

What we fix

We climb the stack, photograph each face, and note which of the three parts has failed: lead, pointing or masonry. Often a repair means new lead flashings and soakers, a rake-out and repoint in a mortar matched to the brick, and a new flaunching. Where the brick itself is crumbling, rebuilding the top courses may be wiser than repointing, and we show you the evidence in the photographs.

Typical UK costs for chimney leadwork average about £570 and run from £350 to £920, and four-sided flashing is reported at about £525 without scaffold or around £1,000 with it. Treat these as ballpark figures; the survey decides the real one. Detail is on our lead roofing and leadwork page explains the metal side in detail.

Frimley Green roofing questions

Does the damp from the Basingstoke Canal cause moss and algae on roofs in Frimley Green?

Houses close to water and tree cover tend to stay damp and shaded, which helps moss and algae grow. Algae mostly stains tiles and rarely harms them, while thick moss holds water against them. We check the gutters for blockage, look at the tiles for damage under the growth, and suggest brushing or soft cleaning where the surface is sound.

Can you replace tiles on a house next to the canal without disturbing the towpath?

Usually, yes, because the work is on the roof and the access is from the property side. We plan scaffold, ladders and material storage so that nothing blocks a public path, and we clear waste as we go. If a canal-side building is in the conservation area, check what applies with Surrey Heath Borough Council before changing materials, and we can supply the survey photographs for that conversation.

St Andrew's is Grade II listed. Does that affect my own roof nearby?

Not unless your own building is listed or sits in a conservation area. The church's listing applies to the church. Houses around it are treated on their own merits, and ordinary repairs with matching tiles or slate do not usually raise a question. If you are unsure, ask the council's planning team about your address. We can survey and photograph the roof first so you have the evidence to hand when you ask.

Which side of the village gets the worst weather for roofs?

The higher ground towards the Chobham Ridges takes more wind, so ridges, verges and eaves tiles there tend to loosen first. The lower, sheltered parts nearer the Blackwater and the canal stay damp longer, so moss and blocked gutters appear sooner. Neither side is worse overall; they simply fail in different ways. We look at the side of your house that faces the weather and at the shaded slope as well.
