Beacon Basingstoke Roofing

Roofers in Thatcham

Thatcham is 15.4 road miles north-west of Basingstoke, along the Kennet valley east of Newbury, and a town that grew fast after 1951. Much of its housing went up as the town expanded after the war, and older clay tile and listed buildings stand on and near the A4 Bath Road. We survey with photographs and then commit to one written price.

    Houses built in the growth years

    Thatcham's population climbed rapidly from about 5,000 in 1951, and the housing that absorbed it went up estate by estate through the following decades. Houses of that era are commonly semis, terraces and bungalows under concrete interlocking tiles (the large, overlapping type with a locking edge), with mortared ridges, bargeboards at the gable ends and timber fascias. The roofs are now old enough for the felt underlay and ridge mortar to be showing their age, and original plastic gutters can be brittle and sagging as well.

    Older buildings along the A4

    Some of the town's oldest buildings stand on or near the A4 Bath Road. The former Chapel of St Thomas the Martyr, now the Old Bluecoat School, is Grade I listed, and St Mary's parish church, mostly rebuilt in 1857, is Grade II*. Around them are older houses in brick and clay tile, where lead, chimneys and tile fixings need a careful, sympathetic hand.

    Extensions, garages and flat roofs

    Behind the estate houses are the flat roofs: kitchen extensions, porches and garages, mostly finished in bitumen felt when they were built. Some garages from the period carry corrugated asbestos cement. Thatcham sits low beside the Kennet and the canal, so water that lingers on a poorly drained flat roof has few places to go, and ponding shows up quickly. A garage roof that has been left for years is often cheaper to put right than owners fear, once we have seen what the deck underneath is doing.

Planning and building control in Thatcham

Thatcham sits within West Berkshire Council's area, so planning and building control both run through it. West Berkshire designated Thatcham Conservation Area in June 1980, and you can find the council's guidance through its West Berkshire Council website. Within that area and around the listed buildings on the A4, the council will expect roof work to respect the original materials and appearance of the building.

For a house inside the conservation area, a repair in matching materials usually goes ahead without fuss, whereas a change of covering, a new chimney treatment or a different roof profile may need consent, so talk to the council's conservation team before you order anything. For a listed building, including the Grade I and Grade II* buildings on and near the A4, take the same care. On the estates, taking a whole slope back to the battens and relaying it can be notifiable to building control, and we handle that. For a roof window, our planning permission guide sets out what applies.

What we find on Thatcham roofs

A town that grew as fast as Thatcham has roofs that tend to age together. The estates are now at the stage where the underlay, ridge mortar and fascias start to fail, and the river valley setting adds damp to the mix.

Chapter 1: Why is the ridge on our Thatcham estate house shedding mortar?

What we find

On houses built as part of the town's post-war expansion, the ridge tiles were bedded on sand and cement mortar, as was normal at the time. After decades of frost and sun, the mortar shrinks, cracks and parts from the tiles. Then wind gets under the ridge, and one or two tiles may rock or drop. You may find grit in the gutters, a ridge line that no longer looks straight, or a tile resting on the lawn after a storm.

Estates were built in runs, so neighbouring roofs show similar symptoms at a similar stage. The same goes for the verge, the sloping edge at the gable end, where mortar holds the end tiles and the bargeboard (the board that finishes the roof edge) in place. Failures here let wind driven rain in at the edges of the roof, and the first sign indoors is often a damp patch high on a gable-end bedroom wall.

What we fix

A few ridge tiles come off first, so we can tell whether the tiles themselves are good and only the bedding has let go, which is usual at this age. Current standard BS 5534:2014 expects mechanical fixing for the ridge, hips and verges, with mortar no longer carrying the load alone. Our usual answer is a dry-fix ridge, with tiles clipped or screwed down to a continuous batten, a type of system that BS 8612:2018 covers.

A published cost guide gives a dry ridge on a semi as £900 to £1,600 with scaffold extra, and the figure we give you comes from the survey. If you want to read more, see our ridge tile repairs page.

Chapter 2: Is the damp in our loft near the Kennet a roof problem or a ventilation one?

What we find

Thatcham straddles the River Kennet and the Kennet and Avon Canal, and the air in the valley carries moisture. In a loft, that moisture meets cold timber, and condensation forms on the underside of the felt and on the rafters. It is easy to mistake for a leak because it drips and stains in the same way. A real leak tends to follow rainfall and show at one spot, while condensation shows across the roof and is worst in cold, still weather.

Loft insulation laid right to the eaves can block the ventilation gaps at the bottom of the roof, and a bathroom or kitchen fan that vents into the loft adds more water. The result is black mould spotting on the timber, damp insulation and, over time, rot at the rafter feet.

What we fix

First we find out which of the two it is. We go into the loft in the middle of the day, check the underside of the felt for damp, look at the eaves for blocked ventilation and trace any water back to a point of entry. If it is condensation, the cure is airflow: eaves vents or tile vents fitted, insulation pulled back from the eaves, and extractor fans ducted outside.

If there is also a leak, we repair the cause with the tile, flashing or underlay concerned. Where timbers have rotted, we cut out the bad section and splice in treated timber. The repair sits under the written guarantee we give on our workmanship. The roof inspections page explains how a survey runs.

Chapter 3: After the July 2007 rain in Thatcham, how do I check whether my roof coped?

What we find

Heavy rain in July 2007 affected about 1,100 properties in Thatcham, even though the rivers themselves did not flood. That points to surface water and overwhelmed drainage, and it is a useful reminder of what the town's gutters and roofs can be asked to do in a downpour. A gutter that is blocked, sagging or too small spills over, and the water runs down walls or soaks the fascia.

On flat roofs and extension roofs, a single outlet can be overwhelmed, and any ponding then forces water through weak seams. Look for tide marks under the eaves, damp patches on a ceiling after heavy rain, and a gutter that overflows in the middle of a run, which usually means a sag or a blocked downpipe.

What we fix

We clear and flush the gutters, check the falls (the slope that carries water towards the outlet), refix any sagging lengths on new brackets and replace corroded or cracked sections. Where fascias have been soaked for years, we replace the rotten boards so the new gutter has something sound to fix to. On a flat roof we check the outlet size and clear it, then look at the seams and the deck.

If the flat roof ponds because the deck has dipped, we explain whether a new layer will cure it or whether the boards need replacing underneath. One guide puts EPDM at £80 to £120 per square metre, and what we charge follows the survey. See guttering, soffits and fascias.

Chapter 4: Can the roof of a house near the Old Bluecoat School or St Mary's be repaired without consent?

What we find

The older core of Thatcham, with the Grade I Old Bluecoat School on the A4 and Grade II* St Mary's church not far away, has houses and outbuildings of brick and clay tile that have been repaired many times. Typical faults are slipped tiles where the nails have corroded, cracked flashings at chimneys, and valleys that have failed beneath moss and leaf litter.

The question homeowners ask is what they are allowed to change. The answer depends on whether the building is listed or sits within the conservation area, and on whether you are repairing like for like or altering the roof. A neat repair with matching tiles seldom causes difficulty. Swapping clay for a different material, or altering the roof line, is where consent is more likely to be needed.

What we fix

We start with a photographic survey of the whole roof, so that both you and the council can see what exists. Repairs then use matching clay tiles, reclaimed where possible, fixed with modern stainless or copper nails and clips in place of corroded ones. Lead flashings and soakers are renewed to the existing tile gauge, and brick chimneys are repointed in lime.

Where a roof is worn out and needs more than a patch, we talk through the options before you approach the conservation team at West Berkshire, because they will want to know what is proposed. Bat roosts and bird nests are legally protected, so we advise if the programme needs to work around them. See our chimney repairs page.

Thatcham roofing questions

What does failing ridge mortar look like from the ground?

Look for dark or broken lines along the top of the roof, crumbs of mortar in the gutters, ridge tiles sitting out of line, and visible gaps where the bedding has dropped. Any of those means water can get under the ridge. We re-bed the ridge tiles or fit a mechanical dry-fix system, and the survey photographs show you the failed sections close up.

My estate house was built in the 1960s. Does it need a new roof?

Not necessarily. The concrete tiles on estates of that period are often still sound, while the ridge mortar, the felt at the eaves and the timber fascias go first. From inside the loft we inspect the underlay, and a handful of tiles come up so we can see the battens. If the main roof has years left, we quote the repair, and the work is covered by our 10-year written guarantee.

Can you work near the canal side where access is awkward?

Usually, yes. Thatcham straddles the Kennet and Avon Canal and the river, and some properties near the water have narrow access or limited space for a scaffold. We look at access when we survey and plan the delivery of materials and skips around it, then tell you in the quote how the job will be set up.

Is a roof on a listed building in Thatcham treated differently?

Yes. Thatcham has listed buildings, including the Grade I Old Bluecoat School and the Grade II* St Mary's church, and any change to the materials or look of a listed roof needs consent. We recommend like-for-like repair, record the roof in photographs and give you the survey report to show the council.

What happens to our old roof tiles and waste?

We clear the site and take the waste away at the end of the job. Sound tiles can be reused where the design allows it, and the rest goes to a permitted facility. Asbestos cement sheets on older garages get separate handling following HSE advice, starting with a written risk assessment.
