Godalming is a market town in Waverley Borough, south-west Surrey, at the confluence of the Rivers Wey and Ock, approximately four miles south of Guildford. Mentioned in King Alfred’s will of 880 AD and in Domesday Book as Godelminge, it prospered through the medieval woollen trade, the coaching era (halfway between London and Portsmouth), and the Wey Navigation (1764). In September 1881, Godalming became the first town in the world to receive a public electricity supply, powered by a waterwheel at Westbrook Mill on the River Wey. Charterhouse School relocated here from London in 1872, its buildings constructed from the distinctive local Bargate stone. Jack Phillips, the Titanic’s senior wireless operator, was a Godalming boy, and the mountaineer George Mallory lived here. The High Street contains 16th- and 17th-century timber-framed buildings with overhanging upper storeys. A roof survey Godalming assessment from £195 understands this town’s exceptional range of building ages and materials.
Godalming’s roofing challenge reflects its geography: a town built across a river valley, from floodplain to hilltop, in a building material found nowhere else. Bargate stone — a dark, honey-coloured calcareous sandstone quarried locally until the Second World War — was used for centuries in chimneys, walls, and churches throughout Godalming. It gives the town its distinctive character. But Bargate stone is porous. It absorbs moisture from driving rain and morning dew, then suffers deterioration when that moisture freezes or crystallises. Chimneys built in Bargate stone require lime mortar, which breathes and allows moisture to escape. When cement mortar is used in repairs, it traps moisture inside the stone, causing exactly the spalling and crumbling it was intended to prevent.
Properties in the Wey valley — along Bridge Street, Catteshall, and the areas between town centre and Lammas Lands — sit on alluvial deposits with a high water table. The Wey has flooded seriously in 1968, 1990, 2000, 2013, and 2020. Even between flood events, the water table in the floodplain keeps ground moisture permanently elevated. This moisture migrates upward through walls into roof timbers. Properties on the higher ground at Charterhouse, Holloway Hill, and Frith Hill sit on free-draining Greensand and face different challenges: wind exposure across the hilltop rather than valley moisture from below. A £195 survey identifies which set of conditions your property faces.
For homeowners: A £195 roof survey reveals whether Bargate stone deterioration, river-valley moisture, or hilltop exposure is creating the hidden damage that affects your roof.
For buyers: Before committing £350K-£1.5M+ on a Godalming property, a £195 roof survey reveals how centuries of Wey valley conditions have affected the roof — and whether previous repairs have used compatible materials.
Nearby Areas: We also cover Guildford, Haslemere, Milford, Witley, and Bramley.
A couple purchased a three-bedroom Bargate stone cottage near the town centre for £625K. Handmade clay tile roof, two Bargate stone chimney stacks, timber-framed upper storey with tile-hanging, garden running down towards the Wey floodplain. The purchase survey described the roof as “clay tile covering in generally satisfactory condition, chimney repointing recently completed.” No specialist roof survey was commissioned.
Year 1: Damp appears around the main bedroom fireplace during autumn rain. Owners assume the recent chimney repointing has resolved any issues and attribute the damp to internal condensation.
Year 2: Damp worsens. Patches of Bargate stone on the main chimney’s windward face are visibly flaking. The “recent repointing” noted in the purchase survey was done in cement mortar. Roofer checks externally — replaces two slipped tiles near the chimney and reseals the lead flashing with mastic. Cost: £450. Notes the stone is “crumbling a bit on one side.”
Year 3: Specialist investigation reveals the cement repointing is the primary cause. Bargate stone is a porous calcareous sandstone that naturally absorbs and releases moisture through lime mortar joints. The cement repointing has sealed the joints, forcing moisture sideways into the stone. Trapped moisture is freezing in winter and causing the Bargate stone to spall and crumble on the exposed face. The lead flashing, which was originally dressed into sound stone, now sits against a crumbling surface and no longer maintains a seal. The second chimney shows the same early signs. The garden’s proximity to the Wey floodplain means ground moisture is also migrating up through the walls, adding to the moisture load the chimneys must manage. Both chimneys require complete removal of cement pointing, restoration of lime mortar, partial rebuilding of spalled sections with reclaimed Bargate stone, and new lead flashings against restored surfaces: £12,000-£18,000.
What a £195 Roof Survey Would Have Shown Before Purchase: “This Bargate stone cottage has recently repointed chimneys using cement mortar — incompatible with calcareous sandstone. Windward face of main chimney already showing frost-spalling from trapped moisture. Lead flashings losing bond against deteriorating stone surface. River proximity elevating ground moisture. Budget £8,000-£12,000 for cement removal, lime mortar restoration, partial stone rebuilding, and flashing renewal.”
The Lesson: In Godalming, “recently repointed” can mean “recently damaged.” Cement mortar on Bargate stone is not maintenance — it is the beginning of the stone’s destruction. A £195 survey identifies incompatible previous repairs before you inherit the damage they cause.
Professional roof surveys in Godalming require understanding of Bargate stone behaviour — how this uniquely local calcareous sandstone absorbs moisture, demands lime mortar, and deteriorates when cement is used. We assess river-valley moisture migration from the Wey floodplain, hilltop exposure at Charterhouse and Holloway Hill, timber-frame condition in the town’s oldest buildings, and the compatibility of previous repairs with original materials. We combine RICS-registered qualifications with specialist knowledge of Godalming’s exceptional range of building materials and conditions.
From 16th-century timber frames to Bargate stone cottages to Victorian terraces in Farncombe, professional roof survey Godalming assessment from £195 provides material-aware, position-specific intelligence. We assess Bargate stone compatibility, river-valley moisture, hilltop exposure, and the critical question of whether previous repairs have helped or harmed your building.

Bargate stone is porous and naturally absorbs moisture. Lime mortar is softer and more permeable than the stone — it allows moisture to evaporate through the joints rather than being trapped. Cement mortar is harder and impermeable, forcing moisture sideways into the stone where it causes frost damage and salt crystallisation. Over time, cement literally destroys the stone it was meant to protect.
In floodplain properties, yes. The high water table along Bridge Street, Catteshall, and the Lammas Lands area keeps ground moisture permanently elevated. This moisture migrates upward through walls, especially in older buildings without effective damp-proof courses, reaching wall plate level and creating conditions that promote timber decay in the roof space.

Very. Hilltop properties at Charterhouse, Frith Hill, and Holloway Hill sit on free-draining Greensand and face wind exposure but not ground moisture. Valley properties near the Wey face ground moisture and flood risk but are more sheltered from wind. Our surveys assess your specific position and its specific consequences.
Godalming combines historic market-town character with excellent transport links. Godalming station provides South Western Railway services to London Waterloo (~45 minutes). The A3 is nearby via the A3100. Guildford (4 miles) provides wider shopping and employment. Charterhouse School provides a significant educational draw. The town has independent shops, the Wey Navigation towpath, and Winkworth Arboretum (National Trust) nearby. Properties range from £300K for flats and smaller homes to £500-800K for town houses and Victorian properties to £800K-£1.5M+ for substantial period houses and Bargate stone properties.
At these values, a £195 roof survey Godalming assessment is essential. Understanding whether Bargate stone repairs are compatible and river-valley moisture is under control could prevent a £5,000-£20,000 surprise.
