Chapter one
Roofs of the Shepherd's Meadow generation
Houses from the 1990s are old enough now for ridge bedding, verge pointing and underlay to be worth a close look.
When the Chidham and Hambrook parish boundary was redrawn in April 2003, it brought the whole Hambrook community into one parish. By then the village had already taken most of the parish's new housing, built north of the railway after 1995, among it the 36 houses of Shepherd's Meadow in 1999. A roof from that year has been through more than a quarter of a century of weather. That is not old for a tile, but it is old enough for the parts around the tiles to start telling a story, and a survey reads that story from the edges inwards.
At a glance
- Shepherd's Meadow, 36 houses, dates from 1999
- Ridges laid before 2014 may rely on mortar alone
- Concrete tiles often last 30 to 60 years
1.1 Ridge and hip bedding
Ridge tiles cap the highest line of a roof, while hip tiles cover its sloping corners. On a house finished before 2014, these were quite possibly bedded in mortar and nothing more. The 2014 revision of BS 5534 changed the expectation, and a bedded ridge now carries a mechanical fixing as well. If you can see hairline cracks in the mortar, or the odd pale crumb on the ground below, that bed has begun to let go. Our ridge tile repairs page explains the repair choices, including a dry-fix ridge.
1.2 Verges and the first gale
The verge, where a roof finishes against a gable wall, is another spot where mortar works hard in the open air. A cracked verge lets wind get under the last tiles, which is how a gale turns a small defect into a missing tile. We look at the verge from the ladder, press the tiles gently, and photograph anything that moves.
1.3 Underlay and the loft
Moisture in a loft, which comes from the house below it, needs a way out. Marley's advice for ventilating a cold roof laid with high-resistance underlay is a 10 mm gap along the eaves once the pitch passes 15 degrees. So on a loft survey we look at the eaves, not just at the tiles.
