Hips and ridges on Newick's hipped roofs
The Manor House gained its hipped roof in the late 17th century, and every hip since has needed holding on against the weather.
The Manor House in Newick, formerly Church Farm, is a timber-framed building dated 1599. In the late 17th century its roof was changed to the hipped type and its south front refaced in brick. A hipped roof falls away on all four sides, so instead of one ridge between two gables it has hips, the angled ridges that run from the main ridge down to each corner. That is more line to keep sound than a gable roof of the same footprint, and each metre of it is capping that wind and rain can work at.
At a glance
- The Manor House roof was made hipped in the late 17th century
- Hips and ridges are mechanically fixed under BS 5534
- Dry-fix systems are tested to BS 8612:2018
1.1 What goes wrong on a hip
Every course of ordinary tile has to be cut to meet a hip, so a hip holds more joints than anywhere else on the roof. Water gets in where the hip meets the ridge, where mortar cracks along the capping, and at the foot, where the bottom hip tile can creep down the slope when its support rusts. From the ground we look for lifted capping, dropped mortar and tiles that have slid. In the loft, daylight at the hip or a dark stain on the hip rafter tells us which of those is happening. Hip irons, the metal brackets screwed to the rafters at the eaves, stop the lowest hip tile sliding; they rust, and when one fails the whole hip can creep.
1.2 Mortar, clips and the 2014 revision
Mortar alone used to be the usual way of holding ridges and hips; the 2014 revision of BS 5534 ended that reliance, and bedded tiles and fittings are now mechanically fixed as well. Marley points out that working to BS 5534 is not itself required by law, yet it is the benchmark any careful roofer follows on a tiled roof. BS 8612:2018 sets the tests that dry-fixed capping must pass, with clips, not mortar, holding the ridge, hip or verge. The 2018 amendment concedes that heritage roofs may not suit all of its recommendations, so on an old building we talk to the planning authority and conservation advisers before changing the method. A re-bed costs far less than a new roof, so when the tiles are sound it is the first repair we price. Our ridge tile repairs page compares the two approaches, and our pitched roofing page covers a whole slope.
