Joggle-head king-post roofs from the mid Tudor period are not well known, but at Lacock there are four of them. This paper examines the constructional details of this form of roof and the benefits they provided in transferring compression laterally and maximising usable loft space. It focuses on one roof, that over the Abbey Barn, recently tree-ring dated to 1575-80. That such an expensive type of roof should be present over a utilitarian building, a stable block, has attracted some comment but no explanation has hitherto been forthcoming. Close examination of the roof suggested it had been re-used and a sketch of the abbey buildings made in 1684 suggests that it might have belonged to the now lost west range of Lacock Abbey.

都铎王朝中期的铰接王柱屋顶并不为人所知，但拉科克有四个这样的屋顶。本文研究了这种形式的屋顶的结构细节以及它们在横向转移压力和最大化可用阁楼空间方面所提供的好处。它的重点是修道院谷仓上方的一个屋顶，最近的树木年轮可以追溯到 1575-80 年。如此昂贵的屋顶应该出现在实用建筑（稳定的街区）之上，这引起了一些评论，但迄今为止还没有任何解释。对屋顶的仔细检查表明它已被重新使用，而 1684 年绘制的修道院建筑草图表明它可能属于现已失落的拉科克修道院西侧范围。
