Digest 351 Re-covering old timber roofs
Publication Year
1990
Document Status

Abstract
When an old timber roof is re-covered, it can be subjected to substantially higher loads by the new tiles or slates than by the original ones. The roof, comprising rafters, purlins, struts and ceiling joists, which has performed satisfactorily before re-covering, may show signs of distress and may eventually collapse as a result of heavier and/or more absorbent tiles or slates. This Digest explains how to assess the condition of timber roofs prior to re-tiling or slating and suggests practical steps towards completing a satisfactory renovation.
