Introduction to the 2009 edition
Read the new introduction by
Richard Jordan and Tim Ratcliffe
Written by a traditional roofer during the Second World War, this reprint of the 1945 edition presents useful step by step guidance on the right techniques for laying and repairing roofs. It highlights the options for repairing damage rather than stripping and relaying the roof.
The first four chapters describe the timber construction of roofs covering everything from basic joints through to the differences in the design of traditional and trussed roofs. It also provides extensive practical information of the design of pitched and flat roofs, jointing around roof lanterns, fixing lay boards up the pitch of the roofs and the setting out of steps in horizontal gutters. The following chapters describe slates and slating, tiling, wood and asphalt shingles, diamond slating and fibre cement slating.

This edition will transport the older craftsman back to the classroom
and workshop of budding apprentices, struggling to grasp the mechanics
of roof construction. It was to their advantage if Molloy was on their
reading list. This slim volume is packed with traditional roofing
principles that have stood the test of time.
Molloy, clearly a master of his craft, managed to harmoniously blend the structural explanation with the actual details, so often only found in separate books.
Chapters 6 to 10 are wonderfully descriptive, with excellent technical advice for architects specifying, and conservation craftsman working on, roof coverings. Techniques of the period are sound and transferable to any roof covering today. It is rare to find as much roofing detail in one volume for the many differing roof coverings.
I would recommend that this book is a must for the architect and student of conservation, senior craftsmen working on traditional buildings, architectural and surveying students and, possibly, for structural engineers with an interest in conservation. Cornerstone (SPAB)
Roof Construction and Repair, although first printed in 1942, is still relevant to today’s construction industry. The principles and processes relating to the construction and covering of various roof types and shapes have not changed that much over the years. The detail in drawings and descriptions of roof construction would grace any modern day carpenters collection, and assist any young carpenters wishing to work on older buildings and increase the skill and knowledge of their craft.
In conclusion, the appeal of this book would range from professionals to tradesmen in the construction industry and specifically architects and builders working on restoration projects involving roofing works.
Roof Construction and Repair goes a long way to simplify a section of construction which is very often unnecessarily over complicated and seldom written about. A must have for aspiring and experienced roofers alike. Journal of Architectural Conservation
