The absence of comprehensive codes of practice makes this book a good source of guidance to the profession on all aspects of work with profiled sheet roofing and cladding, and the benchmark for the resolution of disputes. The book includes sections on aluminium and fibre cement, and cover fasteners, sealants, breather membranes and vapour control layers, composites and health and safety aspects of sheet roofing. The NFRC's weather guidance has also been incorporated into the guide.
