roofing 67 Guaranteed results
Mark Parsons of Russell Roof Tiles explains how, in the light of challenges posed to NHBC guarantees by roofing, a pick and mix approach to specification isn’t always the best option.
W
ith more and more new homes being built, it is essential that there is a focus on constructing
properties are constructed to a high specification. Raising standards is one of the cornerstones of the National House Building Council (NHBC), the UK’s leading standard-setting body and provider of warranty and insurance for new homes. The NHBC is supporting builders, both large and small, to improve quality for buyers. The latest housing statistics from the NHBC
New Home Statistics Annual Review showed that in 2015, 75 per cent more new homes were registered than in 2009. In total 156,140 new homes were registered – representing an eight- year high in housebuilding. The NHBC also reported in November that post-referendum new home registrations are in line with 2015. This
consequently translates into increased sales of building products. One of the continuing challenges to the
NHBC and its Buildmark cover (a 10-year guarantee against structural damage to certain parts of the home) is roofing defects. In 2015 roofing accounted for 12 per cent of claims in the first two years and 55 per cent of all claims in years three to 10. Roofing contractors are often disproportion-
ately blamed for many of these problems. In fact, it is estimated that only about 25-30 per cent of the problems are workmanship-based, and much of the remaining 70-75 per cent can be designed out by the correct detailing, better coordination of the trades (e.g. fascia board heights), or the use of dry-fix systems. In Britain, we’re experiencing an overwhelm-
ing change in climate, especially in the last decade. With winds of over 100 mph being recorded in localised areas of the country there is no room for substandard roofing installation. To reflect these changes, the latest version of BS 5534 British Standard for Slating and Tiling was created. The standard details the mechanical fixing requirements of roof tiles, ridge and hip tiles. Most roof tiles will require an increased number of fixings, with all interlocking tiles requiring a minimum of one fixing, and all perimeter tiles requiring at least two. The ever-changing British weather is not the
only challenge to modern roofing. A mix and match approach to products can be problematic. In terms of specification for tiles, accessories and fittings, mismatched products frequently cause a problems.
