“If facility managers are looking to achieve life expectancies of up to 20 or 30 years, then that ‘detail’ could be crucial”
THE DEVIL’S IN THE DETAIL For building owners and facility managers, dry fixing represents a very simple and inexpensive way to ensure a roof will remain without problems. It has been the preferred method for such repairs in Scotland for more than 15 years, but despite the greater experience north of the border, product comparison there is similarly problematic. However, some features, such as the backing adhesive used on a ridge
or hip roll, can be checked with relative ease. For example, only the highest-performing products bond securely to dusty surfaces, a butyl rubber-backing providing instant adhesion and weatherproofing protection. Those manufacturers, whose products use such material, would typically demonstrate that in published information. However, it is important to emphasise that anything less effective could be at a risk of early failure through the effects of adverse weather conditions during the curing process. The new standard has been designed to prevent this and is likely to cover
vary, so the imminent publication of the new standard – BS 8612 – really cannot come too soon. Designed to provide a benchmark for quality and place a requirement for
manufacturers to publish specific product performance data, it can only be hoped that the standard will finally put pressure on those companies whose products would, in essence, create a liability for the customer, rather than offer long-term performance.
product features that are currently given little consideration, such as fixings and the base material from which dry verge and ridge unions are made. And while the devil is always in the detail, if facility managers are
looking to achieve life expectancies of up to 20 or 30 years, then that ‘detail’ could be crucial.
