Traditionally, flashing the critical areas of a roof has been a time consuming, highly skilled and labour-intensive job. Depending on what material is used, it can be potentially hazardous to the end user and environment. Neil Brown, National Sales Manager at Hambleside Danelaw, discusses the issue of flashing materials and the lead alternative flashing from the Danelaw range, Fast Flash, and why it was developed.
What are the issues surrounding the use of lead flashing?
Lead has been used as a traditional and successful roof flashing material for centuries and it has undoubtedly stood the test of time, but as a result of increasing environmental concerns and the continuing problems with lead theft, manufacturers are responding to a demand for alternatives. Modern materials offer lightweight solutions that are easier and safer to handle at heights. Preformed options have also been developed to speed up installation and offer a long service life at a far lower cost than traditional metals, such as lead, zinc and copper.
There is a need within the roofing community to understand better the risks that lead presents to the users and the environment. Of course, these issues can be negated by minimising the use of lead products. Under the Control of Lead at Work Act, there is a duty of care on all to use an alternative to lead whenever and wherever there is one available. This is something that material suppliers and distributors should be aware of to ensure high-levels of health and safety whilst working on site.
With the current move towards greener methods and an increasing number of countries placing restrictions on the use of lead, Hambleside Danelaw’s lead-free flashing provides installers with an environmentally friendly alternative that has none of the associated health and safety risks when working with lead. Due to its non-toxic properties, Fast Flash has the ability to resist standing rainwater and can be used wherever there is a requirement to collect and recycle water without producing harmful run-off, making it a sustainable solution for any greywater system.
What is Fast Flash and why was it developed?
Fast Flash from Hambleside Danelaw has been developed to provide installers with a good quality lead-free alternative flexible flashing material. It requires no tools to fit, is easily workable by hand or with a lead dresser if required, and takes a fraction of the time to install when compared to lead. To ensure that time is not lost during wet weather conditions, Fast Flash has been developed so that it can be installed onto damp surfaces using Fast Flash Adhesive.
Comprising of an aluminium mesh, encapsulated in a polymer rubber, Fast Flash can be stretched in length by 60 percent and in width by 20 percent to suit a variety of detailing requirements. This means that it can be dressed down into pantiles and around upstands, and is ideally suited to forming saddles of the tops of the Valley Troughs and Bonding Gutters. Four widths are available, 140mm, 280mm, 370mm and 560mm of five-metre length rolls and in three colours, Traffic Grey, Tile Red and Black, meaning that customers have a wide choice for different applications. It comes with a 10-year guarantee, which can be extended to 20 years with the addition of painting the surface of the flashing with a sealant that is used for protecting and repairing - FlashSeal. For additional sealing at the joints or on top of Fast Flash that has been applied to difficult details, Fast Flash Adhesive can be applied.
Fast Flash has been designed to be fully self-adhesive with a perforated backing film that allows installers better positioning and half an hour to adjust and reposition for neat and accurate detailing. Additionally, by being fully self-adhesive, all offcuts can be used for detailing or use elsewhere to help ensure that wastage is kept to a minimum. The secure and durable flashing is compatible with a number of Hambleside Danelaw’s products especially the range of rigid GRP flashings such as Valley Troughs and Bonding Gutters.
