Roofing Feature raising the roof Innovations in roofing mean greater possibilities in construction, safety and design aspects throughout the house. P rogression in the building and construction industry in the twenty-first century requires us to look at old methods and improve on them. In striving to work faster, more safely, more cheaply and in a more sustainable manner there is a continual focus on building methods, products and materials and how they can be advanced. Constant advancements in roofing technologies have meant that a roof is now easier and quicker to construct or install with increased structural integrity and design possibilities. Construction Tubular metal scaffolding was introduced to Australia in 1937. Since then, the strengthened safety regulations and the need for greater efficiency on site have seen a range of improvements made to the system. Once requiring a team of skilled tradespeople to assemble, welded frames were developed to clip or slot scaffolding together to reduce the time spent erecting it on site. The reduction in the complexity of the system and in construction time resulted in a reduction in labour costs and required less skill in assembly. Bear in mind that a scaffolder’s ticket is still required to undertake scaffolding work above a specified height in all jurisdictions, e.g. four metres in most instances. Today, scaffolding systems can be easily transportable, versatile and quick to construct. The Frame Scaffold System from Molecular Scaffolding is one such system, and provides scaffolding solutions for all trades on site. By setting up the scaffold deck initially for installing the fascia/gutter system, it can then be readily used to install the roofing. The fall protection height can easily be extended to two metres above the deck with mesh guards or hand rails to ensure the safety of roof installers. The main deck can be easily altered for other trades and the convenient ‘clamp on, hop up’ brackets can be set up at any height. Molecular Scaffolding’s Frame Scaffold System has been designed to improve safety, productivity and profitability, and it is even available in a trailer pack. Once perhaps unthinkable, the trailer packs can be assembled by two men in two hours, cutting labour time in half, and disassembled to fit easily back into the trailer for storage and transport.
