High performance roof insulation is crucial to this process, particularly flat roofs, which are susceptible to issues not applicable to pitched installations. Snow, wind, ice and rain are elements that pose a serious issue for roofs in a poor state of repair. For a flat roof in need of replacement, precipitation is a familiar foe in winter months. Indeed, according to Met Office figures, between 2006 and 2020 the UK suffered four of the wettest winters on record, with the trend predicted to continue. When the weather deteriorates, therefore, ensuring flat roofs have efficient water run-off measures in place is crucial to reducing the risk of deflections forming, which leads to ponding and in a worst-case scenario, water-based structural damage. For efficient water dispersal, choose tapered roofing insulation When installed as part of a flat roof’s waterproofing build-up, tapered roofing insulation’s multifunctional design manages a roof’s water run-off, ensuring it flows into appropriate outlets or gutters. This not only helps increase the lifespan of the waterproofing and the roof itself, the tapered roofing insulation’s thermal performance can reduce instances of cold bridging which can lead to damp spots forming at junctions between the roof and wall. In terms of considerations when it comes to selecting a suitable tapered roofing insulation, a full survey of the roof itself ought to be a prerequisite. It’s particularly pertinent when installing modular single-layer insulation systems, which are manufactured off-site and cannot be cut or altered once delivered to site. A survey determines a roof’s dimensions, taking into account potential obstructions or openings such as rooflight and drainage outlets, which could affect the layout of the high-performance insulation scheme. It will also highlight any backfalls or deflections that need to be overcome. Which is the best tapered roofing insulation option: single-layer or multi-layer? Bonded under factory-controlled conditions, single-layer tapered roofing insulation systems are the time and cost-effective alternative to multi-layer solutions in flat roof installations. Ready to install once delivered to site, the insulation within the single-layer bond will have been monitored for its volume and minimum coating adhesion performance, leaving installers with the relatively straightforward task of installing it – in one block – to the roof, followed by the waterproofing. This not only guarantees the insulation will perform as-designed, it significantly reduces application times and material waste. Therefore, whilst a multi-layer solution might appear, on paper at least, to be a more cost-effective option, the benefit is negated by the additional hours it takes to bond and install the tapered roofing insulation layer-by-layer; a process that is eliminated with a pre-bonded single-layer system.
