What is an inverted roof ? Following an investigation, BRE concluded that water that had been trapped in the roof build-up during construction had condensed between the top of the concrete screed and the underside of the . Simply defined as a type of roof construction where the waterproofing layer lies beneath the insulation instead of above it — as in other forms of roofing — inverted roofs ensure that the complete. The performance and longevity of flat roofs depends upon many factors, including the position of the insulation within the construction. Due to its numerous advantages for flat roofing one of the best solution is the inverted roof construction.
A flat roof system typically consists of the following elements- a structural deck, an air-vapour barrier, insulation, and a waterproof membrane.
Protects waterproofing membrane. Minimal water absorption. Compatible with green roof systems. High compressive strength. Resistant to the passage of water vapour.
Ballasted systems also provide maximum resistance against roof membrane damage and UV degradation, protection against thermal shock, fire or noise and maintain the lowest surface temperature . It helps keep the building cool and also strong enough for mechanical loads. ProTherm G provides the highest thermal performance per mm of any XPS insulation, and is fire resistant.

Bauder Total Roof System is suitable for a variety of applications on both new build and refurbishment projects and can be used in warm, cold and inverted roof scenarios. There is also the option of using a root resistant cap sheet, making this waterproofing system ideal for green roof situations. BBA certification is granted . An inverted roof construction places thermal insulation above the waterproof layer.
Hot melt inverted roofs have many benefits, not least that they can be completely flat. Construction of the inverted roof. In the inverted roof system insulation is laid over the waterproofing layer and suitably loaded . Over the last decade, our Toronto and Calgary roofers have installed numerous inverted roof systems on many high-rise buildings. Regulations relating to the inverted roof have already been established in . Dispersive damp proofing systems.
Mineral systems for ground damp proofing. Solvent-based damp proofing systems. Waterproofing systems for insulated . Click for all the details. An IRMA system is the most common type of roof used on modern high-rises today.
More generically, others may . On a flat roof, thermally insulated with INVERTED ROOF system , the waterproofing layer is reliably protected against environmental impacts with rigid and water resistant XPS thermal insulation, which gives the roof the desired durability.
INVERTED ROOF is the roof of the future. With the revolutionary invention of . The inverted roof is a flat roof construction and its main feature is that, unlike in conventional flat roof designs, the thermal insulation is laid above the Polymer Modified Mastic Asphalt. Inverted Roof Membrane Assembly. Any type of deck or ballast can be selected as a finishing surface such as gravelled or pebbled roofs, paved terrace roofs, green roofs.
Monarplan single ply ballasted roofing systems offer an excellent solution for situations where access or recreation are a priority. This module outlines the key benefits of inverted roof systems and offers guidance on their specification. It is sponsored by Radmat Building Products.
