Insulating roofing system for flat roofs

Abstract

A roofing system for a substantially flat roof structure is provided, including a central panel with a substantially concave surface provided with a through hole at the centre for engaging a drainage system of the flat roof, and a first row of panels assembled around the central panel. The row of panels includes tapered side panels interlocked to the sides of said the central panel and tapered corner panels interlocked with adjacent side panels. Optionally at least one further row of side and corner panels may be assembled around the first row of panels. The side and corner panels are shaped so as to retain a constant slope to direct water away from their outside edges towards the through hole of the central panel. The panels are interlocked using a system with shiplap joints.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a roofing system, and more specifically, to such a system for insulating flat roofs while facilitating water drainage therefrom. BACKGROUND OF THE INVENTION [0002] A lot of buildings, houses or the like are provided with substantially flat roofs. Typically, such flat roofs are provided with a water drain for evacuating excess of water in at least one predetermined location. [0003] In this connection, there are known in the art systems for giving a slight slope to a flat roof in order to prevent the build-up thereon of standing water from heavy rain or melted snow. Such roofing systems generally include a plurality of panels or blocks disposed onto the surface of the roof. A well-known system consists of roofing saddles which are assembled on site using triangular panel units. Most of the time, each panel unit of a roofing saddle must be modified on site by cutting or trimming, as necessary, thus introducing a margin of e...

AI Technical Summary

Benefits of technology

[0021] Advantageously, there present invention provides an insulating roofing system for substantially flat roofs having good drainage functions with easy, problem-free installation. In addition, the system according to the preferred embodiments of the invention can be used without effort and material waste as generated most of the time in this construction area. This is accomplished thanks to the simple geometric relationship between the components of the present roofing system. The present roofing system is also versatile and affords various structural alternatives to accommodate a variety of drain configurations.

Problems solved by technology

Most of the time, each panel unit of a roofing saddle must be modified on site by cutting or trimming, as necessary, thus introducing a margin of error and resulting in a defective instalment.

This means intensive labor operation and wastage of material from which the blocks are made.

Moreover, one known drawback of such known systems concerns the tightness of blunt-end joints between the panels or blocks.

Overtime, these joints, which are usually filled with a compound such as adhesives or silicone based compounds, may become deteriorated from exposure to environmental elements and therefore gradually causing the roof to loose some of its insulating properties, and creating what are called “thermal-bridges”.
