Description

AN ARRANGEMENT AND METHOD FOR SEALING A GAP BETWEEN TWO ROOF
MODULES
The present invention relates to an arrangement and method for installing a roof. In particular, the present invention relates to an arrangement and method for sealing a gap between two sections of a pre-fabricated roof.
Pitched roofs are traditionally manufactured from roof trusses comprising wooden frames which are set upon the brick or timber-framed walls of a building, usually on a wall plate, the wall plate defining the upper surface of the uppermost portion of the wall. A layer of waterproofing material is laid over the trusses and battens are mounted thereupon which in turn supports tiles, slates or an alternative outer roof covering. Roof manufacturing and installation is time consuming and labour intensive and many factors affect the task such as differing weather conditions, site location and health and safety considerations. Pre-fabrication of roof sections, wherein the trusses, battens and roofing materials are assembled in a factory and not on-site, mitigate these problems as the roof can be manufactured in a controlled, familiar environment and transported to the site to be installed. However, a problem with pre-fabrication of roof sections is that because the roof is installed in pre-made sections, it is possible that the gap between the sections can allow water ingress if not properly sealed. There are no bespoke methods or apparatuses for sealing an abutment between pre-fabricated roof sections; fulfilling this requirement could improve the weatherproofing of such roofs as well as the efficiency of installation.
It is an object of the present invention to mitigate the above-mentioned disadvantages regarding the installation of pre-fabricated roof sections.
