What Is A Boarded Roof Waterproofing System?
A boarded roof system is a cost effective waterproofing system used in the refurbishment of flat roofing issues. Roofing structures that are of a low pitch or have very little run-off are generally in need of a board waterproofing system in order to allow proper water flow.
Wooden pressed boards are secured to the existing IBR / Corrugated iron roof using flat head roofing screws and nylon washers, creating a “flat roof surface”. Thereafter, the 4mm torch-on waterproofing membrane is installed by means of torch on fusion.
