RDP Housing
Steel is a strong, affordable option for RDP housing projects. Our lightweight steel roofing systems are SANS-compliant, built to handle South Africa’s tough weather – from heavy rain and strong winds to extreme heat. They are also easy to transport, quick to install, and reduce on-site waste.
Traditionally, this market has relied on sheeted roofing systems. In recent years, however, Dezzo Roofing has partnered with a leading concrete tile manufacturer to deliver concrete tiled roofing solutions supported by our lightweight steel trusses. This system has been well received by communities, municipalities, government bodies, and developers.
We offer flexible options to suit different project needs, including:
