Readyslate® modular design ensures complete waterproofing and seamless integration with any existing roof element. The four-step installation utilises the same style of flashing and finishing systems we have been using with our Owens Corning Roofing System over the last 25 years. Valleys, ridge, hips and other inclusions can be combined with Readyslate® utilising these tried and tested New Zealand roofing designs.
