A roof deck is a flat walking deck built above-occupied living space or a roof deck that extends out over an outdoor living space. A roof deck supports the roof elements but does not provide complete protection. Rain Defense works with experienced design engineers to make sure your roof deck is protected with a waterproofing coating. The waterproofing system becomes an integral part of the surface and provides the necessary protection against the elements.
