FLAT ROOF BALLAST CHIPPINGS
Flat Roof Ballast Chippings
Specialised flat roof aggregates can help to protect flat roofing membranes from ultra-violet rays of the sun which cause deterioration and provide a protective layer for light traffic. Aggregates can also be used to weigh down the insulation on inverted roof designs. By laying fair coloured aggregates on the membrane, heat absorption is controlled. They can also provide a decorative area bringing the flat roof area into a usable environment for inhabitants to relax and enjoy.
To provide a reasonable embedment and interlocking opaque surface, stone sized approximately 10mm-20mm are suitable. Low porosity materials prevent water absorption, which can result in frosted slippery surfaces. Larger cobbles 50-75mm can also provide an effective and visually attractive solution.
