Can be used with reinforcing or without for damaged and more frail roofs it is recommended to use Scrimtex Glass Fibre Reinforcingor sika 120 fleece

Aluminum coatings do not perform well on roofs that pond water. Dirt can accumulate in depressions and inhibit the reflectance of the coating. If an aluminum coating is under water for a prolonged period of time, the water may work its way under the coating causing it to peel. Positive drainage is needed to flush away surface dirt and retain the reflective properties of the aluminum coating. Safety recommendation: Do not coat windows, rooflights, glass or translucent sheets. These will constitute a hidden hazard if disguised.
