Cautioning signs ought to be raised and any passageways closed off. While surveying the delicacy of a rooftop, various variables must be thought about: - Thickness of the material - The range between upholds - Sheet Profile - The sort, number, position and nature of trimmings - The plan of the supporting design - The age of the material The age of the material specifically is a significant factor to consider. After some time material can decay so what might have been considered safe when initially raised, can become delicate over the long run. For certain rooftops, the risk might be obvious to see.
