2) Lightening – The chance of lightening increases with wet and stormy weather. Lighting can be a severe hazard with both ladders and cranes.
3) Electrical Shock – The risk of electrical shock from power tools is increased with wet water.
4) Quality and Production Decreases – Wet weather decreases production by roofers. The wet weather can also damage the roofing material and installation process. Wet weather can lead to wet roofing insulation and moisture entrapment within the roof assembly.
