The problem is, the existing roof will have had a few skewed nails per rafter holding it in place. When there a tonnes of roof tiles up there holding it down and the fact that in wind conditions that cause a low pressure above the roof individual tiles can lift and essentially negate the pressure differential then the existing roof is fine. Once you remove all the weight with tin and then screw the whole roof together with metal sheeting you have effectively made a giant wing that in the right wind and weather conditions forms a low pressure above the roof and basically lifts the roof off and then typically deposits it in a neighbours pool. New houses have triple grips and purlin straps that hold the roof structure to the house frame or brickwork to prevent this happening, and with stick roofing failure in this area is one of the biggest areas of noncompliance. Technically when you change the roof cover you are meant to get council approval and all of these details would have been part of the building requirements. Many people don't realise this and the roofing guys don't care, they just do what you ask them ie change the times to tin. Are you in WA?

I’m in NSW, on the coast between Newcastle and Gosford. The wind doesn’t usually present a problem but every few decades we do get a damaging gale. Thank you again Simeon.. I will call my certifier for that.
