Leaking Decramastic Roof Tiles 2

I have two areas on the 1980s Decramastic Roof that are leaking (drips) at two ends of the house. I have tried to identify the problem areas myself but have not identified where the water is getting in. I did however notice that metal tiles close to the area of leakage are dented probably from previous owner not walking on tiles correctly. I also went into roof cavity to try and identify the location of the leak when it was raining but no luck seeing much through the building paper.
