I have a question regarding my first on top of the roof inspection. I was completing a roof repair inspection and while I was walking on the roof I figured it would feel solid all across as I walked and it did not it had sections were the sleights would feel as if they were loose and it would sink in. To me that is water penetration and would need to be replaced. Also 2 section in the garage ceiling had water spots. One section of the roof had a whole in the roof panel but the other side which was the opposite side did not have a whole. that left me wondering were the water was coming from. In a section further up from the roof the garage roof hip joined the house roof and the flashing edge has a entry point were the slate can be picked up wondering if that could be the cause.
As a newbie and my first roof repair inspection can you let me know if I am correct that the garage roof would need to be replaced or should I say the entire roof should be replace.
