pine needles

I have a 3 year old metal roof that is leaking very badly. The installer told me that it is because of pine needles on the roof. The pine needles usually slide off and do not remain on the roof. My home owner insurance adjuster said that the screws need to be replaced because the rubber has broken down. Can any of this be true?

A quick google seach indicates that pine needles are acidic as they decompose. Steel roof panel systems are not typically designed with corrosion protection against elevated acid levels. It sounds reasonable to me to replace the screws with larger diameter screws. Also, keeping pine needles cleared off the roof should extend the life of the metal roof panel system.
