    All of this water retained on the roof will freeze and thaw and causing expansion and contraction and eventually leaks.

    Leaves and debris is gathered around penetrations around HVAC lines and piled up on seams can eventually cause problems as it holds waterIn this photo, you can see the leaves and debris are gathering up and piling up around HVAC units and penetrations.
