The climate does the rest. A Newark roof gets driven rain from summer thunderstorms and freeze and thaw when the winter snow melts, and the weak points are the same in either season: flashing at chimneys and walls, pipe boots, valleys and eaves. Those are the places we would photograph first.
A realtor who reviewed us on Google wrote that when a client's home inspection showed a failing roof, we provided pictures and videos of its current condition. A Newark owner gets the same from us: photos and video of the roof as it stands, the must-do items separated from the recommendations, and a free estimate.
