Hudson winds and Jersey City weather
Wind coming off the Hudson River can be strong, especially on upper floors and exposed roofs. It tests edge metal, coping and loose membrane. Summer heat, thunderstorms and winter freeze and thaw also work on seams and flashing.
Heavy rain can overwhelm a roof with poor drainage, so ponding water and slow drains show up as ceiling stains soon afterward. We check slope, drains and scuppers closely, because a roof that sheds water quickly usually lasts longer than one that holds it.
Roofs on upper floors are the most exposed, so the edge metal deserves a closer look there.
