Our coop proprietary lease states that tenant shareholders bear sole responsibility for the repair and maintenance of their terrace structures who have excluse use of their roof terraces reasonable wear and tear excepted.

One of our apartments has had numerous repairs and decks built over the years on its roof terrace by various owners.

The present owner wants to build a new wood deck due to rotting of the old one. The coop has advised him to replace the existing roof as it has not been replaced in over 15 years. He feels it is the coop's responsibility not his. Since previous owners have repaired and built structures on the exclusive terrace roof, isn't the present owner responsible for the repair of his exclusive roof terrace?
