Roof Leaking. Hoa Wants Me To Pay. Master Deed Seems To Imply Otherwise

Location: Massachusetts, United States

Townhome style. My home is your typical "studs inward" master deed. Prior owner had a wood stove with a metal flue/chimney out the roof for exhaust. The wood stove HVAC was removed prior to my purchase, though the roof exhaust wasn't removed. Water (and snow melt) is now leaking through that exhaust. I am not sure if the prior owner installed the wood stove, and it could've been an owner prior to them.

Beyond the walls of my attic is a space between my attic and the roof, which is defined as a "common area" in my deed, which I will quote

Each unit includes the ownership as to the attic, the area bounded as follows: as to the floor the upper surface of the subflooring of the attic floor; as to the upper extremity, the plane of the lower surface of the chords of the roof trusses which serve as the ceiling joists; as to the walls, the plane of the interior surface of the wall studs, all of the utility lines which exclusively service the unit which are located within the unit, and the built in air conditioner

I've mitigated the immediate damage by putting a bucket down, taking pictures, notifying the board. They are implying that I will be responsible for removal and repair. However, the master deed seems to imply that it's not my responsibility anymore. It's not connected to my unit in any way, shape, or form; and hasn't since I owned it. The roof exhaust was likely installed decades ago (potentially 30-40 years) and no documentation (or agreements) of this work exists anymore.

Am I responsible for a roof modification that isn't connected to my unit?
