HOA/Custom Management Group troubles

My husband and I own a first floor condominium at 15594 e. Arizona Ave in Aurora. June 12th of this year a water leak developed causing continuous water intrusion into our unit through the month of June, for most of July and the first part of August. It was not until mid August that a leak detection company identified a water leak from a common drain line. The leak was repaired but the board and management company have not moved forward with any plans to replace significantly damaged exterior siding and worn roof. By the time plumbing repairs were completed, the rainy season had ceased. In the meantime, our unit sustained significant damage due to the spread of mold which has also affected adjoining units. The association is accepting financial responsibility for restoring the unit but by failing to replace terribly damaged siding and worn roof, they are not in compliance with established covenants. Neglect of common exterior surfaces will produce similar circumstances next time we experience a rainy season. The value and desirability of our property as well as the general health, safety and welfare of the building inhabitants is being adversely affected.
