What if there is no application procedure for roof maintenance in old residential areas?

The staff of the Municipal Construction Bureau replied: According to the provisions of the Consumer Protection Law, the quality warranty system is implemented for commercial housing. Under normal use, the anti-leakage warranty period of roofing waterproof works, toilets, rooms and external walls with waterproof requirements shall not be less than eight years, and the warranty period of other parts shall be implemented in accordance with state regulations; The warranty period shall be calculated from the date when the commercial house is delivered to the consumer, and special funds for property maintenance shall not be used during the warranty period. * * * Some residential areas need to be repaired or updated due to damage. Over the warranty period, the residential area where the owners' committee has been established may, with the consent of the relevant owners, apply to the owners' committee for the use of special funds for property maintenance, determine the maintenance plan and entrust it to a professional maintenance unit, and the required funds shall be extracted from the property maintenance fund; If the property management is not implemented or the owners' committee is not established in the area where the property is located, the community residents' committee shall exercise the corresponding duties on its behalf.
