Who is responsible for the solar leakage that permeates the penthouse?

Legal analysis: the parties first apply to the property company for maintenance, and the property company directly or together with the owners' committee (owners) applies to the property maintenance fund management center. For commercial housing, the warranty period of roof waterproof layer is 5 years. Therefore, if the top floor of the purchased building leaks during the waterproof warranty period, it is the responsibility of the developer, and the developer has the obligation to maintain it free of charge.

Legal basis: Article 40 of the Regulations on Quality Management of Construction Projects Under normal use conditions, the minimum warranty period of construction projects is: (1) the basic works, foundation works and main structure works of housing construction are the reasonable service life of the projects specified in the design documents; (2) 5 years for roofing waterproof works, toilets, rooms and external walls with waterproof and anti-leakage requirements; (3) The heating and cooling system consists of two heating periods and cooling periods; (four) electrical pipelines, water supply and drainage pipelines, equipment installation and decoration works, for 2 years. The warranty period of other projects shall be agreed by the employer and the contractor.
