A landlord's residential lease agreement states, "The tenant agrees to take the rental property as is." The tenant is solely responsible for any and all:

Heat problems typically relate to the functionality of the heating system, which is a critical aspect of maintaining a habitable living environment. Such issues are usually considered the landlord's responsibility to repair, as they affect the tenant's right to a livable property, contrary to the cosmetic nature of upgrades.

Mold issues often pose serious health risks and are indicative of underlying structural or maintenance problems within the property. Landlords are generally obligated to address such health hazards to ensure a safe living environment, making mold remediation the landlord's responsibility rather than the tenant's.

Roof repairs are critical for the safety and integrity of the property and typically fall under the landlord's responsibilities. Structural issues like roof damage require professional intervention and are not the tenant's obligation, as they can significantly impact the livability of the rental space.
