A certified roofing contractor can be called to prevent further damage to the roof, or personal injury to the landlord caused by trying to inspect his car.

A roof and ceiling system must be adequately ventilated to prevent overheating and moisture retention, two factors that can cause a roof to break prematurely.
Selecting a qualified roofing contractor
A certified, experienced contractor provides various services. Completely tearing an old roof and replacing it with a new one to inspect and "certify" an existing roof. The latter is a process in which the roof is inspected and "guaranteed" to function properly for a certain period of time; usually two years. The contractor is responsible for any necessary roof repairs during that period.
A certified contractor is aware of the types of roof systems, materials and installation procedures best suited to each project, and will ensure that there is adequate ventilation.
Ask roofing contractors likely questions as whether or not they are licensed and bonded. What liability insurance coverage they carry, and if it is current. Make roofing manufacturers that are authorized and approved for installation and product warranty purposes. Also ask if they are members of any of the regional or national trade organizations.
Several resources are available to find a certified roofing contractor; references, licensing agencies of local government, and Web sites offering contractors hire, or a list of contractors who are licensed and bonded.
