MECHANICAL SYSTEM REQUIREMENTS FOR A VA HOME LOAN
Mechanical systems must be:
• safe to operate, and
• protected from destructive elements

Heating must be permanently installed and maintain a temperature of at least
50 degrees Fahrenheit in areas with plumbing.
In areas with a mild climate, heating may not be required.  Air conditioning is not required, but if installed, must be operational. If any
needed repairs to the air conditioning equipment are apparent, the appraiser
must prepare the appraisal subject to the repair of the air conditioning system
by a licensed heating/air conditioning contractor.

ROOF REQUIREMENTS FOR A VA HOME LOAN
The roof covering must:
• prevent entrance of moisture, and
• provide reasonable future utility, durability, and economy of
maintenance.
When a defective roof with three or more layers of shingles must be replaced,
all old shingles must first be removed.
The appraiser is not required to climb onto the roof

When the appraiser is unable to view the roof, the appraiser must explain why
the roof is unobservable and report how the condition of the roof was
determined. For example, a roof may be covered with snow yet the appraiser
observed no evidence of leaks and documentation was provided to the
appraiser verifying the age of the roof. If available, other methods such as
drones could be utilized to show the area.
