What are the common area of property maintenance that a home owner must deal with?
Maintenance of a home involves addressing the functioning of its main systems: structure, roofing and windows, electrical, plumbing, HVAC (heating, ventilation, and air conditioning). 

Structure refers to the exterior and interior walls, many of which are "load bearing," meaning they support something above them, like a ceiling or a roof. Roofing and windows protect the interior of a home from the exterior conditions, keeping out rain, wind, and insects. Doors fit into this category, too. Electrical systems connect electricity provided by an outside source, such as a power company, into the home for use by appliances, lights, entertainment, and other items powered by electricity. Plumbing systems bring water into, then out of, the home for use in the kitchen and bathrooms. HVAC systems control the interior climate, managing temperature and humidity to make the home comfortable.
