Component Life Expectancies

Typical life expectancies for most components found in homes are listed below. These life expectancies have been determined through research and testing based on regular recommended maintenance and conditions of normal wear and tear, and not extreme weather (or other) conditions, neglect, over-use or abuse.  Therefore, they should be used as guidelines only, and not relied upon as guarantees or warranties. 


Surface preparation and paint quality are the most important determinants of a paint’s life expectancy. Ultraviolet (UV) rays via sunshine can shorten life expectancy.  Additionally, conditions of high humidity indoors or outdoors can affect the lifespan of these components, which is why they should be inspected and maintained seasonally.

The life of a roof depends on local weather conditions, building and design, material quality, and adequate maintenance.  Hot climates drastically reduce asphalt shingle life.  Roofs in areas that experience severe weather, such as hail, tornadoes and/or hurricanes may also experience a shorter-than-normal lifespan overall or may incur isolated damage that requires repair in order to ensure the service life of the surrounding roofing materials.
