Internachi Florida Life Expectancy Chart
Internachi Florida Life Expectancy Chart
The following chart details the predicted life expectancy of appliances, products, materials, systems and components for homes in the state of Florida. (It may also be applicable to states in the nearby coastal region with similar climate and weather conditions on a typical basis.)
While many components and systems in homes located in Florida and the surrounding area have service life expectancies that are comparable to those anywhere else in the U.S., those items that are regularly exposed to saltwater, wind, sun and heat are particularly vulnerable to premature failure compared to items installed in homes located elsewhere. These guidelines attempt to address those differences.
Consumers, inspectors and professionals advising their clients should note that 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 can shorten life expectancy, especially in coastal regions that experience a lot of sunshine and heat, as well as wind-driven rain. Additionally, conditions of high humidity indoors or outdoors can affect the lifespan of these components, which is why they should be maintained seasonally.

Copper-plated wiring, copper-clad aluminum, and bare copper wiring are expected to last a lifetime, whereas electrical accessories and lighting controls, such as dimmer switches, may need to be replaced after 10 years. GFCIs could last 30 years, but much less if tripped regularly.

The mineral content of water can shorten the life expectancy of water heaters and clog showerheads. Also, some finishes may require special maintenance with approved cleaning agents per the manufacturers in order to last their expected service life. PLUMBING, FIXTURES & FAUCETS YEARS ABS and PVC Waste Pipe 50 to 80 Accessible/ADA Handles 100+ Acrylic Kitchen Sink 50 Cast-Iron Bathtub 100 Cast-Iron Waste Pipe (above ground) 40 Cast-Iron Waste Pipe (below ground) 50 to 60 Concrete Waste Pipe 100+ Copper Water Lines 70 Enameled Steel Kitchen Sink 5 to 10 Faucets and Spray Hose 15 to 20 Fiberglass Bathtub and Shower 20 Gas Lines (black steel) 75 Gas Lines (flex) 30 Hose Bib 20 to 30 Instant (on-demand) Water Heater 10 PEX 40 Plastic Water Lines 75 Saunas/Steam Room 15 to 20 Sewer Grinder Pump 10 Shower Enclosure/Module 50 Shower Doors 20 Showerheads 100+ (if not clogged by mineral/other deposits) Soapstone Kitchen Sink 100+ Sump Pump 7 Toilet Tank Components 5 Toilets, Bidets and Urinals 100+ (if not cracked) Vent Fan (ceiling) 5 to 10 Vessel Sink (stone, glass, porcelain, copper) 5 to 20+ Water Heater (conventional) 6 to 12 Water Line (copper) 50 Water Line (plastic) 50 Well Pump 15 Water Softener 20 Whirlpool Tub 20 to 50 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. ROOFING YEARS Aluminum Coating 2 to 6 Asbestos Shakes 30 to 50+ Asphalt Shingles (3-tab) 10 to 12 Asphalt (architectural) 15 to 20 BUR (built-up roofing) 5 to 15 Clay/Concrete 80+ Coal and Tar 18 Copper 50+ EPDM (ethylene propylene diene monomer) Rubber 10 to 15 Fiber Cement 18 Green (vegetation-covered) 5 to 20 Metal 17 to 20 Modified Bitumen 10 Simulated Slate 10 to 25 Slate 50+ TPO 10 to 12 Wood 25 Exterior siding materials typically last a lifetime. Some exterior components may require protection through appropriate paints or sealants, as well as regular maintenance. Also, while well-maintained and undamaged flashing can last a long time, it is their connections that tend to fail, so seasonal inspection and maintenance are strongly recommended.
