Thanks Nick, good reference to give to a client as part of my reports.
:)
Under Appliances, Dishwashers is listed twice; once with a 9 year expectancy and the other with a 10 year expectancy.
Also no EPDM reference under roofing.
Andrew, that is because one is a Sears and the other a Maytag. :twisted:
Neither is TPO and BUR as with many others.
Damn you guys are fussy. :mrgreen:;):)
Check now
Really? Check now.
Keep em comin
By the way…
Nick has hired each of us at the office our own temp to use and abuse. So be expecting a whole lot more projects from InterNACHI over the winter.
Nice work Rob. Thanks for everything you do for the Members.
Well appreciated here. 
How about adding a life expectancy for various foundation perimeter drainage piping…
Vinyl windows missing also.
I’m shipping all that are contributing a bunch of cool free stuff. Thanks so much for helping.
Residential boilers have a life expectancy of 25-30 years and often much longer if it has a cast iron heat exchanger.
A few more items here that could be added;
Laminate countertops
Hollow core interior doors
Solid core interior doors
Folding and bi-fold doors
Smoke Detectors
Metal Roofs
Wood Gutters
Composite decks
Pressure treated lumber decks
Here are the ones I do not agree with:
Cast Iron waste - should be listed as above ground 60+ and underground 50 to 60.
Laminated veneer lumber - This is indoor material and should last 80+ or 100+
OSB should be much higher if not subjected to water 80+
Asphalt roof shingles - many quality choices are available, 15, 20, 25, 30, 35 40, 45 year shingles I would list this as 75 to 125 percent of the original warranty rating depending on environment.
Underground PVC - this would be much higher like 80+
Some of the 100+ year items (cabinets/doors, showerheads, toilets etc) are dependant on use. I’m sure we’ve all seen them that didn’t make it to 100. 
Perhaps for items that we physically open, close or otherwise affect daily, there should be some type of disclaimer.
Hate to have a client call in 10 years wanting a new toilet because his only lasted 30 years.
I agree Rick, these life expectancies are estimates that can vary with use, geographic area, use, abuse, and conditions that could affect it’s normal use.
Therefore the title; InterNACHI’s life expectancy chart
should be more fitting to read;
InterNACHI’s Estimated Expectancy Chart
:)
How about the life expectancy of home inspectors???
2 to 4 years :)
I see an electric range listed but no gas range?
I see a dryer listed but no washing machine?
How about attic fans?
I see you also added EPDM.
Thank You
