How do I read age from this printed on the roof?

[MPdesign]

This is a new age format (for me)!

Thank you for your insight.

Carlisle uses the last 2 letters. IH = '98

BTW, I highly recommend Carlisle's low-slope roof training.

Thank you Bill,

What is that training called? I made a search for it, but I am not having any luck.

And is there an age lookup list so that I will know other dates?

i.e.

1998 = IH

1999= ?

etc

H = 9

I = 8

Count the alphabet alphas ...

A = 1

B = 2

C = 3

etc.,

BTW - I'm only guessing ....

A-I = 1-9. I don't remember what letter for zero.

Carlisle does like 2 dozen seminars each year for EPDM and TPO. Most are in PA and Texas and a few way out west. I think they also present at other organizations' conferences. My contact was Michelle.Varner(at)syntec.carlisle.com.

They have on-line courses too. I'll look for my bookmark when I get back in tonight.

Here's the on-line course list:

For anyone doing commercial inspections, I suggest starting with Introduction to Commercial Roofing. Then Intro to EPDM & Intro to TPO.

If you only do residential, you probably won't see TPO.

This is great. Thank you!
