5/8 inch OSB sheathing cutting in half?


Putting up 5/8 inch osb on my trusses. Wanting to cut OSB sheathing in half the 8 foot demension, there by having two pices that are 2'x8'.
The idea is to reduce weight of the lift on an extension ladder up to my 7/12 pitch roof. I would then join the cut with construction adhesive.
I am 2' centers on my trusses. I am using clips. I will be going with metal roofing.
Can I do this and not loose alot of strength?

The construction adhesive will do absolutely nothing other than make a big mess. With a metal roof, you may be able to use 2x4 purlins instead of osb. Have you also considered using 1/2" osb to reduce the weight? Is this a house, garage, or other? The extra time you will spend doing it that way would probably be better spent on hiring a helper for a day.

Thanks for your quick reply. Already have 5 sheets of 5/8 inch OSB on 7/12 trusses, I had a helper. So I am commited on 5/8".
Tried putting up 3'x8' piece on third row up at ridge, unable to reach. I could do it from the inside maybe.
This is a Sunroom addition 16'x 24". We went with 5/8" OSB for snow loading, pitch probably will help in most conditions though.
