Until you put it on a maamid that is meqabel tum'ah. Then it becomes
invalid for sekhakh, but still valid as a maamid.

Your sevara is that of the CI's chumerah (in OC 143:3) that nothing in
the chain of support from the ground to the sekhakh should be a davar
shemeqabel tum'ah. But iqar hadin (unless, perhaps you're living in Benei
Beraq or otherwise in a community of the CI's talmidim) is like the SA
(OC 629:8).

Tir'u baTov!
