FLL,I hope that you put the ice shield up before you installed the drip edge.It's probably not critical on an unheated building, but the ice shield does no good unless it comes in direct contact with the wood sheathing.

drip edge goes up first than the ice sheild due to if water does get underneath the shingles the water will run down and over the drip edge !! if ice shield is put on first than the drip edge and water is under shingle it would run down ice shield and under the drip edge it into soffit or the over hang of the eaves

and yes it is common for roofs to be shingled over a few layers but watch the local building code as to how many layers you can have up there !
and if doing a reshingel, ( shingling over exsiting shingels ) put on ice shield is not recomemned as it will stick to the shingles but when it warms up it will create ripples in shingels plus if not laid on bare wood it voids the warrenty of the ice shield

well enough of this

back up on the roof for me !!!!
