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 !!!!

Huh??? Explain that again?? Am I missing something or did you state that both the drip edge and ice shield go on first??
