Deliveries need space, access, and protection appropriate to the products and site. Storage arrangements should not be improvised around occupied entrances or sensitive landscaping. The contractor should coordinate them with the building's restrictions.
What to do next
Ask where materials will be placed and how access will be maintained. Clarify responsibility for approved staging areas and delivery timing. Keep any loading or structural questions with the appropriate professional rather than assuming every roof or paved surface can accommodate storage.
