These flashings are called pipe boots and are a rubber gasket that seal around the pipes to keep water from entering your home.

The next item is drip edge. It is am L-shaped aluminum that goes around the perimeter of your home. On the eves which are parallel to the ground the drip edge is installed underneath the Ice and Water Shield. On the Rakes which run to the peak of your roof and is installed on top of the underlayment.
