Whether flashing goes over or under shingles depends on the type of flashing. For example, with step flashing, the shingles go on top, but they overlap one another. So technically, flashing goes both over and under shingles. But generally speaking, flashing goes under shingles and beneath the house siding. And in most cases, you can't see the flashing from the ground.

• Are you removing my old roof or placing new shingles on top?

• Do you provide a warranty for the work or the materials?
