No to vinyl. Aluminum unless your rolling in cash then copper
True enough. But I will assume the homeowner knows just enough about gutters to realize their primary function is to catch water run off from a roof line. And given that there seems to be an issue "where there are no gutters (side of the home) the rain is starting to erode some spots of the soil exposing some deep parts of the slab foundation." I'm going to assume it is some sort of hip roof configuration without a complete gutter system.No one can see your house from here without a picture.
What style roof is it?
Gable roofs do not have gutters on the ends.
And then make sure they actually put aluminum on the house. :smile:If you get quotes for aluminum, make sure the quotes specify the gauge of aluminum that is to be used.
