Stacked or Built Up Molding
Moldings may be stacked or built-up to create a larger moulding or merge 2 or more mouldings. You may also build up a molding by sumply adding styrofoam underneath of it, thereby pushing the molding out further from the wall. This is particularly effective when your molding is large and you only want a portion of it to follow along a deviation in a straight wall. Building up moldings also adds depth to the molding and eases the transition between the eavestrough or roof and the wall.
In the example below, the molding breaks off into 2 parts - one following the gable and the other running along the bottom of it.
