Brick parapet material

Galvanized or aluminum copings are better. Even for parapets that already have stone or concrete coping to preserve the coping they cover it with some metal sheeting.

Copper is used in quality jobs mostly in historical buildings sparingly because of the cost.

The reasons metal sheeting is the preferred method:

• Continuous flashing with easy to shop build shedding details, grooves and drip lips, and joint seams. a practical way of accommodating changes in the width and height of the parapets.

• Durability and low maintenance.

• Ease of remodeling and modifications down the road.

• flexibility to accommodate the thermal expansion.

Stone and concrete will eventually crack at the seams and let the rain and freezing damage it.

EDIT

I have attached a diagram detailing galvanized coping on a concrete and a brick parapet wall.

In the lower picture notice, the stone coping on parapet has failed to protect the building
