Cupolas with the Madison copper top or a Canterbury style are also a nice choice for colonial homes. After about a month, the polished copper finish will tarnish to a brownish color. You may lightly lacquer the copper top to delay tarnishing. However, discoloration, cracking or peeling will occur over time. The roof pitch refers to the angle or the steepness of your roof.
Builders can use a carpenter's square to find the angle of a roof.
