Callahan Steel Building supplies cupolas from Plyco Corporation

Cupolas and Weathervanes make distinguished additions to homes or any other outdoor structure. Cupolas can be used for ventilation or as a decorative accent. Most of our Cupolas are purchased as decorative accents - you don't have to cut any holes in the roof. A cupola can easily be added to your home with or without a weathervane and all cupolas come ready to install a weathervane.

• Callahan Steel offers cupolas in 24", 36" and 48" sizes with a straight roof.
• 24" and 36" cupola is constructed of 29 gauge pre-painted steel.
• 48" cupola has a 26 gauge steel roof.
• Pre-painted steel roof available in numerous colors, sides are standard in white. Contact us for other colors.
• Bird screen included for mounting in curb.
• Roof interlocks with sides for tight connection.
• All metal joints feature "Tog-a-Loc" construction, for non-rusting permanent construction.
• Optional curb cap if no airflow for ventalation is required.

Before deciding which style cupola you're interested in, you should figure out what size cupola will fit your roof.

How to choose the right size cupola:

A good rule of thumb for selecting the right size cupola is to take 1.25 times every foot of unbroken roofline - the key is the unbroken roofline measurement.
