Can You Put A Cupola On A Metal Roof?

We understand the importance of an eye-catching metal roof cupola. Metal roofing requires a ventilation system to keep your building cool and dry. Cupolas are an inexpensive way to do just that because they are very effective at ventilating a barn’s metal roof and extending its lifespan. Installing a cupola on any roofing material may be difficult if not done correctly. Cupolas installed on top of a metal roof will provide that aesthetically pleasing look. You could also match the roof of your cupola to the roof of your building in both color and style. Our metal roof cupolas are crafted using only the finest materials and quality. Our unique styles and designs ensure that you will find the exact cupola you need. Click the button below to learn how our cupolas can transform your structure into an aesthetically pleasing part of your property.

What Is The Purpose Of A Metal Roof Cupola?

Do Metal Barns Need Metal Cupolas?

Metal roof cupolas are not required for metal barn roofs. Because of their durability and long-lasting abilities, vinyl cupolas are among the most commonly used on metal roofs. Vinyl cupolas are moisture-resistant and require little maintenance, making them perfect if your structure is exposed to the elements or you live in a climate where you experience harsh weather systems.

Vinyl cupolas have a lot of customization options and come in various designs and styles. Metal roof cupolas tend to rust and corrode over time which will cause them to lose their “new look” much quicker than a vinyl cupola. Vinyl is also lightweight and easy to install when compared to metal which can weigh a lot more, making it tough to lift to the top of your building.

How Long Will My Metal Roof Cupola Last?

Metal roof cupolas are very durable and can often go on for years without much maintenance. The aluminum or copper roofs will keep rain from rotting or hurting the integrity of your cupola for an extended period of time. It usually isn’t very convenient to climb up to your cupola for maintenance, but if you have the option of yearly cleanings, it will make a difference in the lifespan of your cupola.

Debris, dust, and dirt can cause the louvers to become blocked over some time, so cleaning your metal roof cupola every year or two is a great tip for maintaining a clean look. The durability of vinyl can not be overstated; you will not have to worry about it being infected with termites or rotting away. Vinyl does not need to be painted or stained, which is one of the main reasons that most wooden cupolas don’t last nearly as long.

How Do You Secure A Cupola To A Metal Barn?

Securing a metal barn cupola is simple; we recommend you use non-ferrous screws, which are resistant to moisture that would cause rust to form on the screws. You can also use nails to secure a cupola to a metal barn; cut an appropriate opening for the cupola and screw the cupola to the roof rafter and install a supporting wood in the cupola’s base screw or nail it to the side of the rafter. We recommend that you use 2×4 lumber for the supporting lumber.

Cupola Installation On a Metal Roof

The pitch of your metal roof will determine how your cupola will fit. Most roofs have a pitch of 6:12 or 4:12. This is good information to have when you are looking to buy a cupola. A cupola should also be proportioned appropriately to your metal roof. An easy way to measure what size cupola will fit your structure is that a cupola should be an inch wide for every foot of metal roof.

As we described above, it will need a platform to rest on. The platform can be built using framing lumber or plywood. Once the platform is attached to the roof rafters, you can attach the cupola to the platform using screws and adhesive. As the last step, you will want to use caulk or some other sealant in the seams between the roof and the cupola to keep water from leaking into your structure.

The last step is to enjoy the improved ventilation your new cupola provides, as well as the sharp appearance of your barn or shed!
