- Can I specify a custom size dome?
Yes you can. Just give us the required outside diameter and centerline height.
- Does it attach to a sub frame?
No, the roof does not attach to a sub frame. It is self supporting and attaches to a circular wall plate.

You simply need to provide a circular wall plate to receive and support the roof. We will supply an anchor best suited for the structure.
- How are they shipped?
The roofs are made up of individual pie shaped wedges that are bundled, packaged and crated for shipment by commercial carrier to the location of your choice.
- Are they weatherproof?
Domes can be weather proofed by the installer by applying a clear caulk at each rib and or a foam weather strip between the rib joints and roof cap.
- Can I insulate a dome roof?
A sprayed on foam insulation can be used but the preferred method is to place a slightly smaller dome under the main dome. This allows room for insulation, wiring, etc along with an interior view of the roof.
- What is the wind and snow load rating?
While no specific load ratings are available, this style of dome roof has been manufactured for more than 50 years. Hundreds of domes have been installed in heavy snow country, such as upper Minnesota and Quebec. In high wind areas, we recommend and have available inconspicuous wind reinforcing rings.
