Description
A Cupola Extension Base is an essential accessory for buildings with steep roof pitches. We custom manufacture the actual base to match the exact shape and size of the cupola you order. Therefore, you receive a perfect fit that maintains the structural integrity and aesthetic of your project.
It is important to understand that the extension base is not an additional separate piece that sits on top. Instead, we make the standard base taller to support the steeper pitch of your building’s rooftop. As a result, this modification ensures your cupola sits level and looks proportional on steeper inclines.
Why You Might Need an Extension Base
-
Steep Pitch Support: Standard cupolas typically fit up to a 10/12 or 12/12 pitch. However, if your roof has a 12/12 or 14/12 pitch, you will likely require one or two extension bases.
-
Seamless Integration: We build the extension directly into your unit. Consequently, the transition between the cupola and your roof remains clean and professional.
-
Custom Matching: We ensure matches your chosen material, whether you prefer maintenance-free Azek vinyl or select Western Red Cedar.
-
Simplified Ordering: Simply add the extension base to your cart along with your cupola. In addition, our team will automatically sync the dimensions to match your primary order.
