45x40 Vertical Roof Barn
Building Description
The 45x40 Vertical Roof Barn is ready to tackle just about anything. It features bright Galvalume walls and roof with Burnished Slate trim. This crisp silver and slate look feels clean and modern. Three front garage doors give easy access to a wide, open interior. An enclosed lean-to adds a secure storage room on the side. Windows bring in natural light. Use it as a haven for vehicles or an organized workshop. Store lawn mowers, farm equipment, hay, and livestock feed. Vertical roof panels shed rain and snow.

45x40 Vertical Roof Barn FAQs
Answers about the 45x40 Vertical Roof Barn, including pricing, layout, product options, free delivery and installation, and local project requirements.
The 45x40 Vertical Roof Barn is currently listed at $29,725. Final pricing varies by state, certification requirements, and customizations. Free delivery and installation are included. Request a quote for your chosen configuration and address, and confirm site preparation and foundation costs separately.
The center measures 35 by 40 feet. The enclosed right lean-to is 10 by 30 feet and sits toward the back, so it does not run the full building length. Use the final drawings to plan usable floor area, access, and storage zones rather than multiplying overall width by length.
Confirm permits, zoning, setbacks, foundation requirements, and required wind, snow, and seismic design criteria with your local building department before ordering. Requirements depend on your address and intended use. Ask ProBuilt which certification and engineering documents are available for your project; a listed wind rating alone does not guarantee local approval.
The supplied configuration measures 45’W x 40’L x 12’H. The layout includes center building: 35’W x 40’L x 12’H (Roof Length 41’); right lean-to: 10’W x 30’L x 8’H, 2/12 Roof Pitch, Aligned Toward Back, Ends & Side Closed. Overall dimensions may include open coverage or shorter lean-tos; confirm enclosed areas and clearances in the final drawing.
Yes. Free delivery and installation are included with ProBuilt buildings. Prepare the site to the agreed requirements before the installation crew arrives. Confirm site preparation, foundation work, access, and any additional project costs in your quote; included installation does not establish that concrete work is included.
