Farm Building Roof Assessment for Solar

Every farm building is different. Before designing a solar system, we conduct a thorough roof assessment covering material identification, structural capacity, orientation analysis, and condition evaluation. This guide explains what we look for and why it matters.

What Our Farm Roof Assessment Covers

A comprehensive agricultural building survey examines four critical areas to determine solar feasibility, optimal system size, and expected financial returns.

Farm Roof Types and Solar Compatibility

The roof material is the single most important factor in determining installation method, timeline, and cost. Here is how each common agricultural roof type works with solar.

Structural Load Calculations

The structural assessment ensures your building safely supports solar panels through their entire 25+ year lifespan under all weather conditions.

Highlights

• Panel Dead Load
• 12-15 kg/m²
• Weight of panels, mounting rails, and fixings. This permanent load must be within the roof structure design capacity.
• Wind Uplift
• Varies by location
• Panels increase wind uplift forces on the roof. Fixing calculations account for the specific wind zone and building height.
• Snow Loading
• 0.3-0.7 kN/m²
• UK snow load zones affect the combined dead plus imposed load calculations. Highland areas require additional structural margin.
• Purlin Spacing
• Typically 1.2-1.8m
• Mounting rails span between purlins. Standard spacing of 1.2-1.8m is ideal. Wider spacing may need intermediate support rails.
• Column Loading
• Cumulative check
• Total additional roof load transfers through columns to foundations. Portal frame buildings generally have adequate reserves.
