Desktop roof survey form, ready to send.
Everything our structural engineers need to turn your roof into a signed Desktop Structural Roof Loading Report. Send the measurements and photographs across four short sheets. Site wind, snow, altitude and exposure are derived from the postcode by us. Eurocode-verified, MIS 3002 V6.0 compliant, signed by a qualified structural engineer.
One form. A signed engineering report.
This is the information request behind every Desktop Structural Roof Loading Report we issue. Complete the fields that apply to your roof, attach the photographs, and email it back. We do the engineering: site wind, snow, altitude and exposure from the postcode, load combinations to BS EN 1990, and a verdict signed by a qualified structural engineer. Built for solar installers, EPC contractors, asset managers and developers preparing a commercial roof for solar PV.
Site & roof construction
The site address and postcode, roof type (flat, mono, duo or hipped), the roof build-up, and a quick visual condition check: corrosion, rot, previous repairs, or added plant that changes the design load.
Dimensions & member sizes
Building length and width, eaves and apex heights, parapet height, bay or frame spacing and purlin spacing. Member sizes where the structure is accessible, or internal photographs with a tape measure in shot.
Site & roof photographs
Aerial or hand-held photographs of the full site and the roof: monopitch, duopitch, hipped or flat, so the structure, the surface and any obstructions are clear to the engineer.
Internal frame photographs
Photographs of the internal frame, the connections and the roof profile, so the load path can be read from the structure itself and nothing is assumed.
Required to issue a signed report
The minimum an engineer needs to put their name to the load assessment.
Helpful, not essential
Where available, these sharpen the report and cut the engineering assumptions.

Desktop survey form questions
What is a desktop roof survey?
A desktop roof survey, or Desktop Structural Roof Loading Report, is a remote structural assessment of whether a roof can carry a proposed solar PV array. It is produced from measurements, photographs and design data you supply, without a site visit. Our engineers derive wind, snow, altitude and exposure from the postcode and check the roof against the array, mounting system and ballast to BS EN 1991-1-4, BS EN 1991-1-3 and BS EN 1990.
What information do I need to provide for a desktop structural survey?
The full site address and postcode, your roof type and the dimensions that apply to it, the panel make and model, the mounting and fixing specification, and, for flat-roof ballasted systems, the ballast design. Photographs of the roof and internal frame complete the picture. The downloadable form sets out every field across four short sheets.
Do I need to provide structural drawings?
No. Drawings and original design calculations help where they exist, but they are not required. Where the structure is accessible, member sizes or internal photographs with a tape measure in shot let our engineers size the members instead.
How much does a Desktop Structural Roof Loading Report cost?
Desktop Structural Roof Loading Reports start from £130 per report for residential and new-build properties, and from £150 per report for commercial properties. No VAT is added to our fees, so the published figure is the price you pay. Volume pricing applies from 10 sites upward.
How long does a desktop report take?
Reports are issued within our 48-hour benchmark from confirmed scope, once the completed form and any required design data have been received.
Do I need a structural engineer for solar panels?
MIS 3002 V6.0, mandatory from 18 June 2026, requires a suitably competent person to confirm the existing roof can carry the array, the mounting system and the wind and snow loads acting on it. The standard does not name who that person must be. On a commercial roof, our standard is that the competent person should be a qualified structural engineer, which is exactly what a Desktop Structural Roof Loading Report provides.
