Commercial Structural Design & Calculations: Roof Calculations

If you are considering alterations or extensions to your property, or changing its use, an in-depth insight into the structural implications is crucial.

For PV Panels, Green Roofs and Plant Machinery

Structural roof loading calculations are an integral step when making alterations such as PV panel installation, when adding substrate, vegetation and drainage systems to create living roofs, and when installing new plant machinery.

Your structural engineer will assess the load capacity of the roof and provide calculations for building and planning control purposes. They will also consider the suitability of the roof system, looking at pitch, height, access, climate and build quality. Our structural engineers are experts at inspecting structural security of existing roof structures – all aspects will be assessed, including purlins, trusses, joists etc. Existing structural damage will be reviewed and documented, and the remaining roof lifespan discussed.

Furthermore, our structural engineers are on hand to offer tailored advice on the impact of structural integrity and measures required to strengthen the roof structure. They will support planning submissions from inception to completion and can also provide project management support, working closely with contractors and monitoring quality throughout the build process.
