Start with the building
Describe livestock, storage, machinery access and interior conditions where relevant. A roof over an open shelter differs from an enclosed occupied building.
Plan the work
Clarify roof and wall interfaces, condensation concerns, drainage and any planned change of use with the responsible designer.
Prepare an enquiry
Include the project location, building type, known roof material, available reports and the decision you need help with. Share photographs only where you have permission, and avoid unnecessary personal information.
