How to Avoid Surprises

• check roof load limits and have structural reports to hand if available

• advise tradie of restricted access, low roofs, narrow stairs or weight limits in advance

• check building rules for working at height and arrange permits or method statements if needed

• clear the area of vehicles and secure pets; ensure power and water isolation can be done if required
