Roof and structure demolition work" refers to the process of systematically dismantling and removing
the roof components and structural elements of a building, typically using a combination of manual
labor, power tools, and heavy machinery, while adhering to safety protocols to safely bring down the
entire structure and clear the site for redevelopment; this may include tasks like removing roof tiles,
beams, rafters, walls, floors, and other structural supports, often requiring the identification and
removal of hazardous materials like asbestos prior to demolition.

Site preparation: Securing the perimeter with fencing, removing utilities, identifying and managing hazardous materials
like asbestos.
Structural assessment: Analyzing the building's structural integrity to determine the safest demolition method.
Roof removal: Disassembling roof components like tiles, sheathing, and framing using hand tools or specialized
machinery.
Structural dismantling: Cutting and removing load-bearing walls, beams, columns, and floor joists using power tools like saws,
cutting torches, or demolition hammers.
Debris management: Loading and hauling away demolished materials to designated disposal areas.
Safety measures: Wearing appropriate personal protective equipment (PPE) like hard hats, safety glasses, gloves,
respirators, and high-visibility clothing, following safety protocols and maintaining a safe work zone.
Methods of roof and structure demolition:
Manual demolition: Using hand tools like sledgehammers, crowbars, and axes for smaller structures.
Mechanical demolition: Employing heavy machinery like excavators, cranes with wrecking balls, and specialized demolition
attachments.
Controlled demolition: Utilizing explosives in carefully planned scenarios for large structures, requiring specialized expertise.
