Chimney drawings: 20 detailed principles
See how the chimney connects to the roof, floors and walls. Use the drawings to discuss your plans, understand the scope and prepare questions for an assessment.
These are principle drawings, not drawings of your property. Dimensions, support arrangements and execution details require a site assessment and, where needed, a structural design.

Compare the roof stack, internal chimney breast and complete flue route. The agreed extent determines which interfaces and finishes need assessment.

Closing the opening is only one part of a roof repair. These details distinguish the covering, substrate, insulation, moisture control and connections to existing layers.

Repairs differ for each surface. See the distinction between structural closure, substrate repairs and the final finish that needs to be agreed.
Shared parts and active flues
One visible chimney may serve several owners, homes or appliances. Record connections and ownership before defining the scope.
Surveys and access
Preparation identifies missing information about materials, access, working space and separation between occupants and the work area.
