What this work involves
Assess existing layers, moisture, falls and roof edges. Select a system suited to the complete assembly and intended use.
- Roof build-up and material
- Drainage and overflow
- Edges, upstands and penetrations
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Coordinate opening windows and shading with work and play areas.
What the drawing needs to explain
Show furniture, door swings and circulation on one plan. Mark a quiet workspace and the places where several people pass at once.
Allow for later maintenance
Keep service routes with the room plan. The information helps when a bedroom later needs a different arrangement or use.
Which trade-off matters?
An open living space makes contact easy but offers less separation for sound and work. Compare a fully open plan with closable zones while retaining clear routes to the kitchen and stairs.
Cost factors for this service
Costs depend on area, removal work, insulation and detailed junctions. Ask for the scope and selected specification to be described separately.
Bring this to the discussion
Photographs of the existing situation, available drawings and your requirements for flat roofs, bitumen & epdm. Identify the elements that should remain.
Questions about the work
What should I discuss before arranging flat roofs, bitumen & epdm?
An additional layer is only appropriate if the existing substrate is suitable. Assess moisture and the condition of underlying layers.
