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.
Compare glazing, shading and roof openings as one part of indoor comfort.
What the drawing needs to explain
Draw one section through the kitchen, glazing and terrace. Include finished floor levels, the roof edge and shading position; separate supplier sketches do not fully show these relationships.
Allow for later maintenance
Keep glazing and rooflight maintenance instructions together. Leave outdoor surfaces accessible without having to remove permanent furniture or planting.
Which trade-off matters?
A wide garden opening takes away wall space for cupboards. Compare a fully glazed rear wall with a smaller opening and a targeted rooflight, looking at both from the same seat.
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.
