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.
Assess glazing divisions alongside privacy and available furniture walls.
What the drawing needs to explain
Draw fixed furniture, sightlines and opening windows together. Allow room for screening so it does not later obstruct cupboards, heaters or passages.
Allow for later maintenance
Keep window cleaning and controls accessible beside bespoke furniture. Retain drawings of removable parts so maintenance does not require unnecessary dismantling.
Which trade-off matters?
A larger glazed area can visually open the room but remove useful wall space. Compare window divisions and bespoke storage together, including curtains or other screening.
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.
