What this work involves
Survey covering, junctions and the structure beneath. A leak may appear away from its source. Coordinate maintenance with assessment of insulation and moisture conditions.
- Covering and junction survey
- Substrate and moisture
- Insulation and build-up
- Drainage and penetrations
- Safe access and temporary protection
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Detail internal frame junctions alongside envelope choices.
What the drawing needs to explain
Draw one bespoke junction at a large scale with every adjoining finish layer. Identify who takes final dimensions and which substrate must be ready for that measurement.
Allow for later maintenance
Keep finishing products and care instructions for each surface. Record how panels or fittings can be reached without damaging adjoining bespoke work.
Which trade-off matters?
A minimal joint or concealed fixing may need extra coordination. Compare the intended appearance with tolerances, maintenance and replaceability before treating a detail as straightforward.
Cost factors for this service
Area, roof shape, material, access and substrate repairs determine the budget.
Bring this to the discussion
Photographs, known leaks, approximate area and earlier work.
Questions about the work
Can new covering go over the existing layer?
It depends on material, condition, adhesion, moisture and the complete build-up. Have the roof assessed first.
