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 moisture-sensitive timber, facade and frame junctions for inspection.
What the drawing needs to explain
Create a defect map with photographs, locations and investigation questions. Include inspection access and the intended drainage path in the repair proposal.
Allow for later maintenance
Use the defect map for later checks. Compare photographs of the same locations so changes are not assessed from memory alone.
Which trade-off matters?
Completely concealing a junction may look attractive but make later inspection harder. Compare a closed finish with a solution keeping vulnerable points accessible.
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.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
