What this job involves
Plan treatment for an accessible roof after identifying the water-entry route.
Assessment before agreeing the work
Review roof material, drainage, penetrations, joints and safe access.
Scope to confirm in the quotation
Agree compatible preparation and system details with weather and curing allowances.
How the cost is assessed
Water marks do not identify the source by themselves. A waterproofing assessment considers plumbing, joints, surface falls, membrane condition and how water enters the area. Discuss investigation and testing before deciding whether a local repair or a broader system replacement is appropriate.
- Likely water-entry route and affected area
- Access to the substrate and removal of existing finishes
- Compatible membrane or sealant system and detailing
- Drying, curing, testing and reinstatement requirements
The final scope and price depend on the site assessment, quantities, chosen materials and agreed exclusions. Ask for an itemised quotation rather than assuming a standard rate covers every condition.
Before the site visit
- Record when the water appears and which adjoining areas are affected.
- Photograph outlets, joints, corners and the visible damage.
- Share previous repair records and any available leak-test findings.
Confirm access, ownership and building-management requirements before opening up shared or external elements. Waterproofing does not replace plumbing repair or structural assessment where those are the source. Agree the test method and responsibility for reinstatement in writing.
Check the completed work
Review treated details, drainage condition and the agreed test or inspection findings.
Agree which records, material details and follow-up items will be handed over. Record any area outside the agreed scope so it is clear what has been inspected and what still needs attention.
