Flat roof renovation.
From the cause to the finished work.
For houses and apartment buildings in Ljubljana and central Slovenia. A ceiling stain shows the consequence; the renovation scope depends on the cause of the leak, the condition of the layers and drainage.

What we check when a flat roof leaks
A stain inside is not necessarily directly beneath the point where water enters. We inspect visible waterproofing, outlets, roof edges and penetrations, and consider the rainfall conditions in which the problem occurs. If hidden layers cannot be assessed, we agree any additional investigations or opening-up needed before quoting. Photographs provide a starting point for the first discussion.
- Visible damage and previous repairs
- Standing water, outlets, parapets and penetrations
- Substrate condition, known layers and roof access
A local repair or complete renovation?
A local repair may be appropriate where damage is limited and the rest of the roof is in suitable condition. Repeated leaks, extensive damage or moisture within the build-up require a wider assessment. Adding new waterproofing over existing layers is not an automatic solution: the substrate, moisture, material compatibility and additional structural load must be checked.
What a renovation quote includes
The quote defines substrate preparation, removal and disposal, the proposed roof build-up, drainage and sheet-metal details. Access, building protection and excluded work are also identified. For hidden damage, we agree how findings will be documented and additional work approved before it is carried out.
Roof work on an occupied building
Before work starts, we agree the phases, temporary weather protection and building access. Opening and closing individual roof sections is adapted to the agreed solution and weather. At handover, we inspect the completed work and agreed documentation and explain maintenance of outlets and roof details.
Frequently asked questions
Must all old layers be removed?
Roof age alone cannot determine this. It depends on condition, moisture, load-bearing capacity and material compatibility. The removal scope is defined after assessment.
Can the roof be renovated while the building remains in use?
The sequence can be adapted to building use. Weather protection, access and work phases must be defined before work begins.
Is a coating over the existing waterproofing enough?
Only if that intervention is suitable for the assessed condition and chosen system. A coating does not automatically resolve moisture within layers, an unsuitable substrate or inadequate drainage. The decision follows an assessment.
What should I send for a renovation quote?
The location, approximate area and age of the roof, a problem description and photographs of the roof and damage. State when leaks occur and what has already been repaired. Attach any plans or bill of quantities.
