What you can observe
After rain, parts of the roof remain wet for a long time or drains regularly become overloaded.
Problem guide · Roof and waterproofing
There is still water on my company roof
Puddle formation around drains, seams or sagging roof areas.
Problem · cause · effect
First understand what is going on.
Only then choose a system.
Why timely assessment helps
Long-term water exposure increases pressure on seams, details and existing repairs and can increase contamination and accelerated aging.
What is being technically investigated
Map the slope, drainage capacity, roof structure and moisture condition and then determine whether drainage repair, local correction or a water-loaded membrane system is appropriate.
Possible causes
The visible complaint is not always the real cause.
These causes constitute a targeted checklist, not a remote diagnosis.
Insufficient or locally lost slope
Clogged, too high or insufficient drains
Subsidence of insulation, substructure or existing roof layers
Project-specific control
Three components determine the correct next step.
The Problem Guide provides direction, but does not make an unfounded material claim. For a final system choice, we check the situation on location or based on sufficient project information.
- 01Roof structure, age and existing layers
- 02Moisture, adhesion, drainage and critical details
- 03Reachability, business risk and execution window
Value of a complete approach
Don't just recover.
Making the project manageable.
- Targeted delineation of leak routes and water-laden details
- Avoid unnecessary coating of technically unsuitable areas
- Organize drainage, repair and waterproofing as one executable scope
In-depth and evidence
From recognizable problem to verifiable project information.

Launch tool →Frequently asked questions
Answered briefly and technically honestly.
Can coating solve puddle formation?+
No. A membrane can protect water-stressed zones, but does not create a new structural slope.
Does stagnant water always have to lead directly to leakage?+
Not always, but long-term loading increases the importance of intact seams, drains and details.
Can Roof Intelligence determine the cause?+
The tool helps record surface and risk areas; a definitive cause requires project inspection.
Short route to implementation
Check with two questions whether the project fits.
The project fit prevents an unnecessarily long application. Your problem situation is selected in advance and known data then travels automatically.
