What you can observe
Rust formation, open connections or leakage around overlap and attachment.
Problem guide · Roof and waterproofing
My metal roof leaks or corrodes
Corrosion, seams, fasteners or outdated coating.
Problem · cause · effect
First understand what is going on.
Only then choose a system.
Why timely assessment helps
Plaataantasting en lekkage kunnen zich onder een nieuwe coating blijven ontwikkelen wanneer voorbereiding onvoldoende is.
What is being technically investigated
Determine corrosion degree, existing layer, cleaning, detail restoration and suitable elastic protective layer as one system scope
Possible causes
The visible complaint is not always the real cause.
These causes constitute a targeted checklist, not a remote diagnosis.
Aging or local defects in existing roof layers
Vulnerable seams, drains, curbs or penetrations
Moisture, contamination or an unsuitable previous repair
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.
- Determine cause and treatment limit before selecting material
- Retain usable existing roof parts where responsible
- Plan work areas, weather and business continuity in advance
In-depth and evidence
From recognizable problem to verifiable project information.
Frequently asked questions
Answered briefly and technically honestly.
Can PolyShield immediately recommend a system?+
First, the cause, substrate, size and project context are checked. An appropriate system direction can then be substantiated.
What information helps with an initial assessment?+
Project address, general scope, some overview and detailed photos, building use and desired planning are usually sufficient to get started.
Do I have to re-enter all the data?+
No. Choices from the Problem Guide are automatically taken to the next tool and project request.
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.
