Why a basic square meter price is misleading
Two roofs of 80 m² can differ greatly. One roof has an open main surface and few details; the other contains many penetrations, upstands, installations, bladders and difficult-to-reach areas.
A reliable budget separates the main surface, detail meters, repairs, preparation, equipment and chosen layer structure.
The most important cost factors
Cleaning and mechanical preparation determine adhesion. Primer choice, detailed reinforcement, material consumption and number of layers also influence labor and materials.
Accessibility, fall protection, parking, supply and weather planning may require additional organization at private locations.
- Net roof area
- Number and type of details
- Substrate condition
- Moisture and repairs
- Primer and membrane consumption
- Accessibility and safety
- Execution window
Minimum size and project quality
PolyShield focuses the private coating route on roofs from approximately 50 m². This allows preparation, quality control and mobilization to be organized within an appropriate project scope.
After a roof measurement and photo intake, an initial scope can be determined. Final quantities and suitability will only be confirmed after sufficient project information has been provided.
This explanation is general and does not constitute project-specific system advice. Subsurface investigation, tax and official system documentation remain decisive.
