Waterproofing for commercial roofs
Seamless renovation of larger flat roofs, based on inspection, repair and a complete project-specific system structure.
PolyShield performs this
Waterproofing and roof renovation
A watertight, maintainable building envelope with less chance of leakage and consequential damage.
- 01Inspect roof structure, moisture and details
- 02Cleaning and repairing weak areas
- 03Apply primer and detail reinforcement
- 04Waterproof membrane delivered in a controlled manner
From damage picture to solution
Problem, cause and effect first visible.
- UV and weather loads
- Movement of seams and connections
- Overdue maintenance or previous emergency repairs
Moisture can damage insulation, interior, installations and business processes.
A project-specific renovation of the substrate, details, primer and continuous membrane.
Business benefits
The value is not just in the new layer.
Lifespan
Maintain a technically suitable roof structure and postpone replacement.
Continuity
Organize renovation per work area around the use of the building.
Risk management
Include critical details before consequential damage occurs.
Maintenance
Create an inspectable and locally recoverable system route.
RISK OF DELAY
Delay can allow local defects to progress to wet insulation, larger repair zones and damage under the roof.
First have the size, cause, accessibility and desired planning assessed. We then compare repair, renovation and, where necessary, replacement without selling a standard solution in advance.

01 / Location confidentialPlanned roof renovation of school buildingApproximately 700 m² of outdated bituminous roofing with strong crackle formation, systematically renovated with primer, reinforced details and two layers of white 2K polyurea.

02 / MiddelburgEmergency repair of production roof with 2K polyureaApproximately 150 m² of a commercial roof with multiple leaks has been purposefully renovated. The urgent system approach protects the valuable production equipment under the roof against further water damage.

03 / THE HAGUELocal 2K polyurea roof renovationOp een bedrijfsdak van circa 350 m² zijn meerdere lekkages doelgericht verholpen. De geselecteerde zones zijn gereinigd en vervolgens met primer, geotextiel en een vloeibare 2K-waterdichting behandeld.

Business applications with a clear technical question.
- Business premises and logistics
- Real estate portfolios and homeowners' associations
- Contractors and housing associations
System approach
Assess roof structure and moisture condition
Repair details, seams and defects
Apply primer and targeted reinforcement
White, UV-resistant membrane in a controlled manner
Application boundaries
Assess first.
Only then specify.
- Clean wet insulation first
- First repair loose roofing
- Assess puddle formation and slope on a project-specific basis
Control profile
The division is broader than the application.
PolyShield assesses preparation, implementation and delivery as one coherent technical scope.
- 01Roof structure and moisture
- 02Details and drainage
- 03Adhesion and weather window
Can be processed quickly where responsible
Less downtime starts with the right system choice.
Where technically appropriate, PolyShield works with fast-reacting primers, two-component membranes and fast protective layers. The benefit lies not only in curing, but in a work plan in which preparation, recoating times and recommissioning are aligned in advance.
- 01
Fast-reacting 2K membranes where the surface and conditions permit
- 02
Fast drying primers to reduce waiting time between preparation and membrane
- 03
Phased implementation per roof zone so that the building remains usable
Technical roof coating
From roof condition to a planned renovation strategy.
Roof coating is a renovation method, not a way to hide wet insulation or loose roofing membranes. The existing structure must be sufficiently stable, dry and adhesive and critical details must remain permanently repairable.
With a promising structure, preservation can limit demolition, waste and business disruption. The quotation then describes not only square meters, but also preparation, primer, details, consumption, work zones and delivery control.
Business scenarios
Where this route can add value.
Aged bitumen
Stable roofing membranes with repairable seams, bubbles, edges and penetrations.
Concrete roofs
Mineral substrates with sufficient strength, appropriate slope and repairable cracks.
Local leakage zones
Targeted renovation when leakage route and boundaries can be technically determined.
Complete roof renovation
Planned lifespan extension with one controllable membrane structure.
Renovate or intervene first?
Three outcomes after the first roof assessment.
Liquid renovation
The roof structure is stable, sufficiently dry and the details can be technically repaired. Trial adhesion and system selection can follow.
Restore locally first
Bad areas, seams, drains or details are replaced or repaired before a coherent membrane layer is applied.
Further investigation or replacement
Wet insulation, large-scale detachment, structural damage or irreparable details make direct coating irresponsible.
Proof before promise
What should be visible in a commercial roof quotation.
- 01Existing roof structure and assessed zones
- 02Preparation, repairs and primer route
- 03Detailed approach for edges, drains and penetrations
- 04Membrane variant, consumption and layer structure
- 05Working window, weather limits and phasing
- 06Photo, material and delivery registration
Relevant premium technology
Cold applied 2K polyurea as a complete system direction.
An elastic 2K polyurea membrane can be assessed for this application. Suitability does not follow from the product name, but from the substrate, primer, details, load and the demonstrable system variant.

System direction
Primer, repair, main coat, detailing, anti-slip or finish are chosen as a coherent structure.
