Targeted refurbishment
If the existing roof is sound and suitable, refurbishment may be possible without removing the entire build-up. We assess this during an on-site inspection.

Roof coatings
Seamless coatings and waterproofing for flat, metal and industrial roofs.
Discuss your project
Your application
Tailored to your property.
We design roof coatings and waterproofing to suit the existing roof construction. We consider the surface and its details together, including junctions, upstands and penetrations.
Typical applications
- Flat and industrial roofs
- Metal roofs
- Suitable bituminous and existing roofs
Carefully planned details
Roof edges, outlets, penetrations and junctions are included in the waterproofing design.
Protection suited to the roof
The primer, polyurea membrane and final protective coat are selected to suit the substrate and expected exposure.
System build-up & documentation
Every layer has a purpose.
The final build-up and coating thickness are specified for the roof, substrate and approved system.
-
01
Prepare the substrate
Assess the existing roof, clean and prepare the surface, and repair suitable areas.
-
02
Apply the system primer
Select the primer for the substrate and the specified waterproofing system.
-
03
Spray the polyurea membrane
Create a continuous membrane, including upstands, outlets and penetrations.
-
04
Complete the protective coat
Specify the finishing coat for weather exposure, UV protection and intended use.
ETAG 005 · ETA 16/0148
Documented waterproofing system
For Polyurea Rayston, the manufacturer's technical data sheet lists European Technical Assessment ETA 16/0148 (ETAG 005). The relevant system requirements determine the specification and application.

From assessment to application
How we create your coating system.
-
01 · Assess the property
Assess the roof construction, moisture, adhesion and drainage.
-
02 · Specify the build-up
Match preparation, primer, coating and protective coat to the property.
-
03 · Apply the coating professionally
Apply the selected system to the prepared substrate and complete the details.
-
04 · Check quality
Check and document roof junctions, coating thickness and workmanship.
Roof refurbishment
Your roof. Your questions.
The key points before we inspect your property.
01Can the existing roof remain in place?+
That depends on its condition, moisture and adhesion. We assess the existing build-up before deciding which areas can remain and which require repair or removal.
02Are junctions and penetrations included?+
Yes. Roof edges, upstands, outlets and penetrations are considered together with the roof surface when specifying the waterproofing.
03What determines the cost?+
Roof area, access, substrate condition, preparation and the number of details determine the scope. Send us the location, approximate area and photos for an initial assessment.
04How is the work checked?+
Coating thickness, junctions and workmanship are checked and documented. Access and return to use are agreed for the specific system and project.
