The Advantages of a Roof Overlay 19th May 2021

Is Your Roof Suitable for a Roof Overlay?

Depending on the condition of your current Roof, a Roof Overlay can provide you with the ability to reduce budgetary expenditure compared to potentially costly replacement works. So, what are the key characteristics of a Roof structure that is suitable for a Roof Overlay?

Most Commercial and Industrial Roofing spaces will be suitable for a Liquid Plastic Roof Overlay, providing the existing insulation and structure are in good condition. Core samples would be required to determine the condition of these Roofing elements, and providing that insulation is dry and not increasing U Values as per UK Building Regulations, a Roof Overlay would be possible. If insulation is damp, a replacement should be considered. Our specialists recommend booking a Condition Survey to determine this before instructing any works.

The following systems are eligible for Roof Overlays:

• Flat Roofs
• Metal Roofs
• Cement fibre Roofs
• Concrete surfaces

How Are Roofing Overlays Built Up?

1. Existing Roof
2. Primer existing surface
3. Primer existing surface using spray-applied primer
4. Apply PU spray adhesive
5. New thermal insulation
6. Adhered membrane
