About Fire Rated Roofs & buying advice

Shop fire-rated GRP roofing kits, fire-rated fibreglass roofing kits and upgraded flat roofing kits for projects where fire performance or building control requirements need to be considered.

Compare the specification

Other GRP roofing systems for the same project

Compare the roof duty and specification rather than hopping between brands. The correct route depends on the roof area, intended use, substrate and any fire-performance requirement.

Coverage transparency

Measure the roof, then choose supplied coverage

  1. Measure the finished roof area before ordering.
  2. Choose a kit whose stated supplied coverage meets or exceeds that area.
  3. Check the exact kit contents and whether trims, primer, deck materials or tools are included.
Is this right for my roof?

Check the substrate before laminating

A new GRP roof needs a dry, stable and compatible deck installed to the chosen system guidance. Do not assume standard GRP can be laminated directly onto an unknown, damp or failed existing roof surface.

Buying guide

Choose Fire Rated GRP Roofing Kits for installing a GRP flat roof where fire-rated roof performance is required.

Good choice when

  • Use this category for installing a GRP flat roof where fire-rated roof performance is required.
  • Use it when the surface is new OSB3 or suitable timber roof deck.
  • Use it when the measurements, preparation work and related accessories have been checked.

Consider another route when

  • Do not use this category when the existing roof only needs a quick repair, coating or overlay rather than a new GRP system.
  • Do not use it when the roof is unsafe or unsuitable without preparation.
  • Do not use it as a shortcut if another CRS system is a better fit.

Next step: Choose the fire-rated kit weight, check the roof size and match it with the correct trims.

Fire Rated GRP Roofing Kits For Flat Roof Projects

Fire-rated GRP roofing kits are designed for flat roof projects where upgraded fire performance may be required. They are useful where building control, project specification or roof location means fire performance needs to be considered before choosing a standard GRP system.

Always check the requirements for your project before ordering, especially for extensions, boundary conditions and controlled works. Fire performance requirements can depend on the building, location and specification.

Fire Rated vs Standard GRP Roofing Kits

Standard GRP roofing kits are suitable for many domestic flat roofs. Fire-rated GRP kits are used where an upgraded specification is required or where the project calls for improved fire performance.

Frequently asked questions

What is a fire-rated GRP roofing kit?

A fire-rated GRP roofing kit is a fibreglass flat roof system designed for projects where upgraded fire performance may be required.

When do I need a fire-rated GRP kit?

You may need a fire-rated kit where building control, project specification or roof location requires upgraded fire performance. Always check the requirements for your project.

Are fire-rated GRP kits suitable for extensions?

They can be suitable where an extension roof requires an upgraded fire performance specification, but requirements should be checked before ordering.

Is fire-rated GRP the same as standard GRP?

No. Fire-rated GRP kits are intended for projects needing upgraded fire performance, while standard GRP kits are used for general flat roofing projects.

Can CRS confirm my building control requirements?

CRS can help you choose products, but local building control or your project specifier should confirm the exact fire performance requirements for your roof.
