Complete Roofing Kits FAQs


Can these kits be applied in cold or damp conditions?

GRP roofing products are best applied in dry, mild conditions. Application in cold or damp weather can interfere with curing, leading to poor adhesion or surface defects. It is recommended to apply GRP roofing kits at temperatures above 5°C and avoid periods of rain. If unavoidable, accelerators or cold weather additives may be needed, though their compatibility should be checked with technical support.

How long does a typical GRP roof last?

A professionally applied GRP roof can last over 20 years with minimal upkeep. The durability stems from its seamless nature and resistance to weather, UV, and chemical damage. However, longevity also depends on correct installation, roof design, and environmental exposure. Routine checks for wear or damage will help extend the lifespan of the roof system.

Are these kits suitable for DIY use?

While the kits are designed for convenience, applying GRP roofing requires technical skill and careful preparation. DIY users with prior roofing experience may achieve solid results, but novices may find it challenging. Professional installation is recommended for larger areas, complex layouts, or where long-term guarantees are expected.

What surface types can GRP Roofing Kits be applied to?

GRP Roofing Kits are suitable for timber deck substrates such as OSB3 or marine plywood, which provide the correct bonding surface. Surfaces must be clean, dry, and structurally sound before application. These kits are not intended for direct use on metal, felt, asphalt, or concrete without specific preparation and compatible primers.

Do I need additional tools beyond what’s in the kit?

The kits are supplied with core application tools such as rollers and mixing buckets. However, additional items like gloves, protective eyewear, dust sheets, and a suitable respirator may be necessary depending on the scale of the project and working environment. Always review the kit contents and safety guidelines before starting work.
