🧾 GRP Roofing Kits Price Comparison by Weight (Excl. VAT)
| Kit Weight | Typical Price Range per m² | Average Price per m² | Best Value at Larger Sizes? |
|---|---|---|---|
| 300g | £11.58 – £26.79 | £20.45 | No (smaller kits are cheaper per m²) |
| 450g | £10.38 – £18.33 | £14.13 | Yes |
| 600g | £16.12 – £21.64 | £17.81 | Yes |
📊 Key Insights
450g kits offer the lowest average cost per m², making them the most economical option overall.
600g kits, while slightly more expensive than 450g, provide increased durability and strength and still benefit from price efficiency at larger sizes.
300g kits are typically more expensive per m² despite being the lightest, especially in medium-size kits, which may be due to smaller packaging efficiencies + Tin sizes & rounding up
📌 Conclusion
For budget-conscious projects: Go with 450g kits, especially for larger areas (20m²+).
For enhanced strength and durability: Choose 600g kits, especially if covering 50m² or more.
300g kits are suitable for light-duty or small repairs but are not the most cost-effective option by area.
