Fibreglass Roofing in Sevenoaks , Kent

For most residential extensions and garages in Snodland, GRP fibreglass is an excellent investment. Its main advantage is that it has no seams. Because the resin and glass matting are laminated together on-site, there are no joints or welds where water can eventually track through. It is also incredibly tough. While some materials can be easily punctured, a properly installed GRP roof is impact-resistant and can withstand the typical debris or foot traffic associated with domestic maintenance.

When installed correctly by an experienced roofer like Levi King, a GRP flat roof can easily last 25 to 30 years, often outperforming the building it covers. It doesn’t suffer from the same UV degradation as old-fashioned felt. In Kent’s variable climate—where we see baking summer heat followed by heavy winter frosts—the material expands and contracts without splitting. Levi makes sure the perimeter trims and leadwork are detailed correctly so the roof remains a single, leak-proof unit for decades.

Yes. One of the reasons glass reinforced plastic roofing is so popular in Snodland is its versatility. If you have a flat roof that you need to walk on, such as a balcony or a terrace, we can apply a specific non-slip grit finish to the topcoat. This makes the surface safe to walk on even when wet, without compromising the waterproofing. It is much more durable for these high-traffic areas than EPDM rubber or mineral felt.

Both are modern, reliable systems, but they suit different needs. EPDM is a flexible rubber sheet that is glued down, which is great for larger, simple spans. GRP fibreglass is a rigid, liquid-applied system that cures into a hard shell. GRP is often preferred for more complex roof shapes or where the roof needs to be aesthetically sleek, as it comes with pre-formed trims that give a very neat, architectural finish. Levi can assess your specific roof during a site visit to suggest which material fits your budget and the structure of your building.

One of the best things about fibreglass is how little you have to do once it is down. Because it doesn’t support moss growth as easily as tile or felt, a simple brush off or a quick wash with soapy water every year is usually enough to keep it looking new. Levi recommends keeping your gutters clear to prevent water from backing up, but the GRP surface itself is virtually maintenance-free. If a tile from the main house falls and hits it, the material is usually tough enough to take the impact without cracking.

In almost every case, a new GRP roof requires a fresh deck of OSB3 moisture-resistant boards. This provides the perfect surface for the resin to bond to. If Levi finds that your current joists are in good condition, he will simply fix the new decking over them. If there is rot from a long-term leak, he will replace the damaged timber first to make sure the structural integrity of the roof is sound before the fibreglass is applied.
