01

Why choose GRP for your Medway flat roof

Unlike older bitumen felt options that rely on vulnerable seams, GRP fibreglass creates a completely joint-free, waterproof membrane. This makes it an ideal choice for Chatham properties that frequently experience wind-driven rain and varied weather patterns. The system is exceptionally tough, capable of handling standing water, and provides a neat, modern finish that can be tailored with anti-slip coatings for balcony areas or high-traffic flat roofs.

02

The importance of a sound timber deck

A high-performance roof starts with the foundation. When we replace your flat roof, Levi King inspects the underlying timber structure for any signs of rot or decay. We use moisture-resistant OSB3 boards to create a solid, level deck before applying the GRP resin and glass fibre matting. This attention to detail prevents future movement and ensures your new roof remains stable, rigid, and fully weather-tight for many years to come.

03

Meeting thermal and local building standards

When replacing a flat roof in Chatham, we take care to adhere to current Building Regulations, particularly those regarding thermal performance. If a significant portion of your roof surface is being replaced, we will advise on necessary insulation upgrades to improve your home’s energy efficiency. By working directly with Levi King, you get clear, honest guidance on what is required to keep your property compliant with modern standards while maintaining its original character.

04

How do we manage installation on terraced streets

We are fully experienced in working within the distinct constraints of Medway’s urban landscape, including the steep-pitched streets and tight parking zones often found in Chatham and Rochester. We manage the logistics of every installation to minimise disruption to your neighbours while maintaining a tidy, safe site. Our process focuses on clear communication from the initial survey right through to the final application of the weather-resistant topcoat.

Fibreglass Flat Roofing Guidance

Frequently Asked Questions

Straightforward advice from Levi King on GRP fibreglass installations, deck preparation, and weather-resistant flat roof replacements across Snodland and Aylesford.

Is GRP roofing the best choice for a flat roof replacement in Snodland?

+

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.

How long will a fibreglass roof stay watertight on my home?

+

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.

Can a seamless GRP membrane be used for balconies or walkways?

+

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.

What is the difference between EPDM rubber and GRP fibreglass roofing?

+

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.

Will my new fibreglass roof require a lot of maintenance?

+

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.

Do I need to replace the timber boards before a GRP installation?

+

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.
