Flat Roofing in Steyning, West Sussex

Have you noticed water sitting on your flat roof days after the rain has stopped? That's what we call 'ponding,' and it's one of the biggest red flags for homeowners in Steyning. When water can't drain away, it puts immense pressure on the structure and can lead to leaks through the substrate. Most people we talk to only notice a problem when a damp patch appears on the ceiling, but by then, the timber underneath might already be at risk. Whether it's blistering felt or cracked upstands, we've seen it all. We'll pop over, take a proper look, and tell you exactly what's going on without any confusing jargon or pushy sales tactics.

If you want a roof that's practically bulletproof, GRP fibreglass is the way to go. Think of it like a boat hull turned upside down—it's completely seamless, meaning there are no joints or weak points for water to sneak through. We've installed countless GRP roofs across West Sussex, and they're particularly popular for balconies and extensions because they look so clean and professional. The process involves laying a specialist resin and glass fibre matting over new OSB3 boards, finished with a durable topcoat. It's incredibly tough, and because it's cold-applied, there's no need for open flames on your property. It’s a fit-and-forget solution that can easily last 30 years or more.

Imagine a single sheet of high-performance rubber tailored to fit your roof perfectly. That's EPDM. It's one of the most flexible materials we work with, which is great because it expands and contracts with the Horsham seasons without cracking or tearing. We often recommend EPDM for residential flat roofs because it has a staggering life expectancy of over 50 years. It’s highly resistant to UV rays and doesn't support moss growth, which is a massive plus if your home is near trees. Because it’s a single-ply system, the installation is often quicker than other methods, saving you time and money while giving you a roof that’s built to outlast almost everything else.

Don't let the word 'felt' put you off—modern torch-on systems are a world away from the old bitumen roofs of the 70s. We use high-performance elastomeric membranes that are reinforced with polyester for extra strength and flexibility. It’s a fantastic, cost-effective choice for garages and outbuildings where you want reliable protection without a massive price tag. We apply multiple layers to ensure a thick, waterproof barrier that can handle the West Sussex rain. Our team is fully insured and highly trained in the safe use of torches, ensuring the job is done safely and to the highest standard of British Building Regulations.
