Expert Flat Roofing Specialists in St Austell, Cornwall

When it comes to flat roofing, the technology has come a long way from the old 'pour and roll' felt of the past. If you're looking for a roof that can truly stand up to the Cornish elements, GRP (Glass Reinforced Plastic) is often the way to go. It’s a seamless, cold-applied fibreglass system that’s incredibly tough; you can even walk on it without causing damage, making it perfect for balconies or frequently accessed areas. It creates a completely waterproof 'envelope' over your home, meaning no joints and no leaks.

Alternatively, many of my customers across the Roseland Peninsula and St Blazey prefer EPDM rubber roofing. It’s a high-performance synthetic membrane that’s famous for its flexibility. Because it doesn't crack or rot under UV light, it can easily last over 50 years. I often recommend EPDM for larger residential extensions or garage roof replacements because it handles the natural expansion and contraction of a building beautifully. Not sure which one is right for your property? I can walk you through the pros and cons of each, ensuring you get a solution that fits your budget and your home's specific needs.

Have you noticed 'ponding'—those stubborn puddles of water that refuse to drain away? This is a common issue in St Austell and is usually caused by a lack of proper 'falls' on the roof. If water sits for too long, it eventually finds a way through. I don't just patch up the symptoms; I look for the root cause. Sometimes this involves installing new firrings—tapered strips of timber—to create a slight slope that directs water straight into your gutters.

From replacing failed lead flashing to repairing cracked felt or fixing leaky conservatory roofs, I handle all aspects of flat roof maintenance. I also offer advanced drone roof surveys for those hard-to-reach areas, providing high-resolution images so you can see exactly what the problem is without the need for expensive scaffolding. It’s a safe, quick, and cost-effective way to get a clear picture of your roof's condition. If you've spotted a leak after a heavy downpour, don't wait for it to get worse. Reach out on 01392 542323 and let's get it sorted before it causes structural damage to your timbers.

Why choose a local sole trader over a large roofing company? It comes down to trust and accountability. When you hire Devon and Cornwall Roofing, you aren't just another job number on a spreadsheet. I live and work right here in Cornwall, covering everything from Par and Polgooth to Roche and beyond. Because my reputation depends on my workmanship, I never cut corners. I use premium waterproof membranes and ensure every kerb and drip detail is fitted perfectly to keep the damp out.

I am also fully covered by Public Liability Insurance, giving you complete peace of mind while I'm on your property. Whether it's a small porch repair or a full warm roof construction for a conservatory, I turn up when I say I will and leave the site clean and tidy. You'll get a fair, transparent price with no hidden extras. If you're looking for a roofer who understands the unique challenges of our coastal climate and treats your home with respect, I’m here to help.

I get asked a lot of questions by homeowners in St Austell, so here are a few things you might be wondering about:

• How long does a new flat roof last? Modern GRP and EPDM systems are designed to last 30 to 50 years, far outperforming traditional felt.
• Can you repair a leaking flat roof or does it need replacing? It depends on the structural integrity. If the underlying timber is sound, a repair might be possible. If there's widespread rot or the membrane has failed globally, a replacement is usually safer and more cost-effective in the long run.
• What is a warm roof? This is where we place insulation above the roof joists (a 'warm deck'). It’s the best way to prevent condensation and keep your extension or conservatory much warmer in the winter.
• How much does a flat roof cost in Cornwall? Every job is unique based on size and materials. I provide free, no-obligation quotes so you know exactly what the investment will be.
