Flat Roofing in Petworth, West Sussex

Most homeowners we speak to in Petworth tell us the same story: they noticed 'ponding' water that just won't shift, or the old felt has started to crack and blister in the sun. These aren't just cosmetic issues; standing water puts immense pressure on your roof structure, and those tiny cracks are often the first sign that water is finding its way into your timber deck. We see these problems all the time across West Sussex, often caused by poor drainage or outdated materials that have simply reached the end of their life. Because we're Checkatrade and Bark approved, you don't have to take our word for it—our reputation is built on solving these exact issues with craftsmanship that lasts. We'll look at your upstands, check your abutments, and ensure your drainage is actually doing its job before we even think about suggesting a solution.

Imagine a roof that has no joints, no seams, and is tough enough to walk on. That's exactly what you get with GRP (Glass Reinforced Plastic) fibreglass. It’s becoming an incredibly popular choice for Petworth residents, especially for balconies or roofs that see a bit of foot traffic. Because it's applied as a cold liquid, it cures into a single, continuous membrane that’s practically bulletproof when it comes to leaks. We often recommend GRP for extensions and dormer windows because it looks sleek and performs brilliantly for decades. Our team is fully trained in the curing process to ensure a perfect finish every time, even in the specific coastal-influenced climate we get here in West Sussex. It’s a bit like wrapping your roof in a protective, waterproof shell that won't give you a moment's worry for years to come.

If you're looking for longevity, it’s hard to beat EPDM rubber. This single-ply membrane is famous in the industry for having a life expectancy of over 50 years. It’s incredibly flexible, meaning it doesn't crack when the temperature drops or when the house naturally settles over time. Most of our Petworth customers love it because it’s environmentally friendly and can usually be installed in one large sheet, meaning there are no weak points for water to sneak through. Whether it's a small porch or a large commercial unit in Chichester, EPDM provides a clean, modern look that requires almost zero maintenance. We’ve installed countless rubber roofs across the RH28 area, and they stand up to the wind and rain of the North Downs without breaking a sweat.

Forget the thin, leaky felt roofs of the past. Today’s high-performance torch-on felt is a completely different beast. We use multi-layer elastomeric bitumen systems that are incredibly resilient and cost-effective. These systems are perfect for garages, sheds, and outbuildings where you want a reliable, waterproof seal without the higher cost of GRP or EPDM. By using modern torching techniques, we bond the layers together to create a thick, durable barrier. It’s a great 'middle ground' option that offers fantastic value for money. We always make sure the substrate—that’s the wooden deck underneath—is in top condition before we start, because even the best felt won't last if it's laid on rotten timber. It’s all about doing the job right the first time so you don't have to call us back in six months.
