Flat Roofing in East Grinstead, West Sussex

Many homeowners we speak to in East Grinstead are dealing with the same headache: an old bitumen felt roof that's seen better days. You might have noticed 'ponding'—those stubborn puddles that sit on the roof for days after it stops raining. If that water doesn't drain away within 48 hours, it starts to put immense pressure on the structure and can lead to timber rot. Maybe you've spotted blistering or cracks in the surface where the sun has baked the old materials over the years? These are clear signs that the waterproof barrier is failing. We specialise in identifying these weak points before they turn into a major internal disaster. We'll check your upstands, the lead flashing where the roof meets the house, and the decking underneath to ensure everything is structurally sound before we even think about laying a new surface.

If you want a roof you can essentially 'fit and forget,' EPDM rubber roofing is often our top recommendation. Imagine a single, seamless sheet of high-performance rubber custom-cut to fit your roof perfectly. Because there are no joints or seams on most domestic extensions, there's nowhere for the water to get in. It's incredibly flexible, too, which means it won't crack when the temperature drops in winter or bake and split during a Surrey Hills heatwave. We've seen EPDM roofs still going strong after 50 years, making it one of the most cost-effective investments you can make for your home. It's particularly popular for extension roofs and larger outbuildings where longevity is the main priority.

Looking for something that looks as good as it performs? GRP (Glass Reinforced Plastic) fibreglass is a fantastic choice, especially for properties in more modern parts of East Grinstead or for those who want to use their flat roof as a balcony or terrace. We apply the GRP as a cold liquid that cures into a single, continuous, and completely waterproof 'shell.' There are no seams, no joints, and no weak points. It's incredibly tough—you can walk on it without fear of damage—and it comes in a range of grey finishes that look sleek and professional. Because it's cold-applied, there’s no need for hot coals or torches on your property, making it a very safe and clean installation process.

Don't confuse modern torch-on felt with the thin, papery stuff used decades ago. Today’s high-performance elastomeric felt is a different beast entirely. It’s built in three thick, reinforced layers that are 'torched' together to create a formidable barrier against the elements. We often find this is the perfect middle-ground for garage roofs or garden offices in West Sussex. It’s durable, budget-friendly, and when installed by an expert team like ours, it will easily provide a couple of decades of reliable service. We pay particular attention to the 'drip edges' and guttering interfaces to make sure every drop of rain is directed exactly where it should go.
