Flat Roofing in Chertsey, Surrey

Have you ever looked out of an upstairs window after it's rained and seen big pools of water sitting on your flat roof? In the trade, we call that 'ponding,' and if it stays there for more than 48 hours, it's a sign that your roof isn't draining properly. Over time, that weight and moisture can cause traditional bitumen felt to crack or blister, eventually leading to a leak inside your home. Most homeowners we speak to tell us they've been 'patching it up' for years, but eventually, the old materials just give up. We specialise in identifying these weak points early—checking the upstands and abutments where the roof meets the wall—to stop a small problem from becoming a costly interior repair job.

If you're looking for a 'fit and forget' solution, EPDM rubber roofing is often our top recommendation. It's a single-ply membrane that we lay in one big sheet, which means there are virtually no joints for water to sneak through. What's really clever about EPDM is its flexibility; it stretches and moves with your building as the temperature changes, so it won't crack during a Surrey heatwave or a freezing winter night. It's got an incredible life expectancy of over 50 years, making it one of the most cost-effective ways to protect your property in the long run. Plus, it's environmentally friendly and looks great with a neat, matte black finish.

For those who want a roof they can literally walk on, GRP fibreglass is the way to go. It’s a popular choice for balconies or areas where you might need to pop a ladder for window cleaning. We apply a liquid resin over a glass fibre mat, which then cures into a single, seamless, and incredibly tough skin. There are no seams, no joints, and no weak spots. We finish it off with a high-quality topcoat in a colour of your choice—usually a classic grey—that looks sharp and modern. Because it's cold-applied, there's no need for hot coals or torches on your roof, giving you extra peace of mind while we work.

Don't confuse modern torch-on felt with the thin, papery stuff used decades ago. Today’s high-performance elastomeric felt is a completely different beast. It's thick, durable, and reinforced with polyester to prevent the blistering and cracking that gave old flat roofs a bad name. It’s still a very popular and cost-effective choice for garages, sheds, and smaller extensions. We use a three-layer system to ensure your roof is watertight and robust. If you're on a budget but don't want to compromise on quality, a modern felt system installed by a professional team like HomeGuard Roofing Ltd is a fantastic option.
