Flat Roofing in London, Westminster

Ever looked out of an upstairs window after it's rained and seen a mini-lake sitting on your extension? That's what we call 'ponding' water, and it's usually a sign that your roof isn't draining quite as it should. Over time, that weight and moisture can lead to 'blistering' in old felt or even cracks in the substrate. Most homeowners we speak to in Westminster find that their old bitumen roofs are simply reaching the end of their natural life. We'll come out, take a proper look at your upstands and abutments, and give you a straight-talking assessment of what needs doing. We focus on fixing the root cause, not just patching the symptoms.

If you're looking for something that you can essentially 'fit and forget,' EPDM rubber roofing is often the way to go. It’s a single-ply membrane that's incredibly flexible—it doesn't mind the heat of summer or the freezing London winters. Because it’s laid in large sheets, there are very few seams, which is where most leaks start. We often recommend this for residential extensions because it’s known to last upwards of 50 years. It’s tough, eco-friendly, and handles the UK's high rainfall without breaking a sweat. It’s an ideal choice for anyone wanting a long-term, low-maintenance solution.

Need a roof that looks as good as it performs? GRP fibreglass is a fantastic choice, especially if you have a balcony or a roof terrace in the heart of Westminster. It creates a completely seamless, stone-hard finish that's impossible for water to penetrate. We apply it as a liquid that cures into a solid, waterproof barrier. It’s a bit like the hull of a boat—if it can keep a ship afloat, it can definitely keep your kitchen extension dry. Plus, you can choose different colours to match your property's aesthetic perfectly, making it as stylish as it is functional.

Don't let the word 'felt' put you off. The modern torch-on felt systems we use today are worlds apart from the thin, brittle stuff used thirty years ago. We use high-performance elastomeric membranes that are reinforced with polyester, making them incredibly strong and resilient. It’s often the most cost-effective solution for garages, sheds, or outbuildings. We ensure every drip edge and kerb is finished perfectly, so you get a professional, watertight result that won't break the bank. It's a tried and tested method that, when installed by experts like us, offers brilliant protection for decades.
