Expert Felt Roof Repairs in Warlingham & Surrounding Areas

If you notice water pooling on your flat roof, or "ponding," it is often a sign that the structure is dipping or the drainage is blocked. Look out for cracks in the felt, bubbles (which suggest trapped moisture), or internal damp patches on your ceiling. If the felt looks brittle or the silver reflective paint has worn away, the UV rays may have damaged the surface. Catching these issues early with a quick patch can save you the cost of a full replacement later.

Torch-on felt is one of the most reliable ways to waterproof a flat roof. It involves melting three layers of bitumen-modified felt together to create a thick, tough, and waterproof skin. It is much more durable than the old "pour and roll" methods used decades ago. For homeowners in Ramsden and the wider Bromley area, it offers a great balance between cost and a long lifespan, usually lasting 20 years or more if looked after properly.

Finding the exact spot of water ingress on a flat roof can be tricky because water often travels between the layers before showing up on your ceiling. We use a combination of visual inspections and physical tests to find the entry point. We check the "upstands"—where the roof meets the wall—and the joints around any pipes or skylights, as these are the most common places for a leak to start.

Regular maintenance is the best way to avoid expensive roofing contractors Bromley bills. We recommend checking your flat roof at least twice a year. This involves clearing away leaves and debris that block gutters, checking that the chippings or reflective coating are still covering the felt, and making sure no moss is growing in the corners. Keeping the surface clean prevents water from sitting on the felt for too long.

If the rest of the roof is in good condition, we can often carry out a professional patch repair. This involves cleaning the damaged area and applying a new piece of high-performance felt or a liquid waterproofing membrane. However, if the timber decking underneath has started to rot because of water ingress, a patch will only be a temporary fix. We will always give you an honest assessment of whether a repair is a sensible long-term investment for your home.
