Flat roofs are brilliant when they’re done right and a nightmare when they’re not. Done badly, you end up with pooling water, blistered felt and leaks every winter. Done properly, with the right system for the job, a flat roof can last 25 years or more without a problem.
First 4 Contracts Ltd specialise in flat roof repair and installation across Cardiff, Newport and South Wales. Whether it’s a small garage roof, a kitchen extension, or a larger commercial property, we’ll talk you through the right system for your needs — EPDM rubber, hot melt rubber, or traditional felt — and explain the pros and cons of each in plain English.
Welsh weather is hard on flat roofs. Constant rain, wind-driven moisture and freeze-thaw cycles work away at any weak point. Our installations are designed around that — proper falls so water doesn’t sit, fully bonded membranes, well-sealed upstands and quality finishes that don’t crack at the first sign of a frost.
If your existing flat roof is leaking, blistering or coming up at the edges, give us a call. We’ll inspect for free and let you know whether a repair will do or whether it’s time to replace the whole thing.
EPDM Rubber Flat Roofs
EPDM is a single-sheet rubber membrane that’s tough, flexible and weather-resistant. It comes in one continuous piece for most domestic roofs, meaning fewer joints and far fewer places for water to get in. Properly fitted, it’ll last 25+ years and shrugs off Welsh winters easily.
Hot Melt Rubber Roofing
Hot melt is a fully-bonded, seamless system poured on-site. It’s incredibly hard-wearing and ideal where a roof has to handle foot traffic, planters, or anything else on top. A premium option that lasts decades.
Traditional Felt Flat Roofs
Modern torch-on felt has come a long way. Multi-layer felt systems, properly installed, give you a reliable, affordable flat roof with a 15–20 year lifespan. We use top-grade felt and bond it cleanly — no skimping.
Common Flat Roof Problems
Pooling water, blistered surfaces, split seams, perished felt, leaking around upstands and chimney flashings — we see them all. Often a targeted repair will buy you several more years. We’ll always be honest about whether it’s worth it.
