Flat Roofing in Warrington, Warrington

Why does traditional felt seem to fail so often? In our experience, it simply can’t handle the expansion and contraction caused by our changing temperatures. It gets brittle in the frost, bubbles in the summer sun, and eventually, the seams just give up. If you’re noticing 'ponding'—where water sits in deep puddles instead of draining away—your roof is likely sagging under the weight, which only speeds up the damage. We specialise in replacing these outdated materials with seamless GRP fibreglass and flexible EPDM rubber. These aren't just minor upgrades; they are complete game-changers for garages, dormers, and kitchen extensions. Imagine never having to worry about a leak during a winter gale again. Sounds good, doesn't it?

If you want a roof you can practically walk on, GRP (Glass Reinforced Plastic) is likely your best bet. It’s essentially a liquid-applied resin that cures into a single, solid sheet. Because there are no seams or joins, there’s nowhere for water to get in. We see a lot of this in Birchwood and Appleton, especially on balconies or extensions where homeowners want a clean, modern look. We start by stripping your old roof back to the rafters and installing fresh, high-quality OSB3 boards. Then, we apply the laminate and finish it with a durable topcoat in a colour of your choice. It looks smart, it’s incredibly tough, and it’s completely fire-retardant, making it a solid investment for any Warrington property.

For many of our customers in Lymm and Culcheth, EPDM rubber is the go-to choice. It’s a high-performance synthetic membrane that’s incredibly flexible—it can stretch and move with your building without cracking. Think of it like a giant, waterproof glove for your roof. One of the best things about EPDM is its longevity; these systems are known to last well over 30 years with very little maintenance. Because it usually comes in large, single-ply sheets, we can often cover an entire garage or small extension in one piece. No joins means no weak spots. It’s also highly resistant to UV rays, so it won’t perish or degrade over time like the old bitumen-based products did.

Is your extension or conservatory always a bit chilly in the winter? It might be because your current flat roof is a 'cold roof' with little to no insulation. When we carry out a flat roof replacement in Warrington, we often recommend a 'warm roof' installation. This involves placing high-quality insulation boards on top of the structural deck before the waterproof membrane goes on. This simple change traps heat inside your home, making the room below much more comfortable all year round. It’s a brilliant way to improve your home’s energy efficiency while you’re already having work done. Most of our clients find that the savings on their heating bills over time help the new roof pay for itself.
