When a homeowner in Enfield contacted HighPoint Roofing And Building about a seriously leaking flat roof, it was clear that a straightforward repair simply wasn't going to cut it. The existing roof had deteriorated to the point where the decking beneath had been completely compromised by water ingress, leaving no option but a full replacement from the boards up. Fortunately, the customer was also able to take advantage of our 20% discount offer at the time, making it the right moment to have the work done properly and with confidence. Before any new roofing materials could go down, the team stripped the old roof back entirely and assessed the structural decking beneath. As expected, the damage was extensive — every board needed to come out and be replaced. HighPoint Roofing fitted 18mm OSB boards across the full roof area to create a solid, level substrate. Getting the decking right at this stage is critical, because no amount of quality felt or membrane work will perform as it should if the base beneath it isn't sound. This is a step that separates a professional re-roof from a patch-and-hope job. With the new decking in place, the team installed a three-layer torch-on felt system using Rose high-performance materials. This involved two layers of torch-on underlay felt applied sequentially, each one heat-bonded to create a continuous, watertight seal across the entire roof surface. The third and final layer is the mineral finish cap sheet, chosen here in a charcoal finish. Torch-on felt systems like this are among the most reliable and durable solutions available for flat roofing in the UK, particularly in areas like Enfield where roofs are exposed to the full range of British weather throughout the year. The mineral surface cap sheet provides excellent UV resistance and weatherproofing, while the charcoal finish gives the completed roof a clean, modern appearance that sits well against brickwork and renders commonly seen across EN1 and the wider Enfield area. Alongside the felt system, HighPoint Roofing also fitted new UPVC fascia edging around the perimeter of the roof. This detail is often overlooked on flat roof projects, but it plays an important role in finishing the edge neatly, protecting the felt termination point, and channelling water away from the fascia line effectively. UPVC is a practical choice in this context — it won't rot, doesn't need painting, and holds up well over time without requiring any maintenance from the homeowner. One of the most impressive aspects of this particular project was the turnaround time. Despite the full decking replacement and the three-layer felt installation, the entire job was completed in a single day. That kind of efficiency comes from experienced roofers who know exactly what they're doing and arrive fully prepared with the right materials and equipment for the scope of work. For the homeowner, it meant minimal disruption and a weathertight roof by the end of the working day. The finished result was a transformation. Where there had previously been a failing, leaking roof causing real damage to the property, there is now a professionally installed flat roof system that is fully sealed, neatly edged, and built to last. The charcoal mineral finish looks sharp and contemporary, and the UPVC fascia detail gives the whole installation a tidy, finished appearance. All work carried out by HighPoint Roofing And Building on this project is backed by a 10-year guarantee, giving the customer genuine long-term peace of mind. A quality torch-on felt flat roof, properly installed on solid decking with the right products, should perform reliably well beyond that period — but having a written guarantee in place means the homeowner is fully protected regardless.
