When a homeowner in Cricklewood noticed water aggressively making its way into their property through a failing flat roof, they knew the time had come to stop patching and start fresh. They called HighPoint Roofing And Building, and within a single working day, the old leaking roof had been stripped back and replaced with a fully specified, high-performance system designed to last for years to come.
The existing flat roof had reached the end of its serviceable life. Persistent leaking had caused enough deterioration that the decking beneath the felt had been compromised and needed to be replaced before any new covering could be fitted. This is a critical step that some roofers skip to save time, but cutting corners at this stage undermines everything that goes on top. HighPoint Roofing replaced the decking properly, giving the new roof a sound, stable base to work from.
For the new covering, the team installed a three-layer torch-on felt system using high-performance torch felt throughout. This type of system is widely regarded as one of the most reliable and durable solutions available for flat roofs in the UK. The build-up consists of two underlay layers beneath a mineral finish top sheet, applied across the full 3m by 6m area of the roof. The mineral finish top layer was chosen in charcoal, giving the completed roof a clean, professional appearance that sits neatly against the property.
Torch-on felt systems work by bonding each layer directly to the one below using heat, creating a continuous, watertight membrane without the weak points that can occur with mechanically fixed systems. When installed correctly by experienced roofers, this approach delivers exceptional resistance to the kind of wind-driven rain and temperature fluctuation that flat roofs in London face throughout the year. It is precisely the sort of specification you want when water ingress has already caused problems.
Alongside the new felt system, HighPoint Roofing fitted new lead flashing along the rear wall. Lead flashing is the critical junction between the flat roof surface and any adjoining brickwork or upstand, and it is one of the most common sources of leaks when it fails or was never fitted correctly in the first place. Having new lead flashing installed as part of this re-roof ensures that the entire waterproofing detail is renewed, not just the field of the roof itself. New guttering was also installed at the same time, ensuring that rainwater is collected and directed away from the building efficiently.
Ventilation was improved as part of the project, which is an important consideration on flat roofs where trapped moisture within the roof structure can cause condensation damage over time. Insulation was also fitted, improving the thermal performance of the roof and helping the homeowner benefit from better energy retention going forward.
While the roofing team was on site, they also replaced the uPVC fascias, completing the roofline with fresh, low-maintenance boards that complement the new guttering system. These finishing details make a real visual difference and mean the homeowner has a completely renewed roofline, not just a patched-up flat roof.
The transformation from start to finish was described as total. What had been a source of ongoing stress and water damage was resolved in a single day, leaving the property with a watertight, properly insulated and well-finished flat roof that carries a 10-year guarantee. No building regulations approval was required for this re-roof, making the process straightforward for the customer from enquiry through to completion.
