Weatherproofing Advisors were recently appointed to refurbish the ageing roof of Cadent Gas’ PT&E Building in Manchester. The existing single-ply membrane roof had reached the end of its service life, with visible signs of wear and persistent drainage issues causing standing water and water ingress that posed risks to the building and its contents.
Our team was brought in to develop a cost-effective, long-lasting solution that would address these problems and extend the roof’s lifespan. The plan involved removing the ineffective kerb edge detail on the southern side of the roof to allow water to drain freely. This eliminated the need for expensive tapered insulation and improved overall drainage performance.
The works included the full removal of the old roof system and the installation of a new waterproof covering, along with a new drip edge detail and PVC guttering. A secure compound and mechanical hoist were set up on site to improve safety and reduce manual handling during the job.
The result was a clean, watertight finish that resolved long-standing issues and left the building protected for years to come.
Weatherproofing Advisors were successfully appointed to refurbish the ageing roof at Cadent Gas' PT&E Building, resolving drainage issues and installing a durable, watertight solution.
Weatherproofing Advisors were approached to evaluate and propose a cost-effective solution for a single ply membrane roof that had reached the end of its serviceable life.
The existing roof was in poor condition, with visible signs of fatigue and widespread issues, including the accumulation of significant amounts of standing water and ongoing water ingress. These problems not only posed risks to the structural integrity of the building but also threatened internal assets.
Weatherproofing Advisors were tasked with identifying a practical and durable approach to address the current failures whilst extending the roof’s lifespan.
Weatherproofing Advisors recommended removing the existing kerb edge detail along the southern elevation of the roof as part of the roof replacement works.
This modification is intended to address the inefficiency of the current chute-style outlets, which has proven ineffective at discharging water from the roof. By eliminating the kerb, water will be able to discharge more freely and efficiently from the roof surface, significantly reducing the risk of standing water and associated issues.
This approach also negates the need for costly tapered insulation to create falls, offering a more straightforward and economical drainage solution.
