East Riding of Yorkshire Council has specified the innovative new BBA certified flat roofing system Topseal Direct Lay as a replacement roof covering for three buildings at Driffield High School in Driffield, East Yorkshire.
The school, which has 1,800 students from the Driffield and Yorkshire Wolds area, had experienced leakage to flat roofs on the school’s equipment storeroom, boiler house and maintenance department, as well as the Sixth Form building. The three roofs ranged from 25m2 to 120m2 in size.
Topseal Direct Lay, a liquid-applied GRP overlay system, was specified after initial roof inspections from Topseal and the Topseal approved installer, as it is a robust solution that is quick and convenient to fit and can be installed without the inconvenience of removing the existing flat roof structure. This means that all three buildings could remain fully functional whilst the work was being carried out by the Topseal Approved installer, which is the perfect solution for a busy high school such as Driffield High School.
At the same time that Topseal Direct Lay was installed for the Sixth Form building, the Topseal installer also upgraded its thermal performance with a layer of insulation to improve the building’s energy efficiency.
The school will benefit from a 20 year material and workmanship guarantee from Topseal on all three roofs.
Allan Frizzell, Technical Manager at Topseal, said: “We developed Topseal Direct Lay to overcome the issues with some flat roof replacement systems, which include the inconvenience of having a building out of action whilst the work is carried out and the need to dispose of the existing roof. Topseal Direct Lay was the ideal choice on this project as the work had to be carried out on a short schedule and whilst the school remained a live teaching environment.”
He added; “Our new Topseal Direct Lay will provide a long term ultra-low maintenance solution for Driffield High School. We are experiencing strong demand from local authorities who are looking for a permanent, easy to install flat roof solution for both small and large buildings.”
Driffield High School was so impressed with its replacement flat roofs that it invited Topseal to present to East Riding of Yorkshire Council about the new replacement flat roofing system. Since then Topseal has received a number of further orders for Topseal Direct Lay from other schools and council buildings in the area.
Topseal Direct Lay is BBA approved and is suitable for both new and refurbished flat roofs.
A versatile system, Topseal can be fitted directly onto tissue-backed insulation for a warm roof construction. Its visual appeal makes it suitable for showpiece architectural projects, whilst its leading technical performance means that it can even be used as the waterproof layer on large commercial buildings.
The innovative roofing system can be applied directly to a range of materials including felt, asphalt, concrete and tissue-backed insulation and all components are cold-applied, which eliminates the risks associated with the use of heat or flames during installation.
As with all Topseal systems, Topseal Direct Lay is only installed by the company’s national network of trained and approved Installers. Topseal Direct Lay is offered with an optional guarantee protection certificate and insurance backed guarantee.
Suitable for both domestic and commercial work, Topseal Direct Lay ensures minimal disruption on site and reduces landfill as removal of the pre-existing roof is not necessary. No new decking boards are required, minimising the risk of water penetration into the building during installation.
Topseal Direct Lay is available is a wide range of colours and finishes, including any BS/RAL colour topcoats, plus an anti-slip finish. The roof surface is suitable for walking on after only 1-2 hours, whilst it’s tough, impact resistant surface is able to withstand one of the most common causes of leaks in bitumen and felt flat roof systems – impact damage from wind-blown slates.
Topseal Direct Lay is suitable for use on most flat roof projects, including large flat roofs on commercial and local authority projects down to smaller domestic roofing projects.
The company provides full specification assistance from its experienced and knowledgeable team. The Direct Lay system is the latest in a range of highly reputable BBA certified roofing systems from Topseal which are designed to last a lifetime.
