Following on from the fire compliance works recently completed at The Norton Knatchbull School, in Kent, Ashley Consultants were subsequently commissioned to help address the long term, persistent roof leaks that the school building had been experiencing.

At the outset Ashley Consultants conducted a detailed survey of the existing pitched roof which featured man-made slate coverings with a central glazed lantern. These were shown to have both failed, resulting in costly leaks which were disrupting teaching, damaging resources and causing excessive energy bills.

We then prepared a detailed technical specification and successfully obtained CIF funding to complete the required works.
The specified solution involved installing a new synthetic slate roof covering with a 40-year BBA certified service life, along with associated building remedial works.

In addition to the new synthetic slate roof covering, new brackets have been provided for PV panels to ensure lifetime weathering, single point of responsibility, and secure fixing of existing PV panels on completion.

Elsewhere the central lantern has been replaced with composite metal sheets to provide a superior u-value and lower ongoing heating costs for the school. Natural light transmission has been retained via glazed openers, also facilitating natural ventilation. In addition, a number of access and fire safety improvements have been made, with suspended internal ceilings also being replaced concurrently with the roofing works.

To minimise any disruption to the school a meticulous and detailed project delivery programme was formulated, whereby heavy and disruptive construction tasks were prioritised over the summer holidays. Concluding tasks were then completed on a sequential phased basis, which enabled the building to remain in use without disturbance to teaching.

The works works were completed over the summer holidays and during term time, and consisted of:

In summary, this has been an excellent project, resulting in a leak-free, energy-efficient roof and a far better teaching environment for all concerned.

Throughout this comprehensive project, full project management has been provided by Ashley Consultants, liaising between all parties to ensure site safety and efficiency of programme. This ensure that the project was delivered on time and within budget for the client.
