The school’s roof was very old and showing serious signs of ageing, with blocked internal outlets causing severe ponding water on the roof and splits in the covering causing several leaks. Several edge details had disintegrated and were showing exposed rotting timbers beneath the decks which were deteriorating due to exposure. All in all the roof was in an incredibly poor state.
It became obvious to all parties that the whole roof had to be stripped and replaced, including the deck. Given the extent and size of the project the roof refurbishment had to be finished before the new school year started in September. The client also wanted to include new PV panels as energy conservation and environmental considerations were important to the school.
The Headteacher authorised works to start before the end of term to ensure the September deadline was met, provided that the works were phased to allow pupils to be relocated and areas to be cordened off during breaktimes.
For the waterproofing, Icopal put forward a specification of the Total Torch System capped with the depolluting Noxite® Eco-Activ® mineral capsheet. Improved thermal efficiency was provided by increasing insulation thickness/ U-value performance.
The rooflights were replaced with modern, more thermally efficient units. This would increase the amount of natural light and reduce the dependancy on internal lighting. New barrel skylights and additional rooflights were added to maximise the use of natural light. Falls were improved and tapered insulation was installed to the valley gutter of the butterfly roofs to improve drainage.
The school plans to add photovoltaic panels at a later date. Icopal's IcoSun Fix Console and weathering collars will be used to provide mounting for the new PV panels without comprimising the wateproofing.
Both the Headteacher and Bury MBC were very happy with the project.
Following installation of the green technologies at Holcombe Brook members of the school's eco-council, represented by pupils of the school, gave a presentation outlining the initiatives, which has helped the school to achieve Eco-Schools' prestigious environmental Green Flag Award.
