SIG successful in CIF funding bid for St. John’s School


Project: St John’s School
Surveyors: Thornton Firkin
Roofing contractors: Dufell Roofing
Membrane: SIGnature Torch-On System

SIG Design & Technology used their know how and professional expertise to secure the government’s Condition Improvement Funding (CIF) for roof repairs to a 1740m2 project at St John’s School, Bishop Auckland. The school had previously been successful in accessing a lottery grant to refurbish their internal sports facilities but a CIF bid in 2015/16 had been turned down.

Built some 50+ years ago, the school’s original roof system had come to the end of its useful working life and persistent water ingress was a significant problem.

The school had learned how SIG was successful in developing CIF applications and so D&T’s national specification manager for bituminous membranes, Ian Dryden was called in to undertake a full roof survey will would provide the major justification for the much sought-after 2016/17 funding.

Working alongside surveyors, Thornton Firkin, he also developed a detailed project specification. The surveying practice went on to submit the bid to CIF’s panel, which was successful and included sufficient funding to allow for an acoustically insulated ceiling to be installed above the swimming pool.

SIG designed the roof, which was complex in parts, to comprise a mix of complementary interfacing products comprising the SIGnature bituminous roofing system, Armourplan single-ply PVC membrane and Steadman’s composite panels.

SIG’s specific documentation was also submitted as tender information to four contractors to enable the school to secure best value. SIG accredited contractors, Dufell Roofing Contractors of Darlington County Durham were appointed.

Not long after completion, the Foundation Stage and Children’s Centre building at Layfield Primary School in Yarm started leaking. Water ran down internal walls and damp patches spread across ceilings.

“We had problems with water ingress. We had to replace carpets and lots of ceiling tiles,” says school business manager Sarah Powell.

Fortunately, the problem has now been solved with the help of SIG Design & Technology, which specified its SIGnature Torch on System to remediate the leaking roofs once and for all. By avoiding complete stripping of the failed roofs, this strategy provided significant cost savings.

The leaking roof area consisted of two pitched oval roofs with a flat roof below. SIG’s investigation identified the cause of the problem as the oval roofs, where inadequate detailing around the perimeter upstands and at the intersection with the lower roof had allowed water to ingress and find its way through to beneath the flat roof and down the walls into the school.

“It was a constant battle for the school,” says Ian Dryden, SIG National Specification Manager – Bituminous Membranes.

Both flat and pitched roofs needed to be remediated. It was clear that the 450sq m flat roof was damaged beyond repair and needed to be stripped right back to deck.

A new roof was then added using the SIGnature system, specified with the self-adhesive SA VCL Vapour Control Layer, tapered insulation, SIGnature 25 Underlay and SIGnature AA Capsheet.

However SIG managed to find an economical solution for the 250sq m pitched oval roofs, which enabled the contractor to leave the original single ply roof in situ beneath the overlay rather than stripping and disposing of […]
