Polyroof’s experience working with schools made them the perfect choice to update the Beckfoot Allerton Primary School and Nursery in Bradford, which has stood since 1894.
After having served the community for so long, inevitable issues began to appear with the building’s roof. The Polyroof system was the ideal solution.
After conducting a survey of the 250m2 roof, it was determined that the Nursery roof and Rockets Building roof needed refurbishment.
The Nursery roof consisted of built up felt, 18mm fibreboard and metal roof deck, whilst the Rockets Building was built of Asphalt/concrete with aged solar reflective paint. Despite their differing materials, the condition of the roofs remained consistent, with both reporting issues.
The survey ultimately determined that the roof would benefit from a new high-performance waterproofing system to provide long-term protection from further issues.
Both roofs would also benefit greatly from a thermal upgrade which would provide lower fuel bills and energy consumption while also reducing the risk of condensation.
A bespoke specification was prepared to refurbish the roof. Polyroof’s Protec System, a hybrid polymer liquid system, was chosen due to its extremely fast curing and installation times.
Due to its fully cold-applied application the works could be carried out during the Primary Schools term times, without having to wait for closure periods between terms.
Liquid Roofing Limited, a Polyroof Approved Contractor, was chosen to undertake the works.
The first task was to strip back and remove the original waterproofing of the nursery roof. Meanwhile, the Rockets building was repaired where possible.
Once initial preparation had been completed, all surfaces were cleaned down and removed of any debris.
Both roof surfaces would then act as a support layer for the new warm roof construction that would be installed.
The roofs required a timber hard edge to be fitted around the exposed perimeters.
Polyroof 130mm Tissue-Therm Insulation was used in conjunction with insulation adhesive and installed over the vapour control layer which was applied before the insulation.
Polyroof’s extra-tough GRP trims were then installed to create neat and robust edge detailing for exposed perimeters before the main Protec system application commenced.
All areas requiring priming before main system application were primed and allowed to cure. Any joints in the insulation boards were sealed using Taping matt and Protec Resin and allowed to cure.
Once this preparation had been completed, the main Polyroof Protec System in Chromite Grey was applied in a first coat and allowed to cure. Once the cure was completed the final coat was applied. Due its RapidCureTM technology, the Protec can be walked on and over-coated 30-60 minutes after applications, meaning large roof areas can be made fully waterproofed within a matter of hours.
The project was successfully completed in the client target time frame and budget.
The completed roof was inspected by the Polyroof Technical Services teams, reporting very high-quality workmanship by Liquid Roofing Ltd.
After the inspection was completed, the client received Polyroof’s trusted Accredited System Guarantee, assuring them that the roof will last for decades to come.
