Roof Refurbishment and Maintenance
3 Weeks
The Estates Management team at St Peter’s School contacted us to see if we could help to transform the appearance of their sports hall and improve the buildings u-values. The school wanted to know what options were available that would improve the aesthetics and integrity of the building. It was agreed that the most suitable option would be to overclad the existing roof and install new guttering.
The sports hall roof had been in place since the building was first built and had begun to show signs of degradation in recent years. To prevent further damage and risk to the internal elements of the building and the equipment below, St Peter’s estates team were proactive in seeking out a contractor with a wealth of experience who could carry these works out in the timeframe required.
With the school summer holidays around the corner, it was imperative that this project hit the ground running as soon as term finished. Equally as important was for the project to be completed on time and before the children started back at school for the new term.
Prior to works commencing at the St Peter’s Site, it was important that we identified a suitable route for deliveries and materials. The site of the school is large but has limited access to the lower school areas where works were to commence. We devised and agreed on a delivery plan that could be shared with all relevant parties including delivery companies. This gave a very clear indication as to how materials and plant would access the required locations. We hired ground mats for specific areas of the grounds to prevent damage to the grassed surfaces with a traffic management plan in place for when deliveries were expected.
We started by setting up a clear compound area fenced off with heras fencing. Within the compound area, we were able to store materials, a mobile welfare unit, and a skip. The scaffold consisted of TG20 compliant triple height handrail to the perimeters with ladder access towers to both the north and south elevations. An additional boarded lift was put in place to allow for gutter works to be completed below the cranked eaves and wall sheets.
Our operatives installed Ash and Lacy galvanised steel AG40 bars using AB40 brackets to fix the new roof and wall sheets to. We overlayed the existing roof with cladding roll insulation to bring the building up to current building regulations. We used Firth Steel 0.7mm N1000R profiled sheets fixed to the AG40 bars using self-drilling fasteners. All detail work to ridge, curved eaves, verge and corner details were installed, with the majority coming from our in-house fabrication team. Where translucent panels occur, these were stripped out and replaced with a new double skin site assembled GRP system matching the profile of the existing and the new overclad.
We installed a new trimline type plastisol coated steel gutter complete with new stop ends and outlets in merlin grey, as a contrast to the goosewing grey roof and walls. We also installed five new plastisol-coated steel swan-necked square rainwater down-pipes.
Midway through the project, the client requested additional roof works to be carried out on an adjacent roof. The works consisted of a 30mm recovery board with a single-ply membrane covering approximately 80m² along with approximately 44lm of laminated steel flashings, mechanically fixed to all perimeter and upstand details.
Following our roof installation on the sports hall, PV panels were installed by others. Both roof projects were completed well within the programmed timescale much to the joy of the client, and the sports hall now has a much more modern look and most importantly, will help maintain the building’s integrity for years to come.
