Cowbridge Nursery Roofing Refurbishment

When the Little Angels Nursery in Cowbridge experienced leaks, the property managers put out a contract for the roof repairs. Local roofing contractors Roofing Matters the recommended Roofers Cowbridge won the contract and immediately began to examine the nursery roofing system. What they found is that a series of cracks in the existing bitumen roofing system were too severe and widespread to be properly repaired. Instead, they decided that a complete refurbishment was in order, and they laid out detailed plans for how they were to go about that. Once the plans were approved by the clients, the contractors got to work.

They first installed a new joint on the roof. This would allow them to connect the new roofing system to the joint while securing it over the old roofing system base. Using a technique that joins sections of the roofs by compression, they installed a hot join to the already established bitumen roof.

The roof that was being built over was a layered felt roof and it had a chipping finish. This would keep the rays of the sun from damaging the felt, and this is a setup that is quite common for roofs of domestic structures, but is also sometimes used in commercial buildings. The nursery had likely started out as a domestic construct that was later turned into a commercial one.

Once the old roof has been discarded, a new timber decking was used over it. Choosing the right decking to place over an old roofing system is complex work, and it often isn’t definitely chosen until after the initial roofing system is removed and the under-structure can be properly examined. In this case, the contractors decided that timber roofing would give the clients the look they wanted and allow for proper waterproofing on a flat roof system.

Once the new roof was completed, it was covered in a waterproofing finish. The roof had been put in in sections of three metres wide. This allowed for quick and efficient installation and saved the clients time and money. OSB grade 3 plywood was used for the roof decking. It is used in many roofs and is well regarded for its quality. It also bonded well with the waterproofing method that Roofing Matters was using. The thick membrane that was used to help protect the roof from water ingress and the way the lamination was manufactured meant that the sections of the roof could not exceed much more than three metres in width. Even the roofing sections that are marketed as very wide sheets are really just sections of sheets that are three metres wide, and they are joined together into larger sheets. Roofing Matters wanted to avoid using these sheets, even though they would have been cheaper and faster to lay down, because they were not joined by an accredited roofer, but instead put together in a factory.
