Commercial Flat Roof Refurbishment For Gentoo Sunderland
The Work Flat Roof 800m2
We carried out commercial flat roofing work for Gentoo Stores, located in the Sunderland area. The existing flat roof construction was a metal deck built up with a half-inch fibreboard and two layers of felt. The roof had reached the end of its service life, and the risk of leaks had to be addressed to avoid any water ingress.
To minimise the risk to health and safety, avoid disruption to customers and ensure that the building could operate on a business-as-usual basis, a Protan single-ply system was specified by Moy Materials after site surveying of the existing substrate. A Protan single-ply system was preferred for this commercial flat roof project to aid ease of detailing and cover and complete/waterproof large areas in a day’s work.
The customer was also keen to ensure that the chosen system could be installed within a short programme and stipulated a 20-year guaranteed service life in line with their building maintenance programme.
Following a site audit and condition survey carried out by MOY Material’ Area Technical Manager, DVC Roofing, was appointed to carry out the project, and a full specification was compiled.
A Protan Single Ply System was specified for the roof, ensuring that the new waterproofing membrane could be applied quickly and efficiently as the roof area was open to the elements once stripped.
The DVC team began by stripping down the roof to the existing structural metal deck and applying a heavy gauge Vapour Control Layer. The team then fitted insulation, Protan Single Ply, and welded overlapped joints. This system and method of works allowed us to complete the sections we had stripped.
An employee from DVC Roofing said: “We were working in a busy environment with offices located below us. We had to factor in everything the weather had to throw at us, including high winds, heavy rain, and snow.
The ease of use of the system and the technical support offered by MOY Material’s field technician team ensured we were able to manage all the box gutter detailing completing the job to a high standard and within the customer’s deadline.”
