Geoshield Blue Roof Surveys And Testing
Facilities managers and property owners whether your blue roof is a new construction or an existing building the people responsible for design, construction and maintenance will be fully aware of the criteria within British Standards 6229: 2018 (Flat Roofs with continuously supported flexible waterproof coverings, Code of Practice) and NHBC Chapter 7.1 of Flat Roofs, Terraces, and Balconies.
In NHBC Chapter 7.1.9 (Green Roofs & Propriety Roofs) it is recommended that before covering a roofing membrane it should be visually inspected and electronically tested for waterproofing integrity, faults rectified and retested before further layers are placed.
Premier Guarantee Structural Warranties go further, ‘Roof Coverings – Green Roofing section 7.11, under section 7.11.15.2 ‘Testing should be undertaken by a third-party that is independent of the roofing contract’.
