Your 3rd Party Flat Roof Membrane Integrity Testing Specialists
For all your third-party Flat Roof Membrane integrity testing needs. We adhere to the stringent requirements of LABC, Premier Guarantee, and NHBC, ensuring your roof complies with British Standards 6229: 2018 and NHBC Chapter 7.1, regardless of whether it’s a new build or an existing structure.
NHBC Chapter 7.1.9 mandates visual and electronic testing of roofing membranes to confirm waterproof integrity before additional layers are applied. Our expert inspections catch and correct any faults, providing peace of mind and superior waterproofing.
Premier Guarantee section 7.11.15.2 highlights the necessity of independent third-party testing for green roofs, ensuring the integrity of the waterproof membrane before other components are installed.
We perform comprehensive roof surveys that review roof penetrations, terminations, equipment mounts, membrane conditions, perimeter flashing, and parapet wall coping. Our detailed inspections ensure all potential issues affecting watertightness are addressed.
While vacuum testing is effective for assessing off-site manufactured membrane seams, it is not recommended for verifying flat roof membrane integrity.
We understand each project is unique. Our extensive experience allows us to tailor our services to your specific needs, including providing Health and Safety Plans, Risk Assessments, and Method Statements, culminating in a detailed O&M Manual upon project completion.
