Building leaks can equally occur in new build as well as existing properties and Thornton Consulting were recently appointed to undertake our Building Leak Investigation and Roof Condition Survey services to a restaurant roof in Oxford.
The building was approximately 3 years old and had been experiencing an internal leak for more than a year.
The building leak investigations process was undertaken to locate the source and cause of a leak and combined a number of test techniques to positively identify the source of the water ingress. Tests included:
Roof moisture profile
Electronic test of the waterproofing membrane
Simulated rainfall test, incorporating a trace dye
Internal monitoring of the leak site for change in moisture and water ingress
The leak source was identified as a breach in the single ply waterproofing which was later repaired by our client’s roofing contractor and re-tested to confirm its integrity.
Our client also required peace of mind that there were no further issues with the roof. We, therefore, undertook a Roof Condition Survey to the whole roof to confirm the integrity of the roof waterproofing and establish any potential items of concern.
Roof condition surveys assess the current performance and condition of a roof and can provide an indication of the remaining lifespan. A number of different test techniques can be employed depending on the specific requirement of our clients, but the service can include:
Electronic leak detection of the waterproofing membrane
Roof moisture profile
Visual inspection and assessment of condition and projected lifespan
Technical audit of the roof
Core samples
Comprehensive report with images and drawings
A roof condition survey is equally important to property owners, facilities managers or anyone else who has an aged flat roof looking to prepare a budget for replacement or repair. The survey will not only provide information on the roof covering but can also include other items which are considered to be potential points of water ingress into the structure.
Thornton Consulting can assist in prolonging the serviceable life of a roof, where necessary, by incorporating this into a roof maintenance programme and ensuring the correct remedial works are undertaken to prevent internal leaks.
Thornton Consulting undertake Roof Condition Surveys to most types of waterproofing, including:
Mastic asphalt
Built-up felt
Single ply
Hot melt
