OurServices

We offer independent and unbiased non-destructive roof condition surveys, including electronic leak detection and integrity testing on new or existing flat roof and other structural waterproofing membranes for Industrial buildings.

Surveyroof can find the point of entry quickly and accurately using our cost effective electronic leak detection methods and thermal imaging surveys.

    • Industrial Roof Surveys

      Holiday Detector Test

      Often referred to as the “dry test”. This method of flat roof electronic leak detection is ideal for use on any flat or low pitched roof to identify breaches in exposed membrane systems allowing for a quicker testing schedule identifying imperfections such as pinholes and punctures. This test can only be performed in dry conditions.

      Method

      The detector delivers, via a phosphor-bronze brush, a stabilised D.C. output voltage across the non conductive waterproofing membrane under test. Detection of breaches is by an audible tone and a visual spark from the search electrode (brush).

       

      Earth Leakage Leak Detection

      Often referred to as the “wet test”. This method of flat roof electronic leak detection is ideal for use on any flat or low-pitched roof to identify imperfections in exposed membrane or ballasted systems. This test is performed in wet conditions (rainfall) or with a hosed down wetted test area.

      Method

      A pulse generator emits pulses with a voltage of 40V which are conducted onto the roof structure via a wire ring circuit. Since all roof membranes are more or less non-conducting, the electrical pulse chooses a path across the moisture to where the leak is located and then flows over the damp roof in all directions to reach the ring circuit.

      We can now determine the currents direction of flow and trace it back to its source. This source is exactly the spot where moisture is penetrating the roof membrane.

    • Thermal Imaging Leak Detection

      Thermography is a non-destructive type of testing and is an invaluable resource for predictive maintenance to assess flat roofs for saturated insulation and entrapped moisture. This allows industrial building owners to make an informed decision to action any defects identified to extend the life span of your roof.

      All our Thermographers use the Flir Systems P640 range of equipment, the highest resolution camera available to ensure we pick up details lesser cameras may miss.

    • Roof Maintenance Programmes

      Extend your roof life – Having a roof maintenance program is the fundamental key to achieving maximum roof life with minimal problems.

      Keep costs down with a comprehensive roof maintenance program solution from Surveyroof Ltd.

      A photographic report will be provided on completion so that the client can action any issues identified to extend the life span of your roof.

       

      Your roof protects you, your workers, and your capital expenditures and is subjected to constant wear and deterioration. Nothing lasts forever, and even your roof is subjected to constant wear and deterioration and its life span, in comparison to the life span of the structure holding it up, is short.

      It is then probably safe to say that a comprehensive roof maintenance program is an essential part of extending the useful life of your roof. Our roof maintenance programs are saving owners and property managers thousands of pounds in unplanned roof expenditures.

      Our roof maintenance program technicians are trained to ensure you are provided with the highest quality of workmanship. Our roof maintenance programs can be tailored to suit the client and as such can consist of many different services to include:

      Quarterly / Bi-Annual / Annual site visits
      Electronic Leak Detection / Diagnostic Testing
      Removal of all rubbish, debris and leaves from roof areas and gutters
      Inspect all rainwater outlets, replace leaf guards
