The asset of differential pressure testing for roof membrane integrity

Differential pressure testing is a critical procedure in evaluating the integrity of roof membranes. It is used when traditional electronic leak detection of waterproofing membranes is not possible, often as a result of a particular roof construction. This could be due to the membrane being conductive, EPDM for example, or where the substrate is non-conductive, such as timber.

The differential pressure testing process involves applying negative pressure through a Perspex chamber placed on the surface of the waterproofing and monitoring the laps within the chamber for integrity. A surfactant applied to the laps will indicate where a water path is present which can then be marked on the roof surface and repaired by the contractor.

Here are some reasons why differential pressure testing is a valuable asset for waterproofing roof membranes:

1.   Accurate Detection of Leaks: Roof leaks can be challenging to identify because water can penetrate the membrane in one area and travel a considerable distance before showing up inside the building. Differential pressure testing can accurately detect even the smallest of leaks by creating negative air pressure on the outside of the waterproofing membrane and positve air pressure beneath. Any holes, tears, or punctures in the membrane will cause the air to escape, which can then be observed through a perspex chamber.

2.  Cost-Effective: Repairing a leaking roof can be expensive, especially if the problem is not identified early enough. Differential pressure testing can help identify potential problems before they become major issues. This process can save building owners, contractors and roofers considerable expense in repair costs by identifying leaks early and allowing for prompt repair.

3.  Manufacturer Warranties: Many manufaturers require roof membranes to be tested for intergrity by an independent party . Differential pressure testing is an excellent way to meet these requirements and ensure that the roof system is performing as intended.

4.  Verification of Installation Quality: Roof membranes are often installed by a variety of contractors, and their workmanship can vary greatly. Differential pressure testing can help verify that the installation was done correctly, and the roof system is functioning as intended.

5.  Peace of Mind: Roof leaks can be stressful and disruptive to building occupants. Differential pressure testing provides peace of mind by ensuring that the roof system is working correctly and there are no hidden leaks that could cause problems in the future.

Why an annual roof inspection is invaluable

 

An annual roof inspection is a preventative measure that can provide a range of advantages to the property sector. Thornton Consulting provide a professional and meticulous planned roof inspection and maintenance service in counties throughout the UK and Ireland. Here are some of the key benefits:

1.  Early detection of problems: Inspecting the roof area annually or biannually can help to identify any issues with your roof before they become major problems. This could include identifying breaches in the roofing membrane, cracks or other types of damage. Establishing any weak spots promptly can save property owners money in the long run by preventing the need for costly repairs in the future or even a full roof replacement.

2.  Extending the life of your roof: Regular inspections and maintenance enables small issues to be identified and addressed, preventing more serious consequences developing that could potentially lead to structural damage and deterioration of the building’s contents.

3.  Maintaining your warranty: Many roofing warranties require regular roof maintenance and inspections in order to remain valid. By scheduling an annual inspection, you can help to ensure that your roof remains sound and in compliance with your warranty terms.

4.  Improved energy efficiency: A damaged or poorly maintained roof can contribute to energy loss, with an increase in your energy bills. Annual inspections and maintenance can help to ensure that the roof integrity is secure and watertight and isn't contributing to an energy deficiency.

5.  Peace of mind: Knowing that the roof is in good condition provides reassurance for property owners. Scheduling a roof inspection annually with Thornton Consulting can help to identify any areas of concern so that these can be addressed before they develop into major problems. This can help you to feel confident that your property is protected from the elements and is safe and secure from water ingress.

Overall, an annual roof inspection and maintenance carried out by Thornton Consulting’s experienced team of Field Testers and Consultants, is a smart investment. By identifying and addressing minor issues early on, this can extend the life of your roof, maintain your warranty, and save money on repairs and energy bills.   Call us today on 01342 410508 to find out more, or, if preferred use the Contact Us Form
