Our leak detection experts will inspect the roof and find the source of any leaks quickly, helping you to avoid expensive repairs or replacements.

Integrity Testing For New Flat, Green And Blue Roofs
All flat roofs that are new have to comply with NHBC Chapter 7.1, Flat Roofs, Terraces, and Balconies, as well as British Standard 6229, 2018 (Flat Roofs With Continuously Supported Flexible Waterproof Coverings, Code of Practice).
Before roofing membranes are overlaid, they should be visually checked and electronically tested for waterproofing. Any problems should be addressed and the membrane tested again before any further layers are applied, according to NHBC Chapter 7.1.9 (Green Roofs & Propriety Roofs).
Premier Guarantee Structural Warranties extend this a step further. The waterproof membrane must be checked for integrity before applying any other components, as per section 7.11.15.2 under “Roof Coverings –Green Roofing” section 7.111.11. The testing should be done by a third party, who is not related to the roofing contract.
All roof penetrations will be inspected and the roof surveyed. This will include an evaluation and assessment for any roof penetrations, , terminations, mounts for equipment, roof membrane conditions, parapet wall coping and perimeter flashing.

Flat Roof Leaks: The Signs To Look For
- Water stains on the ceiling is one of the best indicators that a flat roof leak is occurring. These stains could be either discoloured patches or water droplets and can indicate that your roof is leaking. Water stains on the ceiling may also be caused by plumbing leaks, therefore a professional roof inspection will help to pinpoint the source.
- If a flat roofing is leaking, it may be indicated by peeling wallpaper or paint. Leakage can be signalled by peeling wallpaper or paint which is caused when water seeps from the ceiling into the attic. High humidity and condensation can also lead to this, you should have a professional roof inspector inspect your roof to confirm that there aren’t any leaks.
- Moldy or musty odour could also be an indication of a leaky flat roof. If water is allowed to enter the structure, it can encourage the growth of mold and mildew, which can lead to a musty odour. This can pose a serious health risk and must be addressed immediately.
- Condensation in the roof is another sign that there is a roof leak. When the temperature inside of the building is warmer than the outside, condensation may build up on the roof. This can indicate a leak. This could also be due to inadequate insulation or poor ventilation.
Keep in mind that these symptoms could also be caused by other problems. To determine the exact cause, a professional roof inspection may be necessary.

Roof Leak Detection Frequently Asked Questions
What is the most common defect in flat roof?
Leaks are an all-too-common occurrence in buildings with flat roofs. This is mostly because flat roofs tend to lose their ability to effectively shed water if not properly maintained. Once moisture is unable to drain from the roof, it's just a matter of time before it finds its way into the building.
Why do insurance companies not like flat roofs?
Why are flat roofs hard to insure? A flat roof collects debris and is subject to pooling, leading to roof damage and water leaks. It may require more professional roofing repairs or ongoing maintenance. Plus, flat roofs are not designed to bear as much weight as sloped roofs
Are flat roofs cheaper to replace?
A hallmark of modern home design, flat roofs can also be less expensive to install than sloped or pitched roofs. Flat roof repairs cost £700, on average, with high repair costs of about £1,100 and low costs around £300.
What are the problems with flat roofs?
Flat roofs tend to have more pressure exerted on them since they are flat instead of slanted. Sometimes this pressure can build up, and if the pressure and stress become excessive, it can cause your roof to crack. If your roof does crack, you should call a professional immediately.
How do you seal a hole in a flat roof?
Cut Patch and Coat Cut a patch that is about 6 inches longer and wider than the first patch. Spread roofing cement, set the patch into the cement, and spread another layer of cement over the patch. Once it has dried coat the area with aluminum-fiber coating.
