A flat roof leak could allow water into your home from multiple places, this can then cause severe damage to your property and the contents. within. Our roof inspectors can inspect your roof and determine the source of the leak quickly, which will help you to avoid costly repairs and 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).
It is important to visually inspect and electronically test the waterproofing integrity of roofing membranes before they are overlaid. 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 take it one 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. Testing should be performed by an independent party not connected to the roofing contract.
All roof penetrations will be inspected and the roof surveyed. This includes an inspection and assessment of all roof penetrations, terminations, mounts for equipment, roof membrane conditions, parapet wall coping and perimeter flashing.

- Avoiding Mold And Mildew - Roof leaks can lead to the growth of mildew and mould, which can have a negative impact on the health and well-being of the building’s occupants. You can keep your building safe, healthy and free from mould and mildew by finding leaks in the roof early.
- Repair Costs Can Be Reduced - The longer a roof leak goes unnoticed, the more damage it causes. This will result in more costly and complex repairs than if the leak was detected earlier. Rapidly identifying leaks can minimise damage and reduce repair costs.
- Save On Energy Costs - Roof leaks can lead to higher energy costs, because the leaks location may result draughts making it more difficult to maintain a comfortable temperature. If roof leaks can be detected early it could reduce your energy costs.

Flat Roof Leaks: Common Symptoms
- A flat roof leak can be easily detected by water stains on the ceiling. These stains could be either discoloured patches or water droplets and can indicate that your roof is leaking. Because water stains can occur on ceilings due to other issues, such as plumbing leaks, a professional roof inspection may be necessary.
- Another sign that you have a flat roof leak, is peeling wallpaper or paint. The wallpaper or paint may start peeling off the walls when water seeps into the attic and through the ceiling. Condensation or high humidity can also cause this problem, therefore, it is crucial that a professional roof inspector assesses your roof for any leaks.
- Moldy or musty odour could also be an indication of a leaky flat roof. Water can cause mould growth and mildew to grow inside the structure, which can lead to your property having a musty odour. This can pose a serious health risk and must be addressed immediately.
- Condensation from the inside is another indication of a flat roofing leak. When the outside temperature is higher than inside, condensation can build up on the roof’s surface. This indicates a leak. This can also be caused by either inadequate insulation or inadequate ventilation.
Remember that these symptoms can also be caused by other problems, so a professional roof inspection should be carried out to find the exact source of the problem.

Roof Leak Detection FAQs
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.
