How Important Is It To Identify Flat Roof Leaks Quickly
A flat roof is an important part of your building as it protects the structure and contents. Flat roofs can be more vulnerable to leaks that sloped roofs, and if they aren’t addressed quickly, a small leak can very quickly grow into a serious problem. Flat roof leaks can lead to multiple water entry points in the area below, which could cause severe damage to your property and the contents. Our roof inspection experts can help identify the source of leakage quickly, preventing any serious damage to your property and its contents, avoiding costly repairs and replacements.
Flat roofs are susceptible to leaks because of a number of factors, including inadequate installation, poor maintenance, and being exposed to severe weather. Flat roof leaks are caused by many factors such as cracked flashings, blocked gutters and punctures from fallen objects.
It’s important to remember not all roof leaks can be easily detected without the help of experts with the right tools and experience. Regular professional roof inspections are a good way to ensure that your roof is in good shape and help to detect any potential issues before they have become a major issue.

Integrity Testing For New Flat, Green And Blue Roofs
Any new flat, green or blue roofs must comply with NHBC chapter 7.1 of Flat Roofs. Terraces. And Balconies and British Standard 6229. 2018 (Flat Roofs with Continuously Supported Flexible Waterproof Coverings. Code of Practice).
Before any roofing membrane is overlaid, it must be visually examined and electronically tested to ensure waterproofing integrity. Any potential flaws in the membrane must be corrected and then the membrane should be retested before being overlaid, in accordance with NHBC Chapter 7.1.9 (Green Roofs & Propriety Roofs).
Premier Guarantee Structural Warranties take it one step further. According to section 7.11.25.2 in the “Roof Coverings –Green Roofing”, section 7.11, waterproof membrane integrity must be verified before any other components can be applied. The testing should be done by a third party, who is not related to the roofing contract.
An inspection of all roof penetrations will be performed and the roof will be surveyed. This will include an assessment and examination of any roof penetrations, terminations, mounts for equipment, roof membrane conditions, parapet wall coping and perimeter flashing.

Flat Roof Leaks: The Signs To Look For
- A flat roof leak can be easily detected by water stains on the ceiling. These stains may appear as discoloured patches or water droplets and can indicate a leaking roof. To find the source of the problem, a professional roof inspector is required, as water spots on the ceiling could also be caused other problems such as plumbing leaks.
- If a flat roofing is leaking, it may be indicated by peeling wallpaper or paint. When water seeps down through the ceiling and into your attic, wallpaper or paint may peel off from walls. This could indicate a leak. High humidity and condensation could also be the cause of this, to ensure that there are no leaks, it is essential to have a professional roof inspector examine your roof for 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 could present a significant health risk, and it must be fixed immediately.
- Condensation inside the roof is another sign of a flat roof 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 poor insulation or inadequate ventilation.
It is important to remember that symptoms like these can also be caused by other problems, therefore a professional roof inspection is necessary to pinpoint the root cause.

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.
