Flat Roof Leaks: The Importance Of Identifying Then Quickly
Your flat roof is an important part of your building as it protects the structure and your contents from the weather. However, flat roofs have a higher risk of leaking than sloped roofing, and if not dealt with promptly, even a minor leak can become a major problem very quickly. With a leak, your flat roof may allow water to enter your home through multiple points, this can seriously damage your property and the contents. Our roof leak detection specialists can inspect your roof to identify the source of the leak quickly and prevent costly repairs and replacements.
Flat roofs can leak due to many factors including, poor installation, inadequate maintenance, or exposure to severe weather. Flat roof leaks can result from a number of factors including cracked flashing, blocked gutters and punctures caused by falling objects.
It is important that you remember that not all roof problems are obvious, roof leak experts have the experience and the tools to be able to detect roof leaks. A regular roofing maintenance plan will help to keep your roof in good repair over the long term, and regular roof inspections can also be helpful to detect minor leaks before they become serious problems.

According to section 7.11.25.2 of the “Roof Coverings – Green Roofing” section 7.11, the waterproof membrane must be tested for integrity before any other components are added to it.

This could lead to expensive repairs or even the danger of your building collapsing. Early leak detection will help preserve your building’s structural integrity, and help avoid larger damage.
- Preventing The Formation Of Mold And Mildew - Roof leaks can result in the growth of mould and mildew, which can have detrimental effects on the health of your building’s occupants. You can keep your building safe, healthy and free from mould and mildew by finding leaks in the roof early.
- Reduce Repair Costs - The longer a leak is not fixed the more damage it creates. This will mean that repairs are more complicated and expensive than if the problem was identified earlier. By identifying leaks quickly, you can reduce damage and save money.
- Energy Cost Savings - A roof leak could also lead to higher energy bills, as the leak’s location can cause draughts, which can make it harder for your building to stay at a moderate temperature. You can cut down on your energy costs by finding roof leaks and fixing them quickly .
- Reducing Insurance Costs - If your building has a history of water damage then you may get charged higher premiums by your insurance company. It is possible to keep your insurance premiums down by identifying any leaks early and avoiding damages.

Common Symptoms Of A Flat Roof Leak
- Water stains on the ceiling are one of the most evident indicators of a flat roof leak. These stains can be in the form of water droplets or discoloured patches and could indicate a roof leak. 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. Condensation or high humidity can also cause this problem, therefore, it is crucial that a professional roof inspector assesses your roof for any leaks.
- Mouldy or musty odours could also indicate that you have a leaking roof. A leaky roof can promote the growth of mold or mildew and cause a musty odour. This can pose a serious health risk and must be addressed immediately.
- Condensation inside the roof is another sign of a flat roof leak. If the temperature inside the building is higher that the outside, condensation can form on the roof surface. This signals 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
Does insurance cover flat roofs?
Insurers in most cases will define flat roofs as being pitched at 10 degrees or less. Having a small part of your roof being flat usually is not a problem, but if over 25% of your roof is flat, you may find that most insurers may not be able to offer you any cover at all.
How long does flat roof sealant last?
Summary: roof coating systems last 10-20 years, but once they reach the end of their warranty, they can be recoated and a new warranty begins. The process can be repeated, making roof coating systems a renewable and sustainable roofing system.
Should a flat roof hold any water?
Whilst brief and occasional ponding is acceptable on a flat roof, regular or long-lasting ponding could be an indication that there is an issue with the roof that needs to be addressed.
Should I avoid buying a house with a flat roof?
Flat roofs are considered versatile and simple to maintain, but they can also be costly to repair. They are an energy-efficient alternative to sloped roofs but often come with issues such as a higher risk of leaking and water pooling. Flat roofs often have a shorter lifespan compared to sloped roofs
What is the major disadvantage of using a flat roof?
The biggest drawback of flat roofs is the drainage or lack thereof. Sure, flat roofs do have a slight slope that drains the water, but not nearly as efficiently as a pitched roof. The rainwater tends to remain on the roof and form a puddle, which can lead to possible leaks or material damage
