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 are more likely to leak than sloped roofs and even a minor leak can very quickly escalate into a major problem if it’s not fixed promptly. A leak in your flat roof can lead to multiple water entry points, which can cause serious damage to your property and the contents. Our leak detection experts will inspect the roof and find the source of any leaks quickly, helping you to avoid expensive repairs or 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 is important to remember that not every roof leak is obvious, without the specialist tools and experience of an roof leak detection specialist, some leaks may be difficult to identify. 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.

It doesn’t matter what the weather is like for a leak detection survey. After your flat-roof survey is completed, you will receive a complete Health and Safety Plan and Risk assessments, as well as Method Statements. These together make up an extensive O&M Manual.

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 any roofing membrane is overlaid, it must be visually examined and electronically tested to ensure waterproofing integrity. 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. 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. The testing should be done by a third party, who is not related to the roofing contract.
A roof survey will be done and all roof penetrations will be inspected. This will include an inspection of any roof penetrations, terminations, mounts for equipment, roof membrane conditions, parapet wall coping and perimeter flashing.

It Is Vital To Detect A Leak Quickly For Property Protection.
- Prevention Of Structural Damage - If not taken care of promptly water leaks can harm your building’s structural integrity. These water leaks can lead to costly repairs and even the possibility of your building collapsing. Early detection of a leak can help you preserve your building’s structural integrity and prevent further damage.
- Avoiding 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. Early detection of a roof leak can help to keep your building safe and healthy by stopping the spread of mildew and mould.
- Reducing Repair Costs - The longer that a roof leak remains unnoticed the greater the damage it will cause. 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. If roof leaks can be detected early it could reduce your energy costs.
- Lowering Insurance Costs - Insurance companies may increase your premiums if there is a history of water damage. Avoiding water damage by finding leaks quickly can help you keep your insurance premiums low.

Common Symptoms Of A Flat Roof Leak
- A flat roof leak can be easily detected by water stains on the ceiling. These stains can appear in the form of discoloured patches, or even water droplets, and could indicate that there is a roof leak. Water stains on the ceiling may also be caused by plumbing leaks, therefore a professional roof inspection will help to pinpoint the source.
- A flat roof leak may be indicated by signs such as peeling wallpaper and 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.
- A mouldy or musty odour may also be a sign of a leak in your flat roof. The growth of mould and mildew can occur when water enters the structure, leaving you with a musty odour. This can pose a serious health risk and must be addressed immediately.
- Another sign of a leaky roof is condensation on the roof’s inside. If the temperature inside the building is higher that the outside, condensation can form on the roof surface. This signals a leak. It could 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.

Flat 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
