Why Is It Important To Identify Flat Roof Leaks Quickly
Your flat roof is an important part of your building as it protects the structure and your contents from the weather. 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. 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 inspectors can inspect your roof and determine the source of the leak quickly, which will help you to avoid 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 could be caused due to cracked flashing, blocked gutters or 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. 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
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 a roofing membrane is overlaid it should be visually examined and electronically tested for 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 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.
A roof survey will be done and all roof penetrations will be inspected. This will include an evaluation and assessment for any roof penetrations, , terminations, mounts for equipment, roof membrane conditions, parapet wall coping and perimeter flashing.

- Repair Costs Can Be Reduced - The longer that a roof leak remains unnoticed the greater the damage it will cause. This will lead to more complicated and costly repairs than if the leak was found earlier. By identifying leaks quickly, you can reduce damage and save money.
- Saving On Energy Costs - A roof leak can cause draughts and make it harder to keep your building at a comfortable temperature, which can increase your energy costs. You can cut down on your energy costs by finding roof leaks and fixing them quickly .

Flat Roof Leaks: The Signs To Look For
- 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. Water stains on the ceiling may also be caused by plumbing leaks, therefore a professional roof inspection will help to pinpoint the source.
- 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. This can also be caused by high humidity or condensation, so it is important to have a professional inspect the roof to ensure there are no leaks.
- A flat roof leak could be the cause of a musty or mouldy odour. Water can cause mould growth and mildew to grow inside the structure, which can lead to your property having a musty odour. This could be a health hazard and should be corrected 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 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 FAQs
Why put gravel on a flat roof?
Gravel and pea shingle have two primary purposes on a flat roof; they provide a 'loading coat' and they afford UV protection. As ballast, the gravel will help anchor the material underneath and lower the risk of it being blown off in high winds.
Does walking on a flat roof damage it?
Flat Roofs A flat roof is less precarious than a pitched one, but you still run the risk of damaging the felt and potentially going through the membrane. You're less likely to cause damage on a warm day, and it's generally advisable to lay boards across it to walk on.
What do roofers use on flat roofs?
The most common ones include EPDM rubber, single-ply (TPO, PVC), modified bitumen, built-up roofs (BUR), and spray polyurethane foam. Many homeowners choose either EPDM or TPO. EPDM roofs are affordable and can reach a lifespan of 30+ years.
What is the most common defect in flat roof?
Leaks. 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.
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.
