Why Is It Important To Identify Flat Roof Leaks Quickly
Your flat roof is an important aspect of your building, protecting the structure as well as the contents from the weather. 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 roof leak detection specialists can inspect your roof to identify the source of the leak quickly and prevent costly repairs and replacements.
Poor installation, poor maintenance and exposure to severe weather can all make flat roofs susceptible to leaks. Flat roof leaks can result from a number of factors including cracked flashing, blocked gutters and punctures caused by falling 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. 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.
Our team provides both residential and commercial roof cleaning and roof maintenance services in St Johns and throughout the Greater London (Lewisham) area, including Greenwich, New Cross, Blackheath, Ladywell, Lewisham.

Integrity Testing For New Flat, Green And Blue Roofs
Any flat, green or blue roofs should adhere to NHBC Chapter 7.1. Flat Roofs. Terraces. and Balconies in addition to British Standard 6229: 2018, (Flat Roofs with Continuously Supported Flexible Weatherproof 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. 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. 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 includes an inspection and assessment of all roof penetrations, terminations, mounts for equipment, roof membrane conditions, parapet wall coping and perimeter flashing.

- Reduce Repair Costs - The longer that a roof leak remains unnoticed the greater the damage it will cause. This will require more expensive and complicated repairs than if it was discovered sooner. Rapidly identifying leaks can minimise damage and reduce repair costs.
- Saving On Energy Costs - 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 reduce your energy consumption by finding roof leaks early.

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 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.
- A flat roof leak may be indicated by signs such as peeling wallpaper and paint. If water seeps through the ceiling, it can cause wallpaper or paint to peel off of the wall. 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.
- A mouldy or musty odour may also be a sign of a leak in your 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 could be a health hazard and should be corrected immediately.
- Condensation from the inside is another indication of a flat roofing leak. Condensation on the roof surface can occur when the temperature inside is higher than outside. This signals a leak. This can also be caused by either inadequate insulation or inadequate 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
