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. The membrane should be repaired and retested before any further layers are added, according to NHBC Chapter 7.1.9 (Green Roofs & Propriety Roofs).

Premier Guarantee Structural Warranties go 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.

Common Symptoms Of A Flat Roof Leak

  • 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. Because water stains can occur on ceilings due to other issues, such as plumbing leaks, a professional roof inspection may be necessary.
  • A flat roof leak may be indicated by signs such as peeling wallpaper and paint. Leakage can be signalled by peeling wallpaper or paint which is caused when water seeps from the ceiling into the attic. High humidity and condensation can also lead to this, you should have a professional roof inspector inspect your roof to confirm that there aren’t any leaks.
  • A flat roof leak could be the cause of a musty or mouldy odour. 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 be a health hazard and should be corrected 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.

Roof Leak Detection FAQs

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.
