Before roofing membranes are overlaid, they should be visually checked and electronically tested for waterproofing.

Section 7.11.15.2, “Roof Coverings –Green Roofing” section 7.11 requires that the waterproof membrane be tested for integrity prior to any additional components being applied.

- Structural Damage Prevention - Water leaks can damage your building’s structural integrity if they aren’t addressed promptly. These water leaks can lead to costly repairs and even the possibility of your building collapsing. Early leak detection will help preserve your building’s structural integrity, and help avoid larger 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. By detecting roof leaks early, you can help keep your building safe by stopping the spread of mildew and mould.
- You Can Reduce Repair Costs - The longer a leak is not fixed the more damage it creates. This will result in more costly and complex repairs than if the leak was detected earlier. By identifying leaks quickly, you can reduce damage and save money.
- Save 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. If roof leaks can be detected early it could reduce your energy costs.
- Reduce Your 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
- Water stains on the ceiling is one of the best indicators that a flat roof leak is occurring. 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.
- A flat roof leak may be indicated by signs such as peeling wallpaper and 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. 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 can pose a serious health risk and must be addressed immediately.
- Condensation from the inside is another indication of a flat roofing leak. When the temperature inside of the building is warmer than the outside, condensation may build up on the roof. This can indicate a leak. This could also be due to inadequate insulation or poor 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
What is the best way to stop a flat roof from leaking?
Install flashing. Adding flashings to your flat roofing system will prevent the most common sources of roof leaks. Flashing seals the seams around chimneys, guttering, vents, and more to prevent water ingress.
Can you seal a leaking flat roof?
For bigger sealing jobs, there are many flat roof sealing products homeowners can apply themselves: Roofer's tape. For slightly larger repair jobs on seams or tears, homeowners can use 6-inch wide roofer's tape. You'll prime the surface with a bitumen liquid coating and then roll the tape over the adhesive.
Are flat roofs more prone to leaking?
Flat roofs (a/k/a "low sloped roofs") are more prone to leaks than steep-sloped roofs. This is perhaps the worst kept secret in real estate. A flat roof is not designed with a path for water to run off quickly, which allows moisture to collect on the surface.
Is a leaking flat roof covered by insurance?
Most home insurance providers will cover the cost of repairs if roof leaks are due to a sudden, unexpected event, like storm damage or a falling tree. But you won't be covered for roof leaks that are due to wear and tear.
Is standing water on a flat roof OK?
On a performing flat roof ponding water is not a problem as it will drain, or even evaporate, away. However when your flat roof has uneven areas due to sagging, an insufficient slope, or drainage issues, the ponding water doesn't dissipate.
