How Important Is It To Identify Flat Roof Leaks Quickly
Your flat roof is vital as it protects the structure and the content of your building from the weather. However, flat roofs have a higher risk of leaking than sloped roofing, and if not dealt with promptly, even a minor leak can become a major problem very quickly. Flat roof leaks can lead to multiple water entry points in the area below, which could cause severe damage to 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 are susceptible to leaks because of a number of factors, including inadequate installation, poor maintenance, and being exposed to severe weather. 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. 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.

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 only by an outside party that is not involved in the roofing contract.

You Need To Be Able To Quickly Detect Leaks In Order For Your Property To Be Protected For A Variety Of Reasons.
- Structural Damage Prevention - Water leaks can damage your building’s structural integrity if they aren’t addressed promptly. This could lead to expensive repairs or even the danger of your building collapsing. Early leak detection can save your building’s structural integrity and help to avoid further damage.

- Reduce Insurance Costs - If your building has a history of water damage, your insurance company may charge you higher premiums. Your insurance premiums can be reduced by finding any leaks promptly and avoiding any damage.

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.
- Moldy or musty odour could also be an indication of a leaky flat roof. 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.
- Condensation from the inside is another indication of a flat roofing leak. When the outside temperature is higher than inside, condensation can build up on the roof’s surface. This indicates a leak. This can also be caused by either inadequate 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
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.
