  • How To Prevent Water Infiltration

    Many preventive measures can help you avoid water ingress. First of all, roof maintenance is essential, and even more so if you have a flat roof. In fact, you must be on the lookout for any accumulation of water on your roof that could cause a leak, especially after a heavy rainfall. You must ensure that rainwater drainage is optimal on your roof and that it does not stagnate. If water accumulates frequently and remains there for a long time, it may be a problem with the roof slope, which you will have to adjust to promote better drainage.

    Next, check the condition of your gutters and clean them twice a year, in the fall and spring. Gutters that are clogged or obstructed by debris, such as leaves or branches, will not allow water to drain properly, which could cause infiltration. If you wish to limit the risk of debris build-up, you can install gutter guards, which will prevent leaves and other debris from getting inside the eavestroughs.

    Finally, regularly inspect the membrane of your flat roof to prevent water infiltration. Regular maintenance will not only prevent leaks and keep your roof healthy for years to come, it will also prevent you from having to replace your roof due to careless maintenance!

    How To Find A Roof Leak: No Attic Flat & Infrared

    While you may see a wet spot on your ceiling or water dripping from the ceiling, finding the exact location of the leak can be quite a tricky task. In fact, a large part of fixing a leak entails correctly identifying the source of the leak.

    What makes it to find roof leaks is that water works in a very different way from other substances. In our experience, most leaks occur way higher than the area you observe them from. For example, a leak can occur at the top of the roof then water flows along the roofing and only appears on your ceiling at the point where the roofing beams meet.

    The strategy youâll need to identify the source of the roof leak will depend on the actual source of the leak. While some leaks can be identified from the house, others will need going into the attic. Still, others may require you to climb on the roof or even pour water on it to check how it behaves.

    Checking Ice Dam Leaks

    Flat Roof Leaks

    Ice dams form when melting snow from the upper sections of the roof is cooled to ice at the edge of the roof. As more water flows from the upper sections of the roof, the ice dam grows larger with time. Besides exerting unnecessary weight on the roof, the ice dam holds water on the shingles for long periods of time. The water can easily find its way into the roof leading to leaks and eventual rots.

    While you can climb into the attic to check the leak from an ice dam, there isnât anything you can do from that angle. The best way is to remove the ice and snow from the roof then check for the area affected by the ice dam and what led to the leak.

    In some cases, you might not even find the leak after the ice dam is removed. This is because the leak could be due to the pressure exerted on the roof and not necessarily a broken part of the roof. The weight of the ice may warp some areas or undo a seal letting water into the roof. When the ice is removed, the part may recover its original shape and level of sealing.

    In our view, the best way is to remove ice dams as soon as possible since they may lead to the formation of ice on the whole roof. This puts a lot of pressure on the roof with the likelihood that the whole roof could come down.

    Can I Claim On House Insurance For A Leaking Flat Roof

Often, if the leak was not caused by an unexpected event such as a heavy storm or a falling tree, this damage would fall under general wear and tear and youd have to pay for any repairs yourself. Your insurer will look for obvious signs of external damage that may have caused the roof leak, such as damage to your roofing membrane. If no such damage exists, you are likely out of luck.

    Applying The Roof Sealant Paint Or Coating

    Flat Roof Leaks

    Watch out: Inspect the roof surface very carefully everywhere, on hands and knees, to be double sure you have not left any un-sound roof coating or loose areas that need more scraping and cleaning.

    And do not start applying roof sealant coatings if you are not confident that your roof will have adequate drying time before any incoming rainy weather.

    Watch out: sweep again before you start pouring out roof coating. You may be surprised how much more dirt and debris you’ll collect.

    Watch out: plan your work sequence, starting at the area of the roof most distant from your ladder or exit point.

    Above you can see we’ve poured out a dollop of our roof coating material and have begun to spread the roof sealant.

    Take extra care to seal the juncture of roof surface with any parapets on a concrete roof. I’m using a disposable long-handled brush that makes the application of roof sealant faster and more comfortable. If you try this with a little paint brush you’ll be sorry.

    I’m pulling a thick roll of roof sealant in front of the brush edge .

    If I don’t see that I’ve got that leading roll of sealant on the front edge of my brush I know I need to pick up more from the poured out coating. As the sealant is applied I stop and brush sealant into the joint of roof top and parapet wall, and I inspect for any bubbles, cracks, or pits that are forming voids in the coating.

    If necessary I brush back and forth a few strokes to be sure these are completely closed and sealed.

    Don’t do that.
