    The water on a flat roof does not drain as easily as it would on a roof with a pitch, but this problem can be easily remedied. In order to insulate the roof and stop water damage and heat loss, a two-coat application of elastomeric coating is typically used. Roofs need to be measured and cleaned thoroughly before elastomeric paint can be applied.

    Flat roof leaks, cracks, puddles? Waterproofing is needed. What should you buy? Our guide explains.

    The technology used to construct flat roofs has advanced greatly during the 1960s and 1970s. The fashionable appearance of today's flat roofs is a result of their use of contemporary materials and sleek glazing. Urban gardeners put some to use as sun terraces, balconies, and green roofs.

    Their weatherproofing technology has also advanced. Flat roofs used to leak and could only be repaired with a boiling pot of tar. These days, you can get patch repair kits, liquid rubber membranes, and quick-drying, long-lasting paint-on acrylics that you can even use in the rain.

    We enjoy opening the curtains and watching the rain fall in the winter. If the roof isn't waterproofed, a wet day can turn into a disaster.

    A Guide to Roof Waterproofing

    How to Diagnose Roof Problems

    Repairing leaks and checking for potential problems are essential steps in waterproofing a roof. Look for shingles that are missing, loose, or otherwise damaged. When the underlayment is exposed to the elements (through gaps in the shingles), deterioration occurs rapidly. Keep an eye on the flashing, which is the roofing material used to seal around chimneys, vents, and skylights. Fix any leaks or cracks in the flashing. You can't know for sure if your roof is watertight without inspecting the flashing.

    Completely Leakproof Under the Shingles

    It is important to waterproof the roof from the start, whether you are replacing an existing one or constructing a brand new one. The majority of roofs are covered in shingles, and it is important to remember that they must have a layer of something waterproof between the rafters and the shingles. An alternative roofing underlayment that is newer, lighter, and more durable is thermoplastic polyolefin. TPO membranes are permeable, allowing water vapour to escape. As a result of the roof's permeability, condensation in the attic is greatly diminished.

    Sealing the Roof Above the Shingles

    For ageing wood shingles that aren't quite ready for replacement, here's how to keep water out. Apply the water-proofing compound to the shingles by spraying, rolling, or brushing. The waterproofing oils and resins in shingles can be restored with substances that are either oil- or water-based. It is better for the environment when chemicals are based in water rather than oil. The absence of a watertight underlayment renders these compounds useless for preventing water damage to your roof.

    When a Leak Appears on a Flat Roof, How Do You Track It Down?

    In the event that you find yourself putting a bucket in the same spot every time it rains, you should look into the likely cause of the leak as soon as possible. It's best to look for the source of the leak from inside the home rather than trying to figure it out from the roof, especially if you have a flat roof.

    Find out how far away from the wall the drip in the ceiling is by using a measuring tape. Once you've climbed to the roof, remeasure the distance between the two points. That should point you in the right path to get to the meat of the problem.

    How to Perform a Flat Roof Inspection

    You will need to get up on the roof itself if you suspect an issue with the flat roof's waterproofing. But what exactly should your watchful eye be trained upon? To ensure a smooth inspection of the flat roof, remember to take the following steps.

    Be Safe

    Before you even think about inspecting your flat roof:

    1. Be sure it's absolutely secure, and if you have any doubts, get help from an expert.
    2. Use a safe, properly fastened ladder, and avoid going up on the roof itself if you have any reservations about its stability.
    3. Keep in mind that your flat roof may be highly slippery if it does not already have an anti-skid coating, so you may need to instal temporary boards.

    Time It Right

    Inspecting your flat roof after a rainy spell is ideal. This will help you spot huge puddles, or ponding, and pinpoint the source of any drainage issues.

    Inspect the Guttering

    Problems that appear to be a leak in a flat roof are often caused by the guttering, not the roof itself. This is why it's important to clean up your gutters and drains while you're up there: water can't drain properly if there's any dirt or debris in them.

    Be Aware of Potential Problems

    After the gutters have been checked, the flat roof's surface can be examined. Check for things like ponding, cracks, and splits in addition to the obvious blisters (bubbles in the membrane). The fragmented covering may now have the appearance of alligator skin. In that case, a thorough examination is required. This common problem is called "alligatoring," and it is brought on by too much sun and moisture. Without maintenance, it could crack over time.

    Exactly How Are You Going to Identify the Root of the Issue?

    Spotted something on your flat roof and don't know what it is? We can help you identify some common trouble spots, and give you tips on what to do.

    What about the flat surface of your roof, have you noticed any air bubbles there? The disease known as blistering occurs when tiny pockets of air or moisture become trapped behind the membrane. Because the sun's heat boosts the temperature of the air around the blister, causing the membrane to strain even farther, it can cause blisters to enlarge.

    However, if a blister is still intact, you should leave it alone even if it appears to be broken. If they do break, you should clean the area thoroughly and then use an adhesive patch kit like Karnak Patch N Go or a patch repair solution like Acrypol Plus, making sure the damaged area is entirely covered by the patch.


    When water sits for more than 48 hours on a flat roof, a process known as "ponding" develops. Flat roofs typically have this problem. It's possible this won't be a problem at all, but it has the potential to stress the membrane to the point where it cracks and lets in the dreaded moisture over time. Make sure the gutters are clean so water can quickly escape to avoid this.


    If your flat roof is beginning to look like alligator skin, it may be because the bitumen covering has cracked due to damage from water, debris, or the sun. Eventually, this will crack and let water in. This can be done with the help of modern roof waterproofing techniques using materials like liquid rubber or Acrypol.

    Roofing companies who are less priced but also less dependable may have omitted this step in the process. Get in touch with a roofer to examine and instal this layer if you prefer a more hands-on approach to waterproofing.

    Gutter and Other Surfaces Can Be Heated With Heat Tape

    Heat tape warms your gutters and roof throughout the winter months, preventing ice from forming in any location. Because of this, your roof will be able to maintain its integrity and will not buckle under the weight of an excessive amount of snow. This also prevents ice jams or heavy icicles from accumulating in the gutters, which would otherwise cause them to buckle or form.

    Flat Roof Waterproofing Procedures

    Step 1

    Take accurate measurements of the length and width of your roof in feet. Multiply the whole length by the comprehensive width to get the complete area.

    Step 2

    Whether you choose to use a power washer or a broom, take extra care to remove every last trace of dust and grime from your roof.

    Step 3

    After you have poured about a gallon of the elastomeric coating from the bucket onto the roof, you may begin spreading it with the paint roller. Leaving from one of the roof's corners, go counterclockwise around the entire structure. It would be impolite to tread on your coattails. Repeat these procedures until the roof is fully covered. Allow one full day for drying time after applying the last coat. Put on another coat, please.

    • If your roof wasn't built to handle regular foot traffic, you should restrict access to it. Put down temporary boards if you must walk on it.
    • To determine if the blisters or puddles are getting worse, it is helpful to keep track of their size and location.
    • Make sure there is no drooping in the joists and that the roof is level by inspecting the upstands, flashings, joints, and edge trims.
    • Finally, make sure your roof is always tidy. Water can become trapped, which can eventually destroy the waterproof barrier, if moss or algae have been allowed to grow.
