Flat roofs don’t drain like sloped roofs, but there’s a simple solution. Two coats of elastomeric coating prevent water damage and heat loss by insulating the roof. Before applying elastomeric paint, measure and clean your roof for a durable coating.
Flat roof leaks, cracks, puddles? Waterproofing is needed. What should you buy? Our guide explains.
The technology behind flat roofs has come a long way since the 1960s and 1970s. Glazing and contemporary materials have made flat roofs a design option for today. Certain ones are put to good use by urban gardeners who put them to use as terraces, balconies, sun and green roofs.
Their weatherproofing technology has also advanced. There was a time when leaks in flat roofs could only be remedied with a boiling pot of tar. These days, you may find liquid rubber membranes, patch repair kits, and quick-drying, long-lasting paint-on acrylics that can even be applied in the rain.
We enjoy having the curtains open in the winter so that we can observe the rain outside. If the roof isn’t waterproofed, a wet day can turn into a disaster. We are safe from heat, lightning, rain, and radiation thanks to the roof. The roof must be constructed and painted with top-notch water repellent materials. The following are methods of waterproofing your roof and preventing the intrusion of water from rain and snow.
At Hitch Property Constructions, we offer the best range waterproofing services to rectify your water issues.
Do I Need A New Roof Or Can I Repair This One?
It all depends on how old the roof is and how well it’s held up. Re-roofing might not be required if the damage to the roof is minimal. Most homeowners should be able to handle simple repairs themselves with the products available today. You can buy yourself some time to figure out what to do because even patch repairs are robust and long-lasting these days.
The more thorough waterproofing materials offered by Roofing Superstore are both simple to use and highly durable. A coat of Acrypol 15 lasts for 15 years and can be applied onto any flat roof.
When do you plan to replace your roof? Your flat roof may need to be re-roofed if the insulation value drops too low. If condensation is prevented in the room below, the insulation may also save heating costs. A new roof can strengthen the structure of your flat roof, allowing you to host rooftop parties and garden parties with ease.
Roof Waterproofing: How To Do It
Troubleshoot Your Roof
Fixing leaks and checking for damage are necessary steps in waterproofing a roof. Find and fix any shingles that are missing, loose, or damaged. When the underlayment is exposed to the elements through cracks in the shingles, it quickly deteriorates. Look at the flashing that seals the roof around the chimney, vents, and skylights. Fix any leaks or cracks in the flashing. You can’t ensure your roof is watertight and leak-free unless you inspect the flashing.
Waterproof Under The Shingles
The roof must be waterproofed from the start, whether it is being replaced or a new roof is being constructed. 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. Roof underlayment made of thermoplastic polyolefin is more recent, lighter, and more durable than its predecessors. TPO membranes are permeable, allowing water vapour to escape. Condensation in the attic is decreased by the roof’s breathability.
Waterproof Over The Shingles
Fixing worn wood shingles without replacing them: waterproofing techniques. Waterproofing compound can be applied on shingles in a variety of ways, including spraying, rolling, or brushing. Restoration of the oils and resins that keep water out can be accomplished with either oil- or water-based chemicals. Compounds that are water-based are better for the environment than those that are oil-based. It stands to reason that if your roof doesn’t already have a waterproof underlayment, these compounds won’t do much to help.
How Do You Determine Where A Flat Roof Leak Comes From?
If you discover that every time it rains, you must move a bucket to the same spot, you may want to look into the possibility of a leak. 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.
Determine how far away from the nearest wall the ceiling drip is by using a measuring tape. Once you have climbed to the roof, remeasure the distance between the two points. That should point you in the right path, right to the meat of the problem.
Checking Your Flat Roof: A Guide
If you suspect a leak in your flat roof’s waterproofing, the only way to find out for sure is to get up there and take a look for yourself. But what exactly should your watchful eye be trained upon? A successful inspection of the flat roof requires that you adhere to the following procedures.
Stay Safe
Check these things first before you try to evaluate your flat roof:
- If you have any doubts about whether or not it is safe to proceed, you should bring in an expert.
- If you must use a ladder, do so only if you are confident in its stability, and never step directly onto the roof itself.
- Keep in mind that a flat roof without an anti-skid coating could potentially be highly slippery, so you might need to install some boards as a precaution.
Inspect The Guttering
It’s not uncommon for a flat roof’s gutters to be at fault for what appears to be a leak. This is why, before you head up there, you should check to see that all of the gutters and drains around your property are clean.
Perfect Timing
Flat roofs should be inspected once a rainy spell has ended. This will help you find any spots where water collects to form ponds and pinpoint any drainage issues.
Be Aware Of The Issue To Watch Out For
After the gutters have been checked, the flat roof’s surface can be examined. blisters, You should inspect the membrane for signs of damage, such as bubbles or ponding, fissures, or splits. A probable explanation is that the covering has come apart and taken on a pattern reminiscent of alligator skin. If this is the case, make sure you double-check everything. “Alligatoring” describes a common condition brought on by too much sun and humidity. Without maintenance, it could crack over time.

Alligatoring
If your flat roof is looking like an alligator’s skin, it could be because the bitumen covering has split due to damage from water, debris, or the sun. This will break down over time, allowing water to seep through. This can be done with the use of modern roof waterproofing techniques, such as the use of liquid rubber or Acrypol.
Ponding
When water pools for more than 48 hours on a flat roof, a condition 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 breaks and lets the dreaded moisture in. Making sure the gutters are clear will allow water to quickly drain and avoid this problem.
Blistering
When you look at the smooth surface of your roof, do you perceive any air bubbles? The condition known as “blistering” occurs when air or moisture bubbles form behind a membrane. A blister’s size can be exacerbated by exposure to sunlight, as the sun’s heat elevates the temperature of the air around it, causing the membrane to stretch even farther.
Despite the fact that blisters may appear to be fragile, you should leave them alone if they are still intact. If they do break, clean the area thoroughly, then use an adhesive patch kit or a patch repair solution like Acrypol Plus, making sure the injured area is entirely covered by the patch.
Diy Steps For Waterproofing Your Rook
Take Out All Dead Branches And Leaves.
Damaging rains can lead to roof failure if you have debris like dead leaves or branches accumulating on your roof. If you live in a dry region, like Texas, raking up dried, dead leaves might reduce the unsettling possibility of a wildfire starting on your roof.
Clean Up Trees Near The Roof
Fallen limbs and other debris can make your roof vulnerable to damage from bad weather. If these branches were to fall due to weather conditions such as high winds, ice, hail, or snow, it might cause costly damage to your home. If you keep your trees pruned close to the roof, you may rest easy knowing that your house is safe from falling branches.
Any Curling, Missing, Or Damaged Shingles Should Be Replaced.
A single curled shingle can create a leak in the roof’s underside. If this water seeps inside, it can cause the formation of mould and mildew, which will require further repairs to your home. In addition, wind might blow off the roof if the shingles are loose.
An expert roofer will be able to tell you the state of the rest of the shingles in the area, even if you can replace one or two on your own. In this way, they can save you money by extending the life of your roof rather than replacing it entirely.
Make Your Attic More Insulated.
In order to prevent the roof from warping or cracking due to extreme temperature changes, proper insulation should be installed in the attic.
Put Seam Tape In The Seams.
When repairing seams in a concrete roof, seam tape is a great tool to have on hand. Water can be kept out of the building by using seam tape on the exterior roofing. It’s important to press down firmly after applying it to ensure a full seal.
Apply A Water-Resistant Layer.
It’s possible that this step was neglected if you choose a cheaper roofing company that is also less dependable. Hire a roofer to examine and install this layer if you prefer a more hands-on approach to waterproofing.
Gutter And Other Surfaces Can Be Covered With Heat Tape.
Using heat tape on your gutters and roof throughout the winter will keep them from freezing over. As a result, even if a lot of snow falls on your roof, it won’t give way. If ice were to build up in the gutters in the form of ice jams or icicles, the gutters may potentially buckle under the weight of the ice.
The Most Effective Way To Waterproof A Flat Roof
STEP 1
Make sure you get accurate measurements of your roof’s length and width in feet. Multiplying the entire length by the entire width yields the total area. This method can be used to determine the area in square feet. Get in touch with the helpful staff at your local hardware store and ask how many buckets of the coating will be required for your roof’s dimensions.
STEP 2
Whether you choose to use a power washer or a broom, you should be sure to remove every last bit of debris and dust from your roof. In an emergency, you can clean the roof with a solution of 1 quart of trisodium phosphate and 5 gallons of water. The roof must be completely dry before the coating can be applied.
STEP 3
After about a gallon of the elastomeric coating has been emptied into the bucket and spread across the roof, you can start rolling it on with the paint roller. You should take a walk counterclockwise around the roof, starting at one of the four corners. Keep your coat off the floor! Keep going until the roof is fully covered. Allow a full day for drying time after applying the last coat. Put on a second coat.
What Is The Best Waterproofing Paint To Select For The Roof?
Epoxy Waterproofing Paint
Poly-epoxides, also known as epoxy paint, are created from resins. On damp roofs, this is an effective waterproofing paint. Paints made from epoxy resin resist water. This coating will prevent water, chemical, and strong acid damage to your roof. Compared to other waterproofing treatments and terrace paint, the Nippon variety is far more substantial. To keep the rain and snow out of your home, we have developed a number of epoxy-based waterproofing products.
Masonry Waterproofing Paint
Tile and tile roofs are painted using a combination of ceramic and latex paints. One of the most popular roof waterproofing paints in the world. This roof coating is widely used since it quickly absorbs liquids and can be applied to any roof (water, chemicals). The roof is protected from precipitation thanks to the masonry paint used for waterproofing. Roofs, concrete blocks, bricks, and stones are all protected from rain and snow by this paint. This paint doesn’t just do a good job of keeping water out, but it’s also safe for the environment. Because there is no lead in this paint, that’s why. There won’t be any algae or fungi on the roof because of the fungicide and algaecide in the masonry paint.
Acrylic Waterproofing Paint
Roofs and terraces made of rectangular blocks are best waterproofed with acrylic paint. Your roof’s durability and water resistance will be greatly improved if you use this waterproofing solution in conjunction with a primer. A roof coated with an acrylic waterproofing solution that contracts when it rains helps to keep water off the structure.
In comparison to other waterproofing solutions, acrylic paints are user-friendly and safe. One can use a roller, a spray painter, or a brush to apply acrylic paint. This roof sealant dries quickly and leaves no unpleasant odour.

Advice For Helping To Avoid Flat Roof Leaks
- Flat roofs should be inspected at least twice a year. There are two good times to do it: in March before spring begins and in November after winter has ended.
- Keep anyone from going up on your roof unless it was built for that purpose. It’s best to use temporary boards if you have to walk on it.
- Keep track of the location and size of any blisters or puddles so you can tell whether the problem is growing worse.
- Make sure there is no drooping of the roof at the joists and inspect the upstands, flashings, joints, and edge trims.
- Finally, make sure your roof is always tidy. It is possible for the waterproof barrier to be damaged by accumulated moisture if moss or algae are allowed to grow.
Preventative maintenance is always preferable to repair for flat roofs. Therefore, address minor issues before they escalate into major, costly ones.
