Waterproofing Flatroofs

How to Waterproof Flat Roofs Effectively

Waterproofing significantly reduces the amount of exposure your roof gets from outside elements. These elements can cause the decking to decay. Eventually, this rotting and decaying affect the longevity of your flat roof.

Here are some of the issues that could develop if your flat roof is not properly waterproofed, as well as how to prevent them.

UV rays degradation and alligatoring
Alligatoring is the process through which debris, impact damage, water, and sunshine erode your roof membrane and form alligator hide-like cracks. If this type of damage is not addressed promptly, it may worsen, leading to cracks in your roof or the onset of leaks.

Pooling
When water pools on your roof, it signifies that your drainage system or slope is failing to drain water off the roof. Your roof membrane may become weak as a result of this. This could cause major damage to your building in the long run.

Why Waterproof?

Cost savings
A waterproof membrane for your roof not only reduces wear and tear, but it also saves you money in the long term because it is much less expensive than a complete roof renovation. You’ll save money as well because roof repairs will be less frequent and maintenance expenditures will be reduced. You’ll save money in the long run by extending the life of your current roof.

Longevity
Waterproofing decreases the possibility of severe damage. You’ll have an extra layer of protection against wear, decay, and leaks caused by rain and wind if your roof is protected by a waterproof membrane. It also reflects sunlight, decreasing the impact of high heat and light on your roof.

Energy efficiency
Because waterproof membranes reflect heat and sunlight, you’ll save money on air conditioning in the heat by keeping the temperature of the structure consistent.

Lower humidity
A waterproof roof coating prevents water from leaking into your structure. Waterproofing reduces the humidity levels in your building while also preventing the growth of mold.

Low maintenance
A waterproof coating is much simpler to maintain and repair than your existing roof infrastructure. When maintenance and repairs are necessary, they are generally much quicker to perform than on a conventional roof alone. The majority of repairs will simply have to be made to the waterproof coating rather than the roof itself.

Convenience & comfort
Waterproofing your flat roof is time-saving and a less intrusive technique of maintaining or repairing your roof.

Ways to waterproof your roof

Repair Kit
Repair kits, often known as patch kits, are great for repairing minor areas. In most situations, dedicated repair kits developed by the manufacturers are available for your specific roof. Patch kits are fantastic since they can be used and applied with little to no effort. They’re great for new DIYers seeking for a quick fix, but it’s vital to note that they’re only useful if the roof is already waterproof.

Sealant
This is usually for quick fixes and smaller roof surfaces, even though you can equally use it to waterproof an entire surface. What makes sealant one of the best ways to do this kind of work is the fact that it’s a simple and easy solution and everyone can do it. Depending on the layering, a sealant can be more than just a quick fix and it can last you for quite some time. However, if you’re looking for something that’s just as durable but even more long-lasting, liquid rubber is certainly the way to go.

Reinforced Bitumen Membranes (RBM)
Most residential property owners use reinforced bitumen membranes to waterproof their flat roofs. The
the process involves bonding together two to three layers of bitumen that are laid across the full surface of the flat roof. A polyester carrier is then combined with this coating to create a waterproof material. In order to attach this waterproof bitumen membrane to your flat roof, you can pour and roll or pour hot bitumen in front to seal the material to the roof. Cold application method can also be used where a cold adhesive is used to bond the material to the roof. Other methods of attaching the RBM to the roof include using a gas torch and self-adhesive.

Liquid Rubber
Liquid rubber is a great waterproofing solution for both large and small areas. Also, it’s quite easy to do, so anyone regardless of their skill will be able to do this quite efficiently. As opposed to patch kits, liquid rubber can be used on brand new roofs to make them waterproof. Liquid rubber is excellent for waterproofing roofs from the outset. In some cases, priming the surface before applying the rubber is required, but this is not always the case. In any case, you’ll want to apply a thick coat of liquid rubber to the roof and spread it evenly throughout the entire surface. This will result in a lovely, elastic coating that will last a long period.
