The roof is an essential part of a property but one that most homeowners and business owners neglect; many rarely ever go up to it. But ignoring your roof doesn’t mean it doesn’t exist. Like any other part of a property, it needs regular maintenance. Particularly for homes with a flat roof in an area, that experiences a lot of rainfall because the water will stagnate on the roof and potentially damage it. To avoid this, you need to waterproof your roof.

So, how do you waterproof a flat roof, you ask? With two simple and effective methods.

Two methods for waterproofing a flat roof

While there are two ways to waterproof your flat roof, you need to determine which of the two is the best for your home. To do that, you need to consider the construction of the roof, its size, and the weather it has to endure. Then select one of the following waterproofing methods:

Elastomeric Coating

Elastomeric coating is a liquid coat you can apply on concrete, membranous, and metal roofs that reinforce it, giving protection from elements such as water. The liquid is like paint but serves as an added layer of protection for your flat roof. It is commonly used for residential homes. The process of applying the coating is simple and requires you:

  • Measure the surface area of the roof. For this, you need to measure the overall width and length and multiply the two. The surface area will tell you exactly how much coating will be needed.
  • Before you can start applying the coating, you need to ensure that your roof is clean. You can sweep it with a broom or use a pressure washer to remove any dirt. Give the room time to dry before you start applying the coating.
  • The application process is a lot like painting, you can pour some elastomeric coating on the roof, and with a roller spread it out. You should start from the corners and walk backward so you don’t end up stepping on the coat you’ve applied.

Single-ply membranes

For larger homes, apartments, and commercial buildings single-ply membranes are more efficient as the surface area of the roof is bigger. The single-ply membrane is a sheet that covers the entire area of the roof. To ensure the sheet remains on the roof, plastic fasteners are screwed through, for reinforcement.

Either one of the two methods we have mentioned can increase the lifespan of your roof and reduce the chances of water leaks through the ceiling from heavy rainfall.
