Roof Surface Treatment – Coatings for Flat Roofs

If you happen to be a homeowner or an owner to a business premise having a flat roof installed on your building may result in complicated issues and these might be too hard to fix if you don’t have the right knowledge. Even hiring any roofers won’t necessarily fix your problem, as the roofer needs to know in great extent pertinent to roof surfaces and how they react with other layered roofs.

Repairing a flat roof is perceived as a complicated task mainly due to the fact that it’s not easy to detect the presence of any leaks on it. A leak that occurs in a flat roof may originate from a spot that is showing no signs of leaking. In other words, if you see a pool of water in a spot, it doesn’t mean that you can find the leak right on that spot. When leaks happen, big pools of water may be formed at some surface areas of your roof, and if you don’t fix them quick the damage can spread to other parts of your home apart from your roof.

You can solve this problem through a number of strategies. If budget is not your concern, you can choose the expensive way which is to bring down all the damaged surfaces. As this is a very costly option, it’s not the most popular. In reality the lifespan of these roofs can be prolonged as long as they receive regular maintenance and care.

The smartest technique of extending the lifespan of a flat roof is by applying a protective coating on top of the damaged surfaces. You can find several options for this. Common options may include asphalt, polymer and elastomeric. All are great to use but elastomeric provides more satisfactory results than the rest.

Asphalt coating is found in the form of liquid, and its color is black and petroleum-looking. When buying asphalt, find a product that comes with a warranty. It should also contain embedded fibers made of fiberglass. Asphalt coatings are only allowed to be applied on top of a roof that is also made of asphalt; for instance, felts and altered bitumen. You can try applying asphalts on metal, but in most instances the application won’t work well. Some coatings are added with flakes of aluminum to provide sun reflecting ability to the roof so that its temperature can be lowered without relying much on cooling devices.

Elastomeric coatings are typically made of rubber and they are sold in the form of liquid. Typically, they have white as their primary color. You can add different colorants to create a new color tone. Elastomeric is higher in quality compared to asphalt due to its stretchable nature which can reach up to 600%. Elastomeric coatings can be used to solve a number of roofing problems as they’re applicable on metal, asphalt, concrete and rubber. White elastomeric coatings are able to lower the temperature of the roof and this helps you save on power consumption.

Over a period of time, the cost of installation and buying the elastomeric coatings can be covered effectively by way of energy saving.

The two options above can provide you with a leak-free roof provided that proper installation is done. The coatings can’t be applied on their own, you must go through a tedious process before the application can be done. Some of the tasks you need to do beforehand are fastening each fasteners and make sure it’s perfectly sealed, reinforcing the seams, checking and reinforcing the flashing, and cleaning the surface of the roof where the coating will be applied.

Many things need to be considered in the process of selecting the right coating for your roof. If you are not confident due to any reasons at all, hiring the right roofer to get the job done is crucial. Make sure you inform the roofer to abide by the proper steps and plans in ensuring the perfect seal for your roof.
