Roof Coating Buying Guide

Buying Guide - Roof Coating

Indeed, there are several reasons why you should only opt for the best. Before you start choosing a product, you have to understand the coating technology it is equipped with. In this guide, we will find out some of the factors that you have to consider when buying a roof coating.

Provides Resistance

First, you should know the type of coating best suited for your roof. It is worth noting that not all roofs are the same. The same is true with the formula the coating is made of. However, your roof needs one thing in common, and that is to have resistance capacity.

With this, you will be certain that it can face different conditions. Well, it cannot be denied that the roof is exposed to various challenges – UV rays, rain, and more. If you apply high-quality and durable coating therein, you won’t have to worry about anything.

Adjustability

Aside from the quality of the roof coating, you also need to consider a product that ensures optimum adjustability. For sure, it is all worth it if the coating is just right to your roof. Given that not all roofs are the same, there’s a need for a coating to suit whatever materials you have.

Reflectivity

This aspect is very crucial and is linked to energy savings. If it produces high reflectivity, the roof will most likely get cooler, thereby reducing energy cost.

It is very important, especially during the hot weather as it reflects solar radiation. Through this, the heat absorbed by the roof from the sun will be reduced. And you know that if it happens, you won’t be needing to consume more electricity to make the place cooler.

Types of Roof Coating

Different types of Roof Coating

One of the most complex constructions in a building or house is the roof. Before you should apply a coating, you have to understand the roof itself first. In this section, we will find out the different types of roof coating. Through this, you’ll know that you just can’t dwell on any product. Let’s dig further.

Acrylic

This is the most common type of roof sealant; it is available in solvent and water-based products. But its notable feature is its flexibility. This coating is ideal for various weather conditions – rain or shine.

Polyurethane

Although it typically comes in solvent formulas, there are two types of polyurethane roof coatings – aliphatic and aromatic. The latter kind is not ideal for hot weather conditions since it is not excellent in handling UV rays.

But what is unique about this is that it has the capacity to take a lot of damage and friction. This only means that it is a good choice when the roof is susceptible to harsh weather conditions. Also, it is a good idea when the roof is exposed to hail or maybe if people use to walk on it.

Silicone

If you are living in the city or town that rains a lot, then you’re already familiar with this kind of roof coating. Well, it is the best option when it comes to extreme wetness. Not only that, but the best silicone roof coating can also deflect UV rays, making it ideal for hot conditions too.

More excitingly, using this coating can make your house cooler. Why so? It has UV reflecting power, especially useful during the summer months. Perhaps, the major drawback of this kind is its price. It’s very expensive. Anyway, you can reap the utmost benefits when you opt for this product.

Rubber

If you compare other roof coatings in the market, you will most likely find this one expensive. Just like the previous type, it can be pricey, but very effective in ensuring the durability and safety of your roof.

This means that whatever weather conditions your roof will be exposed to, it won’t cause you much of a problem. It is sure to provide you optimum protection that you deserve.

Also, being made of rubber means that it can be flexible. With this, you can expect maximum sturdiness and longevity. It is also perfect for protecting your roof from UV rays as well as infrared radiation.

Sealant Tapes

One of the simplest kinds of roof coating is the sealant tape. Its application is very easy; all you have to do is to place it in the spot needed to be covered. But then, you can’t expect optimum durability and efficiency with this one. Yes, it is the cheapest option, but it cannot adhere to other surfaces like wood.
