This is the most common type of roof coating; 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.


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.


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 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.

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.
