Choosing the Right Roofing Material and Coating

When it is time to replace your roof, you need to consider two aspects of the job: the materials and the coating. The right coating can help your roof last even longer. Both items can also make your home cooler and more energy efficient. Here is a look at some of the choices you have and when each are best suited.

Should You Repair or Replace

Before deciding on which material is best for your roof, you need to determine if you will be repairing or replacing it. If your roof is less than half way through its expected life, repair is probably the best choice. As it nears its end of life, replacement may be a better option for cost savings.  Of course, this also depends on how much damage has been sustained or how big of an area needs to be replaced. You must also consider your budget because replacement can vary widely in price, depending on the type of roofing material you use.

Types of Roofs

The two main types of roofs used on Hawaii homes are asphalt and rolled roofing. Asphalt shingles are often seen on roofs with a higher slope while rolled roofing is preferred for many roofs with low pitches.

When looking at cost, the warranty will play a big role in how much you pay. You must compare that price with the length of time you plan to spend in the home. For instance, a roof that comes with a 50-year warranty will most likely be more expensive than one with a 30-year warranty. However, you won’t have to pay for the cost of replacement for many years, perhaps ever, if you plan to stay in this house for a long time.

Color is also an important aspect in choosing a roof. It is usually best to stick with light colors to keep your home cooler. According to tests done by experts, the difference in temperature between a light roof and a dark one can be more than 20 degrees. On a hot summer day, that can have a big impact on your comfort level and your utility cost.


What makes your roof last even longer is choosing the right coating. The two most popular options are silicone and acrylic. Silicone is not water-based, which makes it preferable for low roofs that often have standing water. This coating doesn’t wash off and have a long life. You can even find warranties for up to 50 years.

Acrylic is ideal when you prefer a colored roof. It also reduces the temperature of your roof to cool off our home. Ceramic coating is a third option and functions much like acrylic. It can be used on asphalt, aluminum, metal and other types of roofing materials. When replacing your roof, consider the best product for the type of roof design you have, the
importance of aesthetics like color and the ability to lower your interior temperature. Don’t forget to take the same effort with choosing the best coating to protect your new roof.
