One of the most important decisions you will need to make in terms of energy savings is whether to put a TPO or other type of coating on your roof. The advantages of having an extra layer on the roof of your building starts with the protection it provides from the elements, but also the temperature changes that can affect your heating and cooling bill.
While both systems work to keep down your energy bill, they are different in the way that they are applied and used. When it comes to roof coatings vs. TPO, it is important to know what they are and how they are different.
What are Roof Coatings?
Essentially, this is an elastic coating placed on the roof which allows it to stretch and contract from changing temperature conditions. A roof coating is designed to resist the elements, physical damage and ultraviolet light (UV). It is perhaps best described as an elastic skin that resembles in some ways, though it should not be confused with deck coatings. A roof coating is not made to take the physical punishment of being walked on or driven over by vehicles like deck coatings, although they both are designed to resist and reflect sunlight. Roof coatings are made from several different types of materials that include PVC, Hypalon, spray Polyurethane foam, and even rubber.
What is TPO?
Thermoplastic Polyolefin (TPO) is a single ply roofing membrane that is primarily used on commercial structures. Over the past several years, TPO has gained considerable acceptance for its qualities in terms of durability, strength, and energy efficiency. This single ply membrane resists damage from ozone, chemical, and UV exposure year after year. TPO is installed as a solid membrane to the roof, usually by screws to secure it into place. Once completed, the TPO will help your roof resist physical damage as well as reflect sunlight.
Roof Coatings vs. TPO
Although similar in function, there are a number of differences between standard roof coatings and TPO which you will need to understand before making your final decision. Because of the materials used to make TPO it is relatively inexpensive this is one big reason why the material is so popular. TPO is also fairly easy to install that keeps the costs down as well. However, coatings such as spray Polyurethane foam are arguably better at protecting the roof because there are no openings and it is more energy efficient than TPO.
Of course, all roof coatings have their benefits and drawbacks which is why it is important to choose the right one for the needs of your building. In the end, it will come down to your budget and goals for the roof coating that you decide to choose. For many, TPO is the most economical choice because of its low cost and simple installation. However, for a longer lasting coating or for greater energy efficiency, you may want to choose another type of roof coating that best suits the need of your building or facility.
