TPO Roofing - Everything You Need to Know
When it comes to the building and construction industry, technology is changing things for the better. For example, right now, it is possible to get yourself a damn durable, aesthetic-looking roof without breaking the bank.
One type of roofing that is rising in popularity, especially on commercial buildings is TPO roofing. TPO roofing enthusiasts are lauding this roof type saying it is cheap to install, durable and eco-friendly.
What is TPO Roofing?
TPO roofing is a type of single-ply membrane roofing where a thermoplastic polyolefin rubber membrane is used to cover the surface of a flat roof.
A TPO roof is recognizable by its reflective look of bright white color. It is mostly seen in big commercial facilities. It is one of the two types of single-ply membrane roofing, the other being EPDM roofing where Ethylene Propylene Dine Terpolymer (EPDM) is used.
Single-ply membrane roofing is a type of roofing widely used on commercial buildings. In this type of roofing, rubber sheets and synthetics are chemically adhered, mechanically fastened or ballasted to insulation to achieve a layer of protection on the building.
How are TPO Roofing Products Made?
Two things make up a TPO roofing system, a single layer of synthetics and reinforcing scrim. The Thermoplastic polyolefin membranes are manufactured in sheets of sizes 10, 12, or even 20 feet wide, then rolled up and transported to the site of the commercial facility for use.
Do not be confused by the inclusion of the word 'plastic' in the term thermoplastic. TPO is a type of rubber roofing crafted by blending ethylene-propylene rubber and polypropylene.
Pros and Cons of TPO Roofing
What has made TPO a favorite for use on commercial properties is it's a thin roofing material suitable for covering flat roof surfaces. Its natural reflective surface also puts it in front of other roofing materials. Approximately 40 percent of the commercial roofing market is taken up by TPO, which is according to the National Roofing Contractors Association (NRCA). Here is a quick look at the pros and cons of TPO roofing:
Advantages of TPO Roofing
Currently, TPOs materials are among the best roofing materials in the market. It is also the best quality form of single-ply membrane roofing, costing less than EPDM and other forms of rolled rubber roofing. This, added to the fact that the roof decreases house heating during hot weather, makes TPO a money-saver.
Say hello to reduced house cooling bills during those hot summer months with TPO roofs bright white reflective surface. This surface turns away plenty of the sun's UV rays keeping your facility cool for the comfort of the occupants.
During the manufacturing process, fire-redundant chemicals are added to TPO and EPDM membranes to achieve class A fire-rating. The risk of the roof catching fire is, therefore, reduced.
Flexible Installation Process
With single-ply membranes, the choice of installation lies with the customer. TPO membranes can be mechanically fastened directly to the roof decks or heat welded in place. It can also be chemically attached to insulation.
When installed in place properly, TPO roofing can serve you for up to 30 years. The blend of rubber and synthetics is corrosion resistant and does not break down easily when in contact with weather elements and other materials too.
TPO is also low-maintenance. It does not encourage mildew or algae bloom, and there's no need for pressure washing.
Disadvantages of TPO Roofing
TPO is inexpensive and bright looking, but that doesn't mean it is not without its share of troubles. In fact, sometimes, the cons tend to outweigh the pros. Most of these drawbacks stem from the manufacturing style and poor regulation of the damn industry. The negatives of TPO roofing include:
Lack of Design and Manufacturing Standards
Because the industry is not standardized, different manufacturers offer TPO materials of varying quality for the same price. It is easy to end up with a poorly constructed TPO membrane when for the same price, you could have chosen a high-quality roofing material.
In another way, TPO manufacturers also trick customers into paying more for thicker membranes, when thickness has very little to do with durability. All TPO materials wear out the same irrespective of thickness.
Changing TPO Ingredients
The ingredients used to manufacture TPO membranes keep changing. This makes it impossible to ascertain how long TPO roofs will last. For example, they have recently started laminating the top part, but the side effect is lamination introduces weak points making the membrane vulnerable to cracks. It also causes the material to shrink.
Alrighty, loves, there you go; are you shopping for TPO roofing materials?
