Is TPO roofing good?

TPO roof installation

TPO roof installation

Roofing on any structure is important. For your home, it protects your family and belongings. For a business, it protects assets, inventory, and occupants. So, when looking to replace the roof, which is better, TPO roof vs PVC, is TPO roofing material the best to cover your commercial structure’s roof? 

There are several choices for commercial roofing these days, some better than others, all depending on the climate and environment of the structure. When you take the time to look closer at TPO roofing material and the TPO roofing details, you’ll understand why it is the better choice for some structures than others. 

What is a TPO roofing system? 

TPO is an abbreviation for thermoplastic polyolefin. It is one type of membrane used for single-ply roofing application to cover a roof’s surface. The name is perhaps misleading, TPO isn’t plastic, but a combination of different rubbers, usually ethylene-propylene and polypropylene. This combination of rubbers makes TPO roof material a durable material.

For commercial structures, TPO roofing material is fast-growing for use on commercial structures.  Why? Because it is durable but inexpensive. It is a reflective material that eases the strain on a commercial structure’s HVAC system, thus saving money on energy use. 

What is the difference between TPO and PVC roofing? 

The original weldable roof material, PVC, (Polyvinyl chloride) is a solid plastic material rendered from vinyl chloride. They add phthalates to make is flexible and softer. PVC is the original weldable sheet and has a comparable reflectivity to TPO. 

The concern has always been, as the plasticizers migrate from the sheet, what happens to them? TPO roofing material was considered a flexible material and has proven over time that is improves steadily regarding weathering resistance. Still, PVC has remained to be a viable alternative. 

When the two are compared between Accelerated Weathering vs Heat Aging, TPO wins hands down. TPO roofing material has stronger resistance against breaking and tearing than PVC. However, PVC has a strong resistance to chemicals and doesn’t absorb greases or oils, which makes it more appealing for a commercial structure with a grease trap, such as a restaurant. PVC is more flexible, a preference of contractors installing it. While TPO roofing material requires a hotter temperature for welding, both materials rate high in weldability. 

How do you clean a TPO roof?

TPO roofing material is an investment for the owner of a low-slope roof building. The investment doesn’t stop after the installation though. The maintenance after installation is important to get the most lifespan from TPO roofing as possible, including cleaning it. A regular maintenance schedule should include cleaning for the following reasons:

  • A clean TPO roofing material covered surface will provide maximum reflectivity, giving you the best energy benefits.
  • When debris and dirt are left on TPO roofing material covered roofs, it becomes a feeding ground for algae, plant growth, etc.
  • Keeping the accumulation of plant growth and other food sources cleaned will minimize a breeding ground for birds and pests.
  • Keeping chemicals cleaned off, the TPO roofing material won’t be harmed, extending its lifespan

The following precautions are recommended by professional contractors that install TPO roofing materials on commercial structures to get the longest lifespan possible:

  • To prevent possible damage to the roof’s integrity, only experienced professionals should be permitted access to the roof.
  • Caution should be exercised when the roof has the possibility of being wet due to the TPO roofing material becoming slick.
  • Never walk on a roof with TPO roofing material when the cleaning solution is present – it must be rinsed thoroughly first.
  • Where the run-off and exterior facades may come in contact, test a small area for adverse effects to the facade that the cleaning solution may create.
  • Create accommodations for cleaning solution run-off to avoid possible damage to the facade, plants, and groundwater contamination
  • Always comply with water run-off requirements by local, state, and federal laws.

Cleaning schedule of a low-slope roof with TPO roofing material is determined by factors like the environmental contaminants and rainfall frequency, the tendency of accumulated dirt and dust, and the drainage characteristics. The cleaning process requires using a long-handled, soft-bristled floor broom and a cleaning solution of a household detergent that is mild and non-abrasive with clear, clean water.

Can you coat a TPO roof? 

Yes, using only a water-based acrylic TPO roof coating available through the roofing industry, typically by way of a commercial roofing contractor. It adheres with tenacity when applied directly to existing TPO roofing material and eliminates any need to use a primer or an etching rinse.

What can I use to seal a TPO roof? 

There are specific products on the market to seal commercial building’s TPO roofing material, you should not use any type of sealant that isn’t specifically for TPO roofing material. A professional roofing contractor will have this sealant on hand.

To recap facts and information we have provided in this article about TPO roofing material.  

TPO roofing benefits 

The biggest positive of TPO roofing material for a flat roof is the lower cost compared to other materials available. Another positive the reflective white color doesn’t allow heat to build up inside the structure. Installation is another benefit because of the ease and simplicity of using direct attaching adhesives or fastened to the roof deck. Around the chimneys, HVAC or plumbing protrusions, it can be heat welded. Last, but not least benefit is TPO roofing material is corrosion resistant and doesn’t encourage algae and mold growth, nor does it have to be cleaned by pressure washing.

TPO roofing issues

There are more cons than positives when it comes to TPO roofing materials. Because it is an inexpensive material, there are many manufacturers of this product, which means the quality is can vary. It comes in different thicknesses, but that doesn’t mean the thicker the better and many consumers will purchase thinking the thicker is the better.

Because they laminate the top layer of TPO roofing material, it can last 10 to 20 years with proper care and maintenance, so buying the thicker won’t make any difference in longevity. However, the laminating creates weak points that allow cracks, craze, deterioration, and shrinkage. The cheaper the TPO roofing material, the more prone to that happening.

TPO roofing material is available in small widths, but this will create seams every six to eight feet. Every seam is a possible leak because the membrane will contract and expand with the temperature. Every contraction, every expansion, leaves it subjective to separation and leaks.

How Many Years Does an Asphalt Roof Last?

Asphalt roof repair is a critical part of home ownership

How Many Years Does an Asphalt Roof Last?

If you are purchasing or selling a house that has an asphalt roof, it will be important to understand the current condition of the roof, and how many years are remaining in the roof’s life. This will help you budget for an appropriate roof replacement whenever it is necessary. With proper care and attention, an asphalt shingle roof can last thirty years. Depending on the prevailing weather patterns and amount of roof maintenance, this number can lower to fifteen or twenty years.

Is An Asphalt Roof Good?

There are many advantages to an asphalt shingle roof. Please browse through the following list to find out more!

  • Lightweight. Asphalt shingles add a limited amount of weight to a roof. In fact, most homes are already equipped to have them installed. Heavier roofing materials, such as slate, add a lot of weight, which stresses the building’s supports. Asphalt shingle roofs won’t require additional structural support.
  • Affordable. One of the principal reasons why asphalt shingles are so popular is because they are one of the most affordable roofing options available on the market.
  • Efficient installation. Many roofing companies are very well-versed in shingle roof installations. Asphalt shingle roofs are renowned for having a very easy and convenient installation.

Can You Paint Asphalt Roof

While it is possible to paint asphalt shingles, many roofing professionals advise against this process. This is because the roof, being completely exposed to the elements, is much more prone to damage than the rest of the home. Peeling paint is never a good look for a home. If indeed the process must occur, the paint that is generally recommended for the process is a high-quality, 100 percent acrylic latex paint with a flat finish. 

What is Asphalt Shingle Roof

An asphalt shingle roof utilizes asphalt shingles for weatherproofing. Asphalt shingles are resistant to water and are a popular and affordable style of roofing. Asphalt shingles have been around in America since the turn of the 20th century. They were first invented in 1901 and generally used in America by the year 1911. Over the years, asphalt shingles have been adapted to become stronger and more resilient to the weather than earlier prototypes. Many different types of asphalt shingles have developed, including three dimensional and laminate shingles. 

Asphalt shingle roofs are different from asphalt rolled roofs

What is a Rolled Asphalt Roof

This style of roofing material is called either asphalt roll roofing or asphalt roll membrane. This particular roofing material is in demand for buildings that have a low-slope roof pitch in the United States. While asphalt rolls are composed of the same materials in asphalt shingles, they are applied differently. Roll roofing is applied parallel to the eaves from the bottom of the roof upwards. Each roll overlaps the next, in the same manner as shingles. Roll roofing is lighter than shingles and is thought to be an inexpensive, temporary material. Its main uses are for outbuildings, on flat roofs on houses in the UK, and as backup water catching and wind stopping layer.

What is TPO Roofing?

A TPO Roof Installation in Progress.

The Advantages of TPO Roofing

As a business owner, you may have heard the term TPO roofing kicked around by commercial contractors and roofers but very few people outside of the roofing industry know what it actually is. However you may want to take some time to familiarize yourself with this material as it could be the answer to some of the building problems you have been encountering. First off, TPO stands for thermoplastic polyolefin.

It is a roof coating that is applied mainly to commercial and industrial type roofs. TPO coating usually comes in rolls and despite the word “plastic” being used in the name, the rolls are actually made out of rubber. In order to provide more protection to the roof itself, the rubber sheets that TPO coatings come in will usually feature a specially laminated upper layer. 

So why would any business owner choose to install TPO roofing over other traditional kinds of commercial roofing like ethylene propylene diene monomer? Take a look at the following list of advantages that TPO roofing brings to the table:

  • TPO Roofing is Economical – One of the main reasons that TPO roofing is emerging as a business owner’s choice is because of the fact that it is so affordable. You can buy TPO coating by the foot and it will more often than not be much more affordable than other kinds of commercial roofing material.
  • TPO Roofing is Great for The SoCal Sun – Another reason why people are shying away from more traditional types of commercial roofing like tar paper is because dark roofing materials like tar paper and asphalt absorb heat. This can make it difficult to cool a large commercial or industrial building. TPO roofing will usually come in white which means it reflects the intense SoCal sun rays as opposed to absorbing them. This makes it much more economical to cool a large building.
  • Long Warranties – Since TPO roofing is so durable and needs little in the way of maintenance, manufacturers typically offer warranties for the material that can last for up to 30 years.
  • Good Wind Ratings – TPO roofing is usually made to achieve high wind ratings which means two things; one, that it will hold up in high winds like the Santa Anas that we get here in SoCal; and two, it may very well lower the property insurance rates for your building. 

Installing TPO

Another reason why TPO is becoming more and more popular is that the property owner has options as to its installation. This allows for more flexibility as opposed to other roofing materials and allows the owner to choose at his or her discretion. Here at Weatherline Reroofing & Repairs Inc. we are capable of installing TPO roofing in the following methods and others as well. To learn more about our TPO roof installation service, please give us a call at (714) 731-3425 !

Mechanical Installation 

Mechanical attaching is preferable when time is a factor. This is a very quick method of TPO roofing installation and involves securing the rubber sheets to metal plates that are fastened to the roofing structure itself.

Adhesive Installation

This is a good option if you are a business owner looking to get the longest possible warranty out of your TPO roofing. Adhesive installations usually merit longer warranty periods so that is definitely something to consider. In this method of TPO roof installation, a roofer will actually lay the rubber sheets in place first and then apply a heavy-duty adhesive to the underside of the sheets and the insulation or cover boards of the actual roof.

Seam Installation

TPO roofing can also feature welded seams to protect against leaks and moisture damage. These seams cover all of the breaks in the roofline such as vents, HVAC installations, chimneys etc.

Other Considerations

TPO roofing also performs well in conditions where traditional roofing materials tend to fail. For example, many traditional roofing materials are made out of metal and are therefore subject to rust and corrosion. TPO roofing is made out of rubber and maintains compositional integrity very well. This means that the underlayers of your roof will be better protected since rubber does not rust and corrode.

Mold is also a vital consideration when it comes to your roof. Many roofing materials (especially when  they get a lot of moisture but not a lot of direct sunlight) are susceptible to molding but again, TPO roofing is made of rubber and does not accumulate mold. Additionally, if you opt to heat weld the seams of your TPO roofing you will not have to worry about patching or repairing them any time soon. Heat welding is a superior method when compared to flashing and adhesive seaming.
