What You Should Know About TPO Roofing
Thermoplastic polyolefin or TPO is a durable roofing material made from ethylene-propylene and a variety of fillers. These materials include carbon fibers, talc, and fiberglass. The material is then rolled out into a three-layer system. The base layer is made of the same material as the top layer.
When considering TPO roofing, you need to consider the cost of installation. The average cost is $2 to $4 per square foot, but the price can be as high as $11 per square foot for steep-sloped roofs. Additionally, you will need flashing, which will keep water from getting underneath the roofing. These materials add about 5% to the overall cost of TPO roofing.
The thickness of the TPO roofing membrane varies from 45 to 60 inches. A thicker TPO roofing material offers more protection against UV rays, puncture resistance, and durability. The material is available in several colors, but will cost more if you want it in a color other than white. Common colors that are available without an additional fee are white, tan, and grey. TPO roofing installation is a specialty flat roofing material, and you may need a trained roofer to complete the job properly.
TPO roofing membranes offer performance and durability that exceed expectations. The industry reports that many TPO roofs are over 20 years old and are still performing well. In 2009, TPO roofing accounted for approximately 25 percent of the commercial roofing market. Wacenke of Firestone discussed the ASTM standard for TPO roofing as well as the durability tests performed.
Although TPO roofing membranes are popular and easy to install, they have one major drawback: premature degradation. Temecula Roofer Exposure to heat and UV rays can cause premature degradation of the polymer, which leads to small cracks and a loss of tensile strength and elongation. To counteract this problem, TPO membranes are treated with UV light stabilizers. The light stabilizers help to prolong the lifespan of the roof.
TPO roofing is one of the more energy-efficient types of flat roofs. It reduces the cost of cooling your home during warm seasons and can help you cut your carbon footprint. However, TPO roofing requires extensive installation. To get the best results, you should seek the services of a professional contractor.
TPO is a relatively new roofing material and manufactures are still tweaking the formula to make it more durable. This means that if your roof gets damaged, the formula for the repair may be different than the one used during the initial installation. There have been some recalls and problems with TPO roofing in the past, but they have been resolved with new formulas. The most common problems include seams coming apart, membrane failure, and leaks. These problems are typically the result of improper installation or exposure to extreme heat.
To maximize the lifespan of your TPO roofing, preventative maintenance is essential. It helps keep the membrane clean, which helps the roof reflect sunlight, and reduces the likelihood of mildew and mold growth. It also helps minimize damage from chemical contaminants. To clean your roof, use a low-pressure power washer and a soft-bristled brush. Ensure that you follow GAF guidelines for cleaning and repair.
Preventative maintenance for TPO roofing also means knowing how to repair it if necessary. To repair your TPO roofing without ruining the warranty, you must contact the manufacturer before you start any repairs. Otherwise, you could void the warranty and be stuck paying out of pocket. In addition, it is best to limit the scope of repairs to relatively simple tasks.
