If you have a building with a flat roof, or nearly flat, then you’ve likely already realized that there are a several options out there to help insure your roof is protected for in the long-term. The two most commonly used materials are EPDM membrane and TPO. If you want to get help in deciding, a roofer is the best person to point you in the right direction to make the decisions. Then there is the question of a new roof or re-coating. Re-coatings is significantly less expensive.
People use to prefer TPO due to these reasons:
· Puncture Resistance
· Dimensional Stability
· Energy Efficiency
· Installation Convenience
· Seam Strength
Roofs are based on a variety of factors; all of which go into what kind of a roof to install.
Come at the Cost Comparison:
EPDM roofing has low cost and it is cost effective in three ways. First purchase price is less. Second, since you are applying it yourself in many instances it saves you the cost of hiring a roofer to do the work. The third one is its performance history is second to none; a long-lasting durable solution with very low maintenance. Low cost is the element, something that most property owners are keeping as their priorities; EPDM roofing is the most economical choice. In Durability Comparison: EPDM Roofing is superior to TPO.
In performance tenure lasting TPO is new compared to EPDM roofing. EPDM roofing can last for multiple decades, without changing its outer and inner condition performing in all-weather climate. It can withstand all the common environmental factors that cause roofing materials to become brittle and crack over time such as low and high temperatures (up to 300 F) but even more impressive are the significant temperature swings EPDM can tolerate due to its overall elongation.
Now again EPDM installation is as easy since it is a DIY process for most applications. It requires a squeegee and med nap roller. As a business owner or homeowner epdm provides more benefits to protect your building. As a quality rubber roof coating that is fast and inexpensive.
TPO offers greater puncture resistance up to three times the puncture resistance of non-reinforced EPDM of the same thickness. EPDM repair gives your roof heat and cold resistance.
EPDM Vs TPO in the field of giving energy efficiency. TPO is also good but EPDM reduces more than 40% of your bills. EPDM gives you the guarantee of decades.
EPDM has better dimensional stability. The amount of savings will vary depending on the area of the country you are in; climate zone, utility rates etc. The possible difference can be found in insulation levels, HVAC equipment efficiency, and other factors.
Liquid EPDM Application:
While a beginner roofing contractor will most likely be able to properly install an EPDM membrane, you should only hire an experienced contractor to install an a TPO roof. While EPDM roofing membranes are also available in white and will offer better reflective properties than darker colored EPDM, a TPO roof will not offer the same level of energy and financial savings as an EPDM roof. EPDM provides strength to the surface and seams. It never leaves an opportunity for next leak to occur. A epdm roof has been know to last 20–25 years before any additional work needs to be done.
