TPO Advantages
The most impactful advantage of TPO roofing is its inexpensive cost. In most cases, you can expect to pay between $3.50 and $9.50 per square foot. Overall, TPO roofing costs typically range between $7,000 and $11,500.
TPO holds up well to long-term exposure to the sun’s ultraviolet light. TPO is highly resistant to puncturing, tearing, or water damage.
Mold growth, punctures, tears and the accumulation of dirt are practically non-existent making is easy to maintain your roof.
TPO membranes will effectively reflect the sun’s heat. TPO membranes are also made entirely from recyclable materials, having a much lower environmental impact than other roofing materials.
TPO Disadvantages
Being so new on the market, TPO roofs have not undergone the test of time. Product research is still conducted today to develop long-lasting, durable TPO roofs that are also cost effective.
The uppermost part of a TPO roof is laminated. The sheer presence of lamination on any material introduces weak points, spurring shrinkage, cracking, and general deterioration over the course of time.
TPO roofing membranes are sold in small-width rolls, meaning seams are present in every six to eight feet. Contractions and expansions occur in the membranes, and the seams are often areas where the membranes become loosened, leading to water leaks in your roof.
Different manufacturers produce different qualities of TPO roofing membranes. One roofing manufacturer may produce a great product, while for the same price, another manufacturer will construct a far lower quality product.
