2021 TPO Roof Cost and Pros & Cons of TPO Membrane Roofs

Say it with me: Thermoplastic polyolefin. Yes, TPO is much easier. According to Firestone Building Products’ white paper, TPO is technically a polypropylene based plastic combined with ethylene/propylene rubber.

So, plastic and rubber, mixed is what comprises a thermoplastic roofing membrane designed primarily for low-slope roofing applications with energy-efficiency in mind.

Much of the information online boasts how TPO is increasingly popular in commercial flat roofing. The thing is, we aren’t concerned with commercial buildings, and instead focus on the membrane options available, along with the costs, for adding this material to a residential roof.

Cost and Value

The main thing with effectively estimating the price to install a TPO roof is finding a qualified professional who can do the job. Mechanically attaching the material, or even gluing (fully adhering the membrane to the roof deck), is something most roofers can probably do.

Effectively hot air-welding the membrane seams takes special care, skills, tools, and experience. If the hot air welding of the membranes’ seams is not done properly, then the entire TPO roof system could be compromised at the seams, and hence be subject to costly roof leaks.

In our research, RoofingCalc.com lists residential TPO roofing costs at $6.50 to $12.50 per sq. ft. for materials and professional installation, however some residential and commercial contractors will install it for as low as $5.50 to $7.50 per sq. ft., but only on larger straightforward projects or very simple and easily accessible residential projects that can be completed in a day or two.

Synthetic Shake and Shingle Pricing Guide for 2021

Synthetic shake and shingles are polymer-based material, or a combination of plastic and rubber. They are used on roofs where homeowners desire the classic look of wood or natural slate, with the added benefits from the synthetic blends.

Synthetic shingle roofs are relatively new to the residential roofing market, first arriving in the early 1990s. Their durability, environmental friendliness and affordability have all contributed to their rising success.

Cost

For a 2,000 square foot roof on a typical, single-family house (up to two stories high), it will cost between $8.50 and $12.50 per sq.ft. installed. This results in an average total price range of $17,000 to $25,000. If the existing roof needs to be torn off and disposed of first, this can sometimes cost an additional $2,000 to $3,500 more.

The location of your home can greatly influence the overall cost of a new roof. Expect to pay more for a new roof on a house in an expensive coastal city relative to the cost of new roof in rural areas in the South or Midwest.

A more complex roof with multiple cut-up angles, dormers, peaks and valleys, or steeper pitch than average would add to the complexity of the project, and hence cost more as a result.

Metal roofs are becoming increasingly popular with many savvy homeowners and it’s not hard to see why; compared to the more traditional approaches like asphalt shingles and cedar shingles and shakes, metal offers many important advantages including a significantly longer lifespan, low maintenance, excellent durability, and superior energy efficiency.

Cost:

On average, you can expect to pay between $8.50 to $15.50 per square foot to install a metal roofing system on a typical residential house. For example, an average-sized single-story house with a fairly simple roof shape measuring about 2,000 sq. ft. or 20 squares could cost anywhere from $17,000 to $31,000 for the installation of a high-end metal roofing system such as stamped metal shingles or tiles and standing seam metal roofs.
