TPO Roofing Cost Calculator

When considering replacing a TPO (thermoplastic polyolefin) roofing system, several cost-shaping factors come into play. From the material choice to labor intensity expected, each element must be carefully considered to provide an accurate estimate. We’ve asked our roofing partners to list the key factors affecting the final price of TPO roofing. Hence, you need to zero in on:

Material

TPO membranes come in various thicknesses, typically 45 to 90 mils. They can also be reinforced with polyester or fiberglass for better durability and resistance. Plus, you may want to improve energy efficiency by adding a layer of insulation material made of polyisocyanurate, expanded, or extruded polystyrene – each with different R-values and associated costs. Adding flashing to protect edges will cost you an extra penny, too.

Labor

Professional installation of thermoplastic polyolefin roofing can be charged higher or lower based on the contractor’s experience, project location, and the time of year. Roofing is labor-intensive and can eat up a fair part of your budget.

Larger housetops require more materials and person-hours to cover, linearly increasing expenses. Measurements are typically taken in squares (100 square feet) – a standard roofing unit to estimate material needs and costs.

Installation Method

The duration and project complexity are governed by the selected installation method. Mechanically attached, fully adhered, or ballasted systems have different cost implications based on material usage and time requirements.

Additional Factors

When calculating the TPO cost per square, you need to keep some extra aspects in mind. The list includes manufacturer, roof type and complexity, old roof removal and disposal, permits, inspection, repair, and customization.

TPO Roofing Cost by Material Type

Not all TPO roofing is the same, so it’s important to determine what components make a difference. It all comes down to membrane thickness, insulation, flashing, and the type of reinforcement. Let’s analyze each aspect in more depth. 

TPO Roofing Material Cost by Membrane Thickness

TPO membranes are available in various thicknesses, typically starting at 45 mils and going up to 80 mils. Thicker membranes have increased longevity, making them an excellent choice for areas prone to severe weather conditions. However, the increased thickness also leads to inflated prices. The 60 mil TPO roofing cost makes for a middle ground regarding expenditure. 

The price of a TPO housetop by membrane thickness

Thickness	The Average Cost Range (per sq. ft.)
45 mil	$1.80 - $3.20
60 mil	$2 - $3
80 mil	$2.40 - $3.50

**45 mil TPO roof membrane from $464 per roll, according to Builders Warehouse.

**60 mil TPO roof membrane from $496 per roll, according to Builders Warehouse.

**80 mil TPO roof membrane from $640 per roll, according to Best Materials.

TPO Roofing Material Cost by Insulation Type

Insulation costs start at $0.50 and can go up to $4.20 per square foot, depending on the chosen material and its properties. It equals and sometimes exceeds the cost of the TPO roofing material, so you should consider insulation when budgeting.

Polyisocyanurate (PolyISO)

When choosing this material, expect your TPO cost per square foot to increase by $1.60 - $2.40. But this investment may pay off in the future. First, PolyISO is very energy efficient thanks to its high R-value per inch, which will save you on energy bills. Second, its insulation properties are perfectly preserved due to moisture resistance, so you do not have to spend money on repairs.

Fiberboard

It is the most eco-friendly insulation option, fully made from recycled materials. When properly sealed, it is resistant to moisture and mildew. Another advantage is the affordable cost, ranging from $0.50 to $1.50 per square foot. Nevertheless, the fiberboard R-value is also lower than the alternative insulation materials.

Expanded polystyrene (EPS)

If you live in a humid climate, EPS is an excellent choice since it is very resistant to mildew, mold, and moisture. However, installing it on your TPO roof costs $3 - $4.20 per square foot. The price is higher than the market average as EPS manufacturing is more costly and labor-intensive. 

Extruded polystyrene (XPS)

Due to its strength, XPS can withstand heavy loads, which is very valuable in roof applications. Although its R-value is higher than that of fiberboard and EPS, it may still be insufficient in extremely cold climates. When selecting extruded polystyrene insulation, expect to pay roughly $1.60 to $2 per square foot. 

The TPO roofing material prices by insulation type

Insulation Material	The Average Cost Range (per sq. ft.)
Fiberboard	$0.50 - $1.50
PolyISO	$1.60 - $2.40
EPS	$3 - $4.20
XPS	$1.60 - $2

**PolyISO from $34 per panel, according to Home Depot.

**Fiberboard from $5 per panel, according to Home Depot. 

**Expanded polystyrene (EPS) from $18 per panel, according to Foam Factory.

**Extruded polystyrene (XPS) from $20 per panel, according to Home Depot.

TPO Roofing Material Cost by Reinforcement Type

When considering TPO for your roofing, you must factor in local climate and building usage to choose the appropriate reinforcement type. While both reinforced and non-reinforced types offer strong resistance to ultraviolet, ozone, and chemical exposure, they differ in quality and price. Thus, reinforced TPO includes a polyester fabric center, or scrim, layered between TPO sheets, which helps improve the durability and stability of the membrane. This reinforcement makes it more resistant to tears, punctures, and general wear. Hence, a non-reinforced alternative is suitable for less demanding situations where puncture resistance is not as critical. The absence of a reinforcement layer makes this option slightly less costly.

Flashing Cost

The cost of flashing ranges between $5 and $52 per piece, depending on whether a prefabricated or site-fabricated option is used and the complexity of the roof’s design. Your expenses can soar if your housetop is loaded with vents, chimneys, and other protrusions. Prefab flashing tends to be more expensive upfront but can offer savings in labor costs and potential future maintenance.

TPO Roofing Installation Cost

Experienced roof installers typically charge from $2.70 to $4.80 per square foot for TPO installation. These rates don’t cover any extra services, meaning adding an insulation layer or fixing leaks can raise the TPO roofing price to $7.50. Some contractors offer a flat hourly rate between $73 and $94.

Cost of a TPO Roof by Installation Method 

Installation methods differ in how the TPO membrane is attached to the roof deck. They can cost from $1.80 to $3.70 per square foot, depending mainly on the complexity of the work and the strength of the attachment.

Ballasted Attachment Method

In this method, the ballast, often pavers or gravel, covers the top of the TPO membrane and holds it in place, minimizing the need for additional adhesives or fasteners. Also, spreading the ballast over the surface is not difficult, so this work is not laborious for the roofer and does not take much time. Therefore, this method will cost you between $1.80 and $2.50 per square foot. 

Fastened Attachment Method

As the name suggests, fasteners attach the TPO membrane to the substrate or deck. In this case, you pay $2 - $3 per square foot. This method is less time-consuming than others. In addition, it allows you to easily repair or replace a roof section in case of damage. However, fasteners tend to fail over time, which can lead to leaks.

Fully-Adhered Attachment Method

On average, this method of TPO installation costs $2.75 - $3.50 per square foot. It may be the best solution if strong winds are common in your area. Using it, the contractor attaches the membrane to the roof deck with a special adhesive. This strong bond securely protects your roof from wind uplift. 

The price of a TPO housetop by installation method

Installation method	Average cost per sq. ft.
Ballasted	$1.80 - $3
Fastened	$2 - $3.50
Fully-adhered	$3 - $3.70

Our Conclusion

What is a TPO roof popular for? As our partners have reported, a striking feature of TPO rooftops is their ability to reflect UV rays. Hence, homeowners can significantly reduce HVAC costs and energy consumption. This roofing material also boasts excellent resistance to ozone, chemical exposure, and algae growth, which prolongs the roof’s lifespan and reduces maintenance needs.

Installation of a TPO housetop is generally straightforward but requires precision. It involves rolling out the TPO membrane across the roof deck and securing it either with mechanical fasteners or fully adhering it with adhesive. Seams are then heat-welded to create a watertight barrier. Our partners emphasize the importance of proper seam welding to prevent leaks.

DIY vs. Hiring a Pro to Install TPO Roofing

DIY installation can appear cost-effective initially but requires a significant time commitment and technical knowledge. You need to know the ropes of roofing techniques, access specialized tools, and devote time to extensive preparation to ensure proper seam welding and material handling. Mistakes can lead to leaks, reducing the housetop’s lifespan and efficiency and potentially negating initial savings with future repair costs.

Conversely, hiring a professional guarantees expertise and experience, ensuring the TPO roof is installed correctly. Professionals handle permits and inspections and follow building codes, providing peace of mind and warranty advantages. 

What Are the Pros and Cons of TPO Roofing?

When discussing the advantages of a TPO housetop, it is necessary to highlight its energy efficiency thanks to its reflective capabilities. TPO is also resistant to dirt accumulation, tears, and punctures. Its flexibility allows it to handle building movements and settlements without compromising integrity. Compared to other roofing materials like PVC and EPDM, TPO offers a cost-effective solution with similar features. Moreover, TPO membranes are eco-friendly, as they are usually 100% recyclable and comply with green building standards.

However, you need to be careful when selecting roofing materials. As TPO is relatively new, the market shows variation in quality across different manufacturers. Poor workmanship can also lead to issues like seam failures and membrane tearing.

How Does TPO Compare to EPDM in Terms of Performance and Durability?

TPO generally offers a stronger resistance to punctures than EPDM and tends to have better seam strength due to its hot-air weldable seams. On the other hand, EPDM, a synthetic rubber, boasts excellent resistance to UV rays, ozone, and weathering, making it highly durable, with a lifespan often exceeding 20 years. It is also more flexible in low temperatures than TPO, which makes it suitable for colder climates. However, EPDM’s traditional black color absorbs rather than reflects heat, potentially increasing air conditioning costs unless coated with a reflective material. Hence, if you can’t decide between TPO and EPDM, analyze your environmental conditions and energy efficiency needs.
