Do You Need A New Roof?
Are you a business owner, who has a flat roof? Then you most likely already have a single-ply membrane roofing system or considering one for the future. There are two types of roof materials to choose from TPO and EPDM.
TPO (Thermoplastic polyolefin)
TPO stands for thermoplastic polyolefin. It’s a single-ply roofing membrane that is one of the fastest-growing commercial roofing systems on the market. TPO roofing systems are made up of a single layer of synthetics that can be used to cover flat roofs.
Modified Bitumen Torch Down
Torch down roofing is named because it requires an open-flame propane torch. In this installation method, sheets of modified bitumen are rolled out onto the roof, and a roofing professional uses a hand-held propane torch to heat the material and adhere it to the surface.

TPO Roofing Cost Factors
All TPO roofing projects are unique to the plenty of considerations that can increase or decrease the overall price. A TPO roof system is primarily used on flat roofs, it is vital to hire a professional TPO roofing contractor to install the roof system to ensure all goes well during heat welding and a successful roofing installation.
How does a roofing company price a TPO roof? Here are the 4 factors that affect the price of a TPO roof:
1. Number of Layers on Your Roof
At HHH Roofing, within our 30 years we have seen many commercial projects from only having 1 layer to multiple layers on their flat roofs. We will take a sample of your roof, to completely identify how many layers we are working with. This will determine how many layers we will remove and determine the length of screw we will use to install your new roof system.
The more layers we remove will increase the total price.
The longer the length of the screw will also increase the total price.
2. Type of Current Roof Decking
Flat roofs have 2 different types of roof decking: Metal and Concrete. If you have concrete decking, a TPO install will require special nails and take longer to complete the job.
3. Extra details and AC Units
With commercial properties that have lots of AC units will require more labor. The more equipment the roofers will have to move will slow down the install of a TPO membrane versus if the roof was clear, thus increasing the overall cost.
A TPO roofing contractor will also take into account how tall the walls are on your roof, thus requiring more square footage of TPO membrane.
4. Insulation Choice
After the existing substrate is prepared the insulation is installed.
There a few types of insulation options to choose from:
Polyiso is the most commonly used insulation for roofing. It’s a rigid material that can be cut to size for installation. The R-Value is the highest per inch of commercially available insulation products.
Below are the costs for 3 different thicknesses:
- 1 inch – $1.40 – $1.75 per sq. foot in materials and labor
- 2 inch – $2.00 – $2.50 per sq. foot in materials and labor
- 3 inch – $2.80 – $3.15 per sq. foot in materials and labor
When it comes to insulation it comes in all sorts of sizes. For example we have fan fold insulation that is about 1/2″. We can also use ISO insulation that come in 1″, 2″, 3″, etc.
The insulation you go with will depend on the roof you have on right now and how much insulation you already have. For example: if you have a gravel roof we can’t use fan fold insulation. But if you already have a TPO roof we can install fan fold insulation and then a new TPO Roof on top of that.
5. TPO Thickness & Adhesive
Usually, thicker TPO roofs will cost more. When it comes to TPO we can get it in different options. How your roofer connects the TPO to your roof matters. We can not only change the Mil (60Mil, 80Mil, etc), but we can also attach it mechanically or self-adhere.
- Manufacturer Warranty: Most brands have a basic warranty with the product, you can choose to upgrade but usually it will cost more.
- Company Warranty: This warranty varies from company to company. A company will at times offer there own warranty on the labor giving you the piece of mind everything was installed correctly.
