What is TPO Roofing? Let River Run Roofing Supply Affordable TPO

Feb 9, 2021Blog, Commercial Roofing, TPO

If you own a building with a flat roof, you’ve likely heard about TPO or single-membrane roof systems.


TPO stands for thermoplastic polyolefin and it’s a single-ply membrane installed on commercial roofs to provide leak protection as well as heat-reflective benefits.


Demand for TPO roofing is on the rise as cities strive to combat urban heat island effect through cool roof options such as TPO.



TPO roofing is among roof systems considered as “green” options because of their reflective properties. For low-slope and flat roofs, this Energy Star-rated commercial roof option can provide energy efficiency to your building at an affordable price.


Additionally, the reflective surface is both recyclable and composed of recycled content. White roofing can have an initial solar reflective of 80% or higher to reduce your building’s energy bills.  White roofs can reduce temperatures in city buildings especially. The darker the roof surface, the more it emits heat. Cool roof systems such as TPO roofing may help with regional-scale climate adaptation and mitigation (see this Nature GeoScience article for more details).


TPO roofing is less expensive to install than other rolled rubber roofing and EPDM. However, it must be properly adhered to the roof substrate to avoid moisture below the membrane. Loosely installed TPO will leave your building susceptible to moisture, mildew, and even leaks.


River Run Roofing is one of the top TPO roof installers in the mid-Atlantic region. First, we’ll clean off the surface of your roof to remove debris or buildup. We then mechanically fasten your TPO roofing to make sure it’s securely attached to the roof substrate. We then seal around flashing, the roof perimeter, and around any penetrations.


The cost of TPO roofing will vary, but it will average between $5-$8 per square foot not including labor. The condition of your decking system, roof layout, number of penetrations, and other factors will play a role in determining how much your TPO roofing will cost.


River Run Roofing can help finance up to $100,000 toward your commercial roofing project through our partnership with Enhancify. Learn more about roof financing.


A TPO roof system can add 20-30 years to your commercial roof. Conklin’s optional warranty program includes a non-pro-rated material warranty for 18 years. A non-prorated warranty means that your coverage won’t decrease over time. If any issues occur, you’re 100% covered over the duration of that time.


Your TPO roofing doesn’t need annual inspections. Through River Run Roofing’s maintenance program, you can extend the labor warranty up to the material warranty. We can use our camera app to inspect your TPO roofing to spot potential weak spots before they become larger problems. Our professionals can spot leaks, buckling, cracking, and other commercial roof issues and provide affordable roof repairs.

9 Questions To Ask Potential Roofing Contractors 

Hiring a contractor can be overwhelming. There are hundreds of roofing contractors in  Eastern PA alone. How are you supposed to choose one? 

We can’t decide for you, but the following 9 questions will help you pick a competent contractor and avoid ending up with a bad one. 

  • Are you licensed and insured? 

It’s essential to ask about insurance for several reasons. For one thing, when a contractor has all their papers in order, it shows they care enough to follow proper procedures. 

And secondly, having proper paperwork protects both you and your roofer should anything go awry. 

The requirements to become a licensed roofer differ from state to state. In PA, contractors must meet the Home Improvement Consumer Protection Act requirements and register at the Pennsylvania Attorney General’s Office. 

Regarding insurance, PA law requires roofing companies to provide their employees with worker’s compensation insurance. Worker’s compensation protects you, as the homeowner, from being financially responsible for any injuries that might occur on your property. 

Your contractor should also have general liability insurance. This protects you from being responsible for any damage or injury to non-employees that might occur on your property, such as a bystander being injured on property damage.

  • Are you local? 

Some roofing companies like to move from town to town following storm damage. These companies may not be familiar with local laws and regulations, and if there is a problem with your roof after installation, they wouldn’t be available to help you. 

We aren’t saying this is a bad or dishonest business model. Just keep in mind that these companies won’t be around long-term.  

Hiring a local company is normally better, so ensure your contractor has a local address and phone number. Then if complications arise, they’ll be around to assess the situation. 

  • How long have you been in business? 

The longer a contractor has been in business, the better they understand their trade. And while it’s not wrong to hire a new company, it’s more risky. A roofing company that has “been around the block” understands all the ins and outs of a roofing system and will likely do a better job. 

Plus, the longer a business has been around, the more likely they are to be in business for years to come, and that means they’ll be around if you need them in the future. 

  • Do you offer a warranty on your products? 

Roofers may offer warranties for 1, 5, 10, or 25 years or even for life. Normally the roofing company’s warranty covers the work, and the materials manufacturer offers another warranty for the materials, so there are two separate warranties. 

Roof warranties typically last a year, and an extended warranty may add to the overall cost of your project.

  • Do you use subcontractors? 

Some companies use subcontractors to help them get the work done. You should know if your contractor uses subcontractors for several reasons. 

  • One, you don’t want to be completely surprised and confused when trucks with an unknown company name on them show up at your place and strangers start working on your roof.
  • Two, you should ensure that all subcontractors have adequate licensing and insurance. 
  • And three, sometimes disreputable contractors neglect to pay their subcontractors, and in such a case, you could be held financially responsible. You may want to consider getting a lien waiver for the project to protect yourself from this. 
  • Do I need a full roof replacement or just repairs? 

You don’t want to fork out the money to replace your entire roof if you could fix your issues with some simple repairs. Alternatively, you don’t want to put a bandaid on a broken leg by replacing a few shingles when the problems go deeper. 

Knowing the extent of your roofing damage will allow you to make the best possible decision for your home.

  • Will you remove the old roof?

When fixing a roof, there are two options: tear off the old roof and completely replace it or install new roofing materials over the old roof. 

Roofing over old materials is faster and cheaper since you save the time and labor to tear the old roof off. However, if you go for this option, you won’t see your roofing system’s actual state as clearly. If there are underlying issues you missed, you may need to replace the roof a few years down the road anyway. In that case, the money you spent on roofing overtop would be wasted. 

An expert contractor can help you make a wise decision about repairing or replacing your roof. 

  • Do you have a cleanup policy once the installation is complete? 

Installing a roof is a messy project that leaves a lot of scraps and debris. You don’t want to be left in the lurch with a huge mess in your yard. 

Ask your contractor what their cleanup policy is before you hire them–a quality contractor will have policies in place. 

Will there be a dumpster sitting in your yard? Or do they hire a trash removal service? Some trash removal methods may have implications for your property and yard, and it’s best to ask about them so you aren’t surprised. 

  • How will you protect my property and yard during construction? 

During a construction project, there may be scraps lying around, large vehicles driving through your yard, and strange people in your home. Your contractor should have policies to protect your property, so it’s left mostly the same as before.  

Some companies enforce mandatory foot traffic patterns so your flower beds and grass don’t get trampled. Some use large magnets to pick up any nails that might have fallen in your yard so your children and pets don’t get injured. 

You should make sure your contractor is conscientious enough to treat your property like their own.  

Tips For Hiring A Competent Contractor 

Those are a few questions you should ask your roofing contractor before signing anything. As a bonus, here are a few miscellaneous tips for hiring a good roofing contractor: 

  • Ask for some references or previous jobs you could look at. Talking with previous customers and asking about their experience with a contractor is one of the best ways to learn more about them. 
  • Request roofing price estimates from several contractors in the area and compare them. That gives you a good idea of a reasonable price. 
  • Know your needs. Do you need to complete the project by a specific time at all costs? Or do you have a specialized roofing system requiring unique expertise? If so, these things affect what contractor you should hire. 

There are lots of good contractors out there! These questions and tips should help you make a good decision for your home.
