Spray Foam vs. Traditional Roofing: Which Is Better for Your Commercial Building in Wichita?

If you own a commercial building in Wichita or nearby cities like Derby, Newton, or Andover, your roof does more than just protect against rain. It helps control indoor temperatures, keeps your building safe from storms, and plays a big part in how much you spend on energy and repairs.

Choosing the right type of roof can save money, reduce problems, and help your building last longer. In this article, we’ll explain the difference between Spray Foam Roofing (SPF) and traditional roofing systems like TPO, EPDM, and Modified Bitumen. We’ll also help you decide which option could be better for your building.

At Solid Rock Commercial Roofing, we help local businesses choose strong, reliable roofs. Let’s take a closer look at these options so you can make a smart decision.

Key Takeaways

1. Spray Foam Roofing (SPF) Offers Superior Insulation
   SPF provides excellent thermal resistance, helping commercial buildings in Wichita reduce energy bills year-round.
   
2. SPF Is Seamless and Highly Leak-Resistant
   Unlike traditional systems with seams and joints, SPF forms a continuous waterproof layer, reducing leak risks during storms and freeze-thaw cycles.
   
3. SPF Installation Is Fast and Minimally Disruptive
   SPF can often be applied over existing roofs, minimizing tear-off, mess, and business downtime.
   
4. Traditional Systems May Suit Specific Needs
   TPO, EPDM, and Modified Bitumen may be better for new construction, steep roofs, or heavy rooftop traffic, depending on building conditions.
   
5. SPF Delivers Long-Term Value
   Though SPF has a higher upfront cost, it often pays off through lower energy use, fewer repairs, and extended roof life (up to 30+ years with proper maintenance).
   
6. SPF Supports Sustainable Building Practices
   With reduced waste and re-coatable surfaces, SPF is a more eco-friendly option compared to petroleum-based systems like Modified Bitumen.
   
7. Local Weather and Building Codes Favor SPF
   SPF performs well under Kansas’ extreme weather and helps meet Wichita’s energy efficiency codes.
   
8. Solid Rock Provides Honest Guidance and Expertise
   With local knowledge, certified installers, and long-term warranties, Solid Rock Commercial Roofing helps businesses make the right roofing decision.
   
9. SPF Is Often the Best Choice for Flat or Aging Roofs
   Especially for retrofits and buildings with tight renovation schedules, SPF stands out as a reliable, high-performance option.

Understanding Spray Foam Roofing (SPF)

SPF is short for Spray Polyurethane Foam. It starts as a liquid that roofers spray across your roof’s surface. As it dries, it turns into solid foam and creates one strong, continuous layer. This foam sticks tightly to the roof and fills in any cracks or gaps.

Why people choose SPF:

• It seals the roof completely—even around pipes and vents.
  
• It helps keep buildings cool in summer and warm in winter.
  
• It’s lightweight, so it doesn’t add much pressure to your structure.
  
• It can be sprayed over many types of existing roofs, so there’s less mess.
  

SPF works well for buildings with flat or low-sloped roofs, like warehouses, schools, churches, and shopping centers.

Understanding Traditional Roofing Systems

Several older roofing systems are still commonly used in commercial buildings.

TPO Roofing

TPO stands for Thermoplastic Polyolefin. It’s a single-ply white sheet that reflects sunlight and helps keep buildings cooler. The sheets are glued or fastened to the roof’s surface.

Best for: Large commercial buildings where cost and quick installation matter.

EPDM Roofing

EPDM is a rubber membrane. It comes in big black sheets that can handle sun exposure and freezing temperatures.

Best for: Industrial buildings or places with colder winters.

Modified Bitumen Roofing

This system uses asphalt mixed with other materials. It’s rolled out in layers and glued or melted onto the roof.

Best for: Roofs with heavy equipment or lots of foot traffic.

How These Roofing Options Compare

Now let’s see how SPF and traditional roofing systems match up in the areas that matter most: energy savings, leak protection, installation, lifespan, cost, and environmental impact.

1. Energy Savings and Insulation

SPF is one of the top choices for insulation. It keeps your building cooler in summer and warmer in winter. This helps you save on heating and cooling bills. Just 1.5 inches of SPF can give you strong insulation, which means your air conditioner and heater don’t have to work as hard.

TPO reflects sunlight but doesn’t insulate well unless you add extra insulation underneath. EPDM and Modified Bitumen also need added insulation layers to perform like SPF, which increases the cost.

2. Leak Protection

SPF forms one continuous surface without seams or joints. It seals tightly around vents, pipes, and other parts of your roof. This makes it hard for water to get in—even during heavy storms.

TPO, EPDM, and Modified Bitumen all come in sheets that are joined together. Over time, seams can break down and allow leaks. Wichita’s spring storms and changing temperatures make leak protection even more important.

3. Installation and Business Disruption

SPF is often sprayed directly over your current roof. That means no tearing off the old roof and less noise or mess. Most SPF jobs are finished in just a few days, even on big buildings.

Traditional roofs often need the old roof removed before the new one is installed. This takes longer, costs more, and can interrupt your daily operations.

If you run a business where staying open is important—like a clinic, store, or school—SPF may be a better choice.

4. Lifespan and Maintenance

SPF can last more than 30 years if you maintain it. Every 10–15 years, a new topcoat helps it stay strong. If there’s any damage, repairs are easy—just spray more foam in the problem area.

TPO roofs usually last 15–20 years. Their seams and corners can break down under harsh sun or strong wind. Modified Bitumen is built to take more impact but requires regular checks and patching.

5. Cost and Long-Term Value

SPF might cost a little more when installed, but it saves money over time. That’s because you spend less on energy and repairs. Many property owners see the savings add up in just a few years.

TPO is often cheaper at first but doesn’t insulate as well and may need more repairs later. Modified Bitumen costs more if you add extra layers or need special equipment for installation.

6. Environmental Impact

SPF is better for the environment than many other systems. It lowers energy use and doesn’t need to be torn off when it wears out. Instead, it’s recoated, which creates less waste.

TPO can be recycled, but it takes more energy to make. Modified Bitumen comes from petroleum and often ends up in landfills when replaced.

How Wichita Weather Affects Your Roof

Roofs in Kansas have a lot to deal with—hot summers, cold winters, strong winds, hail, and snow. SPF stands up well to all of it.

Its insulation helps during extreme temperatures, and its flexibility lets it expand and shrink without cracking. It also resists hail and stays in place during windstorms.

Kansas building codes encourage energy efficiency. SPF helps meet or exceed those rules.

Solid Rock is familiar with all local codes. We can help you avoid delays and even assist with rebates and insurance benefits tied to using high-efficiency roofing.

When SPF Is the Right Choice

SPF is often the better option if your building:

• Has a flat or low-slope roof
  
• Needs better insulation
  
• Has an older roof but a tight budget
  
• Can’t shut down for a big construction project
  

Example: A church in Derby had a 15-year-old roof. Instead of replacing it, they added SPF. The job took four days, didn’t interrupt their services, and saved money on air conditioning right away.

When a Traditional Roof May Be Better

In some situations, a traditional roof is the better fit:

• New buildings with limited upfront budgets
  
• Steep roofs where spray foam won’t stick well
  
• Roofs with heavy equipment or high foot traffic
  

Example: A shipping center in Wichita chose Modified Bitumen. They had lots of rooftop units and workers regularly walking on the roof. This system gave them the toughness they needed.
