Introduction
If you own a commercial building in Kansas—maybe in Wichita, Derby, or Newton—you know that commercial roof repairs or replacements are big decisions. You might get two quotes for the same job and see something surprising: one contractor bids $70,000, and another bids $100,000. That’s a big gap.
It’s natural to wonder: is the higher bid overpriced? Or is the lower bid missing something important?
At Solid Rock Commercial Roofing, we’ve seen this often. A cheaper price can be tempting, but roofing isn’t just about numbers. What’s included in each bid—and how the work will be done—makes all the difference. This article breaks down why roofing bids can differ so much and how to choose the right one.
Key Takeaways
- Not All Bids Are Equal: A lower roofing bid may not include the same scope of work, materials, or warranty coverage as a higher bid. Always compare the details, not just the price.
- Low Bids Often Skip Critical Steps: Contractors may cut costs by omitting tear-offs, repairs, insulation, or cleanup. These shortcuts can lead to leaks, poor energy efficiency, or early roof failure.
- Material Quality Varies Widely: Two bids that mention the same roofing system (e.g., TPO) may use vastly different brands, thicknesses, and components, affecting performance and lifespan.
- Labor Matters: Skilled, experienced crews ensure a reliable installation. Cheaper bids often come from contractors using untrained or unsupervised labor, increasing the risk of mistakes.
- Permits and Insurance Should Be Included: Some contractors skip permit fees or proper insurance to lower costs, which can expose property owners to legal and financial risks.
- Warranties Are Not All the Same: Contractor-only warranties are often weak and may disappear if the contractor closes. Manufacturer-backed warranties offer stronger, longer-term protection.
- Local Roofing Companies Offer More Accountability: Out-of-town roofers may offer lower prices after storms but disappear quickly. Local companies like Solid Rock offer ongoing service and support.
- Value Over Price: A higher bid that includes complete work, better materials, strong warranties, and reliable follow-up often delivers far more value over the long term than a low-cost bid.
- Transparency Builds Trust: Solid Rock Commercial Roofing provides clear, detailed bids so building owners understand exactly what they’re paying for and why it matters.
Low Bids Can Lead to Big Problems
A low bid might seem like a win at first. But it often skips steps or uses cheaper materials to cut costs.
Some contractors don’t include tearing off the old roof or fixing water-damaged areas. Others skip insulation or use off-brand materials. Labor might come from temporary or untrained crews. The work may look fine now, but problems can appear later—like leaks, high energy bills, or early system failure.
At Solid Rock, we don’t take shortcuts. We price jobs to include what’s needed to do it right—the first time.
Not All Bids Cover the Same Work
The “scope of work” tells you what’s actually included in your roofing bid, and it’s often where the biggest differences show up.
One contractor might include:
- Removing the old roof
- Fixing damaged decking
- Installing new insulation
- Replacing flashings
- Full cleanup
Another might simply cover:
- Laying a new layer over the existing roof
- Minor repairs only
These are not equal jobs—even if the materials sound similar. Skipping key steps might lower the cost now, but it increases risks and shortens the roof’s lifespan.
At Solid Rock, we clearly list every part of the job so you know exactly what you’re getting.

Materials May Look the Same but Perform Differently
You might see “TPO roofing” on two bids and assume both use the same product. But one may use a 60-mil high-quality membrane, and the other a thin, 45-mil off-brand version. That affects durability, warranty, and performance.
The same applies to other materials:
- Fasteners and adhesives
- Insulation quality
- Flashings and edge metals
Lower-cost materials may look okay at first, but they often wear out sooner or don’t qualify for strong warranties.
At Solid Rock, we use certified materials from trusted manufacturers. We prioritize long-term performance over short-term savings.

Labor Makes a Big Difference
Good roofing systems rely on skilled installation. Some companies save money by hiring low-cost, less-experienced workers who rush through jobs.
These shortcuts can cause:
- Loose seams
- Poor drainage
- Weak flashing
- Early leaks or wind damage
Solid Rock uses experienced crews who follow best practices. Every job has oversight to ensure quality work from start to finish.
Permits and Insurance Are Often Overlooked
Some contractors lower their bids by skipping permit fees or lacking proper insurance.
That can leave you exposed. If a worker is injured and their company isn’t insured, you could be held liable. If permits aren’t pulled, you might face penalties later.
We handle all permits and carry full insurance. With Solid Rock, your project is done safely and legally.
Warranties Vary Widely
A “warranty” may sound good, but it’s important to understand what it covers.
Some bids offer short, labor-only warranties. Others don’t register systems with the manufacturer, so you lose coverage without knowing it.
Solid Rock provides:
- Long-term warranties
- Labor and material coverage
- Proper registration
- Support for future service needs
We stand by our work and remain available for support—years after the job is done.
Local Contractors Offer Real Support
After big storms, out-of-town roofers often flood Kansas with fast, low bids. They complete quick jobs and leave. If problems come up later, they’re long gone.
Solid Rock is based right here in Kansas. We know local codes, weather conditions, and suppliers. And we’ll be here when you need us again.

Frequently Asked Questions (FAQs)
Why do roofing bids vary so much between contractors?
Roofing bids can vary by 30–40% because contractors may offer different scopes of work, materials, labor quality, warranties, and compliance with permits and insurance. One bid might include a full tear-off and insulation, while another might only cover a surface overlay.
Does a higher price always mean better quality?
Not always—but in many cases, a higher bid reflects a more complete, durable solution with better materials and experienced labor. It’s important to compare not just the price but what is actually included in each bid.
What should I look for in a roofing bid?
Look for a clear scope of work, brand and thickness of materials, warranty coverage, labor details, cleanup responsibilities, permit handling, and insurance confirmation. A well-documented bid helps you avoid hidden costs and surprises.
Can a cheaper roofing bid end up costing more later?
Yes. A low bid might save money upfront but can lead to expensive problems down the road, such as leaks, energy loss, warranty voids, or even full roof failure. Incomplete jobs often lead to additional repair costs.
Why is insulation often left out of lower bids?
Insulation is a critical but costly component of commercial roofing. Some contractors leave it out to lower their bid price, which can reduce energy efficiency and lead to code violations or higher heating/cooling costs.
What kind of warranty should I expect with a quality roofing system?
A quality roofing system should come with a long-term, manufacturer-backed warranty—ideally 15 to 20 years—covering both labor and materials. Contractor-only warranties may not provide lasting protection.
How do I know if a contractor is using quality materials?
Ask for specific product names, thicknesses, and manufacturers. Verify if the roofing system qualifies for a manufacturer warranty. Solid Rock uses only certified, high-performance materials backed by industry-recognized manufacturers.
Are out-of-town roofers a bad idea?
Not always—but many out-of-town contractors chase storms and may not stick around for warranty claims or repairs. Working with a local, trusted company like Solid Rock ensures accountability and ongoing service.
What risks do I face if a contractor doesn’t pull permits or carry insurance?
Without proper permits, your project may not meet code, which can result in fines or forced rework. If a contractor isn’t insured and a worker is injured on your property, you could be held liable for damages.
