Professional TPO Roofing Services in St. Louis, Missouri
Your property deserves more than just any flat roofing system overhead. Whether you’re protecting a commercial building, industrial facility, or residential property with a low-slope roof, the quality of that TPO installation determines everything. How long your roof lasts. How well it protects your inventory and equipment. How much you spend on cooling costs during brutal St. Louis summers. How your building performs under extreme weather. One professional TPO installation done right protects your investment for decades. One careless installation creates problems you’ll fight for years.
When you’re ready to install a new TPO roofing system, you face dozens of decisions that seem overwhelming. Which membrane thickness actually performs well in Missouri’s climate? How critical is proper seam welding? What insulation provides real energy savings? Should you upgrade to a reinforced membrane? Do you need additional drainage systems, and if so, where? These aren’t just technical details. They’re the difference between a TPO roof that performs beautifully for 25 years and one that fails in year seven.

Why St. Louis Property Owners Need Reliable TPO Roofing
Here’s what separates professional TPO roofing from amateur work. The membrane materials themselves are only half the equation. How those materials get installed matters just as much as which manufacturer you choose. We’ve torn off countless flat roofing systems that used premium TPO membranes but failed early because someone rushed the installation, skipped critical seam welding steps, or didn’t understand proper flashing techniques around penetrations.
St. Louis’s weather demands more from your TPO roof than most people realize. Spring thunderstorms test every seam’s integrity against driving rain. Summer heat cycles above 100 degrees challenge membrane stability thousands of times. Fall windstorms stress every perimeter attachment point. Winter freeze-thaw cycles push water into any gap where poor installation leaves vulnerabilities. Your TPO roof installation needs to handle all of this, year after year, without compromise.
The Hidden Cost of Poor TPO Installation
Picture this common scenario. You hired the lowest bidder to install your new TPO roof last year. Everything looked fine when they finished. But now you’re noticing problems. Seams separating near your HVAC units during temperature swings. Ponding water accumulating where drainage wasn’t properly sloped. Membrane shrinkage pulling away from parapet walls where flashing wasn’t adequately sealed. Your expensive new roof is failing, and the company that installed it stopped returning your calls months ago.
Poor installation doesn’t announce itself with obvious signs on day one. It reveals itself slowly through premature seam failures, costly roof leak repairs, and endless frustration. By the time you realize something’s wrong, your warranty claims get denied because “improper installation voids coverage.” You’re stuck paying twice for the same roof.
This happens across St. Louis, Clayton, Chesterfield, and Kirkwood every single month. But it absolutely doesn’t have to happen to you.

How much does TPO roofing cost in St. Louis?
Most St. Louis TPO roofing installations range from $6 to $12 per square foot, depending on your building’s size, accessibility, and membrane thickness. A typical 10,000 square foot commercial roof averages $60,000-$90,000 fully installed. Smaller residential flat roofs typically cost $8,000-$15,000 depending on complexity. We provide detailed written estimates after your free consultation, and you pay nothing until installation is 100% complete.
How long does TPO roofing installation take in St. Louis?
Most commercial TPO roofing installations take 3-7 days with our experienced crews. Simple residential flat roofs can often be completed in 1-2 days, while complex commercial buildings with multiple penetrations typically take 5-7 days. New construction timelines coordinate with your general contractor’s schedule. Weather conditions can affect the timeline, as TPO welding requires specific temperature ranges.
What membrane thickness do you recommend for St. Louis buildings?
For most St. Louis commercial applications, we recommend 60-mil or 80-mil TPO membranes for optimal durability and puncture resistance. The 60-mil membrane works well for standard commercial buildings, while 80-mil provides extra protection for high-traffic roofs or buildings in hail-prone areas. During your consultation, we show you membrane samples and explain which thickness works best for your specific building and budget.
Do you handle TPO roofing for new construction projects?
Yes, we work with property owners, developers, and general contractors on new construction TPO roofing throughout St. Louis. We coordinate with your construction timeline, deliver materials on schedule, and install your TPO system according to code requirements and manufacturer specifications.
Can TPO roofing be installed over my existing flat roof?
Building code allows recover installations in some situations, but we evaluate each roof individually. Complete tear-off and reinstallation lets us inspect your deck, replace damaged insulation, ensure proper drainage, and install new vapor barriers. This approach delivers better long-term performance and allows full manufacturer warranties. If your existing roof has moisture issues, we always recommend roof replacement rather than recover.
What makes Coldstream Exteriors different from other St. Louis roofing companies?
You pay nothing until your TPO roofing installation is 100% complete and you’re satisfied. No deposit, no progress payments, no financial risk. We’ve earned our BBB A+ rating and 4.9 stars from 400+ customers by treating St. Louis property owners right for over 25 years.
How do I prepare my building for TPO installation?
We handle most preparation, but property owners should ensure roof access is clear, move vehicles away from the building perimeter, cover sensitive equipment below work areas if accessible from inside, and notify tenants of installation dates. We’ll provide a complete preparation checklist before we start.
