Choosing the Right Flat Roof Can Save You Thousands
Flat roofs can be a smart design choice—but only if they're built to handle Utah's extremes. From blazing summer UV rays to heavy snow loads in winter, the wrong roofing material can mean constant repairs, heat loss, and money down the drain.
If you're a homeowner or property manager in Salt Lake City, and you're wondering which flat roof material will last the longest, perform the best, and offer real value—you’re in the right place.
In this guide, we’ll break down exactly what you need to know to make the right decision.
What We’ll Cover
Flat Roof Materials Explained
There’s no one-size-fits-all solution. Let’s break down the most common materials for flat roofs:
- Durable, reflective, and energy efficient
- Welded seams make it resistant to leaks
- Common in commercial buildings
EPDM (Ethylene Propylene Diene Monomer)
- Rubber-based and flexible
- Excellent for extreme weather tolerance
- May absorb more heat (black surface)
- Asphalt-based with reinforced fabric layers
- Affordable and easy to install
- Prone to cracking in cold unless maintained
- Multiple layers of tar, asphalt, and gravel
- Time-tested but heavy and labor-intensive
Which Material Performs Best in Utah?
With our freeze-thaw cycles, summer sun, and snow accumulation, these materials tend to perform best in Salt Lake County:
Top Performers for Utah Climate
- TPO Roofing: Excellent UV resistance and low heat absorption
- EPDM Roofing: Ideal for durability across temperature swings
Best Overall? For most homes and light commercial properties in Utah, TPO is a leading choice. It balances cost, energy efficiency, and longevity.
Cost Comparison by Material Type
Here’s what you can expect to budget (per square foot installed):
| Material | Avg Cost (Installed) | Lifespan |
| TPO | $5.50 – $7.50 | 20–30 years |
| EPDM | $4.50 – $6.50 | 20–25 years |
| Modified Bitumen | $4.00 – $6.00 | 15–20 years |
| Built-Up (BUR) | $5.00 – $7.00 | 15–25 years |
Pro Tip: The real cost comes not just from materials but installation quality. That’s why warranties and local contractor expertise matter more than most people realize.

When to Replace vs. Repair
Not sure if it’s time for a new flat roof? Here’s how to tell:
Replace your flat roof if:
- You see consistent ponding water
- Repairs are costing you more than 25% of replacement
- There's widespread cracking or seam failure
Repair your roof if:
- Issues are isolated (like a small puncture)
- The membrane is under 10 years old
- Damage was caused by an external event (like debris or hail)
If in doubt, professional inspection is always the first step.
Questions to Ask Your Roofer Before Choosing a Flat Roof
Before hiring a contractor or selecting a material, ask these essential questions:
- What’s the warranty on both labor and materials?
- Is this product tested for Utah snow loads?
- Are you certified to install this material?
- What’s the estimated maintenance over the life of the roof?
- Can I see examples of similar local projects?
Asking the right questions helps ensure you make a confident, informed decision.
Maintenance Schedule by Material
Understanding the maintenance each flat roof type needs will help you plan long-term care and protect your investment:
- EPDM: Inspect yearly for seam integrity and re-seal as needed
- TPO: Clean surface 1–2 times per year to maintain reflectivity and prevent buildup
- Modified Bitumen: Inspect twice a year for cracks or blisters, especially after winter
- BUR: Re-gravel or patch annually; inspect after storms
Proactive maintenance helps extend your roof’s lifespan and prevent costly repairs.
