Installer: Spray Foam Arizona
Area: Statewide Arizona
Roof System: Closed-Cell Spray Polyurethane Foam (SPF) with Reflective Coating
Building Type: Commercial Metal Building
Climate Zone: Hot Desert (Arizona)
Project Overview
A commercial building owner in Arizona was facing high summer energy bills, uneven indoor temperatures, and roof performance issues due to an aging metal roofing system. With extreme desert heat pushing roof surface temperatures past 160°F, the HVAC system was forced to run continuously to maintain comfort.
The owner needed a solution that would:
Lower energy consumption
Improve indoor comfort
Prevent leaks
Avoid a costly full roof replacement
Deliver a strong long-term return on investment
The Spray Foam Roofing Solution
Spray Foam Arizona installed a closed-cell spray polyurethane foam roofing system directly over the existing roof, eliminating the need for tear-off. The system was finished with a high-reflectivity elastomeric protective coating to reduce solar heat absorption.
Key System Benefits
Seamless, fully adhered insulation layer
High R-value per inch (R-6.5 to R-7)
Air sealing and vapor resistance
Reflective white coating to reduce heat gain
Lightweight and ideal for metal structures
Minimal disruption to building operations
Energy Performance Results
After installation, the building showed measurable reductions in cooling demand and HVAC runtime, even during peak Arizona summer temperatures.
Before vs. After Results
Performance Metric | Before SPF Roof | After SPF Roof | Improvement |
Roof Surface Temperature | ~165°F | ~95°F | ↓ 70°F |
HVAC Runtime | High | Reduced | ↓ 25–40% |
Cooling Energy Consumption | Baseline | Lower | ↓ 28–35% |
Summer Monthly Energy Cost | ~$4,200 | ~$2,800–$3,000 | ↓ $1,200+ |
Indoor Temperature Stability | Inconsistent | Stable | Major Improvement |
Estimated Annual Energy Savings
$14,000–$18,000 per year
Why Spray Foam Roofing Reduces Energy Costs
1. Superior Thermal Insulation
Spray foam creates a continuous insulation barrier that dramatically reduces heat transfer through the roof — the largest heat-gain surface in desert climates.
2. Complete Air Sealing
Unlike board insulation or traditional roofing systems, SPF eliminates seams and gaps where hot air infiltrates, improving HVAC efficiency.
3. Solar Reflectivity
The bright white elastomeric coating reflects sunlight, reducing rooftop heat buildup and lowering interior cooling loads.
4. Reduced HVAC Wear
Lower heat gain means HVAC systems cycle less frequently, reducing maintenance costs and extending equipment life.
Additional Benefits Beyond Energy Savings
Extends roof lifespan
Prevents leaks with a seamless waterproof membrane
No tear-off = less landfill waste and downtime
Lightweight system ideal for metal and commercial structures
Improves occupant comfort and temperature consistency
Reduces carbon footprint and energy demand
Qualifies for potential energy efficiency incentives
ROI & Payback Snapshot
Category | Estimated Value |
Project Investment | $120,000 (example) |
Annual Energy Savings | $14,000–$18,000 |

In many Arizona buildings, spray foam roofing pays for itself through energy savings — while eliminating future roof replacement costs.
Customer Testimonial
"After installing our spray foam roof, our energy bills dropped almost immediately. The building stays cooler, our air conditioning runs less, and we eliminated roof leaks at the same time. It’s one of the best upgrades we’ve made."
