Is Spray Foam Roofing Right for Your Phoenix Property?

If you own a building with a flat roof in Phoenix, spray foam roofing might be one of the smartest investments you can make. It’s affordable, energy-efficient, and incredibly durable—making it a top choice for both commercial and residential properties.

At Pinnacle Roofing, we specialize in high-quality spray foam roof systems backed by 25+ years of hands-on experience and trusted customer service across the Valley.

Here’s what to know about installing spray foam over an existing roof—and whether it’s the right fit for your building.

What Is Spray Foam Roofing?

Spray foam roofing isn’t a single material—it’s part of a multi-layer system designed for maximum performance in Arizona’s extreme climate. The installation includes:

• A clean roof surface (deck or existing roof)

• Spray polyurethane foam (SPF)

• Protective coatings

• Optional granules for UV protection and added durability

Using high-pressure equipment, we spray a mixture that expands instantly to form a seamless, waterproof layer. The result? A strong, lightweight, and high-R-value roofing system that provides outstanding insulation and moisture protection.

Can You Install Foam Over an Existing Roof?

In many cases, yes! Installing spray foam over an existing flat roof can be a cost-effective and convenient alternative to a full roof replacement—but it depends on the condition of the current roof and the type of materials already in place.

Let’s break down the pros and cons.

Pros of Installing Spray Foam Over an Existing Roof

✅ Cost-effective – Foam over an existing roof is more affordable than full removal and replacement.

✅ Faster, less disruptive – No loud tear-off process, and less mess for building owners or tenants.

✅ Versatile application – Works on flat, low-slope, or irregularly shaped roofs.

✅ Eco-friendly – Less waste in landfills and improved energy efficiency reduces your carbon footprint.

When Spray Foam Overlays Aren’t a Good Fit

While spray foam roofing is flexible, it’s not for every situation. Here are some common issues:

• Poor roof condition – If the existing roof is wet, damaged, or unstable, it must be repaired or replaced first.

• Incompatible roof systems – Some roofs, like loosely-adhered TPO membranes, don’t provide a stable enough base.

• Code limitations – Most local codes only allow two roofing layers. If your building already has two, one may need to be removed first.

That’s why it’s crucial to schedule a roof inspection with a qualified contractor before deciding.
