What is Spray Polyurethane Foam?

Spray polyurethane foam (SPF) is a two-component material formed by mixing isocyanate (Component A) and polyol (Component B) using heat and pressure. When these chemicals are sprayed in liquid form, they react upon contact to create a solid, lightweight, and fully adhered roofing membrane. Although spray foam has been available for many years, it remains relatively unfamiliar to many facility managers and property owners.


SPF has been utilized across various industries since the 1940s, but it gained traction in the roofing and construction sectors in the late 1970s due to its exceptional insulating properties. Modern spray polyurethane foam roofing comes in two varieties: open-cell and closed-cell. Closed-cell foam is mainly employed in commercial roofing applications, while open-cell foam is generally used for interior insulation and soundproofing.

The Spray Foam Roofing Essentials

In the spray foam roofing process, Components A and B are mixed and applied directly on-site using a specialized spray foam rig. The two chemicals, stored in separate containers, are pumped through high-pressure hoses to a mixing gun at temperatures ranging from 115 to 130°F. Maintaining the right levels of heat and pressure is crucial for a successful application.

 

As the foam cures, it hardens into a durable, seamless, lightweight, and waterproof membrane. SPF boasts the highest R-value (thermal resistance measure) of any commercial roofing material, making it suitable for various climates.

UV Performance

Although SPF serves as an outstanding waterproofer and insulator, it provides minimal protection against the sun's harmful rays. To address this issue, the foam should be coated with an elastomeric or acrylic roof coating. If you live in Tucson, it is not recommended that you use silicone your spray foam roof because our climate is too dry for silicone roof coatings to perform properly. 

There are high quality acrylic / elastomeric roof coatings on the market that are designed for Tucson's arid environment. Regular maintenance and inspections are key to ensuring that your SPF roof's coating remains effective, especially during monsoon season.

Pros of Spray Foam Roofing

Thermal Resistance

Spray foam roofing insulation's the highest R-value of any conventional roofing material (that isn't polyiso). R-Value measures a material's ability to resist the flow of heat. The R-value of roofing grade SPF is approximately 6.5 per 1 inch. However, when you combine this with a reflective roof coating, it is widely held that SPF provides far greater insulation qualities than its R-value suggests.

Strength & Durability

Spray foam systems provide commercial and residential roofs with an incredibly strong, yet remarkably lightweight, protective membrane. In fact, SPF systems, applied at a thickness of 1 inch or greater, are proven to improve a building's structural integrity.

Longevity

A properly installed and maintained SPF roof system can last 20-35+ years, if not longer. SPF roofs must be recoated every 5-10 years depending on the quality of roof coating. This will ensure that UV rays don't degrade the roof's foam layer.

Seamless & Self Flashing

Unlike conventional roofing systems, spray foam roofs are completely seamless and self flashing. SPF is specially designed to conform and adhere to irregular shapes and surfaces. These qualities eliminate the ability for water to enter sensitive areas of the roof like: seams, fasteners, penetrations, and more.

Quick Installation

Compared to most other conventional roofing materials, SPF systems can be installed more quickly and are far less disruptive to building and home occupants. Most of the time spray foam roofs can go directly over your existing roof. (Max. 2 roofing layers allowed in Tucson)

Renewable and Sustainable

Because SPF roofs can be recoated numerous times, they produce little to no waste over the course of their lifespan. This offsets landfill waste concerns and high costs that normally accompany a roof replacement.

When does a roof system reach the end of it's lifecycle?

The lifecycle or lifespan of your desert roofing system depends on a few factors:

  • Quality of material

  • Roof ventilation

  • Quality of the Install

  • Maintenance habits

If your roof appears to have signs of decay... Odds are it's reached the end of its lifespan. Here's how long each roof system can last; but in Tucson, Arizona.

20-30 Years

  • Architectural Shingles

  • Tile roof w/ Premium Underlayment​

  • Built-Up Roof w/ premium roof coating

  • ​TPO Roof 

10-15 Years

  • Single-Ply Built-Up roof w/ elastomeric coating

When do I know I need a new roof?

Waiting for your roof to start leaking doesn't make it last any longer, this only increases your chances of mold growing. On the other hand, some homeowners are skeptical because they've ran across dishonest or inexperienced contractors. 

Some roofing systems in Tucson, such as: built-up roofs, spray foam roofs, some metal roofs, and TPO roofs can be restored when they get closer to that lifespan expiration date. 

Signs that your roof is on it's last breath

Loss of granules, missing shingles, curling/buckling, cracks, fiber-wire sticking through, and heavy storm damage

Shingle Roof

Pooling/standing water, "soft"/spongy areas, excessive amounts of black tar/adhesives visible heavy storm damage

Built-Up Roof w/ Elastomeric Coating

If your roof is leaking and you have silicone coating, the only option is to replace. Unfortunately nothing, not even silicone, adheres to silicone :(

Built-Up Roof w/ Silicone Coating

Your spray foam has huge blisters, unevenness that traps water, and/or is completely exposed and drying up.

Spray Foam Roof w/ Coating

Fasteners are failing / falling, rust, and buckling

Corrugated / Ribbed Metal Panels

The underlayment beneath the tiles is the most vital component. The only way it's condition is to have an experienced roofing contractor inspect your tile roof's underlayment.

Tile Roof

*Blown off tiles are not signs that you need all new tiles*

Concrete/Clay tiles them are designed to last 50+ years. They are natural materials w/ no watertightness warranty. 

Did you know?

When should I replace my roof?

A reputable contractor should advise you to look into replacing your roof when you've reached about 80% of its lifespan. This is because our dry heat affects all building components and tends to accelerate your roof's lifespan.

For the new roof, you may want to look into a Cool Series material or something more flexible than you had before. Flexible & reflective roofs perform best in Tucson's climate.

It pays to be proactive

Interior leaks should be treated as a high importance matter for the sake of your health. Trapped moisture eventually grows into mold and this can spread, the longer you wait to fix your roof. 

Roofs should be inspected at least twice per year to ensure that nothing is affecting the system from keeping 100% of moisture out. Keep in mind, materials can't do their job if they are not properly maintained.

Not even the toughest of roofs can survive a really bad monsoon storm.

If a recent storm has affected your area, it is likely that your entire roof system may have been affected. You should not rely on what your eyes can see from the ground. If your neighbors are chirping about it, you should likely get your roof checked, too.

Storm damages are covered by your insurance provider

If you have homeowner's insurance, your roof likely covered by your policy provider. You must act fast because they may hold you accountable for lack of damage mitigation.

 

If your roof blew off, make sure to:

  1. Mitigate / Control the Damage. Tarps and sandbags are ideal for this.

  2. File A Claim

  3. Meet w/ Your Adjuster

  4. Do your research on local roofers

  5. Collect Insurance Funds

  6. Hire a Roofing Contractor

Pitched Roof Components

Universal Roof Components

Roof Decking

This is the roof substrate (sheathing). The most common decking types in Tucson are: OSB, CDX, CCX, Plank boarding and tongue/groove. This is the structural component that attaches to your home's trusses.

Ice & Water Barrier

This barrier adds an extra layer of protection to your roof's most sensitive areas. Things like transitions, valleys, and pitch breaks should all get this material.

Roof Flashings

Cricket

This structural component diverts water away from walls and other vertical changes on your roof. These are most common on chimneys and flat roofs with parapet walls.

These are typically made of metal and are roofing components designed to shield joints and other components from water intrusion. Examples are: drip edge, valley, Z-bar, & counter flashings.

Flat Roof Components

Underlayment

This is the vapor barrier that goes directly above your decking to provide additional protection to your roof system. This is the main component for waterproofing tile roof systems

Pipe Boots

These terminate the round tubes that stick out of your roof. A metal/rubber boot protects this vertical joint from leaking.

Ridge Cap

This is the trim piece of roof material installed where two slopes meet to form the "ridge/hip".

Roof Vents

These vents allow fresh air to regulate the temperature of your crawl/attic space. Usually "T-Tops", Static Vents, Mechanical Vents, Ridge Vent, etc.

  • What are the best roofing materials for roof replacement in Tucson?
    At ABRC, we understand that Tucson's unique climate conditions, including intense sun, heat, and occasional monsoon rains, can be tough on roofs. The best roofing materials for roof replacements in Tucson are those that offer durability, energy efficiency, and resilience against these harsh elements. Here are our top recommendations: 1. **Tile Roofing:** Clay or concrete tiles are exceptionally durable and can withstand high temperatures without suffering damage. They also provide excellent insulation, helping to keep your home cooler during the sweltering summer months. Plus, they're available in various colors and styles, adding a beautiful aesthetic to your home. 2. **Metal Roofing:** Metal roofs are highly resistant to extreme weather conditions and can last up to 50 years or more. They reflect the sun’s rays, which helps in reducing cooling costs. Metal roofing is also lightweight and can often be installed over existing roofing, making it a convenient option. 3. **Asphalt Shingles:** While they may not be as long-lasting as tile or metal, asphalt shingles are a popular and cost-effective choice. They are available in a variety of colors and styles, making them versatile for different home designs. Modern asphalt shingles can be made with higher durability to better withstand Arizona’s climate. 4. **Thermoplastic Polyolefin (TPO) Roofing:** For flat or low-sloped roofs, TPO roofing is an excellent choice. It offers great heat-reflective properties, which help reduce energy costs, and is resistant to UV radiation, chemical exposure, and punctures. TPO roofing can also accommodate the installation of solar panels, which is increasingly popular in Tucson. At ABRC, we take pride in offering roofing solutions that not only protect your home but also enhance its overall energy efficiency and aesthetic appeal. Our team of experts is here to help you choose the best materials tailored to your needs, ensuring long-lasting performance and satisfaction.
  • What happens to my old roof when ABRC installs a new one?
    When we install your new roof, our team will first conduct a thorough inspection to assess the condition of your old roof. If your old roofing materials can be salvaged, we will carefully remove and recycle them whenever possible, contributing to environmental sustainability.

Our goal is to minimize waste and leave your property clean and ready for its new, high-quality roofing system provided by ABRC. Your satisfaction and the health of our planet are our top priorities!
  • Does a new roof system need maintenance?
    Yes, even a new roof system requires regular maintenance to ensure its longevity and optimal performance. At ABRC, we recommend scheduling routine inspections and maintenance at least twice a year. While a new roof is built to last, factors such as weather, debris accumulation, and natural wear and tear can impact its condition. Our professional maintenance services include checking for and addressing minor issues like loose shingles, inspecting for leaks, cleaning gutters, and ensuring proper ventilation.

Contact ABRC today to learn more about our comprehensive maintenance plans tailored to your new roofing system.

Cons of Spray Foam Roofing

Costs

It's hard to find a good spray foam roofing contractor in Tucson. Hiring a reputable contractor that will stand by their work will come at a luxury.

UV Exposure

SPF roof systems are not designed to withstand much exposure to the elements. Spray foam roofs rely heavily on the elastomeric or acrylic roof coating to reflect UV rays and protect the roof from system failure.

Low Hail Impact Rating

Though spray foam roofs are solid, Tucson hail storms tend to impact the coating due to the density of the foam roof material when compared to other flat roof options. To offset this issue, you can add granules to your reflective roof coating.
