Written by Susan Raisanen | Aug. 12, 2024

Foam roofs are popular in Phoenix and Scottsdale, and for good reason! They’re known for their amazing insulation, durability, and bang-for-your-buck value.

But to keep your foam roof in tip-top shape, regular maintenance and recoating are key. Dive into this guide, where we answer your questions about foam roof upkeep, including how long a foam roof lasts, when to recoat, and what coating to use. Let’s get started!

 

How Long Does a Foam Roof Last in Arizona?

Foam roofs, also known as Spray Polyurethane Foam (SPF) roofs, are rockstars when it comes to durability and longevity. But with Arizona’s intense sun, scorching temperatures, and the occasional monsoon, how does a foam roof hold up?

Foam Roof Life Expectancy

With the right care, a foam roof can perform like it should for 20 to 30 years. The foam roof's life expectancy hinges on regular check-ups and timely fixes. Small cracks or dents? No biggie—just patch them up to keep things running smoothly. And remember, Arizona’s UV rays can be tough, so staying on top of maintenance is a must.

How to Make Sure Your Foam Roof Lasts

In addition to addressing minor damage promptly, regular cleaning and inspections play a crucial role in extending the life of your foam roof. Dust, debris, and leaves can accumulate on the roof, leading to water pooling and potential damage.

By keeping the surface clean and free from obstructions, you can ensure proper drainage and prevent unnecessary wear and tear.

Another factor that contributes to the longevity of a foam roof is the quality of the initial installation. Working with experienced and reputable roofing contractors ensures that the foam is applied correctly, providing a strong foundation for long-term durability.

Proper installation also minimizes the risk of issues arising from poor workmanship, such as uneven foam application or inadequate bonding.

 

What Can Affect the Life Expectancy of a Foam Roof?

  1. Maintenance: Regular TLC, like inspections and cleaning, can keep your foam roof going strong.
  2. Weather: Sun, heat, and rain can wear down your roof, but elastomeric coatings can shield it from the elements.
  3. Coating: The right foam roof coatings make all the difference in durability.
  4. Temperature Fluctuations: High heat and sudden temperature drops can cause expansion and contractions. Elastomeric coatings are flexible and resilient, preventing cracking and splitting. 
  5. Proper Drainage: Prevent water pooling to avoid leaks and structural damage by regularly checking and clearing gutters and downspouts. 
  6. Pollution and Airborne Contaminants: High levels of pollution lead to build-up on the roof's surface, causing wear and tear. Periodic cleaning and protective coatings can help to avoid this. 

 

How Do You Maintain a Foam Roof?

Keeping your foam roof in top condition doesn’t have to be a chore. Here’s how to make it easy and breezy.

Regular Inspections

Have your roof checked for wear and tear twice a year, especially after wild weather. During inspections, your trusted pro will pay close attention to areas around roof penetrations, such as vents, skylights, and HVAC units.

These spots are more prone to leaks and damage. They'll also inspect the seams and edges of the roof, as these areas can be vulnerable to separation or deterioration over time.

Cleaning

Keep the roof clean by sweeping off debris, dirt, and leaves. Use a soft-bristle brush or a low-pressure washer to avoid damaging the foam.

In addition to regular cleaning, consider scheduling a professional cleaning service once a year. Professionals have the expertise and equipment to thoroughly clean the roof without causing damage. They can also spot potential issues that may not be visible to the untrained eye, ensuring that your roof remains in optimal condition.

Repairs

Got a crack or hole? No worries. A foam roof sealant can do the trick for small repairs. To ensure the job is done to standard, call in a pro for foam roof repair.

When addressing repairs, it's important to use high-quality materials that are compatible with the foam roofing system. Using the wrong type of sealant or repair material can lead to further damage and reduce the effectiveness of the repair.

If you're unsure about the best approach, consulting a professional roofer can help ensure that the repair is done correctly and effectively.

Regularly inspecting and maintaining the flashing around roof penetrations is also crucial. Flashing is the material used to seal the edges of roof penetrations, and it plays a vital role in preventing leaks.

Over time, flashing can deteriorate or become dislodged, so it's important to check and repair it as needed to maintain a watertight seal.

 

What is the Best Coating for a Foam Roof?

For maximum protection and longevity, elastomeric coating is the way to go. Elastomeric coatings are specifically designed to enhance the performance and longevity of foam roofs on both homes and commercial buildings.

They form a protective barrier that not only shields the foam from UV radiation but also provides resistance to water and moisture. This dual protection helps maintain the roof's structural integrity and prevents issues such as cracking, splitting, and water infiltration. Let's talk about why. 

Benefits of Elastomeric Coating

  1. UV Protection: Shields your roof from harmful UV rays.
  2. Waterproofing: Keeps leaks and water damage at bay.
  3. Flexibility: Stretches and bends with the weather, preventing cracks.
  4. Durability: Adds years to your foam roof’s life.

 

How Often Should a Foam Roof Be Recoated?

Recoating your foam roof is like giving it a fresh suit of armor. But how often does it need a new coat?

Recommended Recoating Schedule

Typically, you should recoat your foam roof every 5 to 10 years. But it can depend on a few factors:

  1. Climate: Arizona’s UV rays mean you might need to recoat more often.
  2. Roof Condition: Regular inspections will help you decide if it’s time for a touch-up.
  3. Coating Quality: High-quality coatings last longer and need fewer reapplications.
  4. Industrial Pollutants: Pollutants can degrade your coating, making a recoat necessary sooner. 
  5. Complex Designs: Complex designs may have more penetrations, like vents and skylights, requiring more frequent recoating to maintain optimal protection. 

Applying a fresh coat of elastomeric coating not only enhances the roof's protective capabilities but also revitalizes its appearance. Over time, the coating can become discolored or worn, affecting the overall aesthetics of the building. Recoating restores the roof's appearance, giving it a fresh and clean look.

When Should I Recoat My Roof?

Timing is everything! Knowing when to recoat your foam roof can save you headaches down the road.

Signs You Need to Recoat

  1. Visible Wear: Is the coating looking thin or worn out?
  2. Cracks and Blisters: Spot any cracks or bubbles? Time to recoat.
  3. Water Pooling: If water isn’t draining well, it’s a sign your coating needs a refresh.
  4. Age: Is your foam more than 5 years old? It's a good idea to schedule an inspection. 

What's the Best Time of Year to Schedule a Recoat?

Seasonal weather patterns can also impact the timing of recoating. In Arizona, it's best to schedule recoating during the cooler months when temperatures are more moderate.

Extreme heat can affect the application and curing process of the coating, potentially compromising its effectiveness. Planning recoating projects during spring or fall ensures optimal conditions for successful application.

Professional Assessment

Not sure if it’s time? Get a pro to take a look. They’ll give you the lowdown on your roof’s condition and the best way forward.

A professional assessment provides valuable insights into the overall health of your foam roof. Roofing experts can identify issues that may not be immediately visible, such as underlying moisture damage or areas of weakened foam.

They can also recommend the most suitable type of coating based on your roof's specific needs and environmental conditions.

During the assessment, the roofing professional will perform a thorough inspection, checking for signs of wear, damage, and deterioration. They may also conduct tests to evaluate the adhesion and performance of the existing coating.

Based on their findings, they will provide a detailed report and recommendations for recoating or other necessary maintenance.

How Often Does a Foam Roof Need to Be Replaced?

Even the best roofs have a shelf life. Here’s when to think about foam roof replacement.

Replacement Frequency

A well-maintained foam roof can last 20 to 30 years. Factors influencing replacement include:

  1. Maintenance History: A well-cared-for roof lasts longer.
  2. Environmental Factors: Harsh weather can shorten its lifespan.
  3. Quality of Installation: Proper installation means a longer-lasting roof.
  4. Structural Modifications: Significant changes, like the addition of heavy equipment or other alterations, will require a professional assessment. 

Signs It’s Time for Replacement

  1. Severe Damage: If the damage is too extensive to fix.
  2. Frequent Leaks: Persistent leaks mean it’s time for a new roof.
  3. Age: If your roof is nearing 30 years, it might be time for a change.
  4. Performance: If there's a decline in energy efficiency or a change in indoor temperatures despite regular maintenance.
