Yavapai Roofing specializes in the installation of all types of low slope roof systems found in Arizona. Our expertise includes PVC, TPO, modified bitumen, and roof coatings over existing roofs. Commonly called flat roofs by homeowners, these roofs technically still have a slope to them, required by code for drainage of the roof. We are committed to providing high-quality, durable roofing solutions tailored to the unique climate and needs of Arizona, from the desert to the mountains.
ABOUT FLAT ROOFING SYSTEMS
Flat roofs are unique compared to roofs with steep slopes. The quality of installation and materials must be exceptionally high to prevent leaks or premature wear. In the Prescott area, flat roofs require specialized knowledge and expertise due to the ice and snow, whereas in Phoenix, low slope roofs face months of sunshine. Yavapai Roofing has the experience and capacity to install a flat roof system that will stand the test of time.

SINGLE PLY MEMBRANE ROOFING

Single-ply membrane roofing is an excellent option for many commercial and residential properties. This roofing type involves a synthetic single-ply material installed over your roof, slightly drained to allow water to exit via scuppers or roof drains. Common materials used include TPO, PVC, and EPDM.
Advantages:
- Durability in harsh weather conditions
- Excellent performance against ice and snow
- Energy efficiency when installed with insulation board
- Reflective against the sunlight to help with energy efficiency
Disadvantages:
- Can be punctured by heavy traffic or carelessness by people on the roof
Installation Process:
- Preparation: Cleaning the roof deck thoroughly.
- Insulation: Optional insulation board for energy efficiency.
- Taper Board: Helps with drainage and prevents standing water.
- Cover Board: Protects insulation and provides a surface for the membrane.
- Membrane Application: Rolled out over the roof and up parapet walls, with seams heat welded for TPO or PVC, or chemically adhered for EPDM.
As a GAF Master Contractor, we can offer warranties of up to 30 years on your commercial TPO or PVC roof when using GAF materials.

MODIFIED BITUMEN ROOFING IN NORTHERN AZ
Modified bitumen roofing is another excellent option for low slope roofs. Made from materials similar to asphalt shingles, modified bitumen comes in 3-foot wide rolls, ensuring it holds up well against the sunlight, ice, and snow typical across Arizona.
Advantages:
- Durability and longevity (15-20 years)
- Excellent performance in harsh weather
- Option to extend lifespan with coatings
Disadvantages:
- Requires skilled installation labor
Installation Methods:
- Base Layer: Adhered to the roof deck via heat or cold application methods.
- Additional Layers: Can include more base layers or the final layer.
- Torch Down Method: Preferred for its durability, though alternative cold application techniques are used during fire bans.
SPRAY FOAM ROOFING
Spray foam roofing is another type of roofing commonly found here in Arizona, especially in the valley around Phoenix. For the right building, foam can be a great choice.
Advantages:
- Insulative value – foam roofing can be applied at various thicknesses to add insulative value to your roof
- Reflectivity – the coating used on foam is normally white in color to reflect sunlight
- Option to extend lifespan with coatings
- Inexpensive – foam can be cheaper and quicker to install on your roof than any other complete roofing system
- Lightweight – foam doesn’t add much additional weight on your structure
Disadvantages:
- Must be re-coated frequently to maintain its structural integrity
- If water is able to get into the foam, it soaks it in like a sponge, leading to more extensive issues
- Higher skill required to install properly – the installer must not create areas of water ponding that will lead to issues later on
Installation Methods:
- Foam is applied through a sprayer. The sprayer is connected to a mixer that mixes two parts to create the end product, sprayed onto the roof, and then allowed to expand and dry. Then, the coating is applied, normally an acrylic elastomeric, in at least two coats.

ROOF COATINGS IN ARIZONA
Roof coatings can significantly extend the life of an existing flat roof. Common coatings include aluminum, silicone, and, to a lesser extent, acrylic.
Types of Roof Coatings:
- Aluminum Coating: Used over modified bitumen roofs to reflect sunlight and facilitate drainage.
- Silicone Coating: Creates a completely watertight barrier, lasting up to 20 years, and performs exceptionally well against ice, snow, and standing water.
- Acrylic Coating: Less preferred due to its vulnerability to standing water, which can cause deterioration and leaks.
WHAT IS THE BEST TYPE OF LOW SLOPE ROOF SYSTEM IN ARIZONA?
As you can see, there are many options for low slope roofs here in Arizona. Part of it depends on which part of the state you are located in – some types of low slope roofing perform better in dry, sunny areas like Phoenix or Glendale, whereas others will last longer in snowy places like Flagstaff. For coatings, the biggest variable is the condition of your existing roof and what type of weather it will face. It’s important to understand the variables and what will work best for your specific situation – feel free to contact us for a free evaluation and solution for your specific roofing needs. Let’s dive into some general information to help guide you on the right type of roofing system for your low slope roof:
- TPO, PVC, and modified bitumen will work well for any of the climate zones here in Arizona. Whether you are located in Scottsdale and want the high reflectivity of a white PVC, or in Flagstaff and want R-38 insulation added to your roof along with a durable TPO roof membrane, any of these three will last for years. They’ll handle anything from hot, sunny days to freezing winter nights. For TPO, PVC, and modified bitumen on commercial buildings, you can also add a 20 to 30 year manufacturers warranty on your roof, meaning in the case of any leaks, defects, or issues, the manufacturer will cover the associated repair costs for that period of time. For residential applications, these warranties are not as readily available, however, you can rest assured the system is installed to the same specifications and standards as any commercial building.
- We’ve found that foam roofing seems to hold up best in the drier, warmer climates of Arizona, such as Phoenix. It doesn’t seem to hold up well in direct contact with freezing ice and snow that sit on it for periods of time, expanding and contracting against it. Over time, this begins to lead to issues…we’ve seen several roofs around the Prescott area that have foam applied that have multiple leak areas due to this. However, in the valley, where it’s not subjected to ice and snow, foam can be a great choice. With foam, the most important factor is the type of coating that is applied. Most installers will apply what is called a 10-year coating system that will carry a 10 year manufacturers warranty against defects. However, there are often caveats in the warranty language that indemnify the manufacturer against areas of water ponding, which acrylic is not resistant to. This is why it’s important to hire a licensed foam applicator and do your homework on them.
- Coatings – there are two primary types of roof coatings we use for low slope roofs, acrylic elastomeric and silicone. Acrylic elastomeric is less costly, but won’t carry as long of manufacturers warranties and doesn’t hold up well against ponding water or prolonged water contact, similar to paint. Silicone is slightly more expensive, but will hold up better against ponding water and is eligible for longer manufacturer warranties, up to 20 years. Normally, we can repair areas of ponding to prevent issues with that, so the bigger factor is what type of warranty you are looking for. Silicone is our preferred coating due to its longevity and resistance to ponding water, but if you are on a budget, acrylic elastomeric can be a good choice that will last for 7-10 years.
