Flat Roofing in Tucson, AZ: Top Choices for Durability and Energy Efficiency

At Tucson Roofing Company, we know flat roofs are a top pick for homes and businesses in our sunny city. They look great and work well in our hot, dry climate. We offer many flat roofing options to fit different needs and budgets.


Flat roofs can save energy and money. They can last 10 to 20 years with proper care, making them a smart long-term choice. Our team has years of experience installing and fixing flat roofs in Tucson.


We use high-quality materials built to handle Arizona's harsh sun and rare but heavy rains. From basic repairs to full replacements, we do it all. Our experts can help you choose the best flat roof system for your property.

Choosing Your Flat Roof Material

Selecting the right flat roof material is crucial for Tucson's hot, dry climate. We'll explore three popular options that offer durability and protection for your home or business.

Built-Up Roofing (BUR) Systems

Built-up roofing is a time-tested option for flat roofs. It consists of multiple layers of bitumen and reinforcing fabric. The top layer is usually gravel or a reflective coating.



BUR systems are known for their durability. They can last 20-30 years with proper maintenance. These roofs handle foot traffic well, making them ideal for rooftop equipment access.


We recommend BUR for its excellent waterproofing abilities. It's also fire-resistant, which is important in Tucson's dry conditions. The multi-layer construction provides good insulation too.


One drawback is the weight. Some structures may need reinforcement to support a BUR system. Installation can be messy and smelly due to the hot tar used.

Single-Ply Membranes

Single-ply membranes are lightweight and easy to install. The two main types are:


  • EPDM (Ethylene Propylene Diene Monomer)
  • TPO (Thermoplastic Polyolefin)


EPDM is a rubber-like material that's very durable. It resists UV rays and extreme temperatures well. TPO is a plastic-based material that reflects heat, helping to keep buildings cooler.


Both options are popular for Tucson's flat roofs. They're flexible and can handle building movement without cracking. Installation is quick and clean compared to BUR.


These membranes are lightweight, so they don't need extra structural support. They come in large sheets, reducing the number of seams where leaks could occur.

Spray Polyurethane Foam (SPF)

SPF is a modern roofing solution that's gaining popularity. It's sprayed on as a liquid and expands into a foam, creating a seamless layer.



This material offers excellent insulation. It can lower energy bills by keeping heat out in summer and in during winter. SPF conforms to any roof shape, sealing around vents and other protrusions.


We find SPF particularly suited to Tucson's climate. It reflects UV rays and resists water pooling. With proper maintenance, an SPF roof can last over 50 years.


The initial cost of SPF can be higher than other options. But its energy efficiency and longevity often make it cost-effective in the long run. It requires professional application for the best results.

Fundamentals of Flat Roofing

Flat roofs are a popular choice in Tucson due to their unique benefits and suitability for the local climate. These roofing systems use specific materials designed to withstand the Arizona sun and occasional heavy rains.


Benefits of Choosing a Flat Roof


Flat roofs offer several advantages for Tucson homeowners and businesses. They are energy efficient, helping to keep buildings cool in the hot desert climate. This can lead to lower air conditioning costs and improved comfort.


Flat roofs also provide extra usable space. Many property owners use their roof for outdoor living areas, solar panel installations, or rooftop gardens. This makes them a versatile option for both homes and commercial buildings.


Maintenance is often easier on flat roofs. We can inspect and repair them more safely than steep-sloped roofs. They also tend to be less expensive to install and maintain over time.


Materials Used in Flat Roofs


We use several types of materials for flat roofs in Tucson:


  • Built-up roofing (BUR): Layers of bitumen and reinforcing fabric
  • Modified bitumen: Asphalt mixed with rubber or plastic modifiers
  • EPDM: A durable synthetic rubber membrane
  • TPO: A single-ply roofing membrane that reflects heat
  • Elastomeric coatings: Flexible, waterproof layers that can extend roof life


Each material has its own strengths. BUR and modified bitumen are very durable. EPDM and TPO resist UV rays well. Elastomeric coatings can help seal and protect existing roofs.


We choose the best material based on the building's needs, budget, and local weather conditions. Our goal is to provide a roof that will perform well in Tucson's unique climate.

Innovative Flat Roof Technologies

Flat roofing has come a long way in recent years. New materials and techniques are making these roofs more durable and energy-efficient than ever before.

Energy-Efficient Roofing

We offer cutting-edge energy-efficient options for flat roofs in Tucson. Cool roofing materials reflect more sunlight and absorb less heat than standard roofs. This helps keep buildings cooler and reduces air conditioning costs.


Some popular choices include:


  • White or light-colored coatings
  • Reflective membranes
  • Green roofs with plants


These materials can lower roof temperatures by up to 50°F compared to traditional dark roofs. The energy savings can be substantial, especially during Tucson's hot summers.


We also recommend adding extra insulation under the roofing material. This further improves energy efficiency year-round.

Solar Panel Integration

Flat roofs are ideal for solar panel installation. We can design your roof to maximize solar potential.


Modern roofing systems allow for seamless integration of solar panels. Options include:


  • Built-in solar tiles
  • Lightweight panel mounts
  • Ballasted systems that don't penetrate the roof



Solar panels can significantly reduce electricity bills. In sunny Tucson, a properly designed system may even produce excess power to sell back to the grid.


We carefully plan panel placement to avoid shading issues. Our designs also ensure easy roof access for maintenance.

FAQs on Flat Roofing

Flat roofing in Tucson comes with unique considerations due to the local climate. We've compiled answers to common questions about maintenance costs, longevity, and installation times for different flat roof options in the area.

  • How does climate affect flat roofing options in the Tucson area?

    The hot, dry climate in Tucson can be tough on flat roofs. UV rays and high temperatures can cause materials to break down faster. We recommend reflective coatings to help protect roofs from the sun.


    Heat also causes expansion and contraction of roofing materials. This can lead to cracks and leaks over time. We use flexible membranes that can withstand temperature changes better than rigid materials.

  • What are the estimated maintenance costs for different flat roofing systems?

    Maintenance costs vary depending on the roofing material. Single-ply membranes like TPO or EPDM tend to have lower maintenance costs. We estimate $0.10 to $0.25 per square foot annually for these options.


    Built-up roofing and modified bitumen systems may cost more to maintain. Expect to pay $0.15 to $0.35 per square foot each year for upkeep on these types of roofs.

  • Can you compare the longevity of various flat roof solutions?

    The lifespan of a flat roof can vary greatly based on the material and maintenance. TPO and EPDM membranes typically last 20-30 years with proper care.


    Built-up roofing and modified bitumen can last 15-25 years. Metal roofing is very durable, often lasting 40-50 years or more in Tucson's climate.

  • What are the installation time frames for common flat roofing types?

    Installation times depend on the size of the roof and the material chosen. For a typical home, single-ply membranes like TPO or EPDM can be installed in 1-3 days.


    Built-up roofing and modified bitumen systems take longer, usually 3-5 days for installation. Metal roofing may take 5-7 days to install on a residential flat roof.
