Our Materials and Options for Commercial Flat Roof Installation

We offer a variety of flat roofing materials designed to meet different needs for commercial buildings. Each option has unique features related to cost, durability, and energy efficiency.

Single-Ply Membranes

Single-ply membranes are popular for flat roofs because they are lightweight and easy to install. These membranes are made from flexible sheets, such as TPO, PVC, or EPDM.


TPO is known for its heat-reflective properties, which can help reduce cooling costs. PVC is durable and resistant to fire and chemicals. EPDM is a rubber membrane that stands up well to weather and UV exposure.


These materials are usually installed in large sheets to minimize seams. Fewer seams mean less chance for leaks, which helps protect your building better.

Modified Bitumen Solutions

Modified bitumen is a type of asphalt roofing that has been improved with polymers to add strength and flexibility. It is usually applied in layers and can be hot-mopped or torch-applied.


This system offers strong waterproofing and is good for buildings with low slopes. It can handle temperature changes well without cracking.


Modified bitumen is often chosen for its resistance to wind uplift and durability. It can come with reflective coatings to improve energy efficiency as well.

Built-Up Roofing Systems

Built-up roofing (BUR) consists of multiple layers of bitumen and reinforcing fabrics. These layers are alternated to create a strong, waterproof surface.


This method has been used for many years and provides solid protection against water penetration. It is heavy but durable, suitable for commercial buildings with flat or low-slope roofs. Built-up roofing also offers good resistance to foot traffic, making repairs or inspections easier and safer.

Reflective and Energy-Efficient Options

Many commercial roofs now include materials designed to reflect sunlight and reduce heat absorption. Reflective coatings are often white or light-colored to shine off solar rays.


These options can lower energy costs by keeping buildings cooler in hot climates like Chino, CA. Some materials also meet ENERGY STAR standards, which can qualify a building for rebates and incentives. We can help you select coatings or membranes that improve your roof’s energy performance while maintaining durability.

Our Commercial Flat Roof Installation Process

To ensure proper installation of whatever material you pick, we follow a clear process to ensure your flat roof is installed correctly and lasts a long time. This includes inspecting your building, choosing the right materials, and carefully installing each layer.


Initial Inspection and Consultation


We start by inspecting your building’s current roof and structure. This helps us spot any damage or issues that need fixing before installation. During the consultation, we discuss your needs and budget. We also explain different flat roofing options so you can choose what fits best. We measure the roof precisely to plan how much material we’ll need. This step helps avoid extra costs or delays later.



Material Selection and Sourcing


We offer materials like TPO, EPDM, and modified bitumen, all known for durability and weather resistance. We help you pick the best material based on your building type, climate, and budget. Our goal is to balance cost and performance. Once you decide, we order high-quality products from trusted suppliers. This ensures materials are ready and meet industry standards.



Step-by-Step Installation Procedures


First, we prepare the roof by removing the old surface and cleaning debris. Next, we repair any damaged areas to create a smooth base. We install insulation to improve energy efficiency and prevent heat loss. Then, we apply a waterproof membrane to protect from leaks. Finally, we seal all edges and joints with special adhesives or tape. We do a thorough inspection to make sure everything is secure and meets safety codes.

Commercial Flat Roof Installation FAQs

  • How much does commercial flat roof installation cost in Chino, CA?

    Commercial flat roof installation typically costs $4 to $11 per square foot on average, including labor and materials. For a 10,000 square foot commercial building, owners can expect to pay between $40,000 and $90,000 depending on the material type. Factors affecting cost include roof size, material choice (TPO, EPDM, PVC), and whether tear-off is required. We provide transparent estimates tailored to your building's specific needs.

  • How long does commercial flat roof installation take?

    An average commercial roof installation takes one to five weeks. TPO and EPDM installations typically take 1 to 2 weeks for mid-sized buildings, while built-up roofing systems can take 3 to 4 weeks or longer. Timeline depends on roof size, complexity, and weather conditions. We work efficiently to minimize disruption to your business operations.

  • What are the best flat roofing materials for commercial buildings?

    The most common options are TPO ($4-$10 per square foot, 10-25 year lifespan), EPDM ($4-$10 per square foot, 15-20 years), and PVC ($5-$12 per square foot, 20-30 years). Each offers different benefits—TPO provides energy efficiency, EPDM offers durability and flexibility, and PVC delivers the longest lifespan. We'll help you select the right system for your budget and building requirements.

  • When should I replace my commercial flat roof?

    Replace your roof if you notice persistent leaks, ponding water lasting over 48 hours, visible cracks or bubbling, increased energy bills, or if your roof is 20-25 years old. If more than 25% of your roof is damaged, replacement is typically more cost-effective than repairs. Our team provides honest assessments to determine the most economical solution.

  • What are the benefits of flat roofs for commercial buildings?

    Flat roofs are cost-effective to install, provide accessible space for HVAC equipment and solar panels, and are easier to maintain than pitched roofs. They require fewer materials and have simpler structures, making them less expensive than steep slope roofs. They're ideal for California's climate and can accommodate reflective materials that reduce cooling costs and meet energy efficiency requirements.
