When it comes to commercial roofing, several options are available, each offering unique benefits in terms of durability, cost-effectiveness, and energy efficiency. Here are some popular options for new commercial roofing installation:

1. Built-Up Roofing (BUR): Built-up roofing, also known as tar and gravel roofing, consists of multiple layers of bitumen and reinforcing fabrics topped with a layer of gravel or mineral granules. BUR systems provide excellent waterproofing and UV protection and are known for their durability and longevity.

2. Single-Ply Membrane Roofing: Single-ply membranes, such as TPO (thermoplastic polyolefin) and PVC (polyvinyl chloride), are popular choices for commercial roofing due to their lightweight, flexibility, and ease of installation. These membranes offer excellent resistance to UV rays, chemicals, and punctures, making them ideal for flat or low-slope roofs.

3. Metal Roofing: Metal roofing systems, typically made of steel, aluminum, or copper, are known for their longevity, strength, and low maintenance requirements. Metal roofs can be installed in various styles, including standing seam, corrugated panels, and metal shingles, offering versatility and aesthetic appeal.

4. Modified Bitumen Roofing: Modified bitumen roofing is a type of asphalt-based roofing membrane reinforced with modifiers, such as polyester or fiberglass, to enhance strength and flexibility. This roofing system is known for its excellent weather resistance and durability, making it suitable for high-traffic commercial buildings.


When repairing for your commercial property`s, consult with a commercial roofing specialist.

TPO (thermoplastic polyolefin) roofing is a popular choice for commercial roofing applications due to its durability, energy efficiency, and ease of installation. Here are some key features and benefits of TPO roofing:


1. Durability: TPO roofing membranes are highly durable and resistant to punctures, tears, and impacts, making them suitable for high-traffic areas and harsh weather conditions. They can withstand exposure to UV radiation, ozone, and chemicals without degrading or becoming brittle over time.

2. Energy Efficiency: TPO roofing membranes are available in light colors, which reflect solar heat and help reduce cooling costs by keeping the building's interior temperature stable. The reflective properties of TPO roofing contribute to energy efficiency and can help buildings achieve LEED certification or other green building standards.

3. Flexibility and Ease of Installation: TPO roofing membranes are lightweight and flexible, allowing for easy installation on a variety of roof substrates. They can be mechanically fastened, adhered, or heat-welded to create a seamless, watertight barrier. TPO roofing systems are typically installed in large, prefabricated sheets, which can reduce installation time and labor costs.

4. Environmentally Friendly: TPO roofing membranes are recyclable at the end of their lifespan, making them an environmentally friendly roofing option. Additionally, their energy-saving properties contribute to reduced carbon emissions and lower environmental impact over the life of the roof.

5. Low Maintenance: TPO roofing requires minimal maintenance compared to other roofing materials. Routine inspections and cleaning are recommended to remove debris and ensure optimal performance, but TPO membranes are resistant to mold, algae, and dirt buildup, reducing the need for frequent maintenance and repairs.

6. Cost-Effectiveness: TPO roofing systems offer excellent value for money, with competitive upfront costs and long-term savings on energy bills and maintenance expenses. Their durability and longevity contribute to a lower total cost of ownership over the life of the roof.


Overall, TPO roofing is a versatile and reliable option for commercial buildings, offering a combination of durability, energy efficiency, and cost-effectiveness. It's essential to work with a qualified roofing contractor experienced in TPO installation to ensure proper design, installation, and maintenance of the roofing system.

Flat roof installation involves several key steps to ensure a durable and watertight roofing system. Here's an overview of the typical process:


1. Preparation and Planning: The first step in flat roof installation is thorough preparation and planning. This includes assessing the structural integrity of the existing roof deck, determining the appropriate materials and specifications for the new roof, and obtaining any necessary permits or approvals.

2. Removal of Existing Roofing: If there is an existing roof in place, it needs to be removed to create a clean and stable substrate for the new flat roof. This may involve stripping away old roofing materials such as shingles, tar, or gravel, and inspecting the roof deck for any damage or deterioration that needs to be repaired.

3. Repair and Replacement of Substrate: Any damaged or deteriorated sections of the roof deck are repaired or replaced to ensure a solid foundation for the new roofing system. This may involve replacing rotted wood, reinforcing weak areas, or adding additional insulation as needed.

4. Installation of Vapor Barrier and Insulation: A vapor barrier is installed over the roof deck to prevent moisture from penetrating into the building's interior. Insulation is then added to improve energy efficiency and provide thermal protection. The type and thickness of

insulation used will depend on factors such as climate, building codes, and energy efficiency requirements.

5. Installation of Roofing Membrane: The primary waterproofing layer of the flat roof is typically a single-ply membrane, such as EPDM (ethylene propylene diene terpolymer), TPO (thermoplastic polyolefin), or PVC (polyvinyl chloride). The membrane is rolled out and adhered or mechanically fastened to the roof deck, creating a seamless and watertight barrier.

6. Flashing and Edge Detailing: Flashing is installed around roof penetrations, such as vents, pipes, and HVAC units, as well as along roof edges and parapet walls, to prevent water intrusion at vulnerable points. Proper detailing and sealing of flashing are essential for maintaining the integrity of the flat roof system.

7. Final Inspection and Cleanup: Once the installation is complete, a final inspection is conducted to ensure that the flat roof meets quality standards and manufacturer specifications. Any debris or leftover materials are removed from the site, leaving the area clean and ready for use.


Flat roof installation requires expertise and attention to detail to ensure a long-lasting and reliable roofing system. It's essential to work with a reputable roofing contractor experienced in flat roof installations to ensure proper design, installation, and maintenance of the roofing system.
