Flat & Low-Slope Roofing

Flat and low-slope roofing systems are commonly used for commercial buildings, offering a functional and cost-effective solution for large roof areas.

What is Flat & Low-Slope Roofing?

Flat and low-slope roofing refers to roofing systems that have a slope of 2:12 or less, meaning the roof’s angle is very shallow or nearly horizontal. These roofing systems are typically constructed with single-ply membranes, built-up roofing (BUR), modified bitumen, or EPDM (ethylene propylene diene monomer) rubber roofing. Unlike sloped roofing systems, which shed water naturally, flat roofs require additional methods, such as drainage systems or tapered insulation, to channel water off the surface and prevent pooling or leaks.

Benefits of Flat & Low-Slope Roofing

Known for its sleek appearance and long lifespan, metal roofing is an ideal option for those seeking superior protection for their home.

Cost-Effective:

Flat and low-slope roofs are typically more affordable to install than steep-slope roofing systems due to the simpler design and the ease of access for workers. The materials used are generally less expensive and require fewer resources to construct.

Space Efficiency:

The flat surface of these roofs offers the opportunity to utilize rooftop space for HVAC systems, solar panels, or even green roofs, making them a practical choice for commercial buildings that need additional space or want to improve energy efficiency.

Durability:

These roofs are designed to withstand heavy weather conditions, including rain, wind, and snow, with the right materials. Modern flat roofing systems, like EPDM or TPO, are highly durable and resistant to UV rays, which prolongs their lifespan and reduces maintenance costs.

Ideal Applications & Climate Suitability

Flat and low-slope roofs are most commonly used on commercial buildings due to their practicality and ease of installation. They are ideal for structures such as office buildings, shopping centers, warehouses, and industrial facilities.

  • Climate Suitability: Flat and low-slope roofing systems are versatile and can perform well in a variety of climates, but their performance largely depends on the materials chosen. In hot climates, reflective roofs can help reduce energy costs by minimizing heat absorption. In colder climates, flat roofs are effective at shedding snow, but they may require additional insulation to prevent ice damming and water pooling.

  • Water Drainage: Since flat roofs have minimal slope, proper drainage systems are crucial to prevent water buildup and leaks. The roof should be designed with a slight pitch or tapered insulation to ensure water flows toward the drains. In areas with heavy rainfall, internal drain systems may be used to direct water away from the roof surface.

Maintenance and Care for Flat & Low-Slope Roofing

Proper maintenance is essential to ensure the longevity and performance of flat and low-slope roofing systems. Although these roofs require less upkeep than other types, periodic attention is necessary to prevent issues and extend their lifespan:

Regular Inspections:

Flat and low-slope roofs should be inspected at least once a year or after major weather events. Check for cracks, punctures, or areas where the membrane has become loose. This helps identify problems early before they lead to leaks or other costly repairs.

Maintaining Roof Coatings:

Many flat roofs have reflective coatings designed to protect the membrane and improve energy efficiency. Over time, these coatings may degrade or wear off. Recoating the roof as needed can help extend its lifespan and improve performance.

Checking for Leaks:

Flat roofs are more prone to water pooling, which can lead to leaks. Be proactive in checking for signs of water intrusion, particularly around seams, joints, and edges. Regularly check interior spaces for water stains or signs of moisture.
