Parapet Walls for Commercial Flat Roofs

Wondering why there is a wall around your flat roof? Understanding why parapet walls are installed around low-slope roofing systems will give you crucial insight to their function and necessity.

Parapet walls for low slope roofing systems

The professional roofers at New Image Roofing Atlanta assembled a comprehensive guide to parapet wall design, height, necessity, and waterproofing.

What is a Parapet Wall?

A parapet is a barrier that is an upward extension of a wall at the edge of a roof (seen in many flat roofing projects). This extension projects above the flat roof (can vary in height and width according to local building codes and its designed function). The word comes ultimately from the Italian parapetto.

Parapet Wall Design

A plain parapet wall is a simple vertical extension of the wall on the building’s outside. They are most common in commercial buildings without ornate decoration (it can be difficult to tell where parapet walls start looking from the building’s outside). They are generally more about functionality than design. Consider the following:

Purpose and Functionality – Parapet walls serve various functions for flat roofs, acting as aesthetic and functional elements. They provide a barrier that conceals rooftop equipment, helps prevent falls, and enhances the overall appearance of the building. Additionally, parapet walls are a crucial line of defense against water ingress, a common concern with flat roofs.

Parapet walls are used to hide rooftop equipment and machinery

Aesthetic Considerations – From a design perspective, parapet walls contribute significantly to the visual appeal of a building. Architects often use them to create a uniform and pleasing silhouette, giving the structure a more finished and polished look. Parapets also offer opportunities for architectural creativity, with options for different materials, textures, and decorative elements.

Parapet Wall Height

Parapet walls are installed on flat roofs for safety

Local building codes often determine how and when parapet walls should be constructed on commercial structures.

Building Codes and Safety – Determining parapet wall optimal height is a nuanced process that involves adherence to building codes and safety regulations. Building codes typically mandate minimum parapet heights to ensure occupant safety and prevent accidents. The International Building Code (IBC) and other regional codes provide guidelines on parapet wall heights based on factors like building occupancy, roof usage, and fire safety.

Wind Uplift Considerations – Parapet wall height is not solely about aesthetics and safety (it plays a crucial role in mitigating wind uplift forces). Tall parapets can act as a windbreak, reducing the impact of strong winds on the roof and preventing damage to roofing materials. Engineers must consider local wind patterns and calculate the appropriate parapet height to optimize wind resistance.

When Are Parapet Walls Necessary

Parapet walls are mainly found on flat roofs, extending a vertical wall at the side of a commercial, industrial, or residential structure past the roofline. Flat or low-slope roofing systems include:

Parapet walls are typically required when the roof must double as something like a terrace, balcony, facilities area, lounging area, or walkway, helping keep the area safe.

Parapet walls promote safety on walkable roofs

Roof Access and Safety – Parapet walls become essential when rooftop access is necessary for maintenance, service, or other activities. They provide a protective barrier, considerably reducing accidental fall risks. OSHA (Occupational Safety and Health Administration) regulations often require the presence of parapet walls or other protective measures when employees work on flat roofs.

Read more about OSHA’s fall protection system criteria at osha.gov/laws-regs/regulations/standardnumber/1926/1926.502

Water Management – In regions with heavy rainfall or potential for flooding, parapet walls play a crucial role in:

  • Managing water runoff
  • Preventing water from cascading off the roof’s edge
  • Reducing erosion and water damage to the building’s foundation and landscape

Properly designed parapets incorporate drainage systems to efficiently guide water away from the roof surface.

Concealing Rooftop Equipment – Flat roofs often house HVAC units, solar panels, and other equipment or activities necessary for building functionality. Parapet walls offer an effective solution for concealing these elements, maintaining a clean and uncluttered appearance while providing easy access for maintenance.

Waterproofing Parapet Walls

Parapet walls use flashing to prevent leaks

Like your roofing system, parapet walls must repel and shed water efficiently. Parapet walls that allow water infiltration will lead to costly structural damages.

Flashing and Sealants – Effective waterproofing is paramount for parapet wall longevity and performance.

  • Flashing (water-resistant material) is installed at the roof and parapet junction to create a watertight seal
  • Sealants are used to fill gaps and joints, preventing water infiltration

Cap Flashing – Cap flashing is an essential parapet waterproofing component (metal flashing installed at the parapet wall’s top, extending over the roof membrane). Cap flashing prevents water from seeping into the joint between the parapet and the roof, offering an additional protective layer against leaks.

Parapet walls use metal caps and flashing to prevent water infiltration

Proper Drainage – Adequate drainage prevents water buildup on flat roofs and parapet walls. Scuppers (openings in the parapet that allow water to drain) are commonly used with conductors, gutters, and downspouts to ensure efficient water management. Regular maintenance, including clearing debris from scuppers, is crucial for the effectiveness of the drainage system.

How Roofing Systems Drain Water

Avoid costly water damage from your roofing system’s inability to shed rainwater. Understanding how a roof sheds rainwater will help you determine what to install or repair to prevent leaks and costly water damages.

Roofing systems shed water using slope gravity gutters and downspouts

New Image Roofing Atlanta gathered information on how low-slope (flat) and steep-sloped roofing systems are engineered to shed rainwater.

Low-Slope Roofing System Water Drainage

Low-slope roofing systems, common in commercial and industrial buildings, present unique challenges when addressing water drainage. Unlike steep-slope roofs that allow water to naturally flow down and off the roof, low-slope roofs require a more intentional approach to prevent ponding while ensuring drainage.

Note: Low-slope roofing can be EPDM, TPO, PVC, or BUR systems.

Gravitational Flow and Slope Design

Successful water drainage on low-slope roofing systems relies in gravitational flow. While these roofs have a slight incline, it is not as steep as in residential roofing systems.

Low-slope roofs are designed to combat water accumulation challenges, with a subtle slope to guide water toward drainage points.

A roof’s slope is carefully calculated during the design phase, ensuring water flows efficiently toward designated areas where drains, scuppers, and gutters are placed strategically. This intentional slope is critical in preventing pooling water (ponding), as ponding leads to structural damage, leaks, and accelerated wear on the roofing material.

Roof Drains, Scuppers, and Gutters

Scuppers help low slope roofing systems shed water

Roof drains, scuppers, and gutters are the most common and cost-effective drainage solution for flat roofs. These components catch and direct rainwater as it rolls off the roof’s edge and divert the water into downspouts that dispense it at a safe distance from the foundation of the building. Consider the following:

  • Roof drains are essential components of low-slope roofing systems. These drains are typically installed at the lowest points of the roof to collect and funnel water away. They connect to a network of pipes that direct the water down and away from the building’s foundation.
  • Scuppers are openings along the edges of the roof’s parapet walls that allow water to drain into a downspout or directly off the roof. They act as overflow channels during heavy rainfall or when debris blocks primary drainage points.
  • Gutters are crucial in low-slope roofing systems as they channel water from the roof’s surface to downspouts. Regular maintenance (like keeping gutters clear of debris) is fundamental in preventing water blockages.

Low slope roofing systems shed water using drains

Note: Drains running through a building or structure (internal drains) are serviced by a plumber when they experience blockages.

Residential Shingle Roofing Systems

Roofing systems shed water using the roof slope and gravity

Residential shingle roofing systems with steeper slopes leverage gravity and the roofing materials’ natural properties to channel water efficiently. From asphalt to metal shingles, these systems shed water swiftly, preventing leaks and protecting the underlying structure.

Roof Slope and Gravity

The steep slope of residential shingle roofing systems is fundamental in their ability to shed water effectively. Gravity plays a significant role, pulling water downward and away from the roof’s surface. The slope’s angle, often significantly steeper than low-slope roofs, facilitates quick and efficient drainage.

The roof pitch is carefully calculated during the design phase to ensure optimal water shedding. While the primary purpose of this slope is to encourage water runoff, it naturally contributes to the structure’s aesthetic appeal, influencing its architectural style.

Overlapping Shingles and Surface Tension

Roofing systems shed water using overlapping shingles

The materials used in residential shingle roofing systems are selected for their durability and ability to shed water. These shingles overlap, creating a seamless barrier that prevents water from infiltrating the roof.

Surface tension, the cohesive property of water molecules, aids in shedding water. As rainwater flows down the roof, it adheres to the shingle surface. The overlapping design encourages the water to travel downward, preventing it from seeping between the shingles and compromising the roof’s integrity.

Note: Exposed nails may sometimes provide additional reinforcement. When said nails are not sealed properly, they may begin to back out, allowing water infiltration and costly damages.

Eaves, Flashing, Drip Edges, Gutters, and Downspouts

Collecting rain water and carrying it away from your home’s walls and foundation is the roof’s drainage system (eaves, flashing, drip edges, gutters, and downspouts). This system prevents soil erosion and foundation damage. Consider the following sloped roof drainage components:

Eaves – Eaves (the roof’s edges that overhang the exterior walls), play a crucial role in water drainage. They provide additional protection by preventing water from running down the walls and causing severe damage. Eaves also contribute to the roof’s aesthetic appeal, defining its silhouette.

Eaves at the edge of a roofing system help it shed water

Flashing – Flashing (typically metal) is strategically installed in vulnerable areas like roof valleys, chimneys, vents, and other penetrations. Flashing acts as a water-resistant barrier, directing water away from these critical points and preventing leaks.

Roofing system flashing helps it shed water

Drip Edges – Drip edges, installed along the outer edges of the roof, guide water into the gutters and away from the fascia. They protect the underlying structure from water damage and help prevent issues like wood rot.

Drip edges shed water off the roof away from the structure

Gutter Systems – Gutters and downspouts play a vital role in roofing systems by channeling water from the roof and away from the foundation. Regular maintenance (including keeping gutters clear of debris) is fundamental to prevent blockages that interrupt water flow.

Roofing systems shed water using gutters and downspouts

Note: Gutters and downspouts must be properly sized to accommodate water runoff volume. If a structure’s gutters are too small, they overflow when heavy rain falls.

Tip: A maintenance plan can help detect and correct drainage issues in their infancy before developing into costly damages.

Roof Drainage Systems

In this article, you discovered how roofing systems drain rainwater and the components that efficiently divert the runoff from the structure, preventing water damage.

Knowing how a roofing system sheds rainwater will enable you to make informed decisions when installing, maintaining, or repairing your residential or commercial roofing system.

Ignoring your roof’s drainage system can lead to leaks, costly water damages, and challenging structural repairs.
