Commercial flat roofs are a popular choice for many businesses due to their cost-effectiveness, ease of installation, and the additional space they provide for equipment like HVAC systems. However, one of the key challenges with flat roofs is effective drainage. Without a proper drainage system, water can pool on the roof, leading to leaks, structural damage, and other costly issues. At Motor City Roofers in Detroit, Michigan, we understand the importance of a well-designed drainage system for commercial flat roofs. Here’s a comprehensive look at how these systems work and why they are crucial.

The Basics of Flat Roof Drainage
Unlike pitched roofs, flat roofs have a slight slope (usually between 1/8 to 1/4 inch per foot) to facilitate water runoff. This subtle slope directs water toward the drainage points, preventing standing water which can cause damage. There are several types of drainage systems used for flat roofs, each with its own design and functionality.

1. Internal Drains
Internal drains are a common choice for commercial flat roofs. They consist of a series of drain pipes installed beneath the roof surface, connected to the building’s plumbing system. These drains are typically positioned at the lowest points of the roof to collect water and funnel it away.
​
Components of Internal Drains:
Drains:
Placed at strategic points on the roof, usually in the center or at low spots where water tends to collect.

• Drain Pipes: These pipes run vertically down through the building, connecting the roof drains to the ground-level drainage system.
• Strainers: Mesh covers placed over the drain openings to prevent debris from clogging the pipes.

Advantages of Internal Drains:

• Aesthetically Pleasing: The pipes are concealed within the building structure, maintaining the roof’s appearance.
• Effective Water Removal: Can handle large volumes of water efficiently, making them suitable for large commercial roofs.
• Prevents Ice Damming: In cold climates like Detroit, internal drains help prevent ice damming as the water is directed inside the building where it is warmer.

2. ScuppersScuppers are openings in the perimeter walls of the roof that allow water to drain off the edge. They are usually used in combination with downspouts to direct water away from the building’s foundation.
Components of Scuppers:

• Scupper Openings: Located at the roof’s edge, these openings allow water to flow off the roof.
• Downspouts: Vertical pipes attached to the scuppers, guiding water down to the ground level and away from the building.

Advantages of Scuppers:

• Cost-Effective: Generally less expensive to install than internal drains.
• Low Maintenance: Easier to clean and maintain as they are accessible from the roof’s edge.
• Prevents Water Accumulation: Effectively prevents water from pooling on the roof, reducing the risk of leaks.

3. Gutters and DownspoutsGutters are channels installed along the roof edges to collect and direct water to downspouts, which then transport it to the ground.
Components of Gutters and Downspouts:

• Gutters: Horizontal channels installed along the roof edge to collect water runoff.
• Downspouts: Vertical pipes that carry water from the gutters to the ground level.

Advantages of Gutters and Downspouts:

• Versatile: Suitable for a variety of roof sizes and types.
• Easy Installation: Simple to install and maintain.
• Prevents Foundation Damage: Directs water away from the building’s foundation, preventing erosion and structural issues.

4. Siphonic Roof Drainage SystemsSiphonic drainage systems are advanced solutions that use the principles of siphonic action to remove water from the roof quickly and efficiently. These systems create a full-bore flow in the pipes, which increases the drainage capacity without the need for a slope.
Components of Siphonic Drainage Systems:

• Siphonic Roof Drains: Specially designed drains that create a siphon effect, allowing water to be drawn off the roof at a higher rate.
• Non-Sloping Pipes: Unlike traditional drainage systems, siphonic systems use horizontal pipes without the need for a slope.
• Air Baffle Devices: These prevent air from entering the drainage system, ensuring the siphonic effect is maintained.

Advantages of Siphonic Drainage Systems:

• High Efficiency: Can handle large volumes of water quickly, making them ideal for large commercial roofs.
• Space-Saving: Requires fewer pipes and less space than traditional drainage systems.
• Cost-Effective: Reduces the need for extensive piping and structural modifications, lowering overall installation costs.

​
Importance of Proper Drainage MaintenanceRegardless of the type of drainage system installed, regular maintenance is crucial to ensure its effectiveness. Clogged drains, scuppers, or gutters can lead to water pooling, which can cause severe damage to the roof and the building structure.
Maintenance Tips:

• Regular Inspections: Schedule routine inspections to check for blockages, damage, or signs of wear in the drainage system.
• Debris Removal: Keep the roof and drainage components clear of leaves, twigs, and other debris that can cause clogs.
• Seasonal Maintenance: Pay extra attention during fall and winter when debris accumulation and freezing temperatures can impact drainage performance.
• Professional Cleaning: Consider hiring professional services like Motor City Roofers to perform thorough cleanings and inspections, ensuring your drainage system remains in optimal condition.  A well-functioning drainage system is essential for maintaining the integrity and longevity of a commercial flat roof. By understanding the different types of drainage systems—internal drains, scuppers, gutters and downspouts, and siphonic drainage systems—you can make informed decisions about what best suits your building’s needs.
