Many commercial roofs are flat, making a roof drainage system necessary as standing water can cause severe damage. Exploring different types of commercial roof drains helps determine the best option for your business. At United Contracting & Roofing LLC in Greenville, SC, we emphasize the importance of choosing the right drainage system to maintain your roof’s integrity.
The Importance of Drain Systems
Understanding why a drainage system is necessary is crucial. Drains channel water off the roof, protecting against both exterior and interior damage. Without a proper drain system, water can collect on the roof, break down the barrier membrane, and eventually seep inside, leading to costly repairs. Leaks can cause minor issues like water stains and mold or significant problems like product damage and operational setbacks.
The Two Main Forms of Drain Systems
When choosing a drainage system, consider these two main options:
- Gravity: This system uses gravity to allow water to flow off the roof. Differently sloped segments all flow to one interior drain, working in tandem to carry water off the roof.
- Siphonic: This option does not rely on gravity. The drain’s opening is fitted with a part that prevents air from entering, creating lower atmospheric pressure inside the drain. This pressure difference sucks water in, allowing it to move freely without a graded decline.
The Four Types of Drain Systems
Four types of commercial roof drains work well with flat roofs:
- Gutters: Common in residential areas but also used in commercial buildings, gutters are installed on the roof’s edges to collect water and pass it into a downspout. Gutters must work with a slightly graded roof to function effectively and must be kept free of debris.
- Downspouts: Similar to gutters, downspouts work with a roof scupper to carry water to the ground. This drainage pipe prevents water from touching the building, protecting against mold, moss, and mildew.
- Scuppers: Scuppers are channels or openings in the roof’s sidewalls, allowing water to flow off the roof. They can connect with gutters or downspouts for efficient water removal.
- Internal Drains: Internal drains are placed under the roof’s surface, typically where water collects the most. These drains are often used with other systems, such as scuppers, to ensure proper drainage.
Choosing the Right Drainage System
Selecting a roof drainage system depends on your roof type and the advice of roofing experts. Knowing your options can make the process less confusing. Commercial roof drains help protect your roof from water damage by ensuring water flows off rather than pooling. Work with a roofing expert to decide which drain option best meets your building’s needs.
