The cost effectiveness and functionality of flat roofs make them a popular choice in the world of commercial roofing. However, the very feature that defines them also presents a unique challenge: drainage. Proper drainage is not just a recommendation for flat roofs, but a necessity.
At Showalter Roofing, we understand how important drainage is when it comes to the longevity and performance of your roof. Read on to learn why roof drains are so important and how you can ensure your roofing system remains robust and efficient.
Why Flat Roof Drainage Matters
1. Prevents Water Accumulation: The primary role of effective drainage is to prevent standing water from accumulating on your roof. Water that stands for more than 48 hours can seep into the roofing membrane, weakening it. It can also lead to leaks, mold growth, and structural damage, all of which can be costly to fix.
2. Ensures Building Safety: Pooled water on a roof can add significant weight, putting stress on the building’s structure. In extreme cases, this can lead to roof collapse, posing a safety hazard to occupants.
3. Improves Energy Efficiency: Water on a flat roof can affect the roof’s thermal performance. Good drainage ensures the roof remains insulated. This in turn helps with regulating the building’s temperature and reducing energy costs.
Optimizing Your Roof Drainage System
Design and Installation
Proper drainage starts with good design. Proper installation means installing your roof with a slight pitch towards drainage points to promote water runoff. It also involves choosing the right type of drainage system for your building.
Regular Maintenance
Even the best-designed drainage systems can fail if not cared for. Regular inspections can identify and address issues like blockages or damage that can impede water flow. Ensuring your drainage paths are clear is especially important following severe weather.
Drainage Solutions
There are several drainage systems suitable for flat roofs, including interior drains, scuppers, and gutters. Interior drains, hidden within the building’s structure, are great for large roofs. Scuppers, which are openings on the side of the roof, are good for quickly directing water away from the building, preventing water damage. Gutters, meanwhile, are a common choice for collecting water and directing it away from the building’s foundation.
We can assess your commercial flat roofing needs to determine which type of drainage system best suits your property.
