At Watertite Roofing - Specialists in Flat Roofing Since 1976, we've been receiving an influx of calls about apparent flat roof leaks due to the recent extreme cold. However, upon inspection, we often find that the roof itself isn’t the issue, but rather the problem stems from frozen drains, eavestroughs, or scupper drains.
How Extreme Cold Causes Leaks
With sub-zero temperatures, water in drain pipes and eavestroughs can freeze, blocking proper drainage. This creates a chain reaction:
- Drain pipes freeze, trapping water inside.
- As the ice expands, it puts pressure back up the pipe, forcing water to seep into the roofing system through joints or seams.
- If the pressure builds too much, it can cause pipes to crack or burst, leading to major leaks.
Similarly, when eavestroughs fill with ice, a phenomenon called ice damming occurs. This forces water to back up along the roofline and leak into the building at the drip edge.
How to Prevent Frozen Drain Pipes & Eavestroughs
The best way to stop these cold-weather leaks is by preventing ice buildup in your drainage system. Here’s how:
1. Install Heated Cables
One of the most effective solutions is to have an electrician install heating cables along your pipes and eavestroughs. These cables melt ice buildup, allowing water to flow freely.
2. Use a Thermostat-Controlled System
An electrician can wire the heating system to a thermostat, so it only activates when temperatures drop below freezing. This makes the system more energy-efficient and saves you money.
3. DIY Heating Cable Kits
Many hardware retailers sell DIY heating cable kits, which homeowners can install themselves. However, professional installation is recommended for optimal performance and safety.
