When the temperature begins to dip, welding roofing material takes on special challenges. Here are our tips to ensure a watertight weld in cold weather.
1. Go slow
Reducing your speed can result in a better weld in cold weather. The slower the speed the more time material has in contact with the hot air.
2. Turn it up
Increasing the tool’s temperature can help compensate for the lower temperature of the material and surrounding environment.
3. Don’t forget the wind
The wind on a roof can create a significant decrease in temperature. Make sure you account for this.
4. Test often
Make sure test welds are done often. Changes in cloud cover, wind, and time of day all affect temperature which could necessitate changing your tool’s settings. Make sure test welds are done on a flat, dry, and clean surface; do not weld directly on concrete, instead place a piece of plywood between the ground and material.
5. Cover up
Consider using a portable tent shelter to shield the area being welded from the outside environment.
The biggest key to successful cold weather welding is being aware of the changes in the environment and adjusting your tools accordingly. Check your welds often to make sure tool adjustments are working.
