Roofs may need to be functional in all weather; but when installing or inspecting a roof in cold weather, extra care must be taken. Versico has put together a list of cold weather installation and safety tips to make sure you put down the best roof possible, while staying safe!
- Dress properly for the weather conditions
- Be aware of skylight and hatch openings that may be covered by snow. Check the roof plans for the locations of any penetrations.
- Be aware of your position on the roof with respect to perimeters and other roof levels.
- Check for icy surfaces that may be hidden by snow, and check for iced rungs on ladders.
- In colder weather, white membranes reflect heat and can promote slippery conditions due to ice build-up that may not be visible.
- VersiGard EPDM - Use non-folded sheets for cold weather installation. EPDM flashing products may require additional warming from a heat gun in cold weather.
- VersiWeld TPO & VersiFlex PVC - TPO and PVC membranes and walkway rolls must be allowed to relax after they are unrolled and before installation. Also, welding techniques must be adjusted for cold weather application.
- Low-VOC Bonding Adhesives and Primers - Store these products between 60°F - 80°F, and if outside temperatures are going to be less than 40°F, a heated enclosure or hot box is recommended for jobsite storage. TPO and EPDM membranes should be relaxed for 30 minutes or more before applying adhesives in cold weather.
- CAV-GRIP 3V - This adhesive can be applied in temperatures of 25°F or above, but the cylinder must be kept above 60°F for the product to spray properly.
- Flexible DASH - Store this product between 60°F - 80°F and return to 70°F before use. Flexible DASH can be applied in temperatures of 25°F or above, but if temperatures are below 60°F, hot boxes or heated blankets are recommended.
