Protecting your Business Property in Winter

Cold Air in Enclosed Spaces

• Inspect concealed spaces for gaps in wall materials; water pipes in these areas can freeze if unprotected.
• Keep these spaces warmed to at least 50° F or use certified heat tape

Sprinkler Systems and Related Equipment

• For wet-pipe systems, keep building temperatures at 50° F, including enclosing a riser equipped with a dry pipe valve.
• Dry pipe systems should be drained at the low point before the onset of cold weather.
• Service and inspect all hydrants, tanks, fire dept. connections and sprinkler system accessories before the onset of cold weather.

General Building Protection

• Inspect vacant properties or unoccupied areas of a building during cold weather to be sure heating systems are functioning correctly.
• Identify sources of cold air infiltration and repair leaks or seals.
• Inspect roofs to be sure they can withstand snow loads; remove snow from roofs if roof strength is in question.
• Keep gutters, downspouts, and roof drains clear to avoid clogging and freezing.

Preventing Ice Dams

• Increase insulation above ceilings inside the building.
• Consider the use of heating cables to prevent ice dams.
• Increase ventilation in attic spaces.
• Inspect roofs for evidence of standing water (mold, mildew, vegetation) that might indicate future problems, and contact a roofing contractor to address the situation.
• SAFELY remove snow with a roof rake or stiff-bristled broom when ice dams have been a problem (always follow OSHA guidelines for worker safety during roof work).

Responding to a Heat Loss Event

• Drain any equipment that contains water that could freeze if the temperature drops.
• Investigate sources of temporary heat to be prepared for low temperatures.
• Train security or maintenance/facility personnel on how to close automatic sprinkler valves if a leak or break should occur.

Taking the above steps and performing routine property maintenance can be vital to preventing property damage during winter and throughout the year.
