According to the Alberta Urban Municipalities Association (AUMA), the average of the heaviest snowfall that Alberta last winter was cited as a factor contributing to failure of the roof over two dozen buildings. Some examples of high-level include: partial roof collapse of the oldest bullring in the city of Sylvan Lake, shortly after midnight January 20, 2014; and the collapse of the roof of the curling club in the town of Drayton Valley in the afternoon of January 24, 2014 (several people were in the building at the time). The same pattern was reported in Saskatchewan communities, with also cited winds
time change can impact any business. extreme cold, high winds, heavy snow and ice can immobilize a building, installation or zone leading to physical damage and disruption of business operations. Winter storms can also cause power outages, floods, closed transport networks and blocked roads. . geographic locations that do not generally experience such extreme weather now see these effects more frequently
Examples of risks associated with the winter include:
• Heavy snowfall or accumulation of ice on the roofs of buildings, outdoor equipment, power lines, leading to a potential collapse.
• low temperatures causing the freezing water filled pipes, including treatment and sprinkler systems.
• blocked roof drainage systems and gutters leading to save water and subsequent penetration into buildings.
• Temporary heaters creating potential fire hazards
• failure of the heating system leading to low temperatures in the facilities
Here are some tips to help you minimize the damage that can occur from winter: ..
• Arrange for snow removal on roads, roofs, doors, gates, outdoor valves, fire hydrants, etc. It is recommended that anyone you hire for this task is carried out and / or related and have references or experience with these specific operations.
• Identify and consider removing all the large trees or limbs that could fall because of snow or loading ice and damage buildings, outdoor equipment, power lines, etc.
• Ensuring all buildings are "tight schedule." Close all windows, doors, vents, etc. and seal all openings in the exterior walls, ceilings, roofs, etc.
• indoor temperature for all heated buildings must be constantly maintained above freezing or at least 4 ° C
• all unoccupied or vacant buildings should be checked every 72-96 hours and maintained a journal each inspection.
• Assess the snow load capacity of your roof. Be prepared to remove the excess snow accumulation during storms if necessary. Accumulations below are for guidance only, as ice or wet snow may cause a heavier load:
- For commercial buildings, condominiums or apartment buildings, the code of the Alberta building states that the withdrawal should be considered after 20in or 50cm of snow accumulation.
- for a typical house roof, the snow removal should occur once 16in or 40cm accumulated.
• Inspect roofs for all structural problems or obvious maintenance than repair if necessary: ...
- Cracked or curved beams, joists or columns
- rusted or deteriorated decking
- Cracked or damaged roof coverings
- all areas where water is pooling or accumulation.
• Check all roof drains, drainage pipes and gutters are free of debris and have adequate drainage of water.
• Inspect all heating systems (heating and boilers, furnaces, ovens, heaters, etc.) to ensure proper operation.
• Inspect all processes, water, fuel, steam, tanks, etc. lines subject to freezing for good insulation. Check these systems for cracking, deformation or leakage.
• Empty any equipment charged with water or pipes located in unheated areas or unoccupied / vacant buildings.
