Video: Norm explains the situations where you would need to remove snow from a Greenhouse or Storage Building and how to do it safely
We are once again in a part of the season where freezing rain is a potential threat.
The freezing rain itself is not the threat, even if there is a lot, since at a certain point, if there is enough ice, it would become self supporting
Where the potential risk comes, if the temperature would fall and the ice would really freeze to the cover, snow would not be able to slide off the structure.
To prevent this from happening, take a few minutes to gently bump the cover to remove the ice.
The critical thing to remember when bumping the cover is to ALWAYS start at the top and work down. This way the lower ice will “protect” the cover when the higher ice is sliding down.
The sooner this process is done, the smaller the job will actually be.
But PLEASE do not go in a compromised structure, you are more important
We have a unique structure that we have started offering more often. It is a round dome structure, with our standard hoops around a circular ridge piece. We have taken to calling this our “Canadian Igloo” Structure. Plastic is put on in separate pieces so it’s not for the new greenhouse assembler. We have them being used for everything from seminar areas to storage, whatever you would like a unique application for!
Please see our Igloo Round Application Page for more info, and call for your custom quote and with any additional questions you may have.
Winter Storm & Your Structures
Many areas have been hit with freezing rain today and even though it has generally not been enough to warrant concern for the structures, it is a good time to recap some common things when dealing with ice on buildings.
It is important to note that the ice in itself is not an issue, even a very thick layer actually has enough strength to become self supporting. There are two potential problems though:
- If the ice stays on the building, it usually has a rough enough texture that subsequent snow will not likely slide off. This scenario lead to major problems in previous winters when we had freezing rain, followed by a dump of snow and then we had rain. This can triple the weight on a building in very short order.
- The other potential problem happens when you are attempting to remove the ice from the building. If the ice layer is not too significant you can gently bump the cover from the inside. ALWAYS start bumping the cover from the top. This way ice will slide over ice. Starting from the bottom creates a potential where the ice sliding down will fall back against the building and slash the cover. NEVER do all of one side and then the other. Work both sides simultaneously.
If there is the slightest doubt in your mind about the amount of weight on the building, bump the cover from the outside using something with a long handle.
If in doubt please don’t hesitate to ask.
With the upcoming storms in both Ontario and the east coast forecasted, we wanted to remind everyone: it’s okay, and even preferred that the buildings have some snow around them.
This prevents the wind from getting under them and it also means that the height above the ground is less. This significantly decreases the aerodynamic lift.
As we’ve stated in our winter care articles and in the installation guide, there are things you can do to prepare your building to withstand the storms as best as possible. Taking extra steps during the ‘worst case scenario’ situations can often make all the difference and help your building stay standing.
Please don’t hesitate to contact us if you have any questions about any of these situations. Good luck and stay warm!
