Winter Care & Maintenance

These buildings are not industrial grade shelters and, as such, some caution must be exercised under some winter storm conditions….

Please see the WINTER CARE  page in our installation guide for additional information. We also have a Winter Care FAQ page with articles we have posted on this topic

Our structures are designed in a gothic shape with a slippery cover to be lightweight and snow resistant. This encourages the snow to slide off quickly.
This is not an industrial high snow load building. We do our best to always point out applications where the capacity of the structure is being compromised. Extra hoops or thicker steel are an economical way to increase wind and snow load capacity. We take pride in the sturdy shelters we manufacture and supply, but must point out that we cannot warranty against weather conditions.

Snow removal, when occasionally required, is a simple task. Uneven snow loading is deceiving, since the total weight is not a problem but the lateral force can cause the hoops to distort.It is rare to have any significant snow build up on the roofs; however,

DO NOT GO INSIDE A BUILDING WHERE THERE HAS BEEN OBVIOUS STRESS!

Be aware of these scenarios where excessive snow build up is possible and damage could follow:
A wet snowfall followed by dropping temperatures
A building 90° to the prevailing wind (drifts could form on the backside of the building)
A building attached to and situated downwind of a taller building (significant drifting)

A building 90° to another building that has a higher roof, could cause a surge in snow weight when the snow on the upper roof slides off.

Preventative measures for excessive snow build up (where possible):

Build structures inline with the prevailing wind
Build structures level from side to side to create uniform shedding
Do not attach your building to a larger existing building

Install a heat source to melt the snow

Economical additions to increase your structure’s snow resistance:

Install cable or tubular cross-ties at each pair of hoops, to create a triangle (when using cables there is no need to put them under tension)
Place wooden or metal support posts under the ridge. These can be suspended from the ridge with no more than ½” ground clearance. This will provide support as soon as there is load and structure movement will not dislodge your supports.

Use closer hoop spacing for the first 12’ section away from another bigger building

Pointers for removing snow:

NEVER remove all the snow from one side and then the other
Remove the snow off the top of your building before using a machine (snow blower, etc) along the sides

Use a padded piece of 1×4 wood on a pole (create a “T” shape) as the best tool for gently bumping the inside of the cover

BEWARE of this sequence which creates a “worst case scenario”:

Freezing rain, followed by dropping temperatures, Lots of snow followed by rainfall. It is easy to triple the weight of the snow load in 30 minutes.

Properly Venting a Building

Properly venting a building is a critical consideration when planning your building.

Getting rid of the initial ground moisture, quickly, when you have erected your new shelter is something many people do not think of. Quality air changes for plants or animals is something that automatically comes to mind. Getting rid of moisture is equally as important for storing your valuables.

Vent4Since warm air holds moisture and warm air rises, it is important to have venting capacity as high as is possible.

Venting through the roof, with individual turbines or a continuous roof vent, is the most effective but also the most costly.

This is only really necessary when you are in a very protected spot and there is a real need to keep the temperature down in a long building.

vent3Most medium length buildings that have the ends facing into the prevailing winds, can be adequately vented with gable end peak vents.

  • Make sure that these openings are as big as possible and as high as possible.
  • It is also important to make sure your “windows” can withstand the winds in your area.

Our centre pivoting gable vent has filled this requirement very effectively.

  • With part of the window going in and part of it going out, the wind can never get hold of it.
  • With the top and bottom rope through a double pully on the ridge, it is easy to maintain precise control over the opening area

As with all the other considerations, please do not hesitate to contact us with your specific set of circumstances and challenges
