February Features! *Winter and Your Structures*

We have a number of resources on our website to help you with taking care of our structure over winter. We have compiled a list of “Greatest Hits” below, that you can review at your leisure and please don’t hesitate to contact us with any questions if you are unsure or can’t find what you’re looking for. We are always happy to help.

The best place to start is the Winter Care Pages in our instruction manual.

We also have: Winter FAQs

Winter Care & Maintenance
Important notes for various situations
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….

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

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….

Retightening a Loose Structure Cover
Re-tightening a cover does not have to be done in one day. Taking a short cut will leave you with more wrinkles. Areas with wrinkles will flutter more and cause stress points.
This will also cause the cover to deteriorate quicker……

Temporary Fix for a Loose Cover
There are a number of instances where a cover will need to be installed in less than ideal conditions. This can be either be on a windy day or in the cold (-10C or worse) and the job simply can not wait.

Season Extension: Hanley Caterpillar Tunnels
The real lure of these buildings is their low cost and simplicity to move. Generally the area is prepared in advance and then the tunnel is moved over the area when the planting is to be done…..

Happy Valentine’s Day and Family Day! We hope you and your family are staying warm, and getting excited for the upcoming spring and growing season! We look forward to working with you on your projects in 2021!

Winter Weather Reminders

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

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.

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

Important Winter Care Articles

We have published a few articles regarding winter care and maintenance, and suggest anyone who has purchased a structure from us to review them to make sure your shelter is safe over this winter. As always, we are available for anything you are wondering or concerned about. We would be happy to help.
