Retightening a Loose Cover

Previously we outlined how to do a temporary fix for loose cover. This should not be left for an extended period. Re-tightening a cover does not have to be done in one day.

  • The job MUST split into two parts lengthwise.
  • The cover must be pulled lengthwise BEFORE it is pulled from side to side.
  • Make sure you do the tightening process on a calm, warm day.
  • You should do the end which looks the worst first.
  • This job will require taking ALL of the cover fasteners out.

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.

When you are tightening the cover, you should always pull 90 degrees to the wrinkle.

This means that after you have secured at the peak,
most often you will be pulling diagonally to the corner.

Once you have done one end/half and the wind is still down, you can start loosing the fasteners on the other end and repeat the process until complete.

Please don’t hesitate to contact us if you have any questions.

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.

This will almost invariably lead to a situation where the cover will need to be re-tightened on a warmer and/or calmer day. Doing this temporary fix will get you an extra month of time that you can wait until it warms up and you can do a better job retightening the loose cover.

The lifespan of a cover can very quickly be reduced if it is repeatedly flapping in the hard wind. A very effective, temporary fix to give you more time to do the job right, is to put ropes or straps over the building (as in the photos below)

A 1” or 2” wide seat belt type material is ideal but likely you will need to settle for a soft, marine grade rope instead. Using nylon rope is almost worse then using nothing because of the abrasion factor.

The idea is to put a strap or rope between pairs of hoops every 12’ to 16’ and pull as tight as you can. Use nails or eye bolts on your base as the spot for securing the ropes or straps.

If your cover is especially loose, it is best to install each of the ropes or straps snugly first. Then go back and tighten them as tight as you can. This will prevent you from pulling too much in one spot.

Please don’t hesitate to call if you have any questions about this technique. We would be happy to help clarify anything you need, to keep your building secure.

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.

Please call us if you have any questions about any of this. Thank you

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.
