Touching wood, my Shelter Logic has been my hay and carriage barn for several years now, standing up to Irene and a direct hit from Sandy. Recently a 40’ oak tree gave me a few new skylights, but even with that the damage was minimal and easily repairable.
A huge portion of my success is owed to the location, hidden in a stand of trees for a great windbreak (worked great for the wind for so many years, trees apparently needed to even things out a bit).
If its possible to move the location to someplace with a windbreak, I would. I don’t know of too many success stories with these types of structures when left out in the open. Even if you have a large truck or tractor or anything you can park along side it, will help.
Rather than using the 4 augers that came with the unit, I purchased 12 huge eyebolts, each nearly 3 foot long, pounded those into the ground with a sledgehammer and then used the strapping that came with the unit to batten down the structure.
The tent has excess length on the sides for a reason, back fill a foot of dirt along the length to keep the sides down from flapping.
Cutting a hole in the top of the “door” on either end has worked well for me allowing wind to travel through rather than pull it apart. Also was critical for keeping condensation from happening in the summer. It literally rained on my hay one summer from the inside. Talk about a sad shock.
Finally, I have heavy duty tarps spread over the top of the tent and tied off to logs that run the length of the structure. These are primarily to deflect small branches, but it really minimized the damage when the tree plunged through the roof and keeps the main tent from flapping.
When I went to repair my holes, I used waterproof Gorilla tape. I don’t like the tape made for fixing the tent, it peels up when its humid.
Main thing to see if you can do though is a windbreak of some kind. Anything will help.
