Luckily, the greenhouse is covered under my house insurance and so I will have a replacement some time this year - I will most likely need to wait until at least June as the ground is too wet for that type of construction to take place.
I managed to get inside just a few days ago and I am happy to report that very little of the equipment and tables seem to be damaged although I'll need to wait until the snow is fully melted to get a proper idea.
With the heavy rains last week, and more coming, I had to tear some holes in the plastic to release some of the water or the weight may have led to more damage. But I want to save as much of the plastic as I can for salvage ... I'll use some to build cold frames and will give some to a friend to replace his own greenhouse plastic when needed.
It was a very unfortunate experience and it is frustrating not to have the greenhouse in working condition this spring, but it should work out OK in the long run - a newer structure that should be able to withstand the difficult winters we have now and then.
