Custom shed is the way to go..I thought I would take advantage of a shed that was built over winter..to take advantage of the savings..not a good thing. the ridge vent was missing along with the plate across the doorway... and from being stored in the field down back all the water run-off through that area the shed was twisted the side door still is not opening the way it should. the rear 4 x 4 was hanging when it was placed on the pad and others twisted. I reported the problems and the way they talked to me this was a normal thing.. and they were fighting with the township so they could get the storage problem taken care of down back. I will have a carpenter do the repairs and install the ridge vent.. You get what you pay for. PAY THE EXTRA..I still like the shed and will get all repairs done.
Sorry to hear about your problems with your building. Your building does come with a five year warranty. I hope we can do something to make these corrections so you will not have to hire a carpenter to do the repairs. We will have someone give you a call to make the corrections or replace your building.
