This biggest problem with pole barns and buildings is their roofs leak.   Ask anyone who has owned one for very long and they will tell you the same thing.  Sooner than later, they leak! 
 To quote one of our competitors:

Then they proceed to provide information and prices based on leaky barn roof standards.
Oregon Pole Barns addresses this problem right up front by using products, certified engineered building plans and a leak proof roof system on all of our barns, and at a price other companies charge for roofs that will eventually leak.  Go immediately  to our questionnaire, fill it out and we will send you an information sheet about  our “forever roof system” and our custom made insulated wall wrap.
 
We will not be undersold and guarantee our prices for our “forever roof system” will compete head to head with our competitors or we will give you $1000 credit on our wall wrap system.
