Your Post Woodworking, Inc. building has a 20-Year Limited Warranty for structural integrity. This warranty does not include doors and windows (for obvious reasons). The roof shingles have a 20-Year Warranty against leakage. Natural disasters, damage by accident or neglect are excluded. With proper maintenance we expect your building to last a full lifetime and more. We expect that when we have been gone a hundred years many of our buildings will still be standing all over the United States. Post Woodworking, Inc., gives no other warranty expressed or implied, either oral or written.
