The shingles are not included with Do It Yourself shed kits to allow the homeowner to customize the shed. Some areas require certain shingle types or colors for permitting or HOA approval. Also some customers want their shingles to match their home. Be eliminating them from the kit, this lowers the cost of the kit and allows that customization. If you have missing parts or warped wood please contact us here at customer service. The toll free number is 800-221-1849. We will be happy to get replacements shipped out to you or reimburse you for parts you had to purchase. I do apologize.
