Mailbox doors can be difficult, since they will be operated daily for years, must be convienient for the mailman, and must be original in their own way. Mailboxes are relatively expensive because they usually take at least a full day, and often more than a half sheet of copper, currently at $100 per sheet. They will last indefinitly, and that is one of the things that is most important to me. This cedar mailbox has a copper roof, and these two materials are very long lasting. The copper roof will keep the wood dry, and everyone knows that a good roof will keep a building standing for a long time.
