We just had our roof replaced. We replaced it a few years ahead of schedule, but it had some wear on it that didn't look right. 

When the roofers removed the old roof, they found the start of rot along one side. No deep damage. Easy to repair at this stage. The roofer did so at no additional cost. 

The Husband and I are drawing up a list of big ticket items that we want to pay off before we make any big career changes. Replacing the roof early was one such expense. And a timely one as well.
