When looking for good roofers in your area, contact your local Chamber of Commerce.
They usually have a list of recommended companies you can access as a start to your research.

Ask your roofing contractor to include regular maintainance inside of your contract of having it replaced.

When it rains, check your attic for leaks.
Not every leak will make it down to your ceilings, so there is no harm in heading upstairs to check out what is going on.
