Roof or Ruff/Rough?

I was born in California and moved to the great state of Washington before starting elementary school. Because I was born of non-native washingtonians I was not taught the local pronunciations. One of those being the pronunciation of the word roof. Native speakers pronounce this word quite differently (Rough or Ruff). No matter how you pronounce it the framers started assembling the different sections of the trusses to the roof today.
