My roof is appox two years old. I have had Gandy out here twice to repair the vallys of my roof due to birds geeting into tthe attic. I again have a problem with a vibration when evey the wind is high . It sounds like the front of the house is going to come off. How do I get this problem resolved?Also what about my 30 year warranty on workmanship and shingles?
