had our roof done with them in in 2005.with in 3 weeks had a leak in the roof. then in 2011 roof is leaking again . will not return our phone calls in this matter. will not ever use them again.

Will keep you posted, on going problem, whole roof tear off, insurance adjuster recently found roof not completely torn off, no ice and water shield installed, and Williams Exterior are stalling on making good their workmanship. Roof done in 2004, but work supposed to be guaranteed for 10 years, and shingles for 30. Work not done according to code.
