SierraWest-James Builder started my roof replacement in March 2015. I am still waiting for them to return to repair leaks. Several calls have been place with promises that they will be here to fix things and there has been no one on my roof since March. I cannot get anyone to give me a statement of work completed.
They are alot of talk and no work.
