I really appreciate Cornell and his team. They are dependable and trustworthy.  I have recommended them to several people, and I used them again recently for a roof leak that I've had "repaired" twice by contractors I picked from Angie's List.  
Turns out, the problem was not popped nails, it needed a bit more TLC and it was repaired promptly. 

It is a relief to know that there is a group I can call that will help me out when I need it.  Do not hesitate to give them a try.
