If you are going to have anything done to your roof, this is the company to call!  Palo Alto Roofing did a great job fixing a leak in our roof back and 2010 and after this last storm, we noticed another leak.  Super professional company with great warranties and fully insured, so we called John Font (the owner) on a Saturday and he came in less than an hour to look at our roof.  The leak was unrelated to our previous problem and get this…he fixed it for us at no charge!  This guy knows his stuff and explained the leak was due to something about a clogged gutter and a sidewall (the way he explained it was way more technical and informative… all I really heard was, “I found the problem and went ahead and fixed it, no charge).  Dependable, professional and highly recommended!
