Alfredo is responsive, punctual, professional, and he and his father do excellent work. They have repaired leaks that other roofers were unable to properly repair. He explains whatever issues there are and then very clearly tells you what the repair will involve. His prices are absolutely reasonable and he never adds on "unexpected" charges. The work is done efficiently and always finishes within the expected time frame. He gives an excellent warranty on their work and always sends before and after pictures. I highly recommend Alfredo and his crew without hesitation.
