 Trustindex verifies that the original source of the review is Google. I called for an estimate for a new roof. The price they quoted was way below two other estimates I received. I was also told that it would take 1-2 days to complete. Everything Alter Phase Contracting Inc promised was delivered.  They gladly supplied me with their licensing and insurance information. The warranty is printed on my receipt. My entire new roof was done in one day!  They left the property spotless. The owner was courteous, professional and upfront about the project from beginning to end.  I would gladly recommend this company to anyone. I’m loving my new roof!
