I called Dial One Roofing to replace a leaking skylight that was incorrectly mounted. They also re-shingled the entire portion of that roof and replaced a couple of vents. They were able to get in 24-48 hours after I called to look at it. My only gripe is they said they would show up on Wednesday but they showed up early on Tuesday instead, so I had to re-do my schedule at the last minute. Once they got in though, the work was phenomenally fast, phenomenally affordable, and phenomenally good.
