Update Two Years Later:
The shingle install has been sound so far but the re-installation of my metal leaf guard wasn't done correctly. I sent Koast a video of the waterfall my eaves experienced during heavy rains & he said he would fix it when he was in the area. I called & emailed Koast repeatedly, not that I should have to, to stay on his radar but, after Two Years(!) the correction was never done.
I just finished clearing out all the sludge (including a birds nest!) that has accumulated over the two years.
Sorry Koast, everything was great up until your inability to take responsibility for and fix your mistakes. Thank goodness I haven't had an issue with the shingles, I feel I'd have been left in the lurch with that too. :-(
Koast and his crew were all very professional and a pleasure to work with! Koasts quote was competitively priced and didnt take advantage of the fact I had a leak. He did his best to fit me in as soon as possible which I very much appreciated. He was flexible with some additional things I needed done and was very accessible throughout the process of figuring out how to proceed. Hes a good communicator and I felt very well taken care of! I also appreciated how well they cleaned up well after themselves.
Im only too happy to recommend this company so others can also have a positive roofing experience!
