Alpine roofing was available when I needed them, and responded very quickly to quote and complete my roof (1 point).
Immediate reaction: The roof looked very good, and I could tell the shingles would last for a long time. The team assigned to our home were very messy, and left an absolute pile of garbage behind after the job. They did not tarp-off the area around our home, so even today I am out picking up roofing nails and shingle pieces from our flower-beds and grass... Make sure you are clear that they need to clean-up after themselves and use tarps to cover the area surrounding the home.
UPDATE: Since the install we have had a couple of leaks... They did not put flashing around our dormers, and the shingles were poorly installed near the eaves (we have had major pest problems since the new roof went on). Although they did come back for some follow-up work, we will be getting another company back to remedy their issues. Would not recommend...
