The crew was here in 2008. They stripped our old house roof off (two layers). They put on nice architectural roof shingles on the bare roof (with very high ice dam water proofing all around) on our house+addition (added ridge venting) and then covered our 24x24 garage. Today (10/5/2015), All the roofs still look almost like new.. No leaks or any other problems. No call backs were needed.. Since 2008, we've had some major snow build up. So, I've been using a snow rake to remove a few feet of snow from the roofs a few times.. It's an aluminum rake, but so far it has not damaged the shingles. I told Scott that we would be a reference if he ever needed to show his work to anyone. So, if you want to see how our 2008 roof looks today, he has our address.. Cheers, Rich
