Alpine Roofing

I am not a roofer, and therefore cannot judge the quality of roofing workmanship directly. However, because of those things that I did observe, I am confident that George and Andreas did an excellent job. George, for example, spent quite a long time in an uncomfortable position to ensure that the flashing and shingling under an overhang was done properly. Our kitchen range hood requires an 8" diameter duct through the attic to the roof. The ducting was only 6 years old. I asked George to re-use the existing roof vent. He did not seem happy about this. I then asked Derek to call him and tell him the same thing. A few hours later, George came in and showed me the new vent he was going to install, because there had been leaking in that area, of which I was not aware. He could simply have said to himself, "Everybody insists on not replacing the vent, so I can safely ignore it." Instead, he insisted on replacing it, so that the leak would be eliminated. The other way to judge quality is from the cleanup. Everything was left spotless. We could not find a single nail. Andreas climbed up and down the steep ravine behind our house to retrieve wind-blown bits of plastic. Andreas climbed a tree to do the same. Based on our non-professional observations, we believe that the workmanship was excellent.
