This is a roof that we went over in South Burlington
The old shingles on this roof have been there for 22 years and never leaked but the home owner wanted to update them to newer style to make his house look better and to refresh his 30 year warranty for his roof. Guess he didnt know that going over another layer of shingles reduces the warrenty life of the new shingles.
Below is a close up shot of the AR Architechual shingles, they are pretty much a double layer shingle unlike the older 3 tab shingle which is only one layer. Architechual shingles are what people prefer now because they bring the roof to life. AR means algea resistant, this means that you will not have moss or black water marks on your roof at all and if you ever look at some roofs and they have these marks then they are not AR shingles.
