I love the look but I fear that they will be very labor intensive. These are not the cedar shakes but the flat cedar shingles. The installer is telling me that all I really need to do is spray them down once per year with a decking treatment and this will be enough to preserve them for many years and ensure that mildew would not grow. I do have tree's on all sides of my house and the pitch is 8/12. My roof would receive about 4-5 hours of sunlight a day. Also, he is stating that he would lay tar paper down then a vapor barrier then the shingles. He also is stating that cedar shingles (not shakes) do not curl up. For 33 squares installed we are looking at $10,500 vs $5,100 for 40 year ashpalt 3d. My questions are this: Are cedar shingles more labor intensive? Will cedar greatly increase the value of my home over ashpalt? Any help would be greatly appreciated. Thanks!
