Thank you for kindly running some numbers and suggesting possible shingle options.
The Certainteed Presidential and other links are very much appreciated, yet make only a generic effort to replicate cedar shingles… somehow missing the mark.
For me it is important that the project have design integrity, so maybe I will simply have to revert to the closest 30-year shingle in color and modulation, replicating what is currently on the roof.
Thank you for your remarkable professional support and keen insights… your great karma will serve you well, as it is so conspicuously absent from many relationships today… kudos…you must have had inspired parents!!!
