[Master of None]

This past winter I lost a few shingles off of my roof. About a 8'x 8' area. The roof is about 13 years old. I would like to replace the missing shingles with the same color shingle. I found out that the old shingles were the brand 'Rain Bird?'. I can not find a shingle that matches the old ones, talking to contractors and supply houses. Can anyone tell me how to go about finding a match?

Any help will be appreciated

Thanks
