Gaf Roofing

My house needs a new roof and I am able to get a good price on some shingles GAF basis of a local property manager. I researched and found that GAF had complaints with its base tile (cheap) in the past. Has anyone had recent experience (5 years) with them? Are the packages marked with a date code? If so, how do you read the code? That way you can prevent shingles was problem-prone. I know I should not be priced only for shingles, but are tight financially. Thank you. From what I can tell … The lid [packaging] should have a date of manufacture
