Got my first bid and truely liked the GC (not a roofing specialist but presented himself in a helpful and knowledgeable way; confirmed 4th generation contractor he claimed to be).
He gave good advice pointing out that because of my low pitch, I won’t get much of the asthetic benefit that comes with the higher priced shingles (seems to be 5/12 if I measured right); also said that difference between 30 and Ultra will be strength and ability to stay intact but they’ll each look weathered about the same over time.
I’m interested in the GAF Slateline primarily for very solid Consumer Reports for strength, wind and weathering ratings. After meeting with the contractor I checked the sq weights (per ConsReport) and it says the Slatleine is 247, GAF 30 yr are 269 and Landmark 30 are 242. Is it a fair conclusion to say I’d have a little more concern with sheathing imperfections with the Landmark and slightly less concern with the GAF 30? Would bumping either of these up to the Ultra line give me a significant enough likely shot at avoiding this concern? Or should I just go the other way with a 3 tab that (dare I say) could be layed over 15-20 years from now when I’ll likely be out of here? Please note that I’m doing it right this time by doing a tear-off, W+I and proper ventilation.
Cost diff to go Slateline over either 30 year is $600. If either of the 30s introduce the same chance of noticing imperfections, I’m thinking the Slateline are worth it to get the better ratings. Going with a 3-Tab is also not out of the question. Can you pros offer this girl helpful opinions? I’ll be out of here in 15-20 years.
