I will keep the insurance /contractor info limited in this post since this is primary a shingle related question. However some background would help with my question:
I am located in central NC and several homes in the area had roof damage due to a hail storm a year or so ago (some neighbors were getting new roofs). Talked to a couple companies. Company A (referral) game by to do a preliminary inspection (did not find any hail damage- however they did not go on the roof). Several months ago I decided I would have another company come by (Company B- reputable company) who did a preliminary inspection and found hail damage. Filed a claim, insurance adjuster did his thing (with roofing company B present) and basically got a $ for new roof (minus deductible of course). I signed a construction contract with Company B (who are GAF certified) and use GAF Timberline HDZ as their standard shingles. I did recently talk to company A who now is more than happy to take the job telling me they use better shingles (CertainTeed Landmark) which they can upgrade me at no or very minimal cost to CertainTeed Landmark Pro. Talking to Company A and doing research I learn that Timberline HDZ weigh only 210 lbs per square and the CertianTeed Landmark/Pro at 225 lbs and 250 lbs respectively and due to their volume discounts that upgrading to the pro only costs them something like $15 per square. The issue is that going to a better shingle with company B (Timberline UHD) is a premium and most likely not in the budget especially since having a large deductible. My concern is that the landmark pro appears to be the heavier (thicker) shingle that may give me more usable years on the new roof. Should I be concerned or just go with the Timberline HDZ and be done with it.
