Thank you, all of you for your input. I took the pictures separately from the folder I had and each individually exceeds the maximum kb range. I will send pictures to Doc and TRG. I would appreciate your advise on what shingle to purchase and which to avoid next time. I enjoy your humor. I too have a full time life and job too and am grateful that you are willing to take your time to help me. My roofer is licensed, insured, member of BBB. I did my research before I chose which roofer to use, but I didn't research products, just told him I wanted maximum life, high wind resistant and mold inhibitors (since I live in a highly wooded area). I will speak to an attorney depending upon CertainTeed's response to my certified mail and warranty claim. My warranty does not require that CertainTeed products are used in replacement, so now after all this gravel loss, I'm searching for a better product.
By way of more thorough step by step review, this brings the shorter version up to date below.
On May 9, 2005 (2 yrs ago), contractors completed replacement of all roofing materials which included your 50 year warranty algae resistant Landmark shingles. In addition to installation of roofing materials, all gutters were removed, cleaned, and reinstalled following the completion of shingle placement. In the weeks that followed, shingle grit/gravel began to appear on the ground at each downspout. I considered the possibility that this might be due to the contractors walking on the roof during installation followed by seasonal rain.
Every fall all gutters are cleaned of leaf debris for the upcoming winter. In September, 2005 (4 months following installation), I noted a significant amount of shingle grit/gravel remaining in the gutters, which had not washed out through the downspouts.
In the fall of 2006, all gutters were once again cleared and rinsed. Shingle grit/gravel was present in the gutters again. No one had been on my roof between the fall gutter cleaning of 2005 and fall of 2006, so the additional loss of shingle gravel was not due to any contractors.
This summer (2007), I arranged for painting contractors to prep and paint my home. I paid my roofing contractor to remove all gutters (which were placed on the ground away from the house), so that the painting contractors could prep and paint all wood surfaces, even surfaces which were not readily visible (a very thorough job), as the wood surfaces behind the gutters.
At various times, the painting job was delayed, due to rain or high humidity. Since the gutters were not lying at a proper drain pitch, they filled with water, which if left filled, would perhaps contaminate and become a short term breeding ground for mold/algae and mosquitoes. I turned all of the gutters over to drain the water out until the gutters could be reinstalled. As I did so, more shingle grit/gravel poured out onto the ground from each gutter.
Thanks guys. Perhaps doc or TRG can upload some of these or comment on the pics sent to them.
