No sign of getting Rid of GAF around here, the sale I see is $22-23 for 3 tab and $26 and change for Timberlines, not a bad deal. Not sure if HD offers rooftop delivery around here.
I see no difference in the quality or the packaging in Timberlines that were bought from HD vs. Allied Supply. I don't generally do roofs outside of the occasional skylight install, but I recently re-roofed my own house, ran 2 bundles short, so I picked up 2 from HD. No diff from the 14 sq I got from Allied.
To do it agian, I probably would have gone with OC duration or Oakridge as they seem a bit thicker for the same money.
I can't see HD going OC because it doesn't make good business sense. HD and lowes always carry competing brands, for example Pella Vs. Anderson, USP Hardware vs. Simpson, Johns Manville vs. CT, etc.
