The local roofers have been pushing BP Harmony. The local home improvement suppliers typically offered BP and IKO laminated shingles. I did my research and went with Certainteed Landmark (keeping fingers crossed). Almost went with GAF/ELK, but it was tough finding colours for my region.
Also, I went with Certainteed Winterguard for the ice and water shield...up 7 feet from the eaves. Nova Seal for the underlay. 4/12 pitch.
