Anyone here have any experience with CertainTeed Northgate shingles? The SBS modified asphault seams to be VERY flexible and compared to GAF Timberlines are heavier and thicker and a LOT harder to tear. When I bent the GAF (and also an IKO) the grit came off and the backing cracked - the NorthGate bent with no cracking and no grit loss.
I was realling considering putting on steel - but at 13000-14000 for the steel, 7000 for the Northgate looks pretty good - both with 50 year non pro-rated full replacement warranty . The GAF or IKO (or Certainteed Landmark) Roof would run about 6000 with 30 year "dissapearing ink" warranty.
I know Certainteed had a LOT of trouble with their low end Landmark shingles a decade or so ago, but their higher end products seemed to be pretty good.So no, I don't need any reference to the problems with Landmark and the contractor I'm talking to has 30 years experience - over 20 with Certainteed, and his Dad has been in the business for over 40 years.The son also does steel and all 3 prices are from him. I got a steel quite from another local company with the same product as one of his steel quotes and he was 1000 better than the other company - with all the same installation specs. Interestingly the stone-coat steel, although more expensive product, came out cheaper because it does not require the snow guards the bare Kynar steel needs
