CertainTeed is the third-largest US asphalt manufacturer and arguably the strongest in the heritage / luxury asphalt category. Landmark is the workhorse line; Landmark Pro and Landmark Premium offer thicker, more dimensional aesthetics; Highland Slate and Presidential Shake serve the Eastmoreland/Laurelhurst heritage market. The installer credential tiers (Quality Master / ShingleMaster / SELECT ShingleMaster) are the most demanding of the major manufacturers.
CertainTeed's product hierarchy centers on Landmark — an architectural shingle line with a 110 mph wind rating standard, upgradeable to 130 mph with the StreakFighter algae warranty. Landmark Pro is the thicker premium version with deeper shadow line; Landmark Premium is the thickest mass-market option. Above Landmark sit the designer lines: Highland Slate (synthetic slate look, common on heritage homes), Presidential Shake (luxury 50-year), and Grand Manor (the heaviest mass-market designer shingle, 7-tab construction).
