CertainTeed Landmark TLWhat are CertainTeed Landmark TL asphalt shingles?  The TL stands for Triple Laminate.  This advance asphalt shingle is heavy duty and the three thick layers provide an asphalt shingle that is reminiscent of traditional cedar shake roofing.  Tri-laminate technology provides superior performance, especially because these layers are manufactured from the industry’s most durable materials.

  •  Thick tri-laminate layers create a thick roofing shingle reminiscent of cedar shakes, while providing tough, superior durability.
  •  Landmark TL is installed with a random tab design, producing natural shadows and aesthetic beauty to provide character to your roof.
