Architectural roofing shingles provide a stunning three-dimensional appearance. Some of the most attractive architectural roofing shingles simulate cedar wood shakes (such as CertainTeed’s Presidential Shake TL and Presidential Shake shingles). These shingles are quite thick with random slots similar to real shakes. Another unique architectural shingle design imitates the look of slate (such as CertainTeed’s Symphony Slate, Grand Manor, Centennial Slate or Carriage House shingles) without the weight issues that normally accompany those materials. These architectural roofing shingles do not require any additional roof support as slate would.
