Asphalt Shingles (Standard)Not all asphalt shingles are created alike.We use architectural grade IKO shingles, where each shingle has multiple layers that help add to the roof durability and add visual interest with resulting shadow lines. Special color treatments on the shingles add to the effect. The shingles we use are the same as used on many single family and multi-family homes. They are made with three layers: a fiberglass-reinforced organic felt materia, saturated with asphalt, then a thick ashpalt layer, then stone granules.
