Manufacturers work hard to provide homeowners with the best roofing solutions. They make modern roofing from laminated compounds with color added. There are two basic types, which are essentially either a single-layer or a double-layer roofing tile. The double-layer roof tile is the architectural or dimensional type. The single layer is the three-tab version.
The architectural type is costlier but more appealing to the eye, and it can add value to your home. The single-layer type or three-tab tile is a basic roof cover. It has a flat appearance, and the tiles are consistent in size and shape.
Construction of Asphalt Roofing
The inner core of each tile is a piece of fiberglass. The fiberglass is water-resistant and provides some insulation. The maker then sandwiches the sheet of fiberglass between two weatherizing layers. Next, the top layer receives a covering of mineral granules, which add texture and color.
The architectural type of roof tile is a double of the four composite layers. The lower edge of the architectural tile has a raised laminated ridge. This raised section adds to the appearance of depth.
The double-layer composite tile is a popular roof cover. Manufacturers call it architectural or dimensional roofing. You can distinguish the architectural type from a three-tab or single-layer tile by its size, weight, durability, and appearance.
Asphalt is the base material for architectural or double roofing and the 3-tab types. In the early 1980s, technical advances in lamination and materials created the architectural type. From that time to the present, architectural types have replaced tabs as the preferred material for roofing installations. Today, the traditional three-tab type of roofing is the low-cost option and the required material to repair roofs that already have tab shingles.
