MaxiTile has the feel and look of clay tile, but it’s about 65 percent lighter (340 pounds per square). That makes it ideal for reroofing projects. Figure 5-9 shows their SuperTile, which has been in production since the 1920s. The tiles are composed of portland cement, silica sand, and treated cellulose fibers (no recycled materials), and they’re colored all the way through.

The cellulose fibers from harvested trees are fabricated into strands, laid out in a grid pattern, and laminated to the required thickness. This process gives it strength, so the tile can be thinner and lighter than clay or concrete tiles. To achieve overall structural strength, the tiles are steam cured under pressure in an autoclave (pressurized chamber). MaxiTile carries a 50-year transferable limited warranty, but it’s not warranted against freeze-thaw damage. The company prefers that you call for geographical clarification. You can get a Class A fire rating when you install a 72- or 90-pound granulated felt with the granules up. The maximum roof pitch is 21:12 (I think I’d sub that one out!) with the minimum 3:12. Below that, it requires an approved sealed membrane. MaxiTile is available in the form of a shake, slate, and Spanish tile in a variety of earthtone colors.
