“Tile or concrete” roofs are very beneficial for having a maintenance free roof that is the most durable in most climates but is the most expensive. The extra costs involved in these types of roofs are labor to install, roof materials and the labor costs to support the weight of the heavy tile roofs. Also consider the fact that they are not easy to walk on once installed and a trained professional can walk on them without damaging the tiles. Warranties for Tile or concrete roofs range from 40 years to lifetime.
“Metal roofs” are in the mid-range of roof replacements and can be installed over 1 layer of asphalt shingles. Most homes in higher elevation use metal roofs to allow the snow to run off higher pitched roofs. Metal roofs come in many assorted styles and available in any color.
