Cedar shake roofs can last 30 plus years; however, they do require routine repairs & maintenance in order to maximize the life expectancy of the roof. Composite roofing materials in contrast, do not require routine maintenance. Composite roofing resists rotting, cupping, curling, insects, and ongoing decay that can often occur within a cedar roof. Composite roofs help provide peace of mind in knowing that the roof does not need to be routinely maintained. All backed by a Lifetime Limited Material Warranty.
